A national registry on Friday began accepting names of Americans who take the anti-acne drug Accutane, part of a federal effort to limit use of the birth-defect-causing drug by pregnant women.

Doctors, wholesalers and pharmacies had until Friday to register with the computerized "iPledge" registry in order to continue prescribing or selling Accutane and any of the three generic versions of the drug, known as isotretinoin. Generic versions are sold as Amnesteem, Claravis or Sotret. (excite.com)
