This discovery resulted in the withdrawal of thalidomide from world markets in 1961. Thalidomide had not been sold in the United States because of careful scrutiny by the Food and Drug Administration (FDA), which insisted on more data regarding its neuropathic side effects as well as its safety during pregnancy.

For years, thalidomide was available only for strictly defined research purposes. In 1997, an FDA advisory committee recommended the approval of thalidomide for the treatment of erythema nodosum leprosum (ENL), which led to its July 1998 final approval for use in this condition in the United States. The FDA approval of thalidomide for ENL allows its use in many currently unapproved circumstances. This article reviews the pharmacology, adverse effects, and regulatory concerns and provides general therapeutic guidelines for the use of thalidomide in various dermatologic conditions.
