FDA recalls blood pressure medication: Reason, affected drugs, and should you stop taking the pills?

The US Food and Drug Administration (FDA) has announced a nationwide recall of blood pressure medication. The Class II recall affects more than 25,000 bottles of 25 mg Chlorthalidone tablets manufactured by Inventia Healthcare Limited over concerns that the tablets do not meet required dissolution specifications.

The recall affects Chlorthalidone tablets with expiration date of April 2027. As per FDA, exposure to the recalled medicine could cause temporary or medically reversible health consequences, while the likelihood of serious adverse health effects is considered low.

Why was Chlorthalidone recalled?

According to the FDA, the affected Chlorthalidone tablets failed dissolution testing which is an important quality standard for tablets because it determines how quickly and effectively a medicine dissolves after it is taken. If a tablet does not dissolve at the required rate, the active ingredient may not be absorbed into the body as intended and could potentially affect how well the medicine works.


The initial recall was issued on June 5, 2026, involving 11,460 bottles. A second recall was issued on September 3, 2026, covering another 13,567 bottles. Together, the recalls affect more than 25,000 bottles of the medication.

Which Chlorthalidone tablets are recalled?

The recalled Chlorthalidone 25 mg tablets were manufactured by Inventia Healthcare Limited with batch numbers RISA24001, RISB24002, and RISA24002. The associated FDA recall numbers include D-0610-2026 and D-0852-2026. The recalled medicine was distributed in bottles containing either 100 tablets or 1,000 tablets, with an expiration date of April 2027.

Patients are thus advised to check their medication packaging and compare the batch information with the FDA recall details before taking any action.

What is Chlorthalidone used for?

Chlorthalidone is a diuretic, commonly known as a "water pill," that is used to treat high blood pressure and fluid retention. The medicine works by helping the kidneys remove excess sodium and water from the body through urine. This reduction in fluid can help lower blood pressure and reduce swelling caused by fluid retention.

Because Chlorthalidone is prescribed to manage conditions such as hypertension, abruptly stopping the medication without medical advice may carry risks.

Should you stop taking recalled Chlorthalidone?

The FDA advises that people generally should not stop taking a recalled medicine without speaking with their healthcare provider, unless the manufacturer or FDA provides different instructions.

For Class II recalls, the FDA notes that consumers can generally continue taking the medication unless the recalling company gives other instructions.

This is particularly important for blood pressure medicines because suddenly stopping treatment could cause blood pressure to rise.

Patients who have the recalled Chlorthalidone tablets should contact their doctor or pharmacist for advice. A healthcare professional can determine whether the medicine should be continued, replaced or otherwise managed based on the patient's individual circumstances.

What should patients do if they have the recalled tablets?

If you have Chlorthalidone 25 mg tablets, check the bottle for the manufacturer, strength, batch number and expiration date. If the product matches the recalled batches, contact your doctor or pharmacist before making changes to your treatment.

Patients should also ask their pharmacy whether an unaffected replacement supply is available. Do not dispose of a prescription medicine simply because it appears on a recall list without first confirming the appropriate course of action with a healthcare professional. The safest way to handle a recalled medicine can depend on the medication and the reason for the recall.

Other blood pressure medication recalls

The Chlorthalidone recall follows other recalls involving medicines used to treat high blood pressure. In October 2025, more than half a million bottles of Prazosin Hydrochloride were recalled because of concerns involving potentially unsafe levels of a cancer-causing chemical.

As with the Chlorthalidone recall, patients were advised to seek guidance from their healthcare providers or pharmacies.
