Costco recalls Gas-X Extra Strength softgels nationwide over contamination risk

The first place this recall lands is not the medicine aisle but the warehouse counter. Costco listed Gas-X Extra Strength Softgels 125mg, 120-count, item number 301341, as recalled for all U.S. locations, and that same item number is also used on Costco’s same-day listing, giving employees a clean way to verify what a member is holding when questions start at pharmacy, front-end, or returns.

The recall covers four lots of Gas-X Extra Strength Softgels after Haleon said the product may have been contaminated with a diluted propylene glycol-based coolant during a machine leak in packaging. The U.S. Food and Drug Administration posted the company’s voluntary nationwide recall notice on June 4, 2026, and said Haleon had not received reports of adverse events as of that date. The agency also said the recall was being conducted with FDA’s knowledge.

The affected lots are TL8K, YH9X, YH9Y, and X78N. The 120-count bottles in lots TL8K, YH9X, and YH9Y were distributed between April 13, 2026 and May 5, 2026, while the 72-count lot X78N was distributed between May 5, 2026 and May 14, 2026. The 120-count lots all expire on Nov. 30, 2028, and the 72-count lot carries the same expiration date. FDA said no other lots of Gas-X Extra Strength, Gas-X Ultra, Gas-X Maximum, or Gas-X Ultimate were impacted.

For warehouse employees, the problem is less about the product itself than the flood of member questions that follow a recall like this. Shoppers may not remember whether they bought the softgels in store or through same-day delivery, and the issue can show up anywhere from the front end to pharmacy to the customer service desk. Costco says it posts recall and product notice information as soon as possible, but the operational work still falls on employees who have to confirm the item number, match the lot code, and keep medical guidance in the right lane.

Haleon told consumers who bought the product on or after April 13, 2026 to check the lot number and stop taking it immediately if it matches. The company said it is notifying distributors and customers by letter, email, and phone, and arranging returns and reimbursement through Haleon Consumer Relations at 1-800-245-1040, Monday through Friday, 8 a.m. to 6 p.m. ET, or through mystory.us@haleon.com and the company’s contact form. Consumers who think they may have had a reaction were told to contact a physician or healthcare provider.
