Overview

Ometac 20mg Capsule contains Omeprazole 20mg and is available as a capsule. It is classified as a prescription medicine and may only be obtained with a valid prescription from a registered medical practitioner.

Only product, safety and handling information is published here. Anything beyond that is explained to you directly by your doctor or pharmacist as part of your consultation.

DoctorOnCall is a licensed online pharmacy. Orders for Ometac 20mg Capsule are processed only after a doctor has assessed your suitability and issued a prescription, and every order is checked by a registered pharmacist before it is sent out.

Directions for Use

Take Ometac 20mg Capsule once daily, preferably in the morning before a meal, at about the same time each day. Swallow the capsule whole with a glass of water – do not chew, crush, or open the capsule, as this protects the enteric-coated pellets inside from being broken down by stomach acid before the medicine reaches the small intestine where it is absorbed.

Dosage

The usual dose of Ometac 20mg Capsule is 20mg once daily for GERD and maintenance therapy, though your doctor may prescribe up to 40mg daily or twice daily for more severe conditions such as active ulcers or H. pylori eradication (usually combined with antibiotics for 7-14 days). Treatment duration depends on the condition being treated and will be advised by your doctor.

Storage Instructions

Store below 30°C in a dry place, away from direct sunlight and out of reach of children.

Side Effects

  • Headache
  • Nausea or vomiting
  • Stomach pain
  • Diarrhea or constipation
  • Bloating or gas
  • Dizziness
  • Fatigue

Contraindications

  • Known hypersensitivity to omeprazole or other substituted benzimidazoles
  • Concomitant use with rilpivirine-containing HIV medicines

Drug / Food Interactions

  • Clopidogrel’s antiplatelet effect may be reduced, as omeprazole inhibits the CYP2C19 enzyme needed to activate it
  • Methotrexate levels and toxicity may increase, especially at high-dose methotrexate regimens
  • Warfarin’s blood-thinning effect may be enhanced, requiring closer INR monitoring
  • Ketoconazole and itraconazole absorption may be reduced due to decreased stomach acidity

Quick Tips

  • Take this medicine before a meal, ideally in the morning, for the best acid-suppressing effect
  • Continue the full course if prescribed for ulcer healing or H. pylori eradication, even after symptoms improve
  • Report persistent diarrhoea, unusual muscle cramps, or new bone pain to your doctor, especially with long-term use
  • Avoid unnecessary long-term use without medical review, as prolonged high-dose therapy carries additional risks

Ingredients / Active Ingredients

  • Omeprazole 20mg
