Blood pressure medication recall: More than half a million bottles of blood pressure medicine have been recalled due to the presence of a potential cancer-causing chemical, according to the U.S. Food and Drug Administration (FDA). Teva Pharmaceuticals USA, headquartered in Parsippany, New Jersey, issued a voluntary recall on October 7, 2025, for certain batches of prazosin hydrochloride capsules. The FDA later classified the situation as a Class II risk on October 24, 2025, which means that use or exposure could cause temporary or medically reversible health issues, though the chance of serious harm is considered low.Prazosin hydrochloride: FDA Recalls Blood Pressure MedicineTeva Pharmaceuticals announced the voluntary recall after the FDA identified a potential impurity in some batches of prazosin hydrochloride. A Class II classification indicates that exposure to the affected medication could cause short-term or reversible health problems, but the likelihood of severe consequences is low.Prazosin hydrochloride is an FDA-approved medication for treating high blood pressure, but it is also prescribed off-label to help people with post-traumatic stress disorder (PTSD) manage nightmares and sleep disturbances. The drug works by relaxing blood vessels, which helps lower blood pressure and improve blood flow.Blood Pressure Medication Recall: What Chemical Impurity Caused the Blood Pressure Medication Recall?The recall applies to three different dosage strengths that were distributed across the United States. The affected capsules were found to contain elevated levels of N-nitroso prazosin impurity, a nitrosamine compound that may increase the risk of cancer with prolonged exposure.The FDA has stated that nitrosamine impurities like N-nitroso Prazosin impurity C can be harmful over time. However, because the recall falls under the Class II category, the potential for serious or long-term effects is low. In total, more than 580,000 bottles of prazosin hydrochloride are included in the recall. Patients currently taking the medicine for blood pressure or other conditions are advised to check their bottles, contact their pharmacist, and safely dispose of any affected medication.Prazosin hydrochloride: Blood Pressure Recalled ProductsAccording to USA Today, the recall involves the following:1 mg capsules: 181,659 bottles (NDC 0093-4067-01 and 0093-4067-10), lot numbers 3010544A and 3010545A, with an expiry date of October 2025.2 mg capsules: 291,512 bottles (NDC 0093-4068-01 and 0093-4068-10) across several lot numbers, expiring between October 2025 and July 2026.5 mg capsules: 107,673 bottles (NDC 0093-4069-01, 0093-4069-52, and 0093-4069-05) across various lot numbers, with expiry dates extending into 2026.Prazosin hydrochloride: What Should People Do With Recalled Medication?Although neither Teva nor the FDA has issued specific instructions for patients, GoodRx advises those affected to verify their medication’s lot number, contact their pharmacist and prescribing doctor, and dispose of the recalled product safely.Teva has started notifying customers by mail, and the recall process is ongoing.
