Drug Name
Prilosec (Omeprazole)

Drug Uses
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). It may also be used for other conditions as determined by your doctor.

How to use
Use Prilosec as directed by your doctor. Check the label on the medicine for exact dosing instructions.

• Take Prilosec by mouth on an empty stomach before eating.
• Swallow Prilosec whole. Do not break, crush, chew, or open Prilosec before swallowing.
• 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. Mix the pellets with the applesauce and swallow the mixture at once, followed by a glass of cool water. The applesauce used should not be hot and should be soft enough to be swallowed with out chewing. Do not chew or crush the pellets. Do not store the mixture for further use.
• You may take antacids while you are using Prilosec, if you are directed to do so by your doctor.
• If you also take an imidazole antifungal (eg, ketoconazole), take it at least 2 hours before taking Prilosec.
• If you also take sucralfate, take Prilosec at least 30 minutes before taking sucralfate.
• Continue to take Prilosec even if you feel well. Do not miss any doses.
