- Amnesteem and accutane



  (Isotretinoin Capsules). Read the Medication Guide that comes with Amnesteem before you start taking it and each time you get a prescription. Isotretinoin, USP a retinoid, is available as Amnesteem (isotretinoin capsules, USP) in 10 mg, 20 mg and 40 mg soft gelatin capsules for oral administration. Isotretinoin is available in capsule form and is used to treat severe nodular acne. It works by reducing the amount of oil released by glands in your skin and.

Cutaneous allergic reactions and serious cases of allergic vasculitis, often with purpura bruises and red patches of the extremities and extracutaneous involvement including renal have been reported. Severe allergic reaction necessitates discontinuation of therapy and appropriate medical management. Pretreatment and follow-up blood lipids should be obtained under fasting conditions. After consumption of alcohol, at least 36 hours should elapse before these determinations are made.

It is recommended that these tests be performed at weekly or biweekly intervals until the lipid response to Amnesteem is established. Since elevations of liver enzymes have been observed during clinical trials, and hepatitis has been reported, pretreatment and follow-up liver function tests should be performed at weekly or biweekly intervals until the response to Amnesteem has been established see WARNINGS: Hepatotoxicity.

Some patients receiving Amnesteem have experienced problems in the control of their blood sugar. In addition, new cases of diabetes have been diagnosed during Amnesteem therapy, although no causal relationship has been established. Some patients undergoing vigorous physical activity while on Amnesteem therapy have experienced elevated CPK levels; however, the clinical significance is unknown.

There have been rare post-marketing reports of rhabdomyolysis, some associated with strenuous physical activity. In these patients, approximately half of the CPK elevations returned to normal within 2 weeks and half returned to normal within 4 weeks. No cases of rhabdomyolysis were reported in this trial. The incidence of adrenal medullary hyperplasia was also increased at the higher dosage in both sexes.

The relatively high level of spontaneous pheochromocytomas occurring in the male Fischer rat makes it an equivocal model for study of this tumor; therefore, the relevance of this tumor to the human population is uncertain. The Ames test was conducted with isotretinoin in two laboratories. The results of the tests in one laboratory were negative while in the second laboratory a weakly positive response less than 1. No dose-response effect was seen and all other strains were negative.

Additionally, other tests designed to assess genotoxicity Chinese hamster cell assay, mouse micronucleus test, S. In general, there was microscopic evidence for appreciable depression of spermatogenesis but some sperm were observed in all testes examined and in no instance were completely atrophic tubules seen. In studies of 66 men, 30 of whom were patients with nodular acne under treatment with oral isotretinoin, no significant changes were noted in the count or motility of spermatozoa in the ejaculate.

In a study of 50 men ages 17 to 32 years receiving Amnesteem therapy for nodular acne, no significant effects were seen on ejaculate volume, sperm count, total sperm motility, morphology or seminal plasma fructose. It is not known whether this drug is excreted in human milk. Because of the potential for adverse effects, nursing mothers should not receive Amnesteem.

The use of Amnesteem in pediatric patients less than 12 years of age has not been studied. Clinical studies of isotretinoin did not include sufficient numbers of subjects aged 65 years and over to determine whether they respond differently from younger subjects. The adverse reactions listed below reflect the experience from investigational studies of Amnesteem, and the post-marketing experience.

The relationship of some of these events to Amnesteem therapy is unknown. Many of the side effects and adverse reactions seen in patients receiving Amnesteem are similar to those described in patients taking very high doses of vitamin A dryness of the skin and mucous membranes, e. Cheilitis and hypertriglyceridemia are usually dose related. Cardiovascular: palpitation, tachycardia, vascular thrombotic disease, stroke. Neurological: pseudotumor cerebri see WARNINGS: Pseudotumor Cerebri , dizziness, drowsiness, headache, insomnia, lethargy, malaise, nervousness, paresthesias, seizures, stroke, syncope, weakness.

Of the patients reporting depression, some reported that the depression subsided with discontinuation of therapy and recurred with reinstitution of therapy. Respiratory: bronchospasms with or without a history of asthma , respiratory infection, voice alteration. In humans, overdosage has been associated with vomiting, facial flushing, cheilosis, abdominal pain, headache, dizziness, and ataxia.

These symptoms quickly resolve without apparent residual effects. Patients who can become pregnant who present with isotretinoin overdose must be evaluated for pregnancy. Educational materials for such patients can be obtained by calling the manufacturer. Because an overdose would be expected to result in higher levels of isotretinoin in semen than found during a normal treatment course, male patients should use a condom, or avoid reproductive sexual activity with a patient who is or might become pregnant, for one month after the overdose.

All patients with isotretinoin overdose should not donate blood for at least one month. The recommended dosage range for Amnesteem is 0. In studies comparing 0. Failure to take Amnesteem with food will significantly decrease absorption. Before upward dose adjustments are made, the patients should be questioned about their compliance with food instructions. The safety of once daily dosing with Amnesteem has not been established. Once daily dosing is not recommended. After a period of 2 months or more off therapy, and if warranted by persistent or recurring severe nodular acne, a second course of therapy may be initiated.

The optimal interval before retreatment has not been defined for patients who have not completed skeletal growth. Long-term use of Amnesteem, even in low doses, has not been studied, and is not recommended. Amnesteem must only be dispensed in no more than a day supply. This Amnesteem Medication Guide is an important part of the risk management program for the patient. The 20 mg capsules are reddish brown and cream and imprinted with I They are available as follows:.

Read the Medication Guide that comes with Amnesteem before you start taking it and each time you get a prescription. There may be new information. This information does not take the place of talking with your doctor about your medical condition or your treatment. After stopping Amnesteem, you may also need follow-up mental health care if you had any of these symptoms. Amnesteem is a medicine taken by mouth to treat the most severe form of acne nodular acne that cannot be cleared up by any other acne treatments, including antibiotics.

Amnesteem can only be:. Severe nodular acne is when many red, swollen, tender lumps form in the skin. These can be the size of pencil erasers or larger. If untreated, nodular acne can lead to permanent scars. Tell your doctor if you or a family member has any of the following health conditions:.

