What is Mylanta Tonight?

Calcium and magnesium are naturally occurring minerals that are sometimes used as antacids to relieve heartburn, acid indigestion, and upset stomach. Simethicone allows gas bubbles in the stomach and intestines to come together more easily.

Mylanta Tonight is a combination antacid, anti-gas medicine used to treat heartburn, indigestion, gas and bloating, or stomach discomfort caused by overeating.

Mylanta Tonight may also be used for purposes not listed in this medication guide.
