Prilosec is used for treating heartburn or irritation of the esophagus caused by gastroesophageal reflux disease (GERD). It may also be used for short-term treatment of ulcers of the stomach or small intestines. It may also be used with certain antibiotics to treat ulcers of the small intestines and to help prevent them from coming back. It may also be used to treat conditions that cause your body to make too much stomach acid (eg, Zollinger-Ellison syndrome). Prilosec is a proton pump inhibitor (PPI). It works by decreasing the amount of acid produced in the stomach.
Use Prilosec as directed by your doctor.
- Take Prilosec by mouth on an empty stomach before eating.

- If you have trouble swallowing the capsule, add 1 tablespoon of applesauce to an empty bowl. Open the capsule and empty the pellets onto the applesauce.