Tell your doctor if you are pregnant or breast-feeding. Amnesteem must not be used by patients who are pregnant or breast-feeding. Tell your doctor about all of the medicines you take including prescription and non-prescription medicines, vitamins and herbal supplements.

Amnesteem and certain other medicines can interact with each other, sometimes causing serious side effects. Especially tell your doctor if you take:. These medicines should not be used with Amnesteem unless your doctor tells you it is okay. Know the medicines you take. Keep a list of them to show to your doctor and pharmacist. Do not take any new medicine without talking with your doctor.

You must talk about effective birth control forms with your doctor or go for a free visit to talk about birth control with another doctor or family planning expert. Your doctor can arrange this free visit, which will be paid for by the company that makes Amnesteem. If you have sex at any time without using two forms of effective birth control, get pregnant, or miss your expected period, stop using Amnesteem and call your doctor right away.

Table 1. Nodular Acne Clinical improvement in nodular acne patients occurs in association with a reduction in sebum secretion. Pharmacokinetics Absorption Due to its high lipophilicity, oral absorption of isotretinoin is enhanced when given with a high-fat meal. Table 2. Distribution Isotretinoin is more than Metabolism Following oral administration of isotretinoin, at least three metabolites have been identified in human plasma: 4- oxo -isotretinoin, retinoic acid tretinoin , and 4- oxo -retinoic acid 4- oxo -tretinoin.

Elimination Following oral administration of an 80 mg dose of 14 C-isotretinoin as a liquid suspension, 14 C-activity in blood declined with a half-life of 90 hours. Table 3. Severe Recalcitrant Nodular Acne Amnesteem is indicated for the treatment of severe recalcitrant nodular acne. Pseudotumor Cerebri Amnesteem use has been associated with a number of cases of pseudotumor cerebri benign intracranial hypertension , some of which involved concomitant use of tetracyclines.

Serious Skin Reactions There have been post-marketing reports of erythema multiforme and severe skin reactions [e. Pancreatitis Acute pancreatitis has been reported in patients with either elevated or normal serum triglyceride levels. The cardiovascular consequences of hypertriglyceridemia associated with Amnesteem are unknown.

Hearing Impairment Impaired hearing has been reported in patients taking Amnesteem; in some cases, the hearing impairment has been reported to persist after therapy has been discontinued.

Hepatotoxicity Clinical hepatitis considered to be possibly or probably related to Amnesteem therapy has been reported. Inflammatory Bowel Disease Amnesteem has been associated with inflammatory bowel disease including regional ileitis in patients without a prior history of intestinal disorders. Skeletal Bone Mineral Density Effects of multiple courses of Amnesteem on the developing musculoskeletal system are unknown.

Hyperostosis A high prevalence of skeletal hyperostosis was noted in clinical trials for disorders of keratinization with a mean dose of 2. Premature Epiphyseal Closure There are spontaneous reports of premature epiphyseal closure in acne patients receiving recommended doses of Amnesteem.

Vision Impairment Visual problems should be carefully monitored. Corneal Opacities Corneal opacities have occurred in patients receiving Amnesteem for acne and more frequently when higher drug dosages were used in patients with disorders of keratinization. Decreased Night Vision Decreased night vision has been reported during Amnesteem therapy and in some instances the event has persisted after therapy was discontinued.

Prescribers To prescribe isotretinoin, the prescriber must be enrolled and activated with the pregnancy risk management program iPLEDGE. Patients should have a pregnancy test at the completion of the entire course of isotretinoin and another pregnancy test one month later. The patient must sign the informed consent form before starting treatment and patient counseling must also be done at that time and on a monthly basis thereafter.

The first test a screening test is obtained by the prescriber when the decision is made to pursue qualification of the patient for isotretinoin. The second pregnancy test a confirmation test must be done in a CLIA-certified laboratory. The interval between the two tests should be at least 19 days.

A pregnancy test must be repeated every month, in a CLIA-certified laboratory, prior to the patient who can become pregnant receiving each prescription. Patients must use two forms of effective contraception for at least one month prior to initiation of isotretinoin therapy, during isotretinoin therapy, and for one month after discontinuing isotretinoin therapy.

Counseling about contraception and behaviors associated with an increased risk of pregnancy must be repeated on a monthly basis. If the patient has unprotected sexual contact with a partner that could result in pregnancy at any time one month before, during, or one month after therapy, the patient must: 1.

Stop taking Amnesteem immediately, if on therapy 2. Have a pregnancy test at least 19 days after the last act of unprotected sexual contact with a partner that could result in pregnancy 3. Start using two forms of effective contraception simultaneously again for one month before resuming Amnesteem therapy 4. Have a second pregnancy test after using two forms of effective contraception for one month as described above depending on whether the patient has regular menses or not.

All Patients Isotretinoin is contraindicated in patients who are pregnant. Patients Who Become Pregnant Isotretinoin is contraindicated in patients who are pregnant. Authorization signifies that the patient has met all program requirements and is qualified to receive Amnesteem. This handout is provided to both the patient who can become pregnant and the patient who cannot become pregnant.

General Although an effect of Amnesteem on bone loss is not established, physicians should use caution when prescribing Amnesteem to patients with a genetic predisposition for age related osteoporosis, a history of childhood osteoporosis conditions, osteomalacia, or other disorders of bone metabolism.

The complete text of the Medication Guide is reprinted at the end of this document. They should also sign a second Patient Enrollment Form for Patients who can get Pregnant prior to beginning Amnesteem therapy. While the no-effect limit for isotretinoin induced embryopathy is unknown, 20 years of post-marketing reports include four with isolated defects compatible with features of retinoid exposed fetuses; however two of these reports were incomplete, and two had other possible explanations for the defects observed.

Therefore, prior to initiation of Amnesteem treatment, patients and family members should be asked about any history of psychiatric disorder, and at each visit during treatment patients should be assessed for symptoms of depression, mood disturbance, psychosis, or aggression to determine if further evaluation may be necessary.

