When choosing between omeprazole and Gaviscon for acid reflux, understanding how each treatment works can help you make an informed decision. Omeprazole is a proton pump inhibitor that reduces stomach acid production, whilst Gaviscon provides immediate symptom relief by forming a protective barrier. Both treatments have distinct benefits depending on your symptoms and treatment goals. This guide compares their effectiveness, uses, and suitability for different acid reflux conditions.

Omeprazole belongs to a class of medicines called proton pump inhibitors (PPIs). It works by blocking the enzyme system responsible for acid production in your stomach, providing sustained relief from acid reflux symptoms. Unlike antacids that neutralise existing acid, omeprazole prevents acid from being made in the first place. This makes it particularly effective for managing gastro-oesophageal reflux disease (GORD), frequent heartburn, and preventing acid-related damage to the oesophagus.
Gaviscon works differently by forming a protective raft on top of stomach contents, preventing acid from rising into the oesophagus. It also contains antacids that neutralise stomach acid on contact. This dual action provides rapid symptom relief, typically within minutes of taking the medicine. Gaviscon is particularly useful for occasional heartburn or when you need quick relief from acid reflux symptoms.
Studies show that omeprazole provides superior acid suppression compared to antacids like Gaviscon. A typical 20mg dose of omeprazole can reduce stomach acid production by up to 90% for 24 hours. This sustained acid reduction makes it highly effective for healing erosive oesophagitis and preventing complications of GORD. Gaviscon, whilst providing immediate relief, typically lasts 3-4 hours and doesn't reduce acid production.
Omeprazole may be more suitable if you experience frequent heartburn (more than twice weekly), have been diagnosed with GORD, or suffer from acid reflux that interferes with sleep or daily activities. It's also recommended for healing stomach or duodenal ulcers and preventing NSAID-induced ulcers. EverydayMeds offers omeprazole 20mg capsules and Losec MUPS tablets for those requiring branded options.
Gaviscon may be appropriate for occasional heartburn, mild acid reflux symptoms, or when you need immediate relief. It's often preferred by people who experience infrequent symptoms or those who want to avoid daily medication. Some individuals also use Gaviscon alongside PPIs for breakthrough symptoms.
Generic omeprazole typically offers excellent value for long-term acid reflux management. Whilst the daily cost may seem higher than occasional Gaviscon use, the sustained relief and prevention of complications often make it cost-effective for those with regular symptoms. EverydayMeds provides competitive pricing on both generic and branded omeprazole options.
If omeprazole isn't suitable, other PPIs are available including lansoprazole 15mg, pantoprazole 20mg, and esomeprazole tablets. For those preferring non-PPI options, famotidine tablets offer an H2 receptor antagonist alternative. Your healthcare provider can help determine the most appropriate treatment based on your specific symptoms and medical history.
