1. What Ondansetrón Kalceks is and what it is used for

Ondansetrón Kalceks contains a medicine called ondansetron. This belongs to a group of medicines called antiemetics which stop you feeling sick (nausea) or being sick (vomiting).

Adults

Ondansetron is used to prevent nausea and vomiting caused by chemotherapy and radiotherapy and to prevent and treat nausea and vomiting after an operation.

Children and Adolescents

Ondansetron is used to prevent nausea and vomiting caused by chemotherapy in children aged over 6 months and in adolescents.

Ondansetron is used to prevent and treat nausea and vomiting after an operation in children aged over 1 month and in adolescents.

2. What you need to know before you are given Ondansetrón Kalceks

Ondansetrón Kalceks must not be given to you if:

• you are allergic to ondansetron or any of the other ingredients of this medicine (listed in section 6);
• you are using apomorphine (for the treatment of Parkinson's disease).

This medicine must not be given to you if any of the above applies to you. If you are not sure, talk to your doctor or nurse before you are given this medicine.

Warnings and Precautions

Talk to your doctor or nurse before you are given this medicine if:

• you have symptoms of an allergic reaction, such as itching, difficulty breathing or swelling of the face, lips, throat or tongue;

• you are going to have a tonsillectomy. In this case, you will need to be closely monitored.

Other Medicines and Ondansetrón Kalceks

Tell your doctor or nurse if you are taking, have recently taken or might take any other medicines.

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

• apomorphine (see Ondansetrón Kalceks must not be given to you if);
• carbamazepine or phenytoin (used to treat epilepsy);
• rifampicin (used to treat infections such as tuberculosis);

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor for advice before taking this medicine.

Pregnancy

You should not use this medicine during the first trimester of pregnancy.

3. How to use Ondansetrón Kalceks

Ondansetron will be given to you by a doctor or nurse as an injection or infusion into a vein or as an injection into a muscle.

Ondansetron is also available in forms that can be taken by mouth, which allows the dose to be adjusted individually. However, this medicine is designed to be given only into a vein or muscle.

The dose you are given will depend on the treatment you are having.

Adults

To prevent nausea and vomiting caused by chemotherapy or radiotherapy

• On the day of chemotherapy or radiotherapy

Ondansetron should be given immediately before chemotherapy or radiotherapy. The usual dose for adults is 8 mg given as a slow injection into a vein or muscle, or by slow infusion into a vein.

• On subsequent days

After the initial treatment, your doctor may prescribe ondansetron for you to take by mouth. Follow the instructions in the package leaflet, as necessary. Always take ondansetron exactly as your doctor has told you.

If necessary, the dose may be increased up to 32 mg per day.

To prevent and treat nausea and vomiting after an operation

The usual dose for adults is 4 mg given as a slow injection into a vein or muscle.

Oral dosing can start 12 hours later. This treatment can continue for up to 5 days after chemotherapy. The oral dose is calculated based on body weight or body surface area. The total daily dose should not exceed the adult dose of 32 mg.

Overdose

Symptoms and signs

Experience with ondansetron overdose is limited, but in the event of accidental overdose, the following symptoms of intoxication may be expected: visual disturbances, severe constipation, hypotension, and a vasovagal episode with transient second-degree AV block. In all cases, the reactions experienced resolved completely. Ondansetron prolongs the QT interval with a dose-dependent trend.

Pediatric population

Cases have been reported in children with serotonin syndrome after accidental oral overdose of ondansetron (estimated excessive ingestion of 4 mg/kg) in infants and children from 12 months to 2 years.

Treatment

There is no specific antidote for ondansetron, so in cases of suspected overdose, symptomatic and supportive treatment should be provided as appropriate. ECG monitoring is recommended. Additional treatment should follow clinical guidelines or the recommendations of the National Institute of Toxicology, if available.

Ipecacuanha administration is not recommended to treat overdose, as it is unlikely that patients will respond due to the antiemetic action of ondansetron itself.
