1. What Kytril is and what it is used for
Kytril contains the active substance granisetron. It belongs to a group of medicines called serotonin 5-HT3 receptor antagonists, or antiemetics, which prevent or reduce nausea and vomiting.
Kytril is indicated for the prevention and treatment of nausea and vomiting (feeling of discomfort) caused by certain treatments, such as chemotherapy or radiotherapy in anticancer therapy, as well as for the treatment and prevention of postoperative nausea and vomiting.
The injectable solution is indicated in 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 to any of the other components of Kytril (listed in section 6: Further information).
If you are unsure, consult 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 constipation due to intestinal obstruction
? have heart problems, are receiving anticancer medicines that may be harmful to your heart, and/or suffer from disturbances in electrolyte levels such as potassium, sodium, or calcium (electrolyte imbalances).
? are taking another medicine from the group of “5-HT3 receptor antagonists.” This group includes dolasetron and ondansetron, which, like Kytril, are used for the treatment and prevention of nausea and vomiting.
Serotonin syndrome is an uncommon but potentially life-threatening reaction that may occur with granisetron (see section 4). It may cause serious changes in how your brain, muscles, and digestive system function. The reaction may occur if you take granisetron alone, but it is more likely to occur if you take granisetron with other medicines (particularly fluoxetine, paroxetine, sertraline, fluvoxamine, citalopram, escitalopram, venlafaxine, duloxetine). The risk of serotonin syndrome also increases if you are taking medicines containing buprenorphine or other opioids. Be sure to tell your doctor, nurse, or pharmacist about all medicines you are taking.
Other medicines and Kytril
Inform your doctor, nurse, or pharmacist if you are using or have recently used, or might take, any other medicines, including those obtained without a prescription. This is because Kytril may interact with certain medicines. Also, some medicines may interact with this injection.
Tell your doctor, nurse, or pharmacist if you are taking or may have taken any of the following 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 noradrenaline reuptake inhibitors) used to treat depression and/or anxiety. For example: venlafaxine, duloxetine
- Medicines containing buprenorphine or other opioids.
Pregnancy and breastfeeding
Do not receive this injection if you are pregnant, trying to become pregnant, or breastfeeding, unless your doctor has instructed you to do so.
If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor, nurse, or pharmacist before using this medicine.

3. How to use Kytril
The injection will be administered to you by your doctor or nurse. The recommended dose of Kytril varies from patient to patient. It depends on age, body weight, and whether you are taking other medications to prevent or treat nausea and vomiting. Your doctor will decide how much you should be given.
Kytril may be given as an injection into the veins (intravenous route).
Prevention of nausea or vomiting following radiotherapy or chemotherapy
The injection will be given before radiotherapy or chemotherapy begins. The intravenous injection will last between 30 seconds and 5 minutes, and the usual dose ranges between 1 and 3 mg. The medicine may be diluted before injection.
Treatment of nausea or vomiting following radiotherapy or chemotherapy
The injection lasts between 30 seconds and 5 minutes, and the usual dose is between 1 and 3 mg. The medicine may be diluted before intravenous injection. To control discomfort, additional injections may be given after the first dose, with at least 10 minutes between doses. The maximum daily dose of Kytril is 9 mg.
Combination with corticosteroids
The effect of the injection may be enhanced by using other medicines called corticosteroids. This may be 8–20 mg of dexamethasone, administered before the start of radiotherapy or chemotherapy, or 250 mg of methylprednisolone administered before the start of chemotherapy and again immediately after completion.
Use in children for prevention or treatment of nausea or vomiting following radiotherapy or chemotherapy
Kytril is administered by intravenous injection as described above, with the dose adjusted according to the child's body weight. The injections are diluted and administered before radiotherapy or chemotherapy, lasting 5 minutes. Children may receive up to 2 doses per day, with at least 10 minutes between doses.
Treatment of nausea or vomiting following surgery
The intravenous injection lasts between 30 seconds and 5 minutes, and the usual dose is 1 mg. The maximum daily dose of Kytril is 3 mg.
Use in children for prevention or treatment of nausea or vomiting following surgery
This injection must not be administered for the treatment of nausea or discomfort following surgery.
If you use more Kytril than you should
Because this injection is administered by a doctor or nurse, it is unlikely that you will receive more than the prescribed dose. However, if you are concerned, consult your doctor or nurse. Symptoms of overdose may include mild headache (cephalalgia). You will be treated according to your symptoms.
If you have any further questions about the use of this medicine, ask your doctor, nurse, or pharmacist.
