              Pregnancy & Lactation

              Preganacy

              Therapy is contraindicated during pregnancy; it can cause fetal harm when administered to a pregnant patient; there is increased risk of major congenital malformations, spontaneous abortions, and premature births following isotretinoin exposure during pregnancy in humans

              If drug is used during pregnancy, or if patient becomes pregnant while receiving therapy, patient should be apprised of potential hazard to a fetus

              If pregnancy occurs during treatment of patient receiving therapy, it must be discontinued immediately and patient should be referred to Obstetrician-Gynecologist experienced in reproductive toxicity for further evaluation and counseling

              If a pregnancy occurs during treatment, discontinue therapy immediately and refer patient to obstetrician/gynecologist experienced in reproductive toxicity for further evaluation and counseling; any suspected fetal exposure during or 1 month after initiating therapy must be reported immediately to the FDA via MedWatch telephone number 1-800-FDA-1088, and also to the iPLEDGE pregnancy registry at 1-866-495-0654 or via the internet (www.ipledgeprogram.com)

              Contraception

              • Patients who can become pregnant must use 2 forms of contraception simultaneously, at least 1 of which must be a primary form, for at least 1 month prior to initiation of therapy, during therapy, and for 1 month after discontinuing therapy; however, 2 forms of contraception is not required if the patient commits to continuous abstinence from not having any sexual contact with a partner which may result in pregnancy, has undergone a hysterectomy or bilateral oophorectomy, or has been medically confirmed to be post- menopausal
              • Micro-dosed progesterone preparations (“minipills” that do not contain an estrogen) are an inadequate method of contraception during therapy.
              • Any birth control method can fail; there have been reports of pregnancy from patients who have used combination oral contraceptives, as well as contraceptive vaginal systems, vaginal inserts, transdermal systems, and injections; these pregnancies occurred while taking isotretinoin
              • It is critically important that patients who can become pregnant use 2 methods of contraception simultaneously
              • A clinical drug interaction study did not show any clinically significant interaction between isotretinoin and norethindrone and ethinyl estradiol; however, it is not known if there is an interaction between isotretinoin with other progestins
              • Prescribers are advised to consult the prescribing information of any medication administered concomitantly with hormonal contraceptives, since some medications may decrease effectiveness of these birth control products
              • Patients who can become pregnant should be prospectively cautioned not to self-medicate with herbal supplement St. John’s Wort because of a possible interaction with hormonal contraceptives based on reports of breakthrough bleeding on oral contraceptives shortly after starting St. John’s Wort; pregnancies have been reported by users of combined hormonal contraceptives who also used some form of St. John’s Wort
              • If patient has unprotected sexual contact with a partner that could result in pregnancy at any time 1 month before, during, or 1 month after therapy, the patient must: Stop taking therapy immediately
              • If had unprotected sexual contact and on therapy
                • Have a pregnancy test at least 19 days after the last act of unprotected sexual contact with a partner that could result in pregnancy
                • Start using 2 forms of contraception simultaneously again for 1 month before resuming therapy
                • Have a second pregnancy test after using 2 forms of contraception for 1 month

              Reproductive Potential

              • Must only be prescribed to patients who are known not to be pregnant as confirmed by a negative CLIA-certified laboratory conducted pregnancy test; patients who can become pregnant must have had two negative urine or serum pregnancy tests with a sensitivity of at least 25 mIU/mL before receiving the initial therapy (the interval between the two tests must be at least 19 days)
              • The first test (a screening test) is obtained by the prescriber when the decision is made to prescribe therapy

              Therapy is available only through a restricted program under a REMS called the iPLEDGE REMS because of the risk of embryo-fetal toxicity

              Under REMS, prescribers must be certified with the program and comply with the following requirements

              Lactation

              There are no data on either animal or human milk, effects on breastfed infant, or on milk production; because of potential for serious adverse reactions in nursing infants from isotretinoin, advise patients that breastfeeding is not recommended during treatment and for at least 8 days after the last dose

              Pregnancy Categories

              A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.

              B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.

              C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.

              D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.

              X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.

              NA: Information not available.

              AUC

              • 10,004 ng•hr/mL (fed): 3703 ng•hr/mL (fasted)
              • Absorica: 6095 ng•hr/mL (fed); 4055 ng•hr/mL (fasted); AUC (fasted state) greater than Accutane, and therefore not interchangeable with generic products
              • Absorica LD: 10,209 ng•hr/mL; ∼20% lower under fasting conditions

              Distribution

              Protein bound: 99.9% (primarily albumin)

              Metabolism

              Metabolized by liver oxidation via hepatic isoenzymes CYP2B6, CYP2C8/9, and CYP3A4

              Metabolites: 4-oxo-isotretinoin, retinoic acid (tretinoin), 4-oxo-retinoic acid

              Elimination

              Half-life: 18 hr (Absorica); 24 hr (Absorica LD); 38 hr (4-oxo-isotretinoin metabolite)

              Excretion: 65-83% of drug excreted in feces and urine in relatively equal amounts

              ISOTRETINOIN - ORAL

              (EYE-soeTRET-i-noyn)

              COMMON BRAND NAME(S): Absorica, Absorica LD, Accutane, Amnesteem, Claravis, Sotret

