What Is Simethicone and How Does It Work?
Simethicone is an antiflatulent, a type of medicine that helps relieve the painful symptoms of too much gas in the stomach and intestines, including bloating, pressure, and fullness. Unlike other digestive aids, simethicone is not absorbed into the body and is considered physiologically inert, meaning it passes through the digestive tract and is excreted unchanged in the stool.
The active ingredient works by changing the surface tension of gas bubbles in the gastrointestinal (GI) tract. In a healthy digestive system, small gas bubbles are naturally formed, but these can become trapped and cause discomfort. Simethicone allows these mucus-surrounded gas bubbles to coalesce, or combine, into larger bubbles. These larger bubbles are then more easily eliminated through the normal processes of belching or flatulence. This mechanism explains why simethicone often provides quick relief for gas-related issues.
Products with Simethicone for Adults
Many popular over-the-counter (OTC) products for adults contain simethicone as the primary active ingredient. These products come in a variety of forms to suit different preferences and needs.
Key brands include:
- Gas-X: A well-known brand that offers simethicone in various strengths and forms, including softgels and chewable tablets.
- Phazyme: Available in different strengths, often with higher concentrations of simethicone than some other brands.
- Mylanta Gas: Sold as standalone gas relief products, separate from the brand's antacid formulas.
- Generic Store Brands: Most pharmacies and supermarkets offer their own generic versions of simethicone products, such as Equate (Walmart) and CVS Health brand gas relief.
Products with Simethicone for Infants
Simethicone is also formulated in lower doses specifically for infants to relieve discomfort from gas caused by air swallowing during feeding. These products typically come in liquid or drop form for easy administration.
Common infant-specific brands containing simethicone include:
- Mylicon: A long-standing and well-recognized brand of infant's gas relief drops.
- Little Remedies Gas Relief Drops: Another popular option for newborns and infants.
- Mommy's Bliss Gas Relief Drops: Offers a simethicone-based formula designed for baby gas.
- Parent's Choice Infant's Gas Relief (Walmart): A generic option for infant gas relief.
Combination Products Containing Simethicone
In addition to standalone products, simethicone is often combined with other medications to treat multiple digestive issues simultaneously. This is particularly common in products that address both heartburn and gas.
Examples of combination products include:
- Antacid combinations: Products like Mylanta (containing aluminum hydroxide, magnesium hydroxide, and simethicone) and Rolaids Multi-Symptom (with calcium carbonate, magnesium hydroxide, and simethicone) offer relief for gas, heartburn, and sour stomach.
- Loperamide combinations: Imodium Advanced combines the anti-diarrheal medication loperamide with simethicone to treat symptoms of both diarrhea and gas.
- Activated charcoal combinations: Products like Flatulex Tablets contain both activated charcoal and simethicone.

Is Simethicone Safe?
Simethicone is widely considered safe for most people, including pregnant women and breastfeeding mothers, because it is not absorbed by the body. It is a local-acting agent that only works on the gas bubbles within the GI tract.
As with any medication, however, it is important to use it as directed. While side effects are not common, some people may experience mild nausea or diarrhea. Severe allergic reactions are rare but require immediate medical attention. Always follow the dosage instructions on the product label and consult a healthcare provider if symptoms persist.