Signs and symptoms of depression include sad mood, hopelessness, feelings of guilt, worthlessness or helplessness, loss of pleasure or interest in activities, fatigue, difficulty concentrating, change in sleep pattern, change in weight or appetite, suicidal thoughts or attempts, restlessness, irritability, acting on dangerous impulses, and persistent physical symptoms unresponsive to treatment.

Discontinuation of Amnesteem treatment may be insufficient; further evaluation may be necessary. Some patients taking Amnesteem have had thoughts about hurting themselves or putting an end to their own lives suicidal thoughts. Some people tried to end their own lives. And some people have ended their own lives. There were reports that some of these people did not appear depressed. There have been reports of patients on Amnesteem becoming aggressive or violent.

No one knows if isotretinoin caused these behaviors or if they would have happened even if the person did not take Amnesteem.

Some people have had other signs of depression while taking Amnesteem. To decrease the risk of esophageal irritation, patients should swallow the capsules with a full glass of liquid. In general, these symptoms were mild to moderate, but occasionally required discontinuation of the drug. Transient pain in the chest has been reported less frequently. There have been rare post-marketing reports of rhabdomyolysis, some associated with strenuous physical activity see Laboratory Tests: CPK.

Back pain was severe in Arthralgias were severe in 7. Appropriate evaluation of the musculoskeletal system should be done in patients who present with these symptoms during or after a course of Amnesteem. Consideration should be given to discontinuation of Amnesteem if any significant abnormality is found.

Amnesteem should be discontinued if clinically significant decreases in white cell counts occur. Amnesteem should be discontinued if clinically significant skin reactions occur. Hypersensitivity Anaphylactic reactions and other allergic reactions have been reported. These reports are more frequent for patients who can become pregnant who use only a single form of contraception.

It is not known if hormonal contraceptives differ in their effectiveness when used with Amnesteem. Prescribers are advised to consult the package insert of medication administered concomitantly with hormonal contraceptives, since some medications may decrease the effectiveness of these birth control products.

John's Wort. These results are consistent with the in vitro finding that neither isotretinoin nor its metabolites induce or inhibit the activity of the CYP 2C9 human hepatic P enzyme. Phenytoin is known to cause osteomalacia. No formal clinical studies have been conducted to assess if there is an interactive effect on bone loss between phenytoin and Amnesteem. Therefore, caution should be exercised when using these drugs together. No formal clinical studies have been conducted to assess if there is an interactive effect on bone loss between systemic corticosteroids and Amnesteem.

The first test a screening test is obtained by the prescriber when the decision is made to pursue qualification of the patient for Amnesteem. The interval between the two tests must be at least 19 days. A pregnancy test must be repeated each month, in a CLIA-certified laboratory, prior to the patient who can become pregnant receiving each prescription. Lipids Pretreatment and follow-up blood lipids should be obtained under fasting conditions.

Liver Function Tests Since elevations of liver enzymes have been observed during clinical trials, and hepatitis has been reported, pretreatment and follow-up liver function tests should be performed at weekly or biweekly intervals until the response to Amnesteem has been established see WARNINGS: Hepatotoxicity. Glucose Some patients receiving Amnesteem have experienced problems in the control of their blood sugar. CPK Some patients undergoing vigorous physical activity while on Amnesteem therapy have experienced elevated CPK levels; however, the clinical significance is unknown.

Nursing Mothers It is not known whether this drug is excreted in human milk. Pediatric Use The use of Amnesteem in pediatric patients less than 12 years of age has not been studied. Geriatric Use Clinical studies of isotretinoin did not include sufficient numbers of subjects aged 65 years and over to determine whether they respond differently from younger subjects. Clinical Trials and Post-marketing Surveillance The adverse reactions listed below reflect the experience from investigational studies of Amnesteem, and the post-marketing experience.

I understand that there is a very high chance that my unborn baby could have life threatening birth defects if I am pregnant or become pregnant while taking isotretinoin.

This can happen with any amount and even if taken for short periods of time. This is why I must not be pregnant while taking isotretinoin.

I understand that I must not get pregnant one month before, during the entire time of my treatment, and for one month after the end of my treatment with isotretinoin. I understand that I must avoid having any sexual contact penis-vaginal with a partner who could get me pregnant completely, or I must use two separate, effective forms of birth control contraception at the same time.

The only exceptions are if I have had surgery to remove the uterus a hysterectomy or both of my ovaries bilateral oophorectomy , or my doctor has medically confirmed that I am post-menopausal. I understand that hormonal birth control products are among the most effective forms of birth control. Combination birth control pills and other hormonal products include skin patches, shots, under-the-skin implants, vaginal rings, and intrauterine devices IUDs.

Any method of birth control can fail. That is why I must use two different birth control forms at the same time, starting one month before, during, and for one month after stopping therapy every time I have any sexual contact penis-vaginal with a partner who could get me pregnant, even if one of the forms I choose is hormonal birth control.

What is the most important information I should know about Amnesteem? Birth defects deformed babies , loss of a baby before birth miscarriage , death of the baby, and early premature births.

Patients who are pregnant or who plan to become pregnant must not take Amnesteem. If you get pregnant while taking Amnesteem, stop taking it right away and call your doctor. Serious mental health problems.

Amnesteem and accutane. CONTRAINDICATIONS AND WARNINGS



    These reports are more frequent for patients who can become pregnant who use only a single form of contraception. Cases of IQ scores less than 85 with or without other abnormalities have been reported. These events may be serious and result in death, life-threatening events, hospitalization, or disability. Meeting the requirements for a patient who can become pregnant signifies that the patient:. Vitamin A in high doses has many of the same side effects as Amnesteem.

Isotretinoin is a retinoid, which when administered in pharmacologic dosages of 0. The exact mechanism of action of isotretinoin is unknown. Clinical improvement in nodular acne patients occurs in association with a reduction in sebum secretion. The decrease in sebum secretion is temporary and is related to the dose and duration of treatment with Amnesteem, and reflects a reduction in sebaceous gland size and an inhibition of sebaceous gland differentiation.

