How does this medication work? What will it do for me?
Nizatidine belongs to the family of medications called H2-receptor antagonists. Nizatidine works by reducing the amount of acid secreted by the stomach. Reducing the acid helps to reduce the pain of stomach and intestinal ulcers and heartburn and assists in the healing of ulcers and damage caused by gastroesophageal reflux disease. Nizatidine is also used to prevent duodenal (intestinal) ulcers in certain circumstances.

The adult dose of nizatidine ranges depending on the condition being treated. For the treatment of stomach and intestinal ulcers, the usual dose is 300 mg daily (either 150 mg twice a day or 300 mg at bedtime). Ulcers usually heal within 4 weeks, but 8 weeks of treatment may be necessary.
To prevent the return of ulcers that have been healed, the usual dose is 150 mg daily at bedtime, for a period of 6 to 12 months, depending on the severity of the initial ulcer.
For gastroesophageal reflux disease, the usual dose is 150 mg twice a day.
Nizatidine may be taken with or without food, and swallowed with a full glass of water. Antacids may be used along with nizatidine if extra relief from excess acid is needed.
