- Treatment of active benign gastric ulcer
- Treatment and reduction of risk of NSAID-associated gastric ulcer
- Treatment of pathological hypersecretory conditions, including Zollinger-Ellison syndrome
Combination-therapy use

Contraindications of Omeprazole Magnesium
Omeprazole Magnesium is contraindicated in:
- Patients with known hypersensitivity to omeprazole, any component of the formulation, or any substituted benzimidazole (other proton pump inhibitors).

Frequently Asked Questions about Omeprazole Magnesium
What is Omeprazole Magnesium used for?
Omeprazole Magnesium is used to treat conditions caused by excess stomach acid, including GERD, erosive esophagitis, gastric and duodenal ulcers, NSAID-associated ulcers, and (with antibiotics) H. pylori infection.
How should I take Omeprazole Magnesium?
Omeprazole Magnesium should be swallowed whole with water, generally at least 1 hour before a meal, and should not be crushed or chewed since this destroys the coating that protects the medicine from stomach acid.
Can Omeprazole Magnesium be taken long-term?
Long-term use of Omeprazole Magnesium is associated with increased risk of bone fracture, low magnesium levels, vitamin B12 deficiency, and C. difficile-associated diarrhea. It should be used at the lowest effective dose for the shortest duration appropriate for the condition, and long-term use should be under a physician's supervision.
Is Omeprazole Magnesium safe during pregnancy?
Omeprazole Magnesium should be used in pregnancy only if clearly needed, after consulting a physician, since the potential benefit must be weighed against any potential risk to the fetus.
What should I avoid while taking Omeprazole Magnesium?
Patients taking Omeprazole Magnesium should avoid rilpivirine-containing HIV medicines, as this combination is contraindicated. Patients on clopidogrel should discuss alternatives with their physician, as Omeprazole Magnesium may reduce clopidogrel's effectiveness.
What if I miss a dose of Omeprazole Magnesium?
Take the missed dose of Omeprazole Magnesium as soon as remembered, unless it is almost time for the next dose, in which case skip the missed dose. Do not take a double dose to make up for a missed one.
