What Navoban is used for

Navoban is used to prevent nausea (feeling sick) and vomiting caused by surgery and by cancer chemotherapy.
The active ingredient in Navoban is tropisetron. It works by stopping the action of a substance in the body called SEROTONIN that is thought to cause the nausea and vomiting.
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.
Navoban is only available with a doctor's prescription. It is not addictive.
There is not enough information to recommend its use in children.

Before you have Navoban

When you must not have it

Do not have Navoban if you have ever had an allergy to:
tropisetron (the active ingredient in Navoban)
any of the other ingredients listed at the end of this leaflet
similar medicines such as ondansetron and dolasetron
Some of the symptoms of an allergic reaction may include shortness of breath, wheezing or difficulty breathing; swelling of the face, lips, tongue or other parts of the body; rash, itching or hives on the skin.
Do not have Navoban if you are pregnant.
There is not enough information to recommend its use during pregnancy.
Do not breast-feed while you are having Navoban.
It is not known if the active ingredient in Navoban passes into breast milk and could affect your baby.
Do not have Navoban after the expiry date printed on the pack or if the packaging is torn or shows signs of tampering.
In that case, return it to your pharmacist.

Before you start to have it

Tell your doctor if you have any of the following health problems / medical conditions:
kidney problems
liver problems
heart problems
high blood pressure that is not controlled
Your doctor may want to take special precautions if you have any of the above conditions.
Tell your doctor if you are lactose intolerant.
Navoban capsules contain lactose.
Tell your doctor if you have allergies to any other medicines, foods, dyes or preservatives.
Your doctor will want to know if you are prone to allergies.

Taking other medicines

Tell your doctor if you are taking any other medicines, including any that you buy without a prescription from a pharmacy, supermarket or health food shop.
Some medicines and Navoban may interfere with each other. These include:
some medicines for your heart
any medicine that has caused problems with your heart rhythm since this effect could be worsened
serotonergic drugs such as antidepressants
You may need to take different amounts of your medicines or to take different medicines while you are having Navoban. Your doctor and pharmacist have more information.
Tell your doctor if you are taking other serotonergic drugs. Serotonin syndrome (including altered mental status, autonomic instability and neuromuscular abnormalities) has been described following the concomitant use of tropisetron (active ingredient in NAVOBAN) and other serotonergic drugs including selective serotonin re-uptake inhibitors (SNRIs).
If you have not told your doctor about any of these things, tell him/her before you start having this medicine.

How Navoban is used

Follow all directions given to you by your doctor and pharmacist carefully.
These directions may differ from the information contained in this leaflet.
If you do not understand the instructions on the label, ask your doctor or pharmacist for help.

For nausea and vomiting caused by surgery

A single 2 mg dose is usually given by injection or through an intravenous drip shortly before surgery. If nausea and vomiting happen after surgery, a 2 mg dose of Navoban can be given at that time.

For nausea and vomiting caused by chemotherapy

A single 5 mg dose of Navoban is usually given by injection or through an intravenous drip shortly before chemotherapy is started.
This is followed by a 5 mg dose of Navoban each morning for up to 5 more days, usually taken by mouth in the form of a capsule.
Sometimes a medicine called dexamethasone is given along with Navoban to improve the control of nausea and vomiting.

How to take the capsule

Take the capsule with a full glass of water immediately after getting up in the morning. Wait at least an hour before you have breakfast.

If you forget to take it

If it is almost time for your next dose, skip the dose you missed and take the next dose when you are meant to.
Otherwise, take it as soon as you remember, and then go back to taking it as you would normally.
Do not take a double dose to make up for the one that you missed.
This may increase the chance of you getting an unwanted side effect.
If you have trouble remembering when to take your medicine, ask your pharmacist for some hints.

If you have too much (Overdose)

Immediately telephone your doctor or Poisons Information Centre (telephone 13 11 26), or go to Accident and Emergency at your nearest hospital if you think that you or anyone else may have had too much Navoban. Do this even if there are no signs of discomfort or poisoning. Keep the telephone numbers for these places handy.
At very high doses, some people may have visual hallucinations (see things that are not there). People with high blood pressure may have their blood pressure raised even higher.

While you are having Navoban

Things you must not do
