The U.S. Food and Drug Administration confirmed a recall of over 500,000 bottles of prazosin hydrochloride, a blood pressure medication, due to possible contamination with a carcinogenic compound. The recall follows findings that the medication may contain nitrosamine impurities, which are classified as potentially cancer-causing, as reported by Click2Houston

Teva Pharmaceuticals USA and Amerisource Health Services issued voluntary recalls earlier this month for multiple strengths of prazosin capsules. The medication is used to manage blood pressure and to treat nightmares and sleep disturbances associated with post-traumatic stress disorder, according to Houston Chronicle

The U.S. Food and Drug Administration has classified a recent drug recall as a Class II risk, indicating that the presence of N-nitrosamine impurities is not immediately life-threatening but may increase cancer risk with long-term exposure. These impurities can form during manufacturing or storage. The recall emphasizes ongoing regulatory attention to medication quality and safety in the pharmaceutical industry.
