The U.S. Food and Drug Administration (FDA) has announced a nationwide recall of the popular blood pressure medicine, prazosin hydrochloride, after discovering traces of potentially cancer-causing impurities. The recall affects over 580,000 bottles of the drug that were distributed across the country by Teva Pharmaceuticals USA and Amerisource Health Services.
Why Did the FDA Recall Prazosin?
The FDA’s investigation found that some batches of prazosin contained nitrosamines, a type of chemical impurity that can develop during the manufacturing or storage process of certain drugs. These impurities are considered potentially cancer-causing when present above safe limits over long-term use.
The agency classified the case as a Class II recall, which means the risk of serious harm is relatively low, but patients could still experience temporary or reversible health effects. To prevent any danger, the manufacturers decided to voluntarily pull the affected bottles from pharmacies and medical suppliers nationwide.
What Is Prazosin and Who Takes It?

Prazosin hydrochloride is commonly prescribed to treat high blood pressure by helping blood vessels relax, improving blood flow, and easing the workload on the heart. Interestingly, it’s also prescribed to help with nightmares and sleep problems related to post-traumatic stress disorder (PTSD).
The medication has been effective for many people, but this recall is a reminder that even trusted drugs can face manufacturing challenges that affect their safety.
Comparison: Prazosin vs. Other Blood Pressure Medicines
| Feature | Prazosin Hydrochloride | Other BP Medications (Lisinopril, Amlodipine) |
|---|---|---|
| Main Function | Relaxes blood vessels | Lowers BP by easing heart strain or relaxing arteries |
| Additional Uses | PTSD-related sleep issues | Focused mainly on hypertension |
| Recall Reason | Nitrosamine contamination | Usually formulation or labeling issues |
| FDA Risk Level | Class II | Varies by recall type |
What Should Patients Do Now?

If you are taking prazosin, the first step is to check the manufacturer name and batch number on your medicine bottle. If it matches the recalled lots, contact your pharmacist or healthcare provider right away. They can confirm if your prescription is affected and guide you on what to do next.
Importantly, do not stop taking your medication suddenly. Abruptly discontinuing blood pressure medicine can cause dangerous spikes in blood pressure. Your doctor can help you find a safe replacement or unaffected batch.
The FDA’s Commitment to Patient Safety
The FDA continues to work closely with manufacturers to prevent nitrosamine formation and improve the overall quality of medications. These steps include stricter manufacturing standards, better testing methods, and stronger oversight to protect patients from contamination risks.
Final Thoughts
The FDA prazosin recall 2025 highlights how vital drug safety monitoring is for public health. While recalls can sound alarming, they are actually a sign that the system is working — identifying and removing unsafe products before they can cause harm.
Patients are encouraged to stay informed, keep regular contact with their doctors, and always verify medication safety. Responsible manufacturing and transparent communication will continue to play a key role in keeping treatments both effective and safe for everyone.
