Relief of symptoms associated with gas including bloating, pressure, fullness, and flatulence, as well as acid indigestion and heartburn.
Simethicone acts as an antiflatulent by reducing the surface tension of gas bubbles, allowing them to combine and be more easily expelled. The antacid component neutralizes excess stomach acid to provide relief from heartburn and indigestion.
For best results, take after meals and at bedtime. Consult a doctor if symptoms persist beyond 2 weeks or if you are pregnant, nursing, or taking other medications. Keep out of reach of children. Do not exceed recommended dosage.
