Finding the right medication to treat a health condition—especially one as serious as high blood pressure—can often be determined after a doctor evaluates your overall health and risk factors. For people with high blood pressure, certain drugs, such as beta blockers or ACE inhibitors, may work best. But medications you may know as “water pills” might help some patients, say health experts.

According to the American Heart Association, diuretics are another type of medication that can be used to control blood pressure. These drugs can help regulate blood pressure by removing both excess water and salt from the body. Explains the Cleveland Clinic: “By clearing out extra fluids from your body, diuretics lower the amount of fluid in your blood that your heart has to pump.”

Now, one such medication is being flagged. On Monday, the U.S. Food and Drug Administration (FDA) announced that 962 cartons of Chlorthalidone Tablets have been recalled nationwide. The cartons, which are available via prescription, each contained a total of 50 tablets, per the FDA’s report.

Chlorthalidone is a diuretic and can be used to treat high blood pressure or reduce fluid retention related to conditions such as kidney disease, cirrhosis, or congestive heart failure, according to the Mayo Clinic. Chlorthalidone, a generic, is sometimes referred to by the brand names Thalitone or Hemiclor.

The recall, which was evidently first initiated on May 9 but not made public until this week, was put into effect due to “Failed Dissolution Specifications.”

The report does not further clarify what potential problems could arise from this issue, but the Contract Laboratory Network says inadequate or inconsistent dissolution “may lead to reduced drug absorption, delayed onset of action, or therapeutic failure—posing serious risks to patient health and regulatory compliance.”

As of June 9, the FDA has designated the recall as a Class II event, meaning the agency has determined the products involved may cause temporary or medically reversible adverse health effects.

Product details include:

  • Chlorthalidone Tablets, USP, 25 mg
  • 50 Tablets (5×10) Unit Dose cards per carton
  • Rx only
  • Lot #: 47947
  • Expiration Date: 05/31/2026

The recalling firm, AvKARE of Pulaski, Tennessee, was also named in a recall for more than 1.8 million eye drops in May due to several manufacturing issues.

Consumers should also be aware of a separate blood pressure medication that was recalled recently, which affected more than 732,000 bottles.
