Isotretinoin is primarily used as a treatment for severe acne. The most common adverse effects are a transient worsening of acne (lasting 2. Uncommon and rare side effects include muscle aches and pains (myalgias), and headaches. Isotretinoin is known to cause birth defects due to in utero exposure because of the molecule's close resemblance to retinoic acid, a natural vitamin A derivative which controls normal embryonic development. In the United States a special procedure is required to obtain the pharmaceutical. In most other countries a consent form is required which explains these risks. Women taking isotretinoin must not get pregnant during, and for 1 month after isotretinoin therapy. Sexual abstinence, or effective contraception is mandatory during this period.

Under it, dermatologists must register their patients on the system before prescribing isotretinoin. Pharmacists must then verify the prescription on the i. PLEDGE website before dispensing isotretinoin. The website allows no more than thirty days' supply of the drug to be prescribed or dispensed; and after issuance, another prescription may not be written for at least 3. Prescriptions expire from i. PLEDGE if not picked up from the pharmacy seven days after issuance. Physicians and pharmacists must verify written prescriptions on the system before filling an isotretinoin prescription. Due to the teratogenic effects of isotretinoin, i. PLEDGE makes additional requirements of female patients filling prescriptions for the drug: women with child- bearing potential must commit to using two forms of effective contraception simultaneously for the duration of isotretinoin therapy and for a month immediately preceding and a month immediately following therapy. In Mexico and Brazil the use of the drug is restricted: official identification and a signature must be provided by the patient before an isotretinoin prescription will be filled by a pharmacist.

Three metabolites of Isotretinoin are detectable in human plasma after oral administration: 4- oxo- isotretinoin, retinoid acid (tretinoin), and 4- oxo- retinoic acid (4- oxo- tretinoin). Isotretinoin also oxidizes, irreversibly, to 4- oxo- isotretinoin. After an orally- administered, 8. C- isotretinoin, 1. C- activity in blood declines with a half- life of 9. Experiments completed in 1. However, they also showed that the compound was likely to cause birth defects, so in light of the events around thalidomide, Roche abandoned the product. In 1. 97. 5, Gary Peck and Frank Yoder independently rediscovered the drug's use as a treatment of cystic acne while studying it as a treatment for lamellar ichthyosis, and published that work. Roche resumed work on the drug, In clinical trials, subjects were carefully screened to avoid including women who were or might become pregnant. Roche's New Drug Application for isotretinoin for the treatment of acne included data showing that the drug caused birth defects in rabbits. The FDA approved the application in 1. Scientists involved in the clinical trials published articles warning of birth defects at the same time the drug was launched in the US, but nonetheless isotretinoin was taken up quickly and widely, both among dermatologists and general practitioners. Cases of birth defects showed up in the first year, leading the FDA to begin publishing case reports and to Roche sending warning letters to doctors and placing warning stickers on drug bottles, and including stronger warnings on the label. Lawsuits against Roche started to be filed. In 1. 98. 3 the FDA's advisory committee was convened and recommended stronger measures, which the FDA took and were that time unprecedented: warning blood banks not to accept blood from people taking the drug, and adding a warning to the label advising women to start taking contraceptives a month before starting the drug. However use of the drug continued to grow, as did the number of babies born with birth defects. In 1. 98. 5 the label was updated to include a boxed warning. In early 1. 98. 8 the FDA called for another advisory committee, and FDA employees prepared an internal memo estimating that around 1,0. The memo was leaked to the New York Times. In the committee meeting, dermatologists and Roche each argued to keep the drug on the market but to increase education efforts; pediatricians and the CDC argued to withdraw the drug from the market.
