How Omeprazole and Gaviscon Work Differently
Omeprazole belongs to a class of medicines called proton pump inhibitors (PPIs). It works by blocking the enzyme system responsible for stomach acid production, providing sustained relief that can last up to 24 hours. This makes omeprazole particularly effective for people experiencing frequent heartburn or gastro-oesophageal reflux disease (GORD). The reduction in acid production allows damaged oesophageal tissue to heal whilst preventing further irritation.
Gaviscon, by contrast, is an alginate-based antacid that works through neutralisation and physical barrier formation. When taken after meals, it forms a protective foam layer that sits on top of stomach contents, helping to prevent acid reflux into the oesophagus. This provides rapid relief but typically lasts 3-4 hours, making it suitable for occasional symptoms or as additional relief alongside other treatments.
Choosing the Right Treatment for Your Symptoms
For occasional heartburn occurring less than twice weekly, Gaviscon may provide adequate relief. Its rapid action makes it convenient for immediate symptom management after meals or at bedtime. However, if you experience heartburn more than twice weekly, or symptoms that interfere with daily activities, omeprazole over the counter may be more appropriate.
EverydayMeds stocks Omeprazole 20mg capsules, the most commonly prescribed PPI strength, alongside branded Losec MUPS 20mg tablets. Our range also includes alternative PPIs such as Lansoprazole 15mg and Pantoprazole 20mg for those who may require different formulations or have specific sensitivities.
Prescription vs Over-the-Counter Options
Omeprazole is available over the counter for short-term use (maximum 2 weeks without medical supervision) or through prescription for longer-term management. Our online consultation service allows you to obtain a prescription conveniently, with qualified prescribers reviewing your symptoms and medical history to recommend the most suitable treatment duration and strength.
For persistent symptoms lasting more than two weeks, prescription-strength treatment is often more appropriate. This allows for proper monitoring and dose adjustment if needed. EverydayMeds offers discreet packaging and next-day delivery throughout the UK, making it convenient to maintain consistent treatment.
Cost Comparison and Value
When comparing costs, consider both price per dose and treatment duration. Whilst Gaviscon may appear less expensive initially, omeprazole's longer duration of action often provides better value for frequent sufferers. A month's supply of omeprazole typically costs less than using Gaviscon multiple times daily for the same period.
Our competitive pricing on all PPI medications, combined with prescription consultation services, offers excellent value for comprehensive acid reflux management. We also stock generic alternatives that provide the same active ingredients as branded versions at reduced cost.
