Aluminum Oxide / Simethicone
This combination medication contains an antacid (aluminum oxide) and an antiflatulent (simethicone) to provide dual relief from digestive discomfort. It is commonly used to treat symptoms of excess stomach acid such as heartburn and indigestion, while also relieving gas, bloating, and pressure caused by trapped air in the digestive tract. The two ingredients work together to address both acid-related and gas-related symptoms simultaneously.

Used to relieve symptoms of acid indigestion, heartburn, gastroesophageal reflux (GERD), and gas-related discomfort including bloating, pressure, and flatulence.
Aluminum oxide acts as an antacid by neutralizing excess stomach acid, while simethicone works as an antiflatulent by reducing surface tension in gas bubbles, allowing them to combine and be more easily expelled.
May interact with other medications by affecting their absorption; take doses 2 hours apart from other drugs. Side effects may include constipation (from aluminum) or mild diarrhea. Consult a healthcare provider if symptoms persist beyond 2 weeks or if you have kidney disease.