Due to its high lipophilicity, oral absorption of isotretinoin is enhanced when given with a high-fat meal. In a crossover study, 74 healthy adult subjects received a single 80 mg oral dose 2 x 40 mg capsules of Amnesteem under fasted and fed conditions. Both peak plasma concentration C max and the total exposure AUC of isotretinoin were more than doubled following a standardized high-fat meal when compared with Amnesteem given under fasted conditions see Table 2.

The observed elimination half-life was unchanged. This lack of change in half-life suggests that food increases the bioavailability of isotretinoin without altering its disposition. The time to peak concentration T max was also increased with food and may be related to a longer absorption phase. Clinical studies have shown that there is no difference in the pharmacokinetics of isotretinoin between patients with nodular acne and healthy subjects with normal skin.

Following oral administration of isotretinoin, at least three metabolites have been identified in human plasma: 4- oxo -isotretinoin, retinoic acid tretinoin , and 4- oxo -retinoic acid 4- oxo -tretinoin. Retinoic acid and cis -retinoic acid are geometric isomers and show reversible interconversion. The administration of one isomer will give rise to the other. Isotretinoin is also irreversibly oxidized to 4- oxo -isotretinoin, which forms its geometric isomer 4- oxo -tretinoin.

After a single 80 mg oral dose of Amnesteem to 74 healthy adult subjects, concurrent administration of food increased the extent of formation of all metabolites in plasma when compared to the extent of formation under fasted conditions. All of these metabolites possess retinoid activity that is in some in vitro models more than that of the parent isotretinoin. However, the clinical significance of these models is unknown. In vitro studies indicate that the primary P isoforms involved in isotretinoin metabolism are 2C8, 2C9, 3A4, and 2B6.

Isotretinoin and its metabolites are further metabolized into conjugates, which are then excreted in urine and feces. Following oral administration of an 80 mg dose of 14 C-isotretinoin as a liquid suspension, 14 C-activity in blood declined with a half-life of 90 hours. After both single and multiple doses, the observed accumulation ratios of isotretinoin ranged from 0. In both age groups, 4- oxo -isotretinoin was the major metabolite; tretinoin and 4- oxo -tretinoin were also observed.

The dose-normalized pharmacokinetic parameters for isotretinoin following single and multiple doses are summarized in Table 3 for pediatric patients. There were no statistically significant differences in the pharmacokinetics of isotretinoin between pediatric and adult patients.

The accumulation ratios of isotretinoin ranged from 0. Amnesteem is indicated for the treatment of severe recalcitrant nodular acne. Nodules are inflammatory lesions with a diameter of 5 mm or greater.

The nodules may become suppurative or hemorrhagic. Because of significant adverse effects associated with its use, Amnesteem should be reserved for patients with severe nodular acne who are unresponsive to conventional therapy, including systemic antibiotics. A single course of therapy for 15 to 20 weeks has been shown to result in complete and prolonged remission of disease in many patients.

Pregnancy: Category X. Prescribers should be alert to the warning signs of psychiatric disorders to guide patients to receive the help they need. Therefore, prior to initiation of Amnesteem therapy, patients and family members should be asked about any history of psychiatric disorder, and at each visit during therapy patients should be assessed for symptoms of depression, mood disturbance, psychosis, or aggression to determine if further evaluation may be necessary.

Patients should stop Amnesteem and the patient or a family member should promptly contact their prescriber if the patient develops depression, mood disturbance, psychosis, or aggression, without waiting until the next visit. Discontinuation of Amnesteem therapy may be insufficient; further evaluation may be necessary. While such monitoring may be helpful, it may not detect all patients at risk.

Patients may report mental health problems or family history of psychiatric disorders. A referral to a mental health professional may be necessary. The physician should consider whether Amnesteem therapy is appropriate in this setting; for some patients the risks may outweigh the benefits of Amnesteem therapy.

Amnesteem use has been associated with a number of cases of pseudotumor cerebri benign intracranial hypertension , some of which involved concomitant use of tetracyclines. Concomitant treatment with tetracyclines should therefore be avoided. Early signs and symptoms of pseudotumor cerebri include papilledema, headache, nausea and vomiting, and visual disturbances.

There have been post-marketing reports of erythema multiforme and severe skin reactions [e. These events may be serious and result in death, life-threatening events, hospitalization, or disability. Patients should be monitored closely for severe skin reactions, and discontinuation of Amnesteem should be considered if warranted. Acute pancreatitis has been reported in patients with either elevated or normal serum triglyceride levels.

In rare instances, fatal hemorrhagic pancreatitis has been reported. Amnesteem should be stopped if hypertriglyceridemia cannot be controlled at an acceptable level or if symptoms of pancreatitis occur. In clinical trials, the effects on triglycerides, HDL, and cholesterol were reversible upon cessation of Amnesteem therapy. Some patients have been able to reverse triglyceride elevation by reduction in weight, restriction of dietary fat and alcohol, and reduction in dose while continuing Amnesteem.

Blood lipid determinations should be performed before Amnesteem is given and then at intervals until the lipid response to Amnesteem is established, which usually occurs within 4 weeks. Impaired hearing has been reported in patients taking Amnesteem; in some cases, the hearing impairment has been reported to persist after therapy has been discontinued.

Mechanism s and causality for this event have not been established. Clinical hepatitis considered to be possibly or probably related to Amnesteem therapy has been reported. If normalization does not readily occur or if hepatitis is suspected during treatment with Amnesteem, the drug should be discontinued and the etiology further investigated. Amnesteem has been associated with inflammatory bowel disease including regional ileitis in patients without a prior history of intestinal disorders.

In some instances, symptoms have been reported to persist after Amnesteem treatment has been stopped. Effects of multiple courses of Amnesteem on the developing musculoskeletal system are unknown. There is some evidence that long-term, high-dose, or multiple courses of therapy with isotretinoin have more of an effect than a single course of therapy on the musculoskeletal system.

