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 (feeling sick) 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 for adults and children aged 2 years and older.
2. What you need to know before taking 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, talk to your doctor, nurse or pharmacist before receiving the injection.
Warnings and precautions
Talk to 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 about 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 take other medicines, including those bought without a prescription. This is because Kytril may interact with some medicines. Also, some medicines may interact with this injection.

? 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

Kytril can be given as an injection into the veins (intravenously).

Combination with corticosteroids
The effect of the injection may be increased by the use of other medicines, called corticosteroids. This may be 8-20 mg of dexamethasone, given before the start of radiotherapy or chemotherapy, 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.
