What is nizatidine (Axid, Axid AR, Axid Pulvules)?

Nizatidine is in a group of drugs called histamine-2 blockers. Nizatidine works by decreasing the amount of acid the stomach produces.

You should not use this medication if you are allergic to nizatidine or similar medications such as ranitidine (Zantac), cimetidine (Tagamet), or famotidine (Pepcid).

Before taking nizatidine, tell your doctor if you have kidney or liver disease, or stomach cancer or other problems.
