What is nizatidine 150 mg capsules used for?
Nizatidine 150 mg capsules are used to help reduce stomach acid. In the original content, they are described as being used for:
- Duodenal ulcers
- Benign gastric ulcers
- Gastroesophageal reflux disease (GERD)

As an H2-receptor antagonist, nizatidine works by blocking histamine activity at the stomach’s parietal cells, which lowers acid production. This can help relieve symptoms such as heartburn, cough, and stomach pain when these are linked to excess acid.

Swallowing the capsule with a full glass of water may help it go down more easily.
