Dear Health Care Professional:

Amgen Inc. recently became aware of the existence in the U.S. of a counterfeit drug product labeled as EPOGEN(R) (Epoetin alfa) 40,000 U/ml vials in ten-pack boxes, lot number P002970 and expiration 7/03. In cooperation with the U.S. Food and Drug Administration (FDA), Amgen is informing patients, physicians, pharmacies, and wholesalers about this potentially serious health risk. EPOGEN(R) is primarily used for the treatment of anemia associated with chronic renal failure for patients on dialysis.

The counterfeit vials examined by Amgen to date contain a clear liquid that contains active ingredient. However, the concentration of active ingredient is approximately 20 times lower than expected for EPOGEN(R) 40,000 U/ml vials.

Pharmacists and all other health care professionals should carefully examine EPOGEN(R) before use. The following information may help in determining if the product you have is counterfeit.

In order to view pictures illustrating these differences, please log onto Amgen's web site at

If you receive any product that you suspect is counterfeit, quarantine it and store it under labeled conditions. Please promptly contact FDA for further instructions at 1 800 835 4709.

If you have questions about EPOGEN(R), please contact Amgen Medical Information at 1 800 772 6436. Please convey this information to your staff and any others who administer EPOGEN(R). You should instruct them on what to look for and what to do in the event they find a suspect counterfeit vial.

Amgen does not recommend the purchase of Amgen products from wholesalers that do not currently purchase EPOGEN(R) directly from Amgen. A list of wholesalers that currently purchase EPOGEN(R) directly from Amgen can be found on its website at The parties on this list are the only wholesalers whom Amgen currently sells to for distribution of its products. If you have purchased Amgen product from another source, you should verify the origin of that product by contacting the distributor.

Amgen is cooperating fully with the FDA to investigate this matter and prevent the further distribution of counterfeit product. To Amgen's knowledge, the counterfeit product has only been found in distribution in the U.S.
