Antacids help to treat heartburn (indigestion). They work by changing the stomach acid that causes your 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 as well, but they can cause different side effects. If you use antacids often and have problems with side effects, talk with your doctor.
Heartburn - self-care
When to Use Antacids
Antacids are a good treatment for heartburn that does not happen very often. Take antacids about 1 hour after eating or at the time heartburn usually happens after you eat. If you are taking them for symptoms at night, do NOT take them with food.
