Haleon, the manufacturer of Gas-X, is voluntarily recalling four different lots of its Extra Strength Softgels after potential contamination was discovered from a machine leak during the packaging process.

The contamination could lead to gastrointestinal illness, according to a June 4 announcement from the U.S. Food and Drug Administration (FDA).

The recall affects Gas-X Extra Strength Softgels 125 mg in 120-count and 72-count packages, which were distributed to consumers nationwide between April 13 and May 14, 2026.

According to Haleon, the affected products may have been contaminated with a diluted propylene glycol-based coolant following a machine malfunction during packaging.

People who ingest the contaminated softgels could experience nausea, vomiting, abdominal pain, and diarrhea, according to the company.

Gas-X Extra Strength Softgels are an over-the-counter medication used to relieve pressure, bloating, and discomfort by breaking up gas bubbles in the digestive tract.

The softgels are green capsules packaged in boxes with a green band.

The recall covers three lots of the 120-count package and one lot of the 72-count package:

Gas-X Extra Strength Softgels, 120 count, UPC 300674350419, lot numbers TL8K, YH9X, and YH9Y, expiration date Nov. 30, 2028.
Gas-X Extra Strength Softgels, 72 count, UPC 300439005721, lot number X78N, expiration date Nov. 30, 2028.

The affected 120-count products were distributed from April 13 through May 5, 2026. The recalled 72-count product was distributed from May 5 through May 14, 2026.

Haleon said no other Gas-X products are included in the recall. Other lots of Gas-X Extra Strength, Gas-X Ultra, Gas-X Maximum, and Gas-X Ultimate remain unaffected.

According to the recall, consumers who purchased Gas-X Extra Strength Softgels on or after April 13 are advised to check the lot number on the package.

“If the lot number matches those impacted by this recall, stop taking the product immediately and contact the Haleon Consumer Relations team at +1-800-245-1040 (Monday through Friday 8 a.m. to 6 p.m. ET), or via [email protected] or https://haleon.help/en-us/contact-form to arrange for return of the product and request reimbursement,” according to the recall notice.

Haleon is a consumer health company headquartered in the United Kingdom with U.S. operations in New Jersey. It manufactures and markets several over-the-counter health products, including Advil, Centrum, Sensodyne, Theraflu, and TUMS.

“Consumer safety and product quality are our utmost priorities at Haleon,” the company said, adding that: “The root cause of the contamination has been identified and repaired. Corrective and preventative actions have been implemented to prevent future recurrence.”

No reports of adverse events related to this recall have been reported as of June 4, Haleon said.

Consumers who experience symptoms or other health problems after taking the recalled medication should contact a health care provider.

“Adverse reactions or quality problems experienced with the use of this product may be reported to the FDA's MedWatch Adverse Event Reporting program either online, by regular mail, or by fax,” the company said.
