From the FDA:
The U.S. Food & Drug Administration (FDA) is launching a special Web page to warn consumers about the dangers of buying isotretinoin (Accutane) online. Isotretinoin is a drug approved for the treatment of severe recalcitrant nodular acne that does not respond to antibiotics. Improperly used, isotretinoin can cause severe side effects, including birth defects. Serious mental health problems have also been reported with isotretinoin use.
The Web page, http://www.fda.gov/buyonline/accutane, will be positioned as a search result on Google and other search engines when a consumer initiates an online search for the drug under any one of its four names (Isotretinoin is sold under the brand name of Accutane and in generic versions called Amnesteem, Claravis, and Sotret.) The web page warns that the drug "should only be taken under the close supervision" of a physician or a pharmacist, and provides links to helpful information, including ways to check that drugs purchased online come from legitimate pharmacies.
"This Web page is yet another step we're taking to ensure the safe use of a drug that can provide significant health benefits when used properly, but that can also cause very serious side effects if used without supervision of a health professional," said Steven Galson, M.D.,M.P.H., Director, FDA's Center for Drug Evaluation and Research.
