Simethicone is widely used as an antifoaming agent to relieve symptoms of excess gas in the gastrointestinal tract, such as bloating, discomfort, and flatulence. It works by breaking down gas bubbles, making them easier to pass. It is commonly found in over-the-counter medications for digestive issues, including antacids and anti-gas products. Additionally, it is used in medical imaging procedures, such as endoscopy and radiology, to reduce foam that can interfere with clear visualization of the gastrointestinal tract. Simethicone is also incorporated into some infant colic drops to alleviate gas-related discomfort in babies. Its non-systemic nature ensures it is not absorbed into the body, making it safe for widespread use.
