Omeprazole (
Prilosec®) is a prescription medicine licensed to treat gastric and duodenal ulcers,
H. pylori infections,
gastroesophageal reflux disease (
GERD), and pathological hypersecretory conditions. It comes in capsule form and is available in three different strengths, including:
- Omeprazole 10 mg
- Omeprazole 20 mg
- Omeprazole 40 mg.
The drug also comes in a non-prescription form. Over-the-counter omeprazole is approved for the treatment of frequent
heartburn. It comes in tablet form and is only available in a 20 mg strength.
For the treatment of duodenal ulcers and GERD (accompanied by erosive esophagitis), the recommended dosage is omeprazole 20 mg once daily for four to eight weeks. People with gastric ulcers typically take 40 mg for four to weight weeks.
The recommended
omeprazole OTC dosage for frequent heartburn is 20 mg once daily for up to 14 days every four months. It is not recommended to take non-prescription omeprazole long-term without talking with your healthcare provider first.