Sixteen 7. Nine patients 4. Twenty-one Follow-up studies performed in eight of the patients with decreased bone mineral density for up to 11 months thereafter demonstrated increasing bone density in five patients at the lumbar spine, while the other three patients had lumbar spine bone density measurements below baseline values. Total hip bone mineral densities remained below baseline range —1.

In a separate open-label extension study of ten patients, ages 13 to 18 years, who started a second course of Amnesteem 4 months after the first course, two patients showed a decrease in mean lumbar spine bone mineral density up to 3. Spontaneous reports of osteoporosis, osteopenia, bone fractures, and delayed healing of bone fractures have been seen in the Amnesteem population.

While causality to Amnesteem has not been established, an effect cannot be ruled out. Longer term effects have not been studied. It is important that Amnesteem be given at the recommended doses for no longer than the recommended duration.

A high prevalence of skeletal hyperostosis was noted in clinical trials for disorders of keratinization with a mean dose of 2. Additionally, skeletal hyperostosis was noted in six of eight patients in a prospective study of disorders of keratinization. The skeletal effects of multiple Amnesteem treatment courses for acne are unknown. Hyperostosis may require a longer time frame to appear. The clinical course and significance remain unknown. There are spontaneous reports of premature epiphyseal closure in acne patients receiving recommended doses of Amnesteem.

The effect of multiple courses of Amnesteem on epiphyseal closure is unknown. Visual problems should be carefully monitored. Corneal opacities have occurred in patients receiving Amnesteem for acne and more frequently when higher drug dosages were used in patients with disorders of keratinization. Decreased night vision has been reported during Amnesteem therapy and in some instances the event has persisted after therapy was discontinued.

Because the onset in some patients was sudden, patients should be advised of this potential problem and warned to be cautious when driving or operating any vehicle at night. These include:. To prescribe isotretinoin, the prescriber must be enrolled and activated with the pregnancy risk management program iPLEDGE.

Prescribers can enroll by signing and returning the completed enrollment form. Prescribers can only activate their enrollment by affirming that they meet requirements and will comply with all iPLEDGE requirements by attesting to the following points:.

Isotretinoin must only be prescribed to patients who are known not to be pregnant as confirmed by a negative CLIA-certified laboratory conducted pregnancy test. Meeting the requirements for a patient who can become pregnant signifies that the patient:.

If the patient has unprotected sexual contact with a partner that could result in pregnancy at any time one month before, during, or one month after therapy, the patient must:.

Any birth control method can fail. These reports are more frequent for patients who use only a single form of contraception.

Therefore, it is critically important that patients who can become pregnant use two effective forms of contraception simultaneously. Patients must receive warnings about the importance of choosing one primary method and a secondary method of contraception and that the patient must be compliant in use as outlined in the Guide for Patients who can get Pregnant.

Using two forms of contraception simultaneously substantially reduces the chances that a patient will become pregnant over the risk of pregnancy with either form alone. Although hormonal contraceptives are highly effective, prescribers are advised to consult the package insert of any medication administered concomitantly with hormonal contraceptives, since some medications may decrease the effectiveness of these birth control products. Patients should be prospectively cautioned not to self-medicate with the herbal supplement St.

Pregnancies have been reported by users of combined hormonal contraceptives who also used some form of St. If a pregnancy does occur during Amnesteem treatment, Amnesteem must be discontinued immediately. The patient should be referred to an Obstetrician-Gynecologist experienced in reproductive toxicity for further evaluation and counseling. Isotretinoin is contraindicated in patients who are pregnant. To receive isotretinoin all patients must meet all of the following conditions:.

In addition to the requirements for all patients described above, patients who can become pregnant must meet the following conditions:. To dispense isotretinoin, pharmacies must be enrolled and activated with the pregnancy risk management program iPLEDGE. The Responsible Site Pharmacist must enroll the pharmacy by signing and returning the completed Pharmacy Enrollment Form.

After enrolling, the Responsible Site Pharmacist can only activate the pharmacy enrollment by affirming that they meet requirements and will comply with all iPLEDGE requirements by attesting to the following points:. An Amnesteem Medication Guide must be given to the patient each time Amnesteem is dispensed, as required by law. This Amnesteem Medication Guide is an important part of the risk management program for the patients.

Only FDA-approved Amnesteem products must be distributed, prescribed, dispensed, and used. Patients must obtain Amnesteem prescriptions only at U.

Although an effect of Amnesteem on bone loss is not established, physicians should use caution when prescribing Amnesteem to patients with a genetic predisposition for age related osteoporosis, a history of childhood osteoporosis conditions, osteomalacia, or other disorders of bone metabolism. Patients may be at increased risk when participating in sports with repetitive impact where the risks of spondylolisthesis with and without pars fractures and hip growth plate injuries in early and late adolescence are known.

While causality to Amnesteem has not been established, an effect must not be ruled out. Anaphylactic reactions and other allergic reactions have been reported. Cutaneous allergic reactions and serious cases of allergic vasculitis, often with purpura bruises and red patches of the extremities and extracutaneous involvement including renal have been reported. Severe allergic reaction necessitates discontinuation of therapy and appropriate medical management.

Pretreatment and follow-up blood lipids should be obtained under fasting conditions. After consumption of alcohol, at least 36 hours should elapse before these determinations are made. It is recommended that these tests be performed at weekly or biweekly intervals until the lipid response to Amnesteem is established. Since elevations of liver enzymes have been observed during clinical trials, and hepatitis has been reported, pretreatment and follow-up liver function tests should be performed at weekly or biweekly intervals until the response to Amnesteem has been established see WARNINGS: Hepatotoxicity.

Some patients receiving Amnesteem have experienced problems in the control of their blood sugar. In addition, new cases of diabetes have been diagnosed during Amnesteem therapy, although no causal relationship has been established.

