1. What is Kytril and what is it used for
Kytril contains the active substance granisetron. This belongs to a group of medicines called serotonin receptor antagonists, 5-HT3, or antiemetics, which means they prevent or stop nausea and vomiting.
Kytril is used to prevent and treat nausea and vomiting caused by certain treatments, such as chemotherapy or radiotherapy in anticancer therapy, as well as to treat and prevent post-operative nausea and vomiting.
The injectable solution is indicated in adults and children aged 2 years and older.
2. What you need to know before you use Kytril
Do not use Kytril
? if you are allergic (hypersensitive) to granisetron or any of the other ingredients of Kytril (listed in section 6: Further information).
If you are not sure, consult your doctor, nurse or pharmacist before receiving the injection.
Warnings and precautions
Consult your doctor, nurse or pharmacist before starting to use Kytril, especially if you:
? have problems with constipation due to intestinal obstruction
? have heart problems, are receiving anticancer medicines that can be harmful to your heart, and/or have some disorder of salt levels such as potassium, sodium or calcium (electrolyte disturbances).
? are taking another medicine from the group of “5-HT3 receptor antagonists”. This group includes dolasetron and ondansetron, used, like Kytril, for the treatment and prevention of nausea and vomiting.
Serotonin Syndrome is a rare 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,butit is more likely to occur if you take granisetron with other medicines (in particular fluoxetine, paroxetine, sertraline, fluvoxamine, citalopram, escitalopram, venlafaxine, duloxetine). The risk of serotonin syndrome also increases if you are taking medicines that contain buprenorphine or other opioids. Make sure to tell your doctor, nurse or pharmacist all the medicines you are taking.
Other medicines and Kytril
Tell your doctor, nurse or pharmacist if you are using or have recently used or might use other medicines, even those bought without a prescription. This is because Kytril may interact with some medicines. Also, some medicines may interact with this injection.
Tell your doctor, nurse or pharmacist if you are taking or might take other medicines:
? medicines used to treat irregular heartbeats, other “5-HT3 receptor antagonists” such as dolasetron or ondansetron (see “Warnings and precautions”).
? phenobarbital, a medicine used to treat epilepsy
? ketoconazole, a medicine used to treat fungal infections
? erythromycin, an antibiotic used to treat bacterial infections
? SSRIs (selective serotonin reuptake inhibitors) used to treat depression and/or anxiety. For example: fluoxetine, paroxetine, sertraline, fluvoxamine, citalopram, escitalopram
? SNRIs (serotonin and norepinephrine reuptake inhibitors) used to treat depression and/or anxiety. For example: venlafaxine, duloxetine
- Medicines that contain buprenorphine or other opioids.

3. How to use Kytril
The injection will be given to you by your doctor or nurse. The recommended dose of Kytril varies from one patient to another. This depends on age, weight, and whether you are taking other medicines to prevent or treat nausea and vomiting. Your doctor will decide how much to give you.
Kytril can be given as an injection into the veins (intravenously).
Prevention of nausea or vomiting after radiotherapy or chemotherapy
You will be given the injection before you start radiotherapy or chemotherapy. The injection into the veins (intravenously) will last between 30 seconds to 5 minutes and the usual dose is between 1 and 3 mg. The medicine may be diluted before injection.
Treatment of nausea or vomiting after radiotherapy or chemotherapy
The injection will last between 30 seconds to 5 minutes and the usual dose is between 1 and 3 mg. The medicine may be diluted before injection into the veins (intravenously). To stop the discomfort, you may receive more injections after the first dose. There must be at least 10 minutes between each dose. The maximum dose of Kytril will be 9 mg per day.
Combination with corticosteroids
The effect of the injection may be increased with the use of other medicines, called corticosteroids. This may be 8-20 mg of dexamethasone, given before the start of radiotherapy or chemotherapy treatment, or 250 mg of methylprednisolone given before the start of chemotherapy and again immediately after finishing it.
Use in children for the prevention or treatment of nausea or vomiting after radiotherapy or chemotherapy
Kytril is given by injection into the veins (intravenously) as described above, with the dose adjusted according to the child's weight. The injections are diluted and given before radiotherapy or chemotherapy and last 5 minutes. Children may receive a maximum of 2 doses per day, with at least 10 minutes between each dose.

Use in children for the prevention or treatment of nausea or vomiting after an operation
