What are antacids used for?

Antacids are non-prescription medicines that treat:

  • Indigestion or a burning pain in the middle of the chest called heartburn. Heartburn happens when acids from your stomach flow backward into the esophagus. The esophagus is the tube that carries food from your throat to your stomach.
  • Pain caused by irritation of the stomach lining or ulcers. Food, bacteria, medicine, or too much stomach acid can cause irritation and ulcers. Ulcers are open sores that develop in the lining of the stomach. Antacids may also help keep the ulcer from getting worse.

How do they work?

Antacids lower the amount of acid in your stomach or block the effect of the acid. Some antacid products contain additional medicines, such as simethicone, which helps get rid of bloating and gas.

What else do I need to know about this medicine?

  • Try to get all of your prescriptions filled at the same place. Your pharmacist can help make sure that all of your medicines are safe to take together.
  • Many medicines have side effects. A side effect is a symptom or problem that is caused by the medicine. Ask your healthcare provider or pharmacist what side effects the medicine may cause and what you should do if you have side effects.
  • Follow the directions that come with your medicine, including information about food or alcohol. Make sure you know how and when to take your medicine. Do not take more or less than you are supposed to take.
  • Keep a list of your medicines with you. List all of the prescription medicines, nonprescription medicines, supplements, natural remedies, and vitamins that you take. Tell all healthcare providers who treat you about all of the products you are taking.

If you have any questions, ask your healthcare provider or pharmacist for more information. Keep all appointments for provider visits or tests.
