Omeprazol is omeprazole, known elsewhere as Losec or Prilosec. It reduces stomach acid.
- What it is used for: reflux and heartburn, stomach or duodenal ulcers, treating Helicobacter pylori together with antibiotics, and protecting the stomach in at-risk people who take anti-inflammatories.
- How to take it: before breakfast, as directed on the pack or by your doctor.
- Long-term use: it can lower vitamin B12 and magnesium, so the need for it should be reviewed from time to time.
- Do you need a prescription? Small packs for occasional heartburn are sold without one; larger packs need a prescription. See omeprazole in Spain: over the counter or prescription for the details.
- See a doctor if: you have difficulty swallowing, weight loss, repeated vomiting, black stools or symptoms that do not settle.
