Acid rebound

Acid rebound

In some people who use acid-reducing medicines for heartburn, ulcers, or gastroesophageal reflux disease (GERD), stopping the medicine causes the stomach to produce even more acid. This can make symptoms worse for a while. This is called acid rebound.

If you take acid reducer medicine (such as an H2 blocker or a proton pump inhibitor) every day to prevent heartburn, do not stop taking the medicine suddenly. By taking less and less medicine over time (called tapering), you may be able to prevent acid rebound.
