Metformin is a medication used to treat Type 2 diabetes. The drug has many common side effects and a few serious ones. According to MEDTV, up to 12 percent of people using Metrormin develop gas.
The dosage of Metformin can be started small and gradually increased to avoid side effects, according to MedlinePlus. The dosage is usually increased no more often than once every one or two weeks, as the body begins to tolerate the drug. Metformin comes in liquid, tablet and extended-release form. The long-acting, or extended release, is the most tolerated form. The tablets should be swallowed whole rather than chewed or crushed. Taking the medication on a full stomach may help with digestive issues, and many people find that once they are on the medication for a while, their digestive issues go away on their own; however, others find that their side effects increase with time.
Dietary supplements such as Beano could reduce gas in general, according to WebMD, as could avoiding gas-producing foods such as beans, certain vegetables like broccoli and cabbage, fried foods, fatty foods and milk for those with lactose intolerance. Simethicone is an over-the-counter medication used to treat gas in babies. According to WebMD, it can also be used to treat gas in adults.
