Epogen and Neupogen (Epoetin alfa and Filgrastim)

Three reported incidents of product tampering. Specifically, the flip caps from the tops of eight vials from different lots of EPOGEN and NEUPOGEN were removed and the contents of the vials extracted. The contents were replaced with varying amounts of an aqueous solution and the vials were resealed in an apparent effort to conceal product theft.