Some patients undergoing vigorous physical activity while on Amnesteem therapy have experienced elevated CPK levels; however, the clinical significance is unknown. There have been rare post-marketing reports of rhabdomyolysis, some associated with strenuous physical activity. In these patients, approximately half of the CPK elevations returned to normal within 2 weeks and half returned to normal within 4 weeks. No cases of rhabdomyolysis were reported in this trial.

The incidence of adrenal medullary hyperplasia was also increased at the higher dosage in both sexes. The relatively high level of spontaneous pheochromocytomas occurring in the male Fischer rat makes it an equivocal model for study of this tumor; therefore, the relevance of this tumor to the human population is uncertain. The Ames test was conducted with isotretinoin in two laboratories. The results of the tests in one laboratory were negative while in the second laboratory a weakly positive response less than 1.

No dose-response effect was seen and all other strains were negative. Additionally, other tests designed to assess genotoxicity Chinese hamster cell assay, mouse micronucleus test, S. In general, there was microscopic evidence for appreciable depression of spermatogenesis but some sperm were observed in all testes examined and in no instance were completely atrophic tubules seen.

In studies of 66 men, 30 of whom were patients with nodular acne under treatment with oral isotretinoin, no significant changes were noted in the count or motility of spermatozoa in the ejaculate.

In a study of 50 men ages 17 to 32 years receiving Amnesteem therapy for nodular acne, no significant effects were seen on ejaculate volume, sperm count, total sperm motility, morphology or seminal plasma fructose. It is not known whether this drug is excreted in human milk. Because of the potential for adverse effects, nursing mothers should not receive Amnesteem. The use of Amnesteem in pediatric patients less than 12 years of age has not been studied. Clinical studies of isotretinoin did not include sufficient numbers of subjects aged 65 years and over to determine whether they respond differently from younger subjects.

The adverse reactions listed below reflect the experience from investigational studies of Amnesteem, and the post-marketing experience. The relationship of some of these events to Amnesteem therapy is unknown. Many of the side effects and adverse reactions seen in patients receiving Amnesteem are similar to those described in patients taking very high doses of vitamin A dryness of the skin and mucous membranes, e.

Cheilitis and hypertriglyceridemia are usually dose related. Cardiovascular: palpitation, tachycardia, vascular thrombotic disease, stroke. Neurological: pseudotumor cerebri see WARNINGS: Pseudotumor Cerebri , dizziness, drowsiness, headache, insomnia, lethargy, malaise, nervousness, paresthesias, seizures, stroke, syncope, weakness.

Of the patients reporting depression, some reported that the depression subsided with discontinuation of therapy and recurred with reinstitution of therapy. Respiratory: bronchospasms with or without a history of asthma , respiratory infection, voice alteration. In humans, overdosage has been associated with vomiting, facial flushing, cheilosis, abdominal pain, headache, dizziness, and ataxia. These symptoms quickly resolve without apparent residual effects.

Patients who can become pregnant who present with isotretinoin overdose must be evaluated for pregnancy. Educational materials for such patients can be obtained by calling the manufacturer.

Because an overdose would be expected to result in higher levels of isotretinoin in semen than found during a normal treatment course, male patients should use a condom, or avoid reproductive sexual activity with a patient who is or might become pregnant, for one month after the overdose. All patients with isotretinoin overdose should not donate blood for at least one month.

The recommended dosage range for Amnesteem is 0. In studies comparing 0. Failure to take Amnesteem with food will significantly decrease absorption.

Before upward dose adjustments are made, the patients should be questioned about their compliance with food instructions. The safety of once daily dosing with Amnesteem has not been established. Once daily dosing is not recommended. After a period of 2 months or more off therapy, and if warranted by persistent or recurring severe nodular acne, a second course of therapy may be initiated. The optimal interval before retreatment has not been defined for patients who have not completed skeletal growth.

Long-term use of Amnesteem, even in low doses, has not been studied, and is not recommended. Amnesteem must only be dispensed in no more than a day supply. This Amnesteem Medication Guide is an important part of the risk management program for the patient. The 20 mg capsules are reddish brown and cream and imprinted with I They are available as follows:.

I have asked the patient if there are any questions regarding treatment with isotretinoin and have answered those questions to the best of my ability.

To be completed by patient and parent or guardian if patient is under age 18 and signed by the doctor. A parent or guardian of a patient under age 18 must also read and understand each item before signing the agreement. Do not sign this agreement and do not take isotretinoin if there is anything that you do not understand about all the information you have received about using isotretinoin. Read the Medication Guide that comes with Amnesteem before you start taking it and each time you get a prescription.

There may be new information. This information does not take the place of talking with your doctor about your medical condition or your treatment. After stopping Amnesteem, you may also need follow-up mental health care if you had any of these symptoms. Amnesteem is a medicine taken by mouth to treat the most severe form of acne nodular acne that cannot be cleared up by any other acne treatments, including antibiotics.

Amnesteem can only be:. Severe nodular acne is when many red, swollen, tender lumps form in the skin. These can be the size of pencil erasers or larger. If untreated, nodular acne can lead to permanent scars. Tell your doctor if you or a family member has any of the following health conditions:. Tell your doctor if you are pregnant or breast-feeding. Amnesteem must not be used by patients who are pregnant or breast-feeding.

Tell your doctor about all of the medicines you take including prescription and non-prescription medicines, vitamins and herbal supplements.

Amnesteem and certain other medicines can interact with each other, sometimes causing serious side effects. Especially tell your doctor if you take:. These medicines should not be used with Amnesteem unless your doctor tells you it is okay.

Know the medicines you take. Keep a list of them to show to your doctor and pharmacist. Do not take any new medicine without talking with your doctor. You must talk about effective birth control forms with your doctor or go for a free visit to talk about birth control with another doctor or family planning expert. Your doctor can arrange this free visit, which will be paid for by the company that makes Amnesteem.

If you have sex at any time without using two forms of effective birth control, get pregnant, or miss your expected period, stop using Amnesteem and call your doctor right away. These are not all of the possible side effects with Amnesteem. Your doctor or pharmacist can give you more detailed information. Call your doctor for medical advice about side effects. Medicines are sometimes prescribed for conditions that are not mentioned in Medication Guides.

