More than 13,000 bottles of a prescription blood pressure medication are being recalled nationwide, for the second time, after the tablets failed a quality test, according to the U.S. Food and Drug Administration.

The recall covers chlorthalidone tablets, a medication used to treat high blood pressure and certain types of fluid retention. It was initially issued earlier this year because the pills don’t dissolve properly. At that time, more than 11,400 bottles were involved.

Inventia Healthcare Limited, an India-based drug manufacturer, voluntarily began the recall on Sept. 3. The FDA classified it as a Class II recall on Sept. 17.

A Class II recall means use of the product could cause temporary or medically reversible health problems, although the likelihood of serious harm is considered remote, according to the FDA.

The recall now includes 13,567 bottles, an FDA enforcement report said. The bottles are from Batch No. RISA24002, with an expiration date of April 2027.

According to the FDA, the pills are prescription-only and were distributed nationwide.

The Mayo Clinic reports that chlorthalidone “is used alone or together with other medicines to treat high blood pressure (hypertension).” It can also be used to treat fluid retention.

It’s not the only recent blood pressure medication recall.

In October of 2025, more than half a million bottles of Prazosin Hydrochloride were recalled over concerns that they contained unsafe levels of a cancer-causing chemical, with the drugmaker telling patients who take the pills to contact their doctor or pharmacy if they have the product.
