How do they work?
Acid-reducing medicines work in two ways. H2 blockers and proton pump inhibitors (PPIs) lower the amount of acid your stomach makes. They don't work on the acid that's already there. Antacids work by making stomach juices less acidic. But your heartburn may come back as your stomach makes more acid.
What about side effects?
Many people don't have side effects. And minor side effects might go away after a while.
H2 blockers can cause headaches or make you dizzy. They might cause diarrhea or constipation. You may have nausea and vomiting.
PPIs can cause headaches and diarrhea. Using them for a long time may raise your risk for infections or broken bones.
Some antacids can cause constipation or diarrhea. The brands vary in the ingredients they use. They can have different side effects.
If you use too much heartburn medicine, your body may not get enough of some minerals from your food.
