U.S. FDA: Multiple pharmaceutical companies recall over 580,000 bottles of blood pressure medication contaminated with carcinogens

On October 31 local time, the U.S. Food and Drug Administration (FDA) announced that several pharmaceutical companies are recalling over 580,000 bottles of the antihypertensive drug Prazosin hydrochloride contaminated with carcinogens. The FDA stated that Teva Pharmaceutical Industries USA and Mylan Pharmaceuticals initiated a voluntary nationwide recall earlier this month. This medication is used to dilate blood vessels and lower blood pressure, and it is also commonly used to treat nightmares and sleep issues related to post-traumatic stress disorder. The FDA noted in its announcement that some batches of the drug may contain nitrosamine impurities, which are potential carcinogenic compounds formed during the production or storage of medications. The regulatory agency has classified this recall as a "Class II recall."
