FDA Recalls Teva Blood Pressure Drug After Cancer-Causing Contaminant Found

The FDA has issued a major recall of Teva Pharmaceuticals’ prazosin hydrochloride, a widely used blood pressure and PTSD medication, after discovering contamination with NDMA, a probable human carcinogen. According to a detailed report from the Cape Cod Times, multiple lots of prazosin were pulled from shelves nationwide after routine testing identified NDMA levels that exceeded federal safety limits.

This recall is especially alarming for patients in Massachusetts, where prazosin is frequently prescribed for hypertension, anxiety-related sleep disorders, and PTSD-related nightmares. Thousands of patients may have been exposed before the contamination was discovered.

What the FDA Found

In its official recall notice on FDA.gov, the agency confirmed that the contaminated prazosin batches contained NDMA above the acceptable daily intake threshold. NDMA exposure over long periods has been linked to cancers of the liver, stomach, colon, and pancreas.

The FDA urged pharmacies and wholesalers to immediately quarantine and return the recalled lots. However, the agency warned patients not to discontinue the medication without consulting a doctor, as abruptly stopping blood pressure treatment can be dangerous.

Why NDMA Contamination Keeps Affecting Blood Pressure Drugs

This recall is part of a troubling pattern. Over the past decade, NDMA contamination has repeatedly impacted the generic drug supply, especially blood pressure medications. As Reuters has reported in its coverage of hypertension drug recalls, NDMA often forms when certain manufacturing processes, solvents, or chemical reactions are not tightly controlled — something that is more likely to occur at overseas manufacturing facilities.

When quality control breaks down, impurities may go unnoticed until the drugs have already been distributed to patients. The prazosin recall highlights how fragile and inconsistent pharmaceutical oversight can be, especially in the generic drug market that supplies most U.S. prescriptions.

Connection to Previous Valsartan NDMA Cancer Lawsuits

This event mirrors the massive valsartan contamination crisis, which triggered nationwide litigation beginning in 2018. As documented by the FDA’s valsartan recall archive, millions of Americans unknowingly consumed NDMA-tainted valsartan for years before the hazard was identified.

Patients later filed lawsuits alleging that long-term NDMA exposure caused cancers including stomach, liver, and colorectal cancer. The discovery of similar contamination in Teva’s prazosin is a clear warning that the same systemic issues persist — and that patients may again face elevated cancer risks from daily medications meant to protect their health.

What Patients Should Do Now20

Patients who take Teva’s prazosin — or who have taken it recently — should take the following steps:

Check the FDA recall lot numbers

The full list is available directly on the FDA’s recall page. Compare the lot number on your pill bottle to ensure you are not taking a contaminated batch.

Consult your prescribing doctor before stopping the medication

Stopping prazosin suddenly can cause severe spikes in blood pressure, leading to headaches, dizziness, or serious cardiovascular risk.

Save your pill bottles and pharmacy records

This is critical if legal action or medical monitoring becomes necessary. Documentation will be essential for any future claims involving NDMA exposure.

Monitor for potential cancer symptoms

If you used the contaminated drug for an extended period, be aware of gastrointestinal changes, unexplained weight loss, persistent pain, or fatigue — and discuss concerns with a medical professional.

Why This Matters

NDMA contamination is a serious public health threat. Even at low levels, NDMA is considered dangerous — and multiple recent recalls show that contamination is becoming more common, not less. Each new recall erodes patient trust in medication safety and raises questions about whether pharmaceutical manufacturers are doing enough to prevent impurities.

The Teva recall proves that unsafe medications continue to make their way into pharmacies, exposing ordinary people to carcinogenic chemicals without their knowledge.
