What is Omeprazole?

Omeprazole is a treatment for GORD, a digestive condition of recurring acid reflux. Acid reflux happens 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 and acid lingering in the oesophagus. It can cause a range of symptoms.

Omeprazole is a generic treatment that can reduce symptoms of heartburn, help with GORD or treat gastric and duodenal ulcers. 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.

How does Omeprazole work?

The active ingredient in Omeprazole works tiny membranes called proton pumps in the wall of the stomach. Proton pumps make and release the acids which break down food. With GORD you have too much of this acid, causing discomfort.

Omeprazole stifles the action of the proton pumps, reducing the amount of stomach acid produced. This helps the symptoms of GORD.

What doses of Omeprazole are there?

Omeprazole comes in both tablets and capsules. There are doses of 10mg, 20mg and 40mg. The oral suspension fluid comes in doses of 2mg/ml and 4mg/ml.

The dose will depend on how uncomfortable your symptoms are and treatment usually lasts for 4 weeks. If it’s an ongoing problem, treatment might last longer.

How to take Omeprazole

You should use Omeprazole exactly as told by your clinician. Depending on the version of Omeprazole there’s a slight difference in how you take it.

Instructions: Omeprazole capsules & tablets:

  • Take one capsule or tablet daily in the morning.
  • Swallow whole without chewing.
  • You can take Omeprazole tablets or capsules with or without food.

Instructions: Omeprazole oral suspension fluid:

  • Take your dose daily in the morning.
  • Take it on an empty stomach or half an hour before your meal.

How long does it take Omeprazole to work?

One Omeprazole daily dose provides quick and effective reduction in acid production in the stomach. If taken as directed, its full effect can be seen in 4 days.

Clinical trials showed that with a single 24 hr 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 it at the same time as food wasn’t observed to slow it down.

What should I do if I make a mistake when using Omeprazole?

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, consult your doctor right away.

FAQ: Omeprazole

Have something specific you want to know? Search our info below, or ask our experts a question if you can’t find what you’re looking for.

How is Omeprazole different to other treatments for GORD?

There are other treatments for GORD available in the market, but not all treatments come as an oral solution. This can be good if you don’t like taking tablets or capsules.

Omeprazole is also a generic treatment, which means it’s usually less expensive than other branded treatments. It’s a cheaper option if you’re looking to try out some treatments for GORD.

Is Omeprazole similar to any other treatments?

Acid reflux treatments tend to be proton pump inhibitors, so they often work similarly. They can contain different active ingredients though, so you can try a few different ones if one doesn’t work for you.

Losec is the branded form of Omeprazole. This means it contains the same active ingredient, but it will cost you more. They should work in the same way.

Which dose of Omeprazole should I use?

Your Omeprazole dose depends on what it’s treating and also the severity of symptoms. The dose for treating ulcers will be different from that of treating acid reflux. Treating ulcers may require you to take a higher dose for a shorter period of time. When treating acid reflux you often need a lower dose for longer periods.

Similarly, the dose varies when you take it for prevention instead of treatment. For treating acid reflux you’ll need to take a dose for 4-8 weeks but for preventing acid reflux you’ll be taking Omeprazole for a longer time.

If you try a low dose of Omeprazole for GORD and find you’re still struggling, you talk to a clinician about raising your dosage until you feel relief.

How effective is Omeprazole?

Numerous clinical trials have shown that Omeprazole is effective in providing early and sustained reduction in heartburn as well as treatment of other symptoms caused by GORD.

In patients taking a daily dose of Omeprazole there was no heartburn in:

  • 62% cases by day 7

  • 74% cases by day 27

Another study showed that 86% of patients suffering with severe swelling of the food pipe (esophagitis) healed within 12 weeks of using 40mg Omeprazole.

Do I need a prescription for Omeprazole?

Omeprazole can be ordered without a prescription in low doses, for a short period of time. If you want to order a higher dose or a longer treatment time for Omeprazole, you will need a prescription. This is just to make sure the treatment is the best one for you.
