Omeprazole 20mg capsules are an effective, short-term treatment for symptoms such as indigestion, heartburn and acid reflux. Taken once daily, they help to reduce acid production in the stomach and provide reliable relief of symptoms.

Omeprazole 20mg capsules are used to treat gastro-oesophageal reflux disease (GORD). The symptoms of GORD include indigestion, reflux and heartburn. Omeprazole helps to treat these symptoms by reducing the acid production in the stomach and hence relieve symptoms of heartburn and indigestion that are caused by excess acid.

Omeprazole can be safely used in patients who have been diagnosed with GORD, indigestion, heartburn or reflux by their doctor where their symptoms are steady and have not worsened. Patients who are experiencing any of the symptoms for the first time or who have worsening symptoms should always be examined by their doctor to ensure any underlying causes are treated.

Take ONE Omeprazole 20mg capsule daily, usually in the morning.

Omeprazole can be taken with food and drink, or on an empty stomach - it does not matter.

If you forget to take a dose, take it as soon as you remember unless you are nearly due your next dose. You should never take a double dose.

Each capsule contains omeprazole 20mg as the active ingredient.

Other inactive ingredients that make up the complete product are: 

Pellets: sugar spheres (contain sucrose and maize starch), lactose anhydrous, hypromellose, hydroxypropylcellulose, sodium lauryl sulfate, disodium phosphate dodecahydrate, methacrylic acid – ethylacrylate copolymer (1:1) dispersion 30 per cent, macrogol 6000, talc.

Capsule Body: black iron oxide (E 172), red iron oxide (E 172), yellow iron oxide (E 172), titanium dioxide (E 171), gelatin.

Capsule Cap: indigo carmine (only omeprazole capsules 40 mg), red iron oxide (E 172), yellow iron oxide (E 172), titanium dioxide (E 171), gelatin.

Symptoms that seem like GORD (indigestion, nausea, heartburn & reflux) can also be signs of other underlying conditions that require treatment. See your doctor If you experience any of the following:

  • Significant weight loss for no reason.
  • Stomach pain
  • Problems swallowing
  • Unexplained vomiting (or vomiting that contains blood)
  • Passing black or blood-stained stools

If you are having any blood tests done it is important to let your doctor know that you are taking omeprazole as you may need to stop taking it before some tests.

Taking omeprazole for a sustained peroid of more than one year can cause a small increase in the risk of fractures of the hip, wrist and spine. If you suffer with osteoporosis or take corticosteroids, you should discuss this with your doctor.
