Isotretinoin

Vitamin A: avoid concomitant use (7.1) Tetracyclines: avoid concomitant use (7.2)

7.1 Vitamin A Avoid concomitant use of ABSORICA/ABSORICA LD with supplements containing vitamin A. ABSORICA/ABSORICA LD is closely related to vitamin A. Therefore, concomitant use of ABSORICA/ABSORICA LD with vitamin A may lead to ABSORICA/ABSORICA LD-associated adverse reactions.

7.2 Tetracyclines Avoid concomitant use of ABSORICA/ABSORICA LD with tetracyclines because isotretinoin use has been associated with a number of cases of intracranial hypertension ( pseudotumor cerebri) , some of which involved concomitant use of tetracyclines [see Warnings and Precautions (5.5) ] .

7.3 Oral Contraceptives Isotretinoin Capsules did not result in clinically significant changes in the pharmacokinetics of norethindrone and ethinyl estradiol when used concomitantly with a norethindrone and ethinyl estradiol oral contraceptive [see Clinical Pharmacology ( 12.3 )]. It is not known if there is an interaction with the concomitant use of ABSORICA/ABSORICA LD with other oral contraceptives.

8.1 Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that documents pregnancies in patients exposed to isotretinoin during pregnancy. Report any suspected fetal exposure during or 1 month after ABSORICA/ABSORICA LD treatment immediately to the FDA via the 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) . Risk Summary ABSORICA/ABSORICA LD are contraindicated during pregnancy because isotretinoin can cause fetal harm when administered to a pregnant patient.

There is an increased risk of major congenital malformations, spontaneous abortions, and premature births following isotretinoin exposure during pregnancy in humans. If ABSORICA/ABSORICA LD is used during pregnancy, or if the patient becomes pregnant while taking ABSORICA/ABSORICA LD, apprise the patient of the potential hazard to a fetus. If pregnancy occurs during treatment of a patient who is taking ABSORICA/ABSORICA LD, immediately discontinue ABSORICA/ABSORICA LD and refer the patient to an Obstetrician-Gynecologist experienced in reproductive toxicity for further evaluation and counseling.

Data Human Data: Major congenital malformations that have been documented following isotretinoin exposure include malformations of the face, eyes, ears, skull, central nervous system, cardiovascular system, and thymus and parathyroid glands. External malformations include: skull; ear (including anotia, micropinna, small or absent external auditory canals); eye (including microphthalmia); facial dysmorphia and cleft palate. Internal abnormalities include: central nervous system (including cerebral and cerebellar malformations, hydrocephalus, microcephaly, cranial nerve deficit); cardiovascular; thymus gland; parathyroid hormone deficiency.

In some cases, death has occurred as a result of the malformations. Cases of IQ scores less than 85 with or without other abnormalities have been reported in children exposed in utero to isotretinoin. An increased risk of spontaneous abortion and premature births have been reported with isotretinoin exposure during pregnancy.

8.3 Females and Males of Reproductive Potential All patients who can become pregnant must comply with the iPLEDGE program requirements [see Warnings and Precautions (5.2) ]. Pregnancy Testing All patients who can get pregnant must comply with the iPLEDGE REMS requirements [see Warnings and Precautions ( 5.2 )] . Pregnancy Testing In patients who can get pregnant, pregnancy testing is required prior to, during, and after ABSORICA/ABSORICA LD treatment.

Pregnancy Testing Prior to Prescribing ABSORICA/ABSORICA LD: In patients who can get pregnant, only prescribe ABSORICA/ABSORICA LD after verification and documentation that they are not pregnant: Complete the first urine or serum pregnancy test (screening test) in a medical setting (e.g., prescriber’s office, clinic, laboratory) and verify and document that the test is negative, AND For patients with: Regular menstrual cycles, complete the second urine or serum pregnancy test (confirmatory test) in a medical setting (1) at least 30 days after the screening test and during the first five days of their menstrual period immediately preceding the beginning of ABSORICA/ABSORICA LD treatment, AND (2) after the patient has used their chosen pregnancy prevention methods (i.e., two forms of contraception or committed to abstinence) for at least 30 days. Verify and document that the confirmatory test is negative, OR Amenorrhea, irregular cycles, or using a contraceptive method that precludes withdrawal bleeding , complete the second urine or serum pregnancy test (confirmatory test) in a medical setting (1) at least 30 days after the screening test and immediately preceding the beginning of ABSORICA/ABSORICA LD treatment, AND (2) after the patient has used their chosen pregnancy prevention methods (i.e., two forms of contraception or committed to abstinence) for at least 30 days. Verify and document that the confirmatory test is negative. If a patient who can get pregnant has had negative screening and confirmatory pregnancy tests but they missed the 7-day prescription window (the patient has not obtained their ABSORICA/ABSORICA LD prescription within 7 days of the pregnancy test collection) and has not started…
