Omeprazole is a generic treatment for Gastro-Oesophageal Reflux Disease (GORD) or acid reflux. It can treat the symptoms of GORD, help control acid reflux, and prevent it in the future.
We can help you choose an acid reflux treatment that suits you best. Chat to our trained clinicians online and we’ll give you tailored recommendations – and we’ll deliver it to your door.
Omeprazole is a heartburn medication used to treat recurring acid reflux, alongside a range of other conditions. Acid reflux is when stomach acid or bile rises up the food pipe lining and causes irritation and heartburn.
GORD can be caused by a combination of things. It’s often linked to the bundle of muscles between your stomach and oesophagus losing strength. It’s also associated with more pressure caused by straining and coughing, food staying in the stomach for longer, excess acid in your stomach and stomach acid lingering in the oesophagus. It can cause a range of symptoms, like stomach pain.
Omeprazole is the active ingredient and generic name of Losec. It comes as a gastro-resistant capsule, as a tablet or as an oral suspension fluid.
This page focuses on how Omeprazole works to treat GORD, which is the main condition it’s used to treat.
But Omeprazole is a generic medication that can also be used to:
Omeprazole is a type of treatment called a proton pump inhibitor. This means the active ingredient in Omeprazole works on tiny membranes called proton pumps in the stomach lining. Proton pumps make and release the acid that breaks down food. If you have GORD your stomach produces too much acid, which causes discomfort.
Taking Omeprazole, like any other proton pump inhibitors, will stifle the action of your proton pumps, reducing the amount of acid your stomach produces. This helps to relieve symptoms of GORD and prevent acid reflux.
Omeprazole comes in both tablets and capsules. Omeprazole capsules and tablets come in doses of 10mg, 20mg and 40mg. There’s also an oral suspension fluid that comes in doses of 2mg/ml and 4mg/ml.
Your Omeprazole dosage will depend on why you're taking it and how uncomfortable your symptoms are, but treatment usually lasts four weeks and your usual starting dose will be low. If it’s an ongoing problem, you might need to take Omeprazole for longer.
Your Omeprazole dose depends on what it’s used to treat and also the severity of your symptoms. The dose to treat stomach ulcers will be different from the one for treating acid reflux.
The dose also varies when you take it for prevention instead of treatment.
For more info on treatment dosage and duration for your symptoms and needs, check the patient information leaflet that comes with your medicine. Or alternatively, ask your doctor or pharmacist.
If you’ve been taking a low dose of Omeprazole for GORD and find you’re still struggling, talk to a clinician about raising your dosage.
How we source info.
When we present you with stats, data, opinion or a consensus, we’ll tell you where this came from. And we’ll only present data as clinically reliable if it’s come from a reputable source, such as a state or government-funded health body, a peer-reviewed medical journal, or a recognised analytics or data body. Read more in our editorial policy.
You should use Omeprazole exactly as told by your clinician. There’s a slight difference in how you take Omeprazole depending on the type you’re using.
The following guidance is for how to take Omeprazole for GORD. If you’re using Omeprazole to treat other conditions or symptoms, the instructions may differ. Check the patient information leaflet or speak to your doctor or pharmacist for more info.
One Omeprazole daily dose provides a quick and effective reduction in the amount of acid your stomach produces. If taken as directed, its full effect can be seen in four days.
Clinical trials showed that with a single 24 hour dose there is a 70% reduction in acid production and an 80% reduction in the acidity level. It takes about 1-2 hours to reach peak presence in the bloodstream. Taking Omeprazole at the same time as food wasn’t observed to slow it down.
It’s best to take Omeprazole in the morning. This means it’ll be working throughout the day, when you need it most. If you need to take two doses per day, take one in the morning and one in the evening.
If you forget to take your dose, take it when you remember. If it’s almost time for your next dose, skip the missed dose. Don’t take a double dose to make up for the missed one.
If you take more than the recommended dose, speak to your doctor immediately.