Do not use Amnesteem for a condition for which it was not prescribed. Do not give Amnesteem to other people, even if they have the same symptoms that you have. It may harm them. This Medication Guide summarizes the most important information about Amnesteem. If you would like more information, talk with your doctor. You can ask your doctor or pharmacist for information about Amnesteem that is written for healthcare professionals.

If you are a consumer or patient please visit this version. Amnesteem must not be used by patients who are or may become pregnant. There is an extremely high risk that life threatening birth defects will result if pregnancy occurs while taking Amnesteem in any amount, even for short periods of time.

Potentially any fetus exposed during pregnancy can be affected. There are no accurate means of determining whether an exposed fetus has been affected. Birth defects which have been documented following Amnesteem exposure include abnormalities of the face, eyes, ears, skull, central nervous system, cardiovascular system, and thymus and parathyroid glands.

Cases of IQ scores less than 85 with or without other abnormalities have been reported. There is an increased risk of spontaneous abortion, and premature births have been reported. Documented external abnormalities include: skull abnormality; ear abnormalities including anotia, micropinna, small or absent external auditory canals ; eye abnormalities including microphthalmia ; facial dysmorphia; cleft palate.

Documented internal abnormalities include: CNS abnormalities including cerebral abnormalities, cerebellar malformation, hydrocephalus, microcephaly, cranial nerve deficit ; cardiovascular abnormalities; thymus gland abnormality; parathyroid hormone deficiency. In some cases death has occurred with certain of the abnormalities previously noted. If pregnancy does occur during treatment of a patient who is taking Amnesteem, Amnesteem must be discontinued immediately and the patient should be referred to an Obstetrician-Gynecologist experienced in reproductive toxicity for further evaluation and counseling.

Isotretinoin, USP a retinoid, is available as Amnesteem isotretinoin capsules, USP in 10 mg, 20 mg and 40 mg soft gelatin capsules for oral administration. Each capsule contains butylated hydroxyanisole, edetate disodium, gelatin, glycerin, hydrogenated vegetable oil, soybean oil and yellow wax. The 10 mg capsules also contain red iron oxide paste and the 20 mg and 40 mg capsules also contain red iron oxide paste, titanium dioxide and yellow iron oxide paste.

The black imprinting ink contains ammonium hydroxide, black iron oxide, polyethylene glycol, propylene glycol and polyvinyl acetate phthalate. Chemically, isotretinoin is cis -retinoic acid and is related to both retinoic acid and retinol vitamin A. It is a yellow to orange crystalline powder with a molecular weight of The structural formula is:. Isotretinoin is a retinoid, which when administered in pharmacologic dosages of 0. The exact mechanism of action of isotretinoin is unknown.

Clinical improvement in nodular acne patients occurs in association with a reduction in sebum secretion. The decrease in sebum secretion is temporary and is related to the dose and duration of treatment with Amnesteem, and reflects a reduction in sebaceous gland size and an inhibition of sebaceous gland differentiation. Due to its high lipophilicity, oral absorption of isotretinoin is enhanced when given with a high-fat meal. In a crossover study, 74 healthy adult subjects received a single 80 mg oral dose 2 x 40 mg capsules of Amnesteem under fasted and fed conditions.

Both peak plasma concentration C max and the total exposure AUC of isotretinoin were more than doubled following a standardized high-fat meal when compared with Amnesteem given under fasted conditions see Table 2. The observed elimination half-life was unchanged. This lack of change in half-life suggests that food increases the bioavailability of isotretinoin without altering its disposition. The time to peak concentration T max was also increased with food and may be related to a longer absorption phase.

Clinical studies have shown that there is no difference in the pharmacokinetics of isotretinoin between patients with nodular acne and healthy subjects with normal skin.

Following oral administration of isotretinoin, at least three metabolites have been identified in human plasma: 4- oxo -isotretinoin, retinoic acid tretinoinand 4- oxo -retinoic acid 4- oxo -tretinoin.

Retinoic acid and cis -retinoic acid are geometric isomers and show reversible interconversion. The administration of one isomer will give rise to the other. Isotretinoin is also irreversibly oxidized to 4- oxo -isotretinoin, which forms its geometric isomer 4- oxo -tretinoin.

After a single 80 mg oral dose of Amnesteem to 74 healthy adult subjects, concurrent administration of food increased the extent of formation of all metabolites in plasma when compared to the extent of formation under fasted conditions.

All of these metabolites possess retinoid activity that is in some in vitro models more than that of the parent isotretinoin. However, the clinical significance of these models is unknown. In vitro studies indicate that the primary P isoforms involved in isotretinoin metabolism are 2C8, 2C9, 3A4, and 2B6.

Isotretinoin and its metabolites are further metabolized into conjugates, which are then excreted in urine and feces. Following oral administration of an 80 mg dose of 14 C-isotretinoin as a liquid suspension, 14 C-activity in blood declined with a half-life of 90 hours. After both single and multiple doses, the observed accumulation ratios of isotretinoin ranged from 0. In both age groups, 4- oxo -isotretinoin was the major metabolite; tretinoin and 4- oxo -tretinoin were also observed.

The dose-normalized pharmacokinetic parameters for isotretinoin following single and multiple doses are summarized in Table 3 for pediatric patients. There were no statistically significant differences in the pharmacokinetics of isotretinoin between pediatric and adult patients.

The accumulation ratios of isotretinoin ranged from 0. Amnesteem is indicated for the treatment of severe recalcitrant nodular acne. Nodules are inflammatory lesions with a diameter of 5 mm or greater. The nodules may become suppurative or hemorrhagic. Because of significant adverse effects associated with its use, Amnesteem should be reserved for patients with severe nodular acne who are unresponsive to conventional therapy, including systemic antibiotics.

