Pharmaceutical giant Haleon announced that it is recalling multiple lots and strengths of its over-the-counter anti-bloating medication Gas-X, according to a Food and Drug Administration (FDA) notice published June 4.
The impacted products may have been contaminated “with a diluted propylene glycol-based coolant from a machine leakage during the packaging process,” the notice stated.
“There is a potential that ingestion of the softgels contaminated with the diluted propylene glycol-based coolant may result in adverse events such as nausea, vomiting, abdominal pain, and diarrhea,” it said.
Propylene glycol is a liquid used by several different industries, including as a solvent in food colorings, flavorings, and pharmaceuticals, although it is also used to make resins, brake fluids, antifreeze, and other industrial products, health officials say. Overexposure to the liquid can cause vomiting or nausea, dizziness, headaches, or lightheadedness.
Haleon said in the notice that so far, it has not received any reports of adverse reactions to the Gas-X products.
Lots Under Recall
The company said that its Gas-X Extra Strength Softgels “are uniquely identified as a green capsule and found in packaging with a green band.”
The recalled lots include :
-
Gas-X Extra Strength Softgels (120 ct.) with a UPC of 300674350419 and lot numbers of TL8K, YH9X, and YH9Y. All three lots have an expiration date of Nov. 30, 2028. They were distributed between April 13, 2026, and May 5, 2026.
-
Gas-X Extra Strength Softgels (72 ct.) with a UPC of 300439005721 and the lot number X78N. The lot has an expiration date of Nov. 30, 2028, and they were distributed between May 5, 2026, and May 14, 2026.
Consumers who purchased Gas-X Extra Strength medications after April 13 should see if the lot number is among those recalled. If so, they are advised to stop taking the medication and contact Haleon if they are seeking a refund.
People who took the medication and experienced health issues related to taking the product should contact a healthcare provider or physician.
The recall was initiated with the knowledge of the FDA, Haleon said in the news release.
No other lots of the Gas-X Extra Strength medication were affected. The company said that its Gas-X Ultra, Gas-X Maximum, and Gas-X Ultimate products were not impacted by this recall.
While the recall notices did not say where the impacted lots of medication were sold, Gas-X is sold in stores across the United States and via major online retailers such as Amazon or Walmart.
Another Gas-X Product Under Recall
A separate recall of a Gas-X product was initiated in late May for a different reason.
The FDA said in a notice that 285,330 blister cards of Gas-X, which contains simethicone in 125-milligram doses, in 120-count soft gel packs, were under recall due to “incomplete inactive ingredient information on the carton labeling.”
Gas-X contains the drug simethicone as its active ingredient. Simethicone is commonly used to treat gas symptoms such as feeling full, pressure, and bloating, according to the Cleveland Clinic. It’s also used during preparations for some medical procedures for the colon, such as colonoscopies.
