How do acid reducers work?
Acid reducers decrease the amount of acid the stomach makes. This can help protect the esophagus, stomach, and intestines from getting damaged. It can also help heal damage from an ulcer or from inflammation of the esophagus (esophagitis).
What about side effects?
All medicines can cause side effects. Many people don't have side effects. And minor side effects sometimes go away after a while.
But sometimes side effects can be a problem or can be serious.
- H2 blockers. They can sometimes cause headaches, dizziness, diarrhea or constipation, or nausea and vomiting.
- Proton pump inhibitors. Headaches and diarrhea are the most common side effects. Using PPIs for a long time can increase your risk for infections or broken bones.
