Lefoam 15 ml is a medication that contains simethicone, which is primarily used to relieve symptoms of excess gas in the gastrointestinal tract, such as bloating, discomfort, and pressure. Simethicone works by reducing the surface tension of gas bubbles, allowing them to combine and be expelled more easily from the digestive system. Lefoam is often used to alleviate gas-related discomfort after meals or during episodes of digestive distress. It is typically well-tolerated and can be taken as needed, but it is important to follow the dosage instructions provided by a healthcare professional to ensure safe and effective use.
