Simethicone: Uses & Dosing information

Simethicone allows gas bubbles in the stomach and intestines to come together more easily, which allows for easier passage of gas.

Simethicone is used to relieve painful pressure caused by excess gas in the stomach and intestines. Simethicone is for use in babies, children, and adults.
