From the Guidelines
Gas-X works by breaking up gas bubbles in the digestive tract, helping to relieve bloating, pressure, and discomfort, with its active ingredient simethicone acting as an anti-foaming agent, as supported by recent guidelines 1. The active ingredient in Gas-X is simethicone, which reduces the surface tension of gas bubbles in the stomach and intestines, causing them to combine into larger bubbles that can be more easily passed through burping or flatulence. Some key points to consider when using Gas-X include:
- The American Society for Gastrointestinal Endoscopy guidelines suggests the use of the lowest concentration (0.5 mL simethicone in 99.5 mL water; 0.5 % v/v; 10 mg/100 mL) and the smallest volume of simethicone if required to be administered through the endoscope 1.
- Intraprocedure simethicone further increases visualization based on some studies, with oral administration of these agents 15 to 30 minutes before endoscopy appearing safe and efficacious 1.
- Gas-X is available in various strengths and forms, including chewable tablets, softgels, and thin strips, with a typical dose of 60-125mg after meals and at bedtime, not exceeding 500mg daily.
- The medication is generally safe with few side effects, though some people may experience mild nausea or constipation, and it doesn't interact significantly with most other drugs since it works locally in the digestive tract and isn't absorbed into the bloodstream. It's worth noting that while Gas-X can provide quick relief from gas symptoms, it only treats the symptoms rather than preventing them, and its use should be guided by the most recent and highest quality evidence, such as the guidelines from the American Society for Gastrointestinal Endoscopy 1 and the AGA clinical practice update on high-quality upper endoscopy 1.

From the Research
How Gas X Works
- Gas X is an anti-gas medication that contains simethicone, an ingredient that helps to break up gas bubbles in the stomach and intestines 2, 3.
- Simethicone works by reducing the surface tension of gas bubbles, allowing them to be more easily absorbed by the body or passed through the digestive system 2.
- Gas X may also contain other ingredients, such as activated charcoal, which can help to absorb gas and reduce bloating 4, 3.
- Alpha-galactosidase, an enzyme that breaks down complex carbohydrates, may also be used to reduce gas production in the digestive system 5, 6.
- The combination of simethicone and activated charcoal in Gas X has been shown to be effective in reducing dyspeptic symptoms, such as abdominal fullness, bloating, and discomfort 2, 3.
- The efficacy of Gas X in reducing gas-related symptoms has been demonstrated in several studies, including a randomized prospective study in general practice 3.