              WARNING: Women who are pregnant must not use isotretinoin. Women must avoid becoming pregnant while taking this medication. Serious (sometimes fatal) birth defects, miscarriages, and premature births have occurred when this drug has been used during pregnancy.For female patients, two effective forms of birth control (or complete avoidance of sexual intercourse) must be used for 1 month before starting isotretinoin, during use, and for 1 month after stopping this drug. You must also have monthly pregnancy-avoidance counseling from your doctor. Do not use "minipills" for birth control (non-estrogen-containing pills) since they may not work as well with isotretinoin. If you are late in having your period, or if you have sexual intercourse at any time without using two effective forms of birth control, stop taking this medication and contact your doctor right away. (See also the Precautions section.)Only patients enrolled in the iPLEDGE program may obtain and use isotretinoin. You will need to register with iPLEDGE and view a video at your doctor's office before receiving your prescription. Only physicians enrolled in iPLEDGE may prescribe isotretinoin, and only pharmacies enrolled in the program may dispense it. Consult your doctor or pharmacist for more details about the iPLEDGE program and for more information about the risks and benefits of using this medication.For female patients who are able to become pregnant (even if not sexually active), you will need to contact iPLEDGE every month, either through the internet or by telephone, and answer required questions every time you fill your prescription and 1 month after your last dose.These requirements apply in the United States. If you live in Canada or any other country, consult your doctor and pharmacist for your specific regulations.

              USES: This medication is used to treat severe cystic acne (also known as nodular acne) that has not responded to other treatment (e.g., benzoyl peroxide or clindamycin applied to the skin or tetracycline or minocycline taken by mouth). It belongs to a class of drugs known as retinoids. It works by decreasing facial oil (sebum) production. High amounts of sebum can lead to severe acne. If left untreated, severe acne may cause permanent scarring.

              HOW TO USE: Read the Medication Guide provided by your pharmacist before you start using isotretinoin and each time you get a refill. Read and sign a Patient Information/Informed Consent form before you start taking this medication. If you have any questions about isotretinoin, consult your doctor or pharmacist before taking the medication.Swallow capsules whole. Do not crush or chew them. Isotretinoin is usually taken twice daily for 15-20 weeks, or as directed by your doctor. Directions for most generic forms of isotretinoin state that it should be taken with meals. However, the FDA has indicated that the Absorica brand may be taken with or without food. Food helps increase absorption of this drug into your bloodstream. Ask your doctor or pharmacist for more information. Take this drug with a full glass of water, and do not lie down for at least 10 minutes after taking it.The dosage is based on your medical condition, weight, and response to treatment.Your acne may worsen during the first few days of taking this drug, and it may take up to 1-2 months before you notice the full benefit of this medication. If severe acne returns, a second course of treatment may be started after you have stopped taking the drug for 2 months. The manufacturer does not recommend long-term use of isotretinoin. Do not take more than the recommended dose.Since this drug can be absorbed through the skin and lungs and may harm an unborn baby, women who are pregnant or who may become pregnant should not handle this medication or breathe the dust from the capsules.

              SIDE EFFECTS: Dry lips and mouth, minor swelling of the eyelids or lips, crusty skin, nosebleeds, upset stomach, or thinning of hair may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.To relieve dry mouth, suck on (sugarless) hard candy or ice chips, chew (sugarless) gum, drink water, or use a saliva substitute.Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.Tell your doctor right away if you have any serious side effects, including: mental/mood changes (such as depression, anxiety, thoughts of suicide), tingling feeling in the skin, back/joint/muscle pain, signs of infection (e.g., fever, persistent sore throat), painful swallowing, peeling skin on palms/soles.Isotretinoin may rarely cause disease of the pancreas (pancreatitis) that may rarely be fatal. Stop taking this medication and tell your doctor right away if you develop: severe stomach pain, severe or persistent nausea/vomiting.Stop taking this medication and tell your doctor right away if you develop these unlikely but very serious side effects: severe headache, vision changes, ringing in the ears, hearing loss, chest pain, yellowing eyes/skin, dark urine, severe diarrhea, rectal bleeding.A very serious allergic reaction to this drug is rare. However, seek immediate medical attention if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.In the US -Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088 or at www.fda.gov/medwatch.In Canada - Call your doctor for medical advice about side effects. You may report side effects to Health Canada at 1-866-234-2345.

              PRECAUTIONS: Before taking isotretinoin, tell your doctor or pharmacist if you are allergic to it; or to vitamin A-related drugs (other retinoids such as tretinoin); or if you have any other allergies. This product may contain inactive ingredients (such as soybean, parabens), which can cause allergic reactions or other problems. Some people who are allergic to peanuts may also be allergic to soy.

Contact your doctor for more information.Do not have cosmetic procedures to smooth your skin (e.g., waxing, laser, dermabrasion) during and for 6 months after isotretinoin therapy. Skin scarring may occur.Avoid the use of alcohol while taking this medication because it may increase the risk of certain side effects (e.g., pancreatitis).Limited information suggests isotretinoin may cause some bone loss effects. Playing contact or repetitive impact sports (e.g., football, basketball, soccer, tennis) may result in bone problems, including an increased risk of broken bones. Limited information also suggests isotretinoin may stop normal growth in some children (epiphyseal plate closure). Consult your doctor for more details.Caution is advised when using this drug in the elderly because they may be more sensitive to its effects, especially the effects on bones.Caution is advised when using this drug in children because they may be more sensitive to its effects, especially back/joint/muscle pain.This drug must not be used during pregnancy or by those who may become pregnant during treatment. If you become pregnant or think you may be pregnant, inform your doctor right away. See also Warning section.Since this drug can be absorbed through the skin and lungs and may harm an unborn baby, women who are pregnant or who may become pregnant should not handle this medication or breathe the dust from the capsules.You must have two negative pregnancy tests before starting this medication. You must have a monthly pregnancy test during treatment with isotretinoin. If the test is positive, you must stop taking this medication and consult your doctor right away.It is unknown if this medication passes into breast milk.
