Treats occasional heartburn, acid indigestion, sour stomach, gas, bloating, and feelings of fullness or pressure in the stomach. Provides relief from discomfort associated with trapped gas in the digestive tract.
Aluminum Magnesium Silicate and Magnesium Hydroxide work together to neutralize excess stomach acid, providing acid neutralization and buffering capacity. Simethicone acts as an antiflatulent by reducing the surface tension of gas bubbles in the digestive tract, allowing them to combine and be more easily expelled or absorbed.
Take as directed on the product label or by your healthcare provider. Do not exceed recommended doses or use for extended periods without medical advice. Those with kidney disease should consult a doctor before use. If symptoms persist beyond two weeks, seek medical attention. Keep out of reach of children.
