Second Lot of Counterfeit Serostim Surfaces, Serono Warns Customers

May 21, 2001

A lot of drugs labeled as Serono's AIDS-wasting medication Serostim (somatropin, rDNA origin), bearing the lot number MNH605A, is counterfeit, the Norwell, Mass.-based Serono said Friday. The company has sent notice to wholesale distributors, pharmacies, physicians and AIDS service groups telling them to immediately return any product labeled with that lot number. An investigation by the Food and Drug Administration has so far revealed that the fake product contains a "small amount" of human growth hormone -- but not the recombinant human growth hormone used in Serostim -- and "significantly less" growth hormone than the genuine product, said Serono spokesperson Carolyn Castel.
