About Omeprazole

Omeprazole is a drug that reduces the amount of acid the stomach makes. It is a proton pump inhibitor (PPI). It can be used to treat a number of conditions. It is most often used to treat indigestion and heartburn/acid reflux.

Acid reflux, also known as heartburn, occurs when stomach acid travels up the gullet (oesophagus) to the throat. This can cause a burning sensation in the chest and leave an unpleasant taste in the back of the mouth. If acid reflux continues long term, it is called gastroesophageal reflux disease (GERD or GORD).

Indigestion, also called dyspepsia, is discomfort in the stomach that can cause you to feel bloated or sick. Acid reflux is also a symptom of indigestion.

Omeprazole is very commonly used to treat these conditions and is effective at improving symptoms of heartburn and indigestion.

Acid reflux can sometimes be caused by serious diseases. Please see your GP if:

  • Lifestyle changes or over the counter medicines do not improve symptoms
  • Symptoms persist longer than 5 days despite taking omeprazole
  • You have heartburn frequently for 3 weeks or more
  • There are other symptoms, like food getting stuck in the throat, being sick often or unintended weight loss

Your GP can run tests to rule out serious causes of acid reflux.

When filling out our online form make sure to list all of your symptoms, even if they do not seem linked to acid reflux.

Omeprazole can also be used for:

  • Erosive esophagitis (stomach acid can damage the oesophagus long term)
  • Zollinger ellison syndrome
  • Stomach ulcers
  • H.Pylori stomach infections (omeprazole is taken for 7 or 14 days alongside antibiotics)

Certain factors can cause or worsen acid reflux and indigestion:

  • Fatty, rich or spicy foods
  • Caffeinated drinks, such as coffee or fizzy drinks
  • Alcohol
  • Being overweight
  • Smoking
  • Stress
  • Certain medications, such as ibuprofen

How does omeprazole work?

The lining of the stomach contains proton pumps. These pump acid into the stomach to help digest food. Acid reflux is caused by this acid travelling from the stomach to the gullet and sometimes to the throat.

Omeprazole is a proton pump inhibitor. This means it stops the proton pumps producing acid. This reduces the amount of acid in the stomach and improves indigestion and heartburn symptoms.

Omeprazole is very effective at reducing the amount of acid produced by the stomach. This makes it an effective treatment for acid reflux.

Omeprazole capsules are delayed release to make sure the medication enters the bloodstream.

Omeprazole capsules are available in strengths of 10mg or 20mg. Our doctors can also prescribe orodispersible versions of omeprazole under the brand name Losec MUPS. It can also come as an oral suspension. These are useful if a patient has difficulty swallowing capsules.

Omeprazole Alternatives

There are several other prescription and non-prescription treatments for acid reflux. The other most common prescription treatments are:

Over the counter treatments for acid reflux work by creating a barrier on top of the stomach to prevent acid reflux. These treatments include:

Certain lifestyle changes can be used alongside omeprazole or other medications to improve symptoms: 

  • Avoid eating 3 hours before bedtime
  • Eating smaller meals
  • Losing weight if overweight
  • Raising the head of the bed (so your chest is above the level of your waist)

    Antacids like Gaviscon can be used with omeprazole but should be taken at least 2 hours after omeprazole.
