Antacids help to treat heartburn (indigestion). They work by changing the stomach acid that causes heartburn.
You can buy many antacids without a prescription. Liquid forms work faster, but you may like tablets because they are easy to use.
All antacids work equally well, but they can cause different side effects. If you use antacids often and have problems with side effects, talk with your health care provider.
Heartburn - self-care
When to Use Antacids
Antacids are a good treatment for heartburn that occurs once in awhile. Take antacids about 1 hour after eating or when you have heartburn. If you are taking them for symptoms at night, DO NOT take them with food.
