What PEMZO is used for

Reflux Oesophagitis

PEMZO is used to treat the symptoms of reflux oesophagitis or reflux disease. This can be caused by "washing back" (reflux) of food and acid from the stomach into the food pipe (oesophagus).

Reflux can cause a burning sensation in the chest rising up to the throat, also known as heartburn.

PEMZO is also taken to help stop reflux oesophagitis coming back or relapsing.

Peptic Ulcers

PEMZO is used to treat peptic ulcers. Depending on the position of the ulcer it is called a gastric or duodenal ulcer. A gastric ulcer occurs in the stomach. A duodenal ulcer occurs in the duodenum which is the tube leading out from the stomach.

These ulcers can be caused by too much acid being made in the stomach.

PEMZO is also used to help stop gastric or duodenal ulcers coming back.

Peptic Ulcers Associated with Helicobacter pylori Infection

Most people who have a peptic ulcer also have a bacterium called Helicobacter pylori in their stomach.

When PEMZO is taken with antibiotics, they work to kill the bacterium and let your ulcer heal. You may need further treatment with antibiotics.

Peptic Ulcers Associated with Non-steroidal Anti-Inflammatory Drugs (NSAIDs)

Some peptic ulcers are caused by taking medicines called non-steroidal anti-inflammatory drugs (NSAIDs), a type of medicine used to treat pain or inflammation. PEMZO is also used to heal and prevent ulcers associated with NSAIDs.

Zollinger-Ellison Syndrome

PEMZO is also used to treat a rare condition called Zollinger-Ellison syndrome, where the stomach produces large amounts of acid, much more than in ulcers or reflux disease.

How PEMZO Works

PEMZO is a type of medicine called a proton-pump inhibitor. It works by decreasing the amount of acid made by the stomach, to give relief of symptoms and allow healing to take place. This does not stop food being digested in the normal way.

Follow all directions given to you by your doctor carefully. They may differ from the information contained in this leaflet.

Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may prescribe this medicine for another reason.

There is no evidence that PEMZO is addictive.

This medicine is only available on prescription.

If you do not understand the instructions on the pack, ask your doctor or pharmacist for help.

How much to take

The dose for PEMZO varies from patient to patient. Your doctor will decide the right dose for you.

How to take it

Swallow the capsules with a glass of water.

Do not crush or chew the capsules.

If the granules or pellets contained in the capsules are crushed or chewed, they will not work properly.

When to take it

Take each dose of PEMZO at about the same time each day.

Taking each dose of PEMZO at the same time each day will help you remember when to take it. PEMZO can be taken with food or on an empty stomach.

How long to take it

Keep taking PEMZO for as long as your doctor recommends.

If you are taking PEMZO to heal an ulcer or to treat reflux disease, you will usually need to take PEMZO for 4 to 8 weeks.

It is very important that you take the full course of PEMZO as prescribed by your doctor so that your condition is properly treated.

If you are taking PEMZO to stop an ulcer from coming back or to treat other conditions, your doctor will tell you how long you need to take the capsules.

If you forget to take it

If you forget to take a dose, take it as soon as you remember, and then go back to taking it as you would normally.

If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to.

Do not take a double dose to make up for the dose that you missed.

If you have trouble remembering when to take your medicine, ask your pharmacist for some hints.

If you take too much (Overdose)

Telephone your doctor or the Poisons Information Centre (13 11 26) or go to Accident and Emergency at your nearest hospital immediately if you think that you or anyone else may have taken too much PEMZO even if there are no signs of discomfort or poisoning.

While you are taking PEMZO

Things you must do:

Take PEMZO exactly as your doctor has prescribed.

If you are about to start any new medicine, remind your doctor and pharmacist that you are taking PEMZO.

Tell all doctors, dentists and pharmacists who are treating you that you are taking PEMZO.

Tell your doctor if you become pregnant while you are taking PEMZO.

Tell your doctor if your symptoms return. Although PEMZO can heal ulcers successfully, it may not prevent them recurring at a later date.

Things you must not do

Do not take PEMZO to treat any other complaints unless your doctor tells you to.

Do not give your medicine to anyone else, even if they have the same condition as you.

Do not stop taking your medicine or change the dosage without checking with your doctor. If you stop taking it suddenly or change the dose, your condition may worsen or you may have unwanted side effects.

Side effects

Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking PEMZO. All medicines can have side effects. Sometimes they are serious, most of the time they are not. You may need medical treatment if you get some of the side effects.

Ask your doctor or pharmacist to answer any questions you may have.

Tell your doctor if you notice any of the following and they worry you:

  • constipation
  • nausea
  • diarrhoea
  • headache
  • skin rash

These side effects are usually mild.

Tell your doctor immediately if you notice any of the following:

  • muscle pain or weakness
  • dizziness
  • "pins and needles"
  • changes in sleep patterns
  • mood changes
  • increase in breast size (males)
  • fever
  • increased bruising
  • signs of liver inflammation including yellowing of the skin or eyes, feeling generally unwell, nausea, vomiting, loss of appetite.

These are serious side effects that may require medical attention. Serious side effects are rare.

If any of the following happen, tell your doctor immediately or go to Accident and Emergency at your nearest hospital.

  • swelling of the face, lips, mouth, tongue or throat which may cause difficulty in breathing
  • shortness of breath or difficulty in breathing
  • skin reaction which may include rash, itching, redness, blistering or peeling of the skin
  • ulcers, blisters or bleeding of the lips, eyes, mouth, nose and genitals
  • swelling of feet, hands and ankles

These are very serious side effects. You may need urgent medical attention or hospitalisation. These side effects are rare.

Tell your doctor or pharmacist if you notice anything that is making you feel unwell. Other side effects not listed above may occur in some people.

Other problems are more likely to arise from the ulcer itself rather than the treatment.

For this reason, contact your doctor immediately if you notice any of the following:

  • pain or indigestion that occurs during treatment with PEMZO
  • you begin to vomit blood or food
  • you pass black (blood-stained) motions.

After using it


Keep your PEMZO in the blister pack until it is time to take them. If you take PEMZO out of the blister pack they will not keep well.

Keep it in a cool, dry place where the temperature stays below 25 °C.

Do not store it or any other medicine in the bathroom or near a sink. Do not leave it on a window sill or in the car. Heat and dampness can destroy some medicines.

Keep it where young children cannot reach it. A locked cupboard at least one-and-a-half metres above the ground is a good place to store medicines.


If your doctor tells you to stop taking PEMZO or the capsules have passed their expiry date, ask your pharmacist what to do with any tablets you have left over.
