More than half a million bottles of blood thinners are being recalled over cancer-causing chemicals linked to the prescription drug, according to the US Food and Drug Administration.
Teva Pharmaceuticals USA, based in PopPany, New Jersey, issued a voluntary recall on Oct. 7 of some prazosin hydrochloride caplules class I II risks on Friday, Oct. 24.
This drug was approved by the FDA to treat high blood pressure, but is sometimes prescribed off-label to help treat symptoms of post-traumatic stress disorder (PTSD), especially sleep problems. Medicines work by relaxing blood vessels, improving blood flow and lowering blood pressure.