A single course of therapy for 15 to 20 weeks has been shown to result in complete and prolonged remission of disease in many patients. Pregnancy: Category X. Prescribers should be alert to the warning signs of psychiatric disorders to guide patients to receive the help they need. Therefore, prior to initiation of Amnesteem therapy, patients and family members should be asked about any history of psychiatric disorder, and at each visit during therapy patients should be assessed for symptoms of depression, mood disturbance, psychosis, or aggression to determine if further evaluation may be necessary.

Patients should stop Amnesteem and the patient or a family member should promptly contact their prescriber if the patient develops depression, mood disturbance, psychosis, or aggression, without waiting until the next visit. Discontinuation of Amnesteem therapy may be insufficient; further evaluation may be necessary. While such monitoring may be helpful, it may not detect all patients at risk. Patients may report mental health problems or family history of psychiatric disorders.

A referral to a mental health professional may be necessary. The physician should consider whether Amnesteem therapy is appropriate in this setting; for some patients the risks may outweigh the benefits of Amnesteem therapy. Amnesteem use has been associated with a number of cases of pseudotumor cerebri benign intracranial hypertensionsome of which involved concomitant use of tetracyclines. Concomitant treatment with tetracyclines should therefore be avoided.

Early signs and symptoms of pseudotumor cerebri include papilledema, headache, nausea and vomiting, and visual disturbances. There have been post-marketing reports of erythema multiforme and severe skin reactions [e. These events may be serious and result in death, life-threatening events, hospitalization, or disability.

Patients should be monitored closely for severe skin reactions, and discontinuation of Amnesteem should be considered if warranted. Acute pancreatitis has been reported in patients with either elevated or normal serum triglyceride levels.

In rare instances, fatal hemorrhagic pancreatitis has been reported. Amnesteem should be stopped if hypertriglyceridemia cannot be controlled at an acceptable level or if symptoms of pancreatitis occur. In clinical trials, the effects on triglycerides, HDL, and cholesterol were reversible upon cessation of Amnesteem therapy. Some patients have been able to reverse triglyceride elevation by reduction in weight, restriction of dietary fat and alcohol, and reduction in dose while continuing Amnesteem.

Blood lipid determinations should be performed before Amnesteem is given and then at intervals until the lipid response to Amnesteem is established, which usually occurs within 4 weeks. Impaired hearing has been reported in patients taking Amnesteem; in some cases, the hearing impairment has been reported to persist after therapy has been discontinued. Mechanism s and causality for this event have not been established.

Clinical hepatitis considered to be possibly or probably related to Amnesteem therapy has been reported. If normalization does not readily occur or if hepatitis is suspected during treatment with Amnesteem, the drug should be discontinued and the etiology further investigated.

Amnesteem has been associated with inflammatory bowel disease including regional ileitis in patients without a prior history of intestinal disorders. In some instances, symptoms have been reported to persist after Amnesteem treatment has been stopped.

Effects of multiple courses of Amnesteem on the developing musculoskeletal system are unknown. There is some evidence that long-term, high-dose, or multiple courses of therapy with isotretinoin have more of an effect than a single course of therapy on the musculoskeletal system.

Sixteen 7. Nine patients 4. Twenty-one Follow-up studies performed in eight of the patients with decreased bone mineral density for up to 11 months thereafter demonstrated increasing bone density in five patients at the lumbar spine, while the other three patients had lumbar spine bone density measurements below baseline values.

Total hip bone mineral densities remained below baseline range —1. In a separate open-label extension study of ten patients, ages 13 to 18 years, who started a second course of Amnesteem 4 months after the first course, two patients showed a decrease in mean lumbar spine bone mineral density up to 3.

Spontaneous reports of osteoporosis, osteopenia, bone fractures, and delayed healing of bone fractures have been seen in the Amnesteem population. While causality to Amnesteem has not been established, an effect cannot be ruled out.

Longer term effects have not been studied. It is important that Amnesteem be given at the recommended doses for no longer than the recommended duration. A high prevalence of skeletal hyperostosis was noted in clinical trials for disorders of keratinization with a mean dose of 2.

Additionally, skeletal hyperostosis was noted in six of eight patients in a prospective study of disorders of keratinization. The skeletal effects of multiple Amnesteem treatment courses for acne are unknown.

Hyperostosis may require a longer time frame to appear. The clinical course and significance remain unknown. There are spontaneous reports of premature epiphyseal closure in acne patients receiving recommended doses of Amnesteem. The effect of multiple courses of Amnesteem on epiphyseal closure is unknown. Visual problems should be carefully monitored. Corneal opacities have occurred in patients receiving Amnesteem for acne and more frequently when higher drug dosages were used in patients with disorders of keratinization.

Decreased night vision has been reported during Amnesteem therapy and in some instances the event has persisted after therapy was discontinued.

Accutane (isotretinoin) and Amnesteem (isotretinoin) are forms of vitamin A called retinoids used for the treatment and prevention of severe acne. Amnesteem is a prescription medicine used to treat the symptoms of Severe, Recalcitrant Nodular Acne. Amnesteem may be used alone or with other. Compare prices and print coupons for Amnesteem (Generic Accutane) and other drugs at CVS, Walgreens, and other pharmacies.

Birth defects deformed babiesloss of a baby before birth miscarriagedeath of the baby, and early premature births. Although an effect of Amnesteem on bone loss is not established, physicians should use caution when prescribing Amnesteem to patients with a genetic predisposition for age related osteoporosis, a history of childhood osteoporosis conditions, osteomalacia, or other disorders of bone metabolism.

Drug information provided by: IBM Micromedex. Isotretinoin is used to treat severe, disfiguring nodular acne. It should be used only after other acne medicines or antibiotics have been tried and have failed to help the acne. Isotretinoin may also be used to treat other skin diseases as determined by your doctor. Isotretinoin must not be used to treat women who are able to bear children unless other forms of treatment have been tried first and have failed.

Isotretinoin must not be taken during pregnancy because it causes birth defects in humans. If you are able to bear children, it is very important that you read, understand, and follow the pregnancy warnings for isotretinoin. There is a problem with information submitted for this request.
