What Zoton FasTabs is used for

Peptic Ulcers
Zoton FasTabs is used to treat peptic ulcers in adults. Depending on the position of the ulcer it is either 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 of the stomach.

Too much acid being made in the stomach can cause these ulcers.

Zoton FasTabs is also used to help stop duodenal ulcers from coming back.

Reflux Oesophagitis
Zoton FasTabs is used to treat the symptoms of reflux oesophagitis or reflux disease in adults and in children from 6 to 17 years of age. This can be caused by backflow (reflux) of food and acid from the stomach into the food pipe or gullet, also known as the oesophagus.

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

Heartburn and stomach pain associated with reflux or peptic ulcer.
Zoton FasTabs is used for the short-term treatment of heartburn and peptic ulcer symptoms in adults.

Peptic Ulcers Associated with Helicobacter Pylori Infection
Most people who have a peptic ulcer also have bacteria called Helicobacter pylori in their stomach. Zoton FasTabs can be taken in conjunction with certain antibiotics to help eradicate Helicobacter pylori and let your peptic ulcer heal. However, it is possible that the antibiotics may not always get rid of Helicobacter pylori.

How Zoton FasTabs works

Zoton FasTabs contains lansoprazole, which is a type of medicine called a proton pump inhibitor (PPI). It works by decreasing the amount of acid the stomach makes, to give relief from the symptoms of excessive acid and allow healing to take place. This does not stop food being digested in the normal way.

Ask your doctor if you have any questions about why Zoton FasTabs has been prescribed for you.

Your doctor may prescribe this medicine for another reason.

There is no evidence that Zoton FasTabs is habit-forming. This medicine is available only with a doctor’s prescription.

Before you take Zoton FasTabs

When you must not take it

Do not take Zoton FasTabs if you have an allergy to:

  • Lansoprazole
  • Any medicines containing a proton-pump inhibitor
  • Any of the ingredients listed at the end of this leaflet.

Some of the symptoms of an allergic reaction include:

  • rash, itching, or hives;
  • shortness of breath, wheezing or difficulty in breathing;
  • swelling of the face, lips, tongue or other parts of the body.

Do not take Zoton FasTabs if you have severe liver disease.

Do not take Zoton FasTabs if you are already taking the medicine atazanavir. Atazanavir is used to treat HIV infection. If it is taken at the same time as Zoton FasTabs, it will not be absorbed properly and will be less effective in treating HIV infection.

Do not take Zoton FasTabs after the use by (expiry) date printed on the pack or if the packaging is torn or shows signs of tampering. If it has expired or is damaged, return it to your pharmacist for disposal.

If you are not sure whether you should take this medicine, talk to your doctor.

How to take Zoton FasTabs

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

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

When to take it

Take Zoton FasTabs in the morning before food. Zoton FasTabs works best when taken on an empty stomach.

How much to take

Take one tablet each day, unless your doctor has told you otherwise.

The dose is usually 30 mg a day. The dose may vary from 15 mg to 30 mg a day depending on your condition.

Children (6 years or older)
For children between 6 to 11 years, the recommended dose depends on the weight of the child.

For children weighing 30 kg or less, the usual dose is 15 mg daily.

For children weighing over 30 kg, the usual dose is one 30 mg tablet daily.

For children between 12 to 17 years, the dose may vary from 15 mg to 30 mg a day depending on the condition.

How to take it

Swallow the tablet whole with a glass of water, or gently suck the tablet, then swallow the granules with your saliva. Do not chew or crush the tablet as this affects how well Zoton FasTabs works.

How long to take it

Keep taking Zoton FasTabs as directed, unless your doctor gives you other instructions.

In most patients, Zoton FasTabs relieves symptoms rapidly and healing is usually complete within 4 weeks. In some patients a further 4 weeks of treatment may be needed for complete healing.

In some cases, your doctor may decide that long-term treatment is needed.

Tell your doctor if any of your symptoms return after stopping long-term treatment.

