Serostim [somatropin (rDNA origin) for injection] Press Release Jan 2001

FDA posts safety alerts, public health advisories, press releases and other notices from companies as a service to health professionals, consumers and other interested parties. Although FDA approves medical products, FDA does not endorse either the product or the company.


This is a press release from Serono, Inc. Contact the company for a copy of any referenced enclosures.


Norwell, MA, January 22, 2001 — Serono, Inc., in cooperation with the U.S. Food and Drug Administration (FDA), is informing patients, physicians and distributing pharmacies about a counterfeit version of Serono’s Serostim 6mg [somatropin (rDNA origin) for injection]. Serostim is approved for the treatment of AIDS wasting.

Unlike genuine Serostim 6mg, the counterfeit product is of unknown safety and efficacy and may pose a health risk to patients. The counterfeit product, which is definitely not Serostim, was neither manufactured nor distributed by Serono.

Serono recently became aware of the existence of the counterfeit drug. Serono has issued a "Notification of Potential Counterfeit Product" to wholesalers, pharmacists, physicians and AIDS service organizations to alert them, in an effort to prevent patients currently undergoing Serostim therapy from receiving the counterfeit product. The counterfeit product has been packaged to appear as drug product lot number MNK612A and is readily distinguishable from authentic Serostim by the following features:
