More than half a million bottles of blood pressure medication are being recalled over a cancer-causing chemical connected to the prescription drug, according to the U.S. Food and Drug Administration.
Teva Pharmaceuticals USA, based in Parsippany, New Jersey, issued a voluntary recall on Oct. 7 for some of the prazosin hydrochloride capsules it distributed, and the FDA classified it as a Class II risk level on Friday, Oct. 24.
The drug was approved by the FDA to treat high blood pressure, but sometimes prescribed off-label to help manage symptoms of post-traumatic stress disorder (PTSD), particularly nightmares and sleep problems. The medication works by relaxing blood vessels, improving blood flow and reducing blood pressure.
