More than 13,500 bottles of chlorthalidone, a widely used blood pressure medication, have been recalled across the United States after the tablets failed a quality test, according to the Food and Drug Administration.

The recall covers 25 mg chlorthalidone tablets made by Inventia Healthcare Limited, sold in 100-count bottles with NDC number 64980-599-01, batch number RISA24002 and an expiration date of April 2027.

The tablets failed dissolution specifications, meaning they did not release the active ingredient the way they should in testing. For people managing high blood pressure, a pill that works less well could raise the risk of heart attack, stroke or kidney damage over time. It is the second such recall in three months.

The FDA classified it as a Class II recall, meaning the product may cause temporary or medically reversible health problems, or the chance of serious harm is remote.

If you take chlorthalidone, check the bottle for the batch number. Do not stop taking blood pressure medication on your own, because stopping suddenly can be dangerous. Call your doctor or pharmacist for a replacement.
