Blood-Pressure Drug Recalled Over Cancer-Linked Contaminant

The Food and Drug Administration (FDA) has announced a widespread recall of more than 580,000 bottles of the prescription drug Prazosin hydrochloride, used for high blood pressure (and sometimes nightmares tied to post-traumatic-stress disorder). The recall, issued by Teva Pharmaceuticals USA and its distributor AmerisourceBergen (Amerisource Health Services), was designated as a Class II recall on October 25, 2025.

The reason: the FDA found that certain batches of the medication contain excessive levels of a nitrosamine impurity known as “N-nitroso Prazosin impurity C,” a chemical compound that is classified as potentially carcinogenic.

Important Details

  • The recall covers 1 mg, 2 mg and 5 mg capsule strengths of prazosin hydrochloride, in bottle counts ranging from 100 to 1,000 capsules.
  • The affected lot expiration dates span from October 2025 through February 2027.
  • Because the risk is classified as Class II — “may cause temporary or medically reversible adverse health consequences” and wherein the probability of serious health effects is remote — the FDA emphasises: do not stop taking the medication without consulting your healthcare provider.

Why This Matters

While the immediate risk of cancer is considered low, the presence of nitrosamine impurities in a widely used medication raises important questions about manufacturing oversight, supply-chain quality and patient safety. Nitrosamines are known to form during manufacturing or storage of certain drugs and have been linked to past recalls and cancer-risk concerns.

For patients managing hypertension, the scenario presents a tough decision: stay on a medicine with impurity concerns, or switch to alternatives while maintaining blood-pressure control. Doctors and pharmacists may need to act quickly to guide patients and ensure continuity of care.

What Patients Should Do

  • Check your medicine. If you take prazosin hydrochloride, contact your pharmacy or doctor to verify whether your lot is part of the recall.
  • Don’t stop cold. Abruptly discontinuing a blood-pressure drug can be dangerous. Discuss substitution or alternative treatments.
  • Watch for symptoms. While the risk of immediate harm is low, ask your doctor about long-term monitoring if you’ve used the affected product for a prolonged period.
  • Report concerns. If you notice anything unusual with your medication – such as discoloration, unexpected side-effects or mismatch in packaging – report it to your pharmacist or the FDA (1-888-INFO-FDA).

Final Thoughts

This recall underscores the fact that even medications we assume are safe and stable can face manufacturing or contamination issues. For those affected, it’s a prompt to review and possibly update treatment options—but also a reminder of the importance of clear communication between patients, healthcare providers and regulators.
