By working together, these ingredients help neutralize stomach acid and reduce gas buildup, providing you with relief from these common digestive issues.

Uses

If you're experiencing discomfort from heartburn, a sour stomach, or acid indigestion, this medication can help relieve those symptoms. It also addresses issues related to gas, providing you with some much-needed comfort.

You can feel confident using this medication, as it has no known teratogenic effects (which means it doesn't cause birth defects) or nonteratogenic effects. This makes it a safe option for many individuals seeking relief from these common digestive issues.
