The counterfeit product is being packaged to look like the real Serostim drug. To date, all reports have involved lot number MNK612A. However, the counterfeit product is distinguishable from the authentic Serostim.
Serono has informed the U.S. Food and Drug Administration Office of Criminal Investigation (FDA). Serono has also shared this information with wholesalers, pharmacists and physicians prescribing Serostim in an effort to prevent patients from receiving the counterfeit product.
Anyone concerned that they may have received the counterfeit product should call Serono's product information group at 1-888-275-7376.
