If you are a consumer or patient please visit this version. There is an extremely high risk that severe birth defects will result if pregnancy occurs while taking Accutane 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 Accu tane 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 Accu tane , Accu tane must be discontinued immediately and the patient should be referred to an Obstetrician-Gynecologist experienced in reproductive toxicity for further evaluation and counseling.
Because of Accutane's teratogenicity and to minimize fetal exposure, Accutane is approved for marketing only under a special restricted distribution program approved by the Food and Drug Administration. Isotretinoin USP, a retinoid, is available as Accutane isotretinoin capsules, USP in 10 mg, 20 mg, 30 mg and 40 mg soft gelatin capsules for oral administration.
Each capsule contains butylatedhydroxyanisole, edetate disodium, hydrogenated vegetable oil Type-I and Type-II , medium chain triglyceride, refined soybean oil and white wax. Chemically, isotretinoin is cis-retinoic acid and is related to both retinoic acid and retinol vitamin A.
It is a yellow to slightly 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 Accutane, 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 Accutane 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 Accutane 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-oxotretinoin.
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 Accutane 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. Table 3. The accumulation ratios of isotretinoin ranged from 0. Accutane 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, Accutane 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. Accutane should not be given to patients who are sensitive to parabens, which are used as preservatives in the gelatin capsule.
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 Accutane 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 Accutane 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 Accutane 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 Accutane therapy is appropriate in this setting; for some patients the risks may outweigh the benefits of Accutane therapy.
Accutane 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 Accutane 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. Accutane 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 Accutane 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 Accutane 5. Blood lipid determinations should be performed before Accutane is given and then at intervals until the lipid response to Accutane is established, which usually occurs within 4 weeks. Impaired hearing has been reported in patients taking Accutane; 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 Accutane therapy has been reported.
If normalization does not readily occur or if hepatitis is suspected during treatment with Accutane, the drug should be discontinued and the etiology further investigated. Accutane 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 Accutane treatment has been stopped. Effects of multiple courses of Accutane 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 Accutane 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 Accutane population. While causality to Accutane has not been established, an effect cannot be ruled out. Longer term effects have not been studied. It is important that Accutane 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 Accutane 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 Accutane. The effect of multiple courses of Accutane on epiphyseal closure is unknown. Visual problems should be carefully monitored. Corneal opacities have occurred in patients receiving Accutane for acne and more frequently when higher drug dosages were used in patients with disorders of keratinization. Decreased night vision has been reported during Accutane therapy and in some instances the event has persisted after therapy was discontinued.

I know the risk factors for unplanned pregnancy and the effective measures for avoidance of unplanned pregnancy. I have the expertise to provide the patient with detailed pregnancy prevention counseling, or I will refer the patient to an expert for such counseling, reimbursed by the manufacturer.
Before beginning treatment of patients who can become pregnant with isotretinoin, and on a monthly basis, the patient will be counseled to avoid pregnancy by using two forms of contraception simultaneously and continuously for at least one month prior to initiation of isotretinoin treatment, during isotretinoin treatment and for one month after discontinuing isotretinoin treatment, unless the patient commits to continuous abstinence, not having any sexual contact with a partner that could result in pregnancy.
I will not prescribe isotretinoin to any patient who can become pregnant until verifying the patient has a negative screening pregnancy test and monthly negative CLIA-certified Clinical Laboratory Improvement Amendment pregnancy tests.
Patients should have a pregnancy test at the completion of the entire course of isotretinoin and another pregnancy test one month later. I will report any pregnancy case that I become aware of while the patient who can become pregnant is on isotretinoin or one month after the last dose to the pregnancy registry.
Enter monthly result from CLIA-certified laboratory conducted pregnancy test. 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 interval between the two tests should be at least 19 days. Has had a negative result from a urine or serum pregnancy test in a CLIA-certified laboratory before receiving each subsequent course of isotretinoin. A pregnancy test must be repeated every month, in a CLIA-certified laboratory, prior to the patient who can become pregnant receiving each prescription. Has selected and has committed to use two forms of effective contraception simultaneously, at least one of which must be a primary method, unless the patient commits to continuous abstinence not having any sexual contact with a partner that could result in pregnancy, or the patient has undergone a hysterectomy or bilateral oophorectomy, or has been medically confirmed to be post-menopausal.
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 Accu tane immediately , if on therapy 2. Start using two forms of effective contraception simultaneously again for one month before resuming Accutane therapy 4. General Although an effect of Accutane on bone loss is not established, physicians should use caution when prescribing Accutane to patients with a genetic predisposition for age-related osteoporosis, a history of childhood osteoporosis conditions, osteomalacia, or other disorders of bone metabolism.
