More than 580,000 bottles of prazosin hydrochloride, a blood pressure medication prescribed by millions of Americans, have been recalled due to high levels of a cancer-causing chemical impurity.
Details of the Recall
The voluntary recall was issued by Teva Pharmaceuticals after FDA testing found excessive levels of “N-nitroso Prazosin impurity C,” a substance linked to cancer risk with long-term exposure. The medication—used primarily to treat high blood pressure but also prescribed for PTSD-related nightmares—works by relaxing the blood vessels and improving blood flow.
FDA Risk Classification and Prazosin Hydrochloride
The FDA has designated this as a Class II recall, meaning temporary or medically reversible adverse health effects are possible, but the risk of serious long-term harm is considered remote. The recall covers 181,659 bottles of 1 mg capsules, 291,512 bottles of 2 mg capsules, and 107,673 bottles of 5 mg capsules, each ranging from 100 to 1,000 capsules per bottle, with expiration dates from October 2025 through February 2027.
What Patients Should Do
Patients taking the recalled medication are advised to consult their healthcare providers immediately for safe alternatives. According to the FDA, it’s important to follow proper disposal guidelines and avoid continued use of the affected product.
If you have questions about your blood pressure medication, check the label and lot number, and contact your pharmacy or physician for instructions. Health officials continue to monitor the recall and provide updates for patient safety.
