What the label states
Heartburn and acid indigestion
4 products in the FDA listing carry a label that states this use in its own words.
These are the label's claims, not ours. A product appears here because the Uses statement on its own FDA label mentions this, and for no other reason. This page does not say any of them works, does not compare them, and does not recommend one. If you are deciding what to take, that conversation belongs with a pharmacist.
Antacid labels. These are chewed or dissolved in the mouth but act on the stomach.
Which ingredients carry this claim
| Active ingredient | Products | Strength range |
