Omeprazole (Prilosec®) is a medication often used for treating gastroesophageal reflux disease (GERD), certain ulcers (duodenal and gastric), and pathological hypersecretory conditions.
The prescription version of omeprazole comes in capsule form or as packets to be mixed to make an oral suspension (liquid). Prescription omeprazole capsules are available in three strengths, including 10 mg, 20 mg, and 40 mg. The medicine is typically taken once or twice a day.
If needed (for people who have trouble swallowing capsules whole), the capsules can be opened and the contents sprinkled onto a spoonful of applesauce.
The medication is a type of proton pump inhibitor that works by binding to the tiny pumps in the stomach that produce acid, to decrease acid production. While most people tolerate omeprazole well, potential side effects include abdominal pain, upper respiratory infections, and hair loss.
