In late October 2025, Teva Pharmaceuticals and distributor Amerisource Health Services issued a voluntary nationwide recall for more than 580,000 bottles of prazosin hydrochloride capsules. The FDA classified it as a Class II recall because testing showed elevated levels of nitrosamine impurities — chemicals that can form during manufacturing or storage and are considered potentially concerning with long-term exposure.
Prazosin is an alpha-blocker often used to help manage high blood pressure by relaxing blood vessels. It is also sometimes prescribed for other needs like certain symptoms related to PTSD. The recall affects specific lots in 1 mg, 2 mg, and 5 mg strengths, with expiration dates ranging into 2025 and 2026.
But here’s what matters most for you: not every bottle of blood pressure medication is involved, and not every person taking prazosin needs to panic. The FDA emphasizes that the risk from these low-level impurities is generally considered small, especially for short-term exposure. Still, the agency and manufacturers took action out of an abundance of caution to protect public health.