Patients must be instructed to read the Medication Guide supplied as required by law when Accutane is dispensed. The complete text of the Medication Guide is reprinted at the end of this document. Patients who can become pregnant must be instructed that they must not be pregnant when Accutane therapy is initiated, and that they should use two forms of effective contraception simultaneously for one month before starting Accutane, while taking Accutane, and for one month after Accutane has been stopped, unless they commit to continuous abstinence from not having any sexual contact with a partner that could result in pregnancy.
They should be given an opportunity to view the patient video provided by the manufacturer to the prescriber. The video includes information about contraception, the most common reasons that contraception fails, and the importance of using two forms of effective contraception when taking teratogenic drugs and comprehensive information about types of potential birth defects which could occur if a patient who is pregnant takes Accutane at any time during pregnancy.
Accutane is found in the semen of male patients taking Accutane, but the amount delivered to a a patient who can become pregnant would be about 1 million times lower than an oral dose of 40 mg. While the no-effect limit for isotretinoin induced embryopathy is unknown, 20 years of postmarketing 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 Accutane 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 Accutane treatment may be insufficient; further evaluation may be necessary.
Patients must be informed that some patients, while taking Accutane or soon after stopping Accutane, have become depressed or developed other serious mental problems. Some patients taking Accutane have had thoughts about hurting themselves or putting an end to their own lives suicidal thoughts. There have been reports of patients on Accutane 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 Accutane. Some people have had other signs of depression while taking Accutane. Patients must be informed that they must not share Accutane with anyone else because of the risk of birth defects and other serious adverse events.
Patients must be informed not to donate blood during therapy and for one month following discontinuation of the drug because the blood might be given to a pregnant patient whose fetus must not be exposed to Accutane. To decrease the risk of esophageal irritation, patients should swallow the capsules with a full glass of liquid. Patients should be informed that transient exacerbation flare of acne has been seen, generally during the initial period of therapy.
Patients should be advised to avoid prolonged exposure to UV rays or sunlight. Patients should be informed that they may experience decreased tolerance to contact lenses during and after therapy. 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 Accutane. Consideration should be given to discontinuation of Accutane if any significant abnormality is found.
Neutropenia and rare cases of agranulocytosis have been reported. Accutane should be discontinued if clinically significant decreases in white cell counts occur. Patients should be advised that severe skin reactions Stevens-Johnson syndrome and toxic epidermal necrolysis have been reported in post-marketing data. Accutane should be discontinued if clinically significant skin reactions occur.
Hypersensitivity Anaphylactic reactions and other allergic reactions have been reported. Drug Interactions Drug Interactions Vitamin A: Because of the relationship of Accutane to vitamin A, patients should be advised against taking vitamin supplements containing vitamin A to avoid additive toxic effects.
Tetracyclines: Concomitant treatment with Accutane and tetracyclines should be avoided because Accutane use has been associated with a number of cases of pseudotumor cerebri benign intracranial hypertension , some of which involved concomitant use of tetracyclines.
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 Accutane.
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. Phenytoin: Accutane has not been shown to alter the pharmacokinetics of phenytoin in a study in seven healthy volunteers.
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 Accutane. Therefore, caution should be exercised when using these drugs together. Systemic Corticosteroids: Systemic corticosteroids are known to cause osteoporosis.
No formal clinical studies have been conducted to assess if there is an interactive effect on bone loss between systemic corticosteroids and Accutane. Lipids: 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 Accutane is established.
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 Accutane has been established see WARNINGS : Hepatotoxicity. Glucose: Some patients receiving Accutane have experienced problems in the control of their blood sugar.
In addition, new cases of diabetes have been diagnosed during Accutane therapy, although no causal relationship has been established. CPK: Some patients undergoing vigorous physical activity while on Accutane therapy have experienced elevated CPK levels; however, the clinical significance is unknown. There have been rare postmarketing 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. Nursing Mothers It is not known whether this drug is excreted in human milk. Pediatric Use The use of Accutane 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 Postmarketing Surveillance The adverse reactions listed below reflect the experience from investigational studies of Accutane, and the postmarketing experience. Dose Relationship Cheilitis and hypertriglyceridemia are usually dose related. Reproductive System abnormal menses. Accutane must only be dispensed in no more than a 30 day supply. This Accutane Medication Guide is an important part of the risk management program for the patient.
