What is Axid?
Axid is a histamine-2 blocker that works by decreasing the amount of acid produced by the stomach.
Axid is used to treat ulcers in the stomach and intestines. This medicine also treats heartburn and erosive esophagitis caused by gastroesophageal reflux disease (GERD), a condition in which acid backs up from the stomach into the esophagus.
Axid may also be used for purposes not listed in this medication guide.
Follow all directions on your medicine label and package. Tell each of your healthcare providers about all your medical conditions, allergies, and all medicines you use.
