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 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 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
