What is simethicone?

Simethicone is used to treat the symptoms of gas, such as uncomfortable or painful pressure, fullness and bloating. Simethicone targets small bubbles of gas in the stomach and intestines. By changing the surface pressure of the bubbles, simethicone makes it easier for small bubbles to connect with other bubbles, reducing pain.

Simethicone is an ingredient in both over-the-counter and prescription drugs. Simethicone comes in many different gas relief medications, including Gas-X and Mylanta anti-gas products.
