Omeprazole Dosage Strengths and Prescription Requirements

Reviewed by Mostafa Damghani · 03/07/2026

Over-the-Counter Omeprazole Availability

You can buy omeprazole 10mg tablets over the counter at pharmacies for treating occasional heartburn and acid reflux symptoms. This lower strength is suitable for short-term use up to 4 weeks. However, the more commonly prescribed 20mg omeprazole capsules require a prescription or online consultation with a registered prescriber.

Prescription Omeprazole Strengths at EverydayMeds

EverydayMeds stocks omeprazole 20mg capsules, the standard prescription strength for treating gastro-oesophageal reflux disease (GORD) and stomach ulcers. We also offer Losec MUPS 20mg tablets, which are branded omeprazole tablets that dissolve easily for patients who have difficulty swallowing capsules. Both products contain the same active ingredient but in different formulations.

Alternative PPI Options

If omeprazole is not suitable, EverydayMeds provides several alternative proton pump inhibitors. Lansoprazole 15mg capsules work similarly to omeprazole and may be preferred by some patients. Pantoprazole 20mg tablets offer another effective option, whilst esomeprazole tablets provide a modified form of omeprazole that may work better for certain individuals.

How Our Online Consultation Works

To access prescription-strength omeprazole through EverydayMeds, complete our confidential online consultation. Our registered pharmacist prescribers will review your symptoms, medical history, and current medications to determine if omeprazole 20mg is appropriate for your acid reflux treatment. The consultation typically takes 24-48 hours to process, followed by discreet home delivery.

Dosage Guidelines for Different Conditions

The standard dose for GORD treatment is omeprazole 20mg once daily, usually taken in the morning before food. For stomach ulcer treatment, the same 20mg daily dose is typically prescribed for 4-8 weeks. Some patients with severe symptoms may require omeprazole 40mg daily, but this higher dose requires careful medical supervision and regular review.
