Omeprazole is a proton pump inhibitor used in the treatment of heartburn, gastroesophageal reflux disease (acid reflux), and peptic ulcer disease. The medicine helps reduce stomach acid by blocking the actions of an enzyme (H+/K+ ATPase or gastric proton pump). This proton pump lies in the stomach wall cells and is responsible for releasing gastric acid secretion. Omeprazole prevents the release of stomach acid and relieves symptoms of food pipe lining inflammation (esophagitis), gastroesophageal reflux disease (GERD), or heartburn. Complete the full course of the medicine and do not abruptly stop taking the medicine.

Take the medicine as per the dosage and duration prescribed by the doctor. Do not crush, chew or break the tablets. Some people may experience side effects such as stomach pain, gas formation (flatulence), nausea, vomiting, diarrhea, and headache. Avoid using Omeprazole Capsules if you are suffering from St John’s Wort (plant-based antidepressant), rifampin (antibiotic), and methotrexate (anti-cancer and anti-arthritis medicine) due to the severe drug interaction.