Zoton FasTabs is recommended only for short-term use (8 to 12 weeks) in children.

For children aged 6-11 years, do not exceed 12 weeks of treatment with Zoton FasTabs.

For children aged 12-17 years, do not exceed 8 weeks of treatment with Zoton FasTabs.

Tell your doctor if your symptoms return. You may need further treatment.

If you forget to take it

If it is almost time for the next dose, skip the missed dose and take the next dose when you are meant to. Otherwise, take it as soon as you remember, and then go back to your normal routine.

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

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

If you take too much (overdose)

Immediately telephone your doctor or Poisons Information Centre (Tel 13 11 26) for advice, or go to Accident and Emergency at your nearest hospital, if you think that you or anyone else may have taken too much Zoton FasTabs. Do this even if there are no signs of discomfort or poisoning.

While you are taking Zoton FasTabs

Things you must do

Take Zoton FasTabs exactly as your doctor has prescribed.

Things you must not do

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

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

Things to be careful of

Be careful driving or operating machinery until you know how Zoton FasTabs affects you. Zoton FasTabs generally does not cause any problems with your ability to drive a car or operate machinery. However, as with many other medicines, Zoton FasTabs may cause dizziness in some people. Make sure you know how you react to Zoton FasTabs before you drive a car, operate machinery, or do anything else that could be dangerous if you are dizzy. If you drink alcohol, dizziness may be worse.

Things that may help your condition

Some self-help measures suggested below may help your condition. Talk to your doctor or pharmacist about these measures and for more information.

  • Alcohol
    Your doctor may advise you to limit your alcohol intake.
  • Aspirin and many other medicines used to treat arthritis, period pain or headaches
    These medicines may irritate the stomach and may make your condition worse. Your doctor or pharmacist may suggest other medicines you can take.
  • Caffeine
    Your doctor may advise you to limit the number of drinks that contain caffeine, such as coffee, tea, cocoa and cola drinks, because they contain ingredients that may irritate the stomach.
  • Eating habits
    Eat smaller, more frequent meals. Eat slowly and chew your food carefully. Try not to rush at meal times. Eat your meals well before bedtime.
  • Smoking
    Your doctor may advise you to stop smoking or at least cut down.
  • Weight
    Your doctor may suggest losing some weight to help your condition.

Side effects

Tell your doctor as soon as possible if you do not feel well while taking Zoton FasTabs.

All medicines can have side effects. Sometimes they are serious, most of the time they are not. You may need medical attention if you get some of the side effects.

Do not be alarmed by the list of side effects. You may not experience any of them.

  • Vomiting or nausea
  • Diarrhoea or constipation
  • Stomach pain
  • Indigestion
  • Flatulence or wind.

If you suffer from severe persistent diarrhoea and/or vomiting when taking Zoton FasTabs, tell your doctor.

Difficulty thinking or working because of:

  • Tiredness
  • Joint or muscle aches or pains
  • Generally feeling unwell
  • Feeling confused, depressed or having hallucinations.

Changes to your appearance such as:

Changes in your sight, hearing, taste or touch such as:

  • Frequent infections such as fever, severe chills, sore throat or mouth ulcers
  • Cramping of the muscles in your hands or feet
  • Irregular heartbeat
  • Fits or seizures.

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

Your doctor may want to take some blood tests from time to time to check your progress.

Tell your doctor if you notice anything making you feel unwell when taking, or soon after finishing taking, Zoton FasTabs.

Other side effects not listed above may occur in some patients.

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 occurring during treatment with Zoton FasTabs
  • You begin to vomit blood or food
  • You pass black (blood-stained) motions.

Ask your doctor or pharmacist if you do not understand anything in this list.

After taking Zoton FasTabs


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

Keep it in a cool dry place where the temperature stays below 25°C. Do not store it or any other medicines in a bathroom or near a sink. Do not leave it in the car or on windowsills. 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.
