What Drug Companies and Drugs Are involved In Recent Warning Letters?
Eli Lilly was sent a letter by the FDA about their drug Cymbalta. Cymbalta is used for depression, generalized anxiety disorder, diabetic nerve pain and the pain ailment fibromyalgia. The FDA warned Eli Lilly that they did not properly display information about the drug's side effects.
Bayer was warned by the FDA about the marketing of its birth control implant drug Mirena. The agency warned that the marketing of the drug "overstates the efficacy" and "presents unsubstantiated claims."
Amylin Pharmaceuticals' drug Byetta (co-marketed with Eli Lilly) which is used for diabetes has marketing which the FDA views as promoting the drug for unapproved FDA use and also overstated the efficacy of the drug.
Cephalon used a promotional card for its drug Treanda (a lymphoma treatment) that was described by the FDA as "false or misleading because it omits important risk information."
