What Ondansetron ODT Lupin is used for

Ondansetron ODT Lupin orally disintegrating tablets is used to treat the nausea and vomiting for which they have been prescribed.

It belongs to a group of medicines called antiemetics.

This medicine works by helping to stop the nausea (sick feeling) and vomiting which can occur after certain treatments. This is a special type of tablet which dissolves in a few seconds when placed on the tongue. It is easier to swallow than ordinary tablets.

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

This medicine is available only with a doctor’s prescription.

This medicine is not addictive.

Use in children

There is not enough information to recommend the use of ondansetron for children under the age of 4 years. An appropriate dosage form should be used for the child.

How to take Ondansetron ODT Lupin

Follow all directions given to you by your doctor or pharmacist carefully. They 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.

How much to take

Your doctor will tell you how much of this medicine you should take. This will depend on your condition and whether you are taking any other medicines.

Do not take more than your doctor tells you.

If you vomit within one hour of taking your first medicine dose of each course prescribed for you, you should take the same dose again. If you continue to vomit, tell your doctor.

Do not stop taking your medicine or change your dosage without first checking with your doctor.

How to take it

Peel back the foil top of the blister strip and gently remove the tablet. (DO NOT try to push it through the foil top as the tablet is fragile and may break up inside the foil).

Place the tablet on top of your tongue. It will disappear very quickly, then swallow as normal.

When to take it

Your doctor will be able to tell you when you should take this medicine.

How long to take it

Your doctor or pharmacist will be able to tell you how long you should take your medication.

If you forget to take it

If you miss your dose and you do not feel sick take your next dose when you are meant to.

If you miss your dose, and you feel sick, take the missed dose as soon as possible, then go back to taking your medication 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.

If you take too much (overdose)

If you think that you or anyone else may have taken too much of this medicine, immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26) for advice.

Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.

Symptoms of an overdose may include visual disturbances, severe constipation and hypotension.

While you are taking Ondansetron ODT Lupin

Things you must do

If you are about to be started on any new medicine, remind your doctor and pharmacist that you are taking this one.

Tell any other doctors, dentists, and pharmacists who treat you that you are taking this medicine.

Tell your doctor if, for any reason, you have not taken your medicine exactly as prescribed.

Otherwise, your doctor may think that it was not effective and change your treatment unnecessarily.

If you are going to have surgery, tell the surgeon or anaesthetist that you are taking this medicine.

If you become pregnant or plan to breastfeed while taking this medicine, tell your doctor immediately.

If you are about to have any blood tests, tell your doctor that you are taking this medicine.

Keep all of your doctor’s appointments so that your progress can be checked. Your doctor may do some tests from time to time to make sure the medicine is working and to prevent unwanted side effects.

Things you must not do

Do not take this medicine 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 lower the dosage without checking with your doctor. If you stop taking it suddenly, your condition may worsen or you may have unwanted side effects. If possible, your doctor will gradually reduce the amount you take each day before stopping the medicine completely.

Things to be careful of

Be careful driving or operating machinery until you know how this medicine affects you. This medicine may cause dizziness, light-headedness and drowsiness in some people. If you have any of these symptoms, do not drive, operate machinery or do anything else that could be dangerous.

Side effects

Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking this medicine.

Ondansetron helps most people but it may have unwanted side effects in a few people. 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 following lists of side effects. You may not experience any of them.

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

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

  • Headache
  • A sensation of warmth or flushing
  • Mild stomach cramps
  • Constipation or diarrhoea
  • Dry mouth
  • Hiccups
  • Dizziness or light-headed feeling

The above list includes the more common side effects of your medicine. They are usually mild and short-lived.

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

  • chest pain or tightness of chest
  • changes in the way your heart beats e.g. if you notice it beating faster or slower than normal, or if it beats irregularly or if it ‘throbs’
  • disturbance in heart rhythm (sometimes causing a sudden loss of consciousness)
  • low blood pressure
  • abnormal muscular body movements or shaking
  • involuntary upward movement of the eyes
  • unusual muscle tone causing distortion of the body
  • fits or convulsions
  • patients may experience “serotonin syndrome” (confusion, sweating, unsteadiness, shaking, diarrhoea) when ondansetron is taken in combination with other serotonergic drugs. Serotonergic drugs can include certain types of antidepressants, opioid pain medicines such as tramadol and fentanyl, and lithium. Please note, this is not an exhaustive list. Please discuss with your pharmacist or doctor if you have any concerns.
  • Severe skin reaction where the top layer of the skin detaches from the lower layers.

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

If your nausea (feeling of sickness) or vomiting does not go away, ask your doctor what to do.

In certain illnesses and treatments where ondansetron has been used, blood vessel blockage has occurred.

However, it is important to note that blood vessel blockage has also occurred in these illnesses and treatments when ondansetron has NOT been used. Discuss this with your doctor if you have any concerns.

Tell your doctor or pharmacist if you notice anything that is making you feel unwell.

Other side effects not listed above may also occur in some people.

Some of these side effects (for example blood pressure) can only be found when your doctor does tests from time to time to check your progress.

After taking Ondansetron ODT Lupin


Keep your medicine in its original packaging until it is time to take it. If you take your medicine out of its original packaging it may not keep well.

Keep your medicine in a cool dry place where the temperature stays below 25°C.

Do not store any 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 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 this medicine or the expiry date has passed, your pharmacist can dispose of the remaining medicine safely.
