Teva Pharmaceuticals USA and distributor Amerisource Health Services have issued a voluntary nationwide recall for more than 580,000 bottles of the blood pressure medication prazosin hydrochloride. According to the U.S. Food and Drug Administration, the recall was prompted by concerns that the capsules may be contaminated with a potentially cancer-causing chemical.
Prazosin is prescribed to lower blood pressure by relaxing blood vessels. The medication is also used to treat nightmares and other sleep disturbances related to post-traumatic stress disorder.
The FDA has assigned the recall a Class II risk classification due to the potential presence of N-nitrosamine impurities. These substances, considered potential carcinogens, can sometimes form during the manufacturing or storage of pharmaceutical drugs.
