GENERIC NAME: NIZATIDINE - ORAL (nye-ZA-ti-deen)
BRAND NAME(S): Axid
USES: Nizatidine is used to treat ulcers of the stomach and intestines and prevent them from coming back after they have healed. This medication is also used to treat certain stomach and throat (esophagus) problems caused by too much stomach acid (e.g., erosive esophagitis) or a backward flow of stomach acid into the esophagus (acid reflux disease/GERD). Decreasing extra stomach acid can help relieve symptoms such as stomach pain, heartburn, difficulty swallowing, persistent cough, and trouble sleeping. It can also prevent serious acid damage to your digestive system (e.g., ulcers, cancer of the esophagus).Nizatidine belongs to a class of drugs commonly called H2 blockers. It works by reducing the amount of acid in your stomach.

If you are also taking antacids to relieve stomach pain as recommended by your doctor, you may take them at the same time as nizatidine.Take this medication regularly as prescribed in order to get the most benefit from it. To help you remember, take it at the same time(s) each day. Do not increase your dose or take it more often than directed.
