Popular blood pressure drug recalled

August 12, 2026 - 21:30

A single batch of the widely used blood pressure drug valsartan, sold by Novartis under the brand name Diovan, has been recalled. The U.S. Food and Drug Administration announced the action, classifying it as a Class II recall. That designation means the product may cause temporary or medically reversible health problems, though the chance of serious harm is considered low.

The recall affects only one specific lot of the medication, not the entire supply. Patients who are currently taking Diovan or its generic versions are advised to check the lot number on their prescription bottle. If the number matches the recalled batch, they should contact their pharmacist or doctor for guidance. Stopping the medication suddenly is not recommended, as that could lead to a dangerous spike in blood pressure.

Valsartan belongs to a class of drugs known as ARBs, which work by relaxing blood vessels to lower pressure. It is commonly prescribed for hypertension and heart failure. This is not the first time valsartan products have faced scrutiny. In past years, some batches were recalled due to the presence of trace amounts of nitrosamine impurities, which are possible cancer-causing agents. However, the current recall is tied to a different issue, though the FDA has not disclosed the specific reason in its public notice.

Novartis said the recall is voluntary and limited in scope. The company is working with regulators to resolve the matter. For most patients, the risk is minimal, but anyone with concerns should speak with a healthcare provider rather than making changes on their own. Pharmacists can also help determine whether a different lot or an alternative blood pressure medication is appropriate.
