At the FDA's Dermatologic Drugs Advisory Committee meeting in , some argued that Accutane should remain available as an acne treatment due to its exceptional efficacy and short treatment duration of fifteen to twenty weeks.
The committee voted four-to-three to allow Accutane to remain on the market with restricted access. A month later, the FDA announced that it would not follow the committee's recommendation to restrict the drug and instead issued new label warnings.
The PPP informed patients about the risks and benefits associated with isotretinoin, assisted physicians in complying with the package insert requirements, and evaluated a patient's ability to adhere to the requirement of not being or becoming pregnant one month before, during the course of, or one month after therapy.
The PPP protocol required that women use two forms of effective contraceptive during therapy, follow-up with officials through phone calls and questionnaires, and that they be offered reimbursement for contraceptive counseling and pregnancy testing.
Throughout the s, Hoffman-La Roche struggled with the consequences of Accutane's teratogenicity, and the company became involved in several court cases in Ohio and New Jersey about Accutane's teratogenicity. Of these cases, a number involved documents that allegedly indicated Hoffman-La Roche's negligence. In one case, Hoffman-La Roche sued Frank Yoder, the co-discoverer of Accutane's therapeutic effects, for his attempt to threaten the company into purchasing his private collection of documents, which according to Yoder, dealt with "the development, use, and misuse of isotretinoin Accutane.
After the case was settled, Hoffman-La Roche requested that the documents obtained by the Hammocks during discovery be sealed. Public Citizen challenged the court's decision to seal the documents.
Eventually, the New Jersey Supreme Court concluded that based on the policy of public access to information about health, safety, and welfare, the documents should be released. On 9 May , the documents were officially unsealed. The documents, however, did not provide the conclusive evidence that Public Citizen had expected; records showed that within a year of releasing the drug to the market, the company became anxious about Accutane and its related birth defects , and that the first documented Accutane baby was born on 29 April Although Yoder and Public Citizen failed to provide evidence that Hoffman-La Roche indeed withheld information from the FDA and researchers in the US, the three aforementioned cases prompted some to question Hoffman-La Roche's behavior, including the company's initial proposal to give Accutane a pregnancy risk rating of category C, meaning that the drug adversely affects fetuses, but that the benefits of the drug outweigh the risks for humans.
US patients using Accutane must enroll in this risk management program designed to prevent fetal exposure to isotretinoin.

During the first year of the program, women on isotretinoin became pregnant, about the same number of pregnancies as the year prior. However, much fewer patients were treated with isotretinoin. Since its release, Accutane has been prescribed to approximately five million people nationwide and twelve million worldwide, with eighty-five percent of all treated patients achieving complete elimination of acne after a course of therapy.
