1. What Granisetron infusion/injection is and what it is used for

Granisetron infusion/injection contains a medicine called granisetron. This belongs to a group of medicines called ‘5-HT3 receptor antagonists’ or ‘anti-emetics’.

Granisetron infusion/injection is used to prevent or treat nausea and vomiting (feeling and being sick) caused by other medical treatments, such as chemotherapy or radiotherapy for cancer, and by surgery.

The solution for infusion or injection is for use in adults and children from 2 years old.

2. What you need to know before Granisetron infusion/injection is given to you

Do not use Granisetron infusion/injection:

  • if you are allergic to granisetron or any of the other ingredients of this medicine (listed in section 6).

If you are not sure, talk to your doctor, nurse or pharmacist before having the infusion or injection.

Warnings and precautions

Talk to your doctor, nurse or pharmacist before Granisetron infusion/injection is given to you:

−if you are having problems with your bowel movements because of a blockage of your gut (intestines)
−if you have heart problems, are being treated for cancer with a medicine that is known to damage your heart or have problems with levels of salts, such as potassium, sodium or calcium, in your body (electrolyte abnormalities)
−if you are taking other ‘5-HT3 receptor antagonist’ medicines. These include dolasetron, ondansetron used like granisetron in the treatment and prevention of nausea and vomiting.

Serotonin syndrome is an uncommon but potentially life-threatening reaction that can occur with granisetron (see section 4). It can cause serious changes in how your brain, muscles, and digestive system work. The reaction can occur if you take granisetron alone but it is more likely to occur if you take granisetron with certain other medicines (in particular fluoxetine, paroxetine, sertraline, fluvoxamine, citalopram, escitalopram, venlafaxine, duloxetine).

Other medicines and Granisetron infusion/injection

Tell your doctor, nurse or pharmacist if you are taking, have recently taken or might take any other medicines. This is because Granisetron infusion/injection can affect the way some medicines work. Also some other medicines can affect the way this infusion/injection works.

In particular, tell your doctor, nurse or pharmacist if you are taking the following medicines:

−medicines used to treat an irregular heartbeat other ‘5-HT3 receptor antagonist’ medicines such as dolasetron or ondansetron (see “Warnings and precautions” above)
−phenobarbital, a medicine used to treat epilepsy
−a medicine called ketoconazole used in the treatment of fungal infections
−the antibiotic erythromycin used to treat bacterial infections.
−

SSRIs (selective serotonin reuptake inhibitors) used to treat depression and/or anxiety.

Examples are fluoxetine, paroxetine, sertraline, fluvoxamine, citalopram, escitalopram.

−SNRIs (serotonin noradrenaline reuptake inhibitors) used to treat depression and/or anxiety. Examples are venlafaxine, duloxetine.

If you are pregnant or breastfeeding, think you may be pregnant or are planning to have a baby, ask your doctor, nurse or pharmacist for advice before Granisetron infusion/injection is given to you.

Information on sodium content

3. How Granisetron infusion/injection will be given to you

The infusion/injection will be given to you by a doctor or nurse. The dose of granisetron varies from one patient to another. It depends on your age, weight, and whether you are being given the medicine to prevent, or treat, nausea and vomiting. The doctor will work out how much to give you.

Granisetron can be given as an injection or infusion into the veins (intravenous).

Prevention of feeling or being sick following radio- or chemotherapy

You will be given the injection or infusion before your radio- or chemotherapy starts. The injection or infusion into your veins will take between 30 seconds (injection) and 5 minutes (infusion) and the dose will usually be between 1 and 3 mg. The medicine may be diluted before it is injected or infused.

Treatment of feeling or being sick following radio- or chemotherapy

The injection or infusion will take between 30 seconds (injection) and 5 minutes (infusion) and the dose will usually be between 1 and 3 mg. The medicine may be diluted before it is injected or infused into your veins. You may be given more injections or infusions to stop your sickness after the first dose. There will be at least 10 minutes between each dose. The most granisetron you will be given is 9 mg a day.

Combination with steroids

The effect of the injection may be improved by the use of medicines called adrenocortical steroids. The steroid will be given either as a dose between 8 and 20 mg dexamethasone before your radio- or chemotherapy or as 250 mg methyl-prednisolone, which will be given both before and after your radio- or chemotherapy.

Use in children in the prevention or treatment of feeling or being sick following radio- or chemotherapy

Children will be given granisetron by infusion into the vein as described above with the dose depending on the child’s weight. The infusions will be diluted and be given before radio- or chemotherapy and will take 5 minutes. Children will be given a maximum of 2 doses a day, at least 10 minutes apart.

Treatment of feeling or being sick following surgery

The injection or infusion into your veins will take between 30 seconds (injection) and 5 minutes (infusion) and the dose will usually be 1 mg. The most granisetron you will be given is 3 mg a day.

Use in children in the prevention or treatment of feeling or being sick following surgery

Children should not be given this injection to treat sickness or the feeling of sickness after surgery.

If you are given more Granisetron than you should

Because the injection will be given to you by a doctor or nurse, it is unlikely that you will be given too much. However, if you are worried talk to your doctor or nurse. Symptoms of overdose include mild headaches. You will be treated depending on your symptoms.
