Haleon Voluntarily Recalls Gas-X Extra Strength Softgels Due to Machine Leak Contamination

Haleon is voluntarily recalling four lots of Gas-X Extra Strength Softgels after a packaging machine leak may have contaminated the capsules with coolant. The recall covers products distributed nationwide between April 13 and May 14, 2026, according to FDA.
The affected lots include three versions of the 120-count product (Lots TL8K, YH9X, YH9Y) and one 72-count version (Lot X78N), all with a November 30, 2028 expiration date. As of June 5, 2026, no adverse events have been reported, WCNC-TV noted.
The contamination came from a diluted propylene glycol-based coolant — a fluid used to transfer heat in pharmaceutical plants. A packaging machine leaked the substance into the production environment. Haleon confirmed the root cause on June 5 and said repairs are complete, according to WCNC-TV.
The FDA warned that swallowing the affected softgels could cause "nausea, vomiting, abdominal pain and diarrhea," according to FDA. Propylene glycol is generally considered safe in small amounts, but industrial leaks can introduce levels that irritate the gut lining.
Consumers should check two UPC codes: 300674350419 for the 120-count and 300439005721 for the 72-count. All four lots share the same expiration date: November 30, 2028. Haleon issued its recall press release on June 4, 2026, according to Business Wire.
Anyone who has one of the recalled products can contact Haleon's Consumer Relations team at 1-800-245-1040 to request a return and reimbursement. The recall is voluntary, meaning Haleon acted without being forced by regulators.
This is not Haleon's first Gas-X problem in 2026. On May 11, the company recalled 285,330 packages of Gas-X Simethicone 125 mg Softgels due to incomplete ingredient labeling. The FDA classified that event as a Class II recall — meaning it posed a temporary but reversible health risk — on May 19, according to ConsumerLab.
Consumer advocates have pointed to a pattern of problems at Haleon facilities. The company also recalled eight lots of Robitussin Honey CF Max in January 2024 due to microbial contamination, which posed a serious risk to immunocompromised users, The Guardian reported.
Investors did not panic. Haleon's stock (NYSE: HLN) rose 2.52% on the day the recall was announced, June 4, according to Barchart. Analysts credit the company's ongoing share buyback program, announced in March 2026, for cushioning the news.
The voluntary nature of the recall also helped. Companies that self-report contamination issues tend to face less regulatory backlash than those subject to mandatory FDA seizures. Haleon said it has put corrective and preventative actions in place to stop future machine leaks.
