The U.S. Food and Drug Administration said the recalled medication, chlorthalidone, doesn’t dissolve properly, which could impact its potency. Learn which lots were affected.
More than 25,000 bottles of the blood pressure medication chlorthalidone have been recalled because the tablets may not dissolve correctly in the body, according to the U.S. Food and Drug Administration (FDA).
Chlorthalidone is a diuretic drug prescribed to treat high blood pressure, per Mayo Clinic. Diuretics reduce the amount of water in the body, which helps to lower blood pressure.
The India-based manufacturer, Inventia Healthcare, first recalled about 11,500 bottles of generic 25 milligram (mg) chlorthalidone tablets in June. The company issued a secondary recall of about 13,500 more bottles on September 3, 2026. The FDA lists both recalls as class 2, meaning the medication could “cause temporary or medically reversible adverse health consequences,” and that the likelihood of serious complications is remote.
The recalled bottles were distributed nationwide, according to the FDA reports. The recalled batches have an expiration date of 04/2027, and bear the following lot codes:
RISA24001
RISA24002
RISB24002
The name of a drug’s manufacturer and lot numbers can often be found on the label of your medication.
For class 2 recalls, the FDA says you “can generally continue taking the medicine unless the recalling company provides other instructions.” It may be risky to your health to stop taking the recalled medication without a replacement. If you have concerns about your medicine, reach out to your pharmacy or healthcare provider.
