If you have acid reflux or other symptoms caused by stomach acidity, get to know your OTC medications.
Antacids neutralize the acid that your stomach makes. This can make you more comfortable. On the other hand, H2 receptor blockers and PPIs can block your stomach from making too much acid. This can allow the damage in your stomach and esophagus to heal.
Ask your doctor which is better for you.
