  • an antibiotic called rifampicin,
  • a powerful pain reliever called tramadol,
  • medicines used to treat a depressed mood (such as fluoxetine, sertraline, duloxetine, venlafaxine),

    • anti-arrhythmics (such as amiodarone).

Pregnancy and breastfeeding

Ondansetron 2 mg/ml should not be used during the first trimester of pregnancy. This is because Ondansetron 2 mg/ml may slightly increase the risk of a baby being born with a cleft lip and/or cleft palate.

If you are already pregnant, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before using Ondansetron 2 mg/ml.

If you are a woman of childbearing age, you are advised to use an effective method of birth control.

Ondansetron passes into breast milk in animals. Therefore, mothers who are receiving ondansetron should NOT breastfeed.

Driving and using machines

Ondansetron has no or negligible influence on the ability to drive and use machines.

Ondansetron 2 mg/ml contains sodium

This medicine contains 3.34 mg of sodium (the main component of cooking/table salt) per milliliter. This is equivalent to 0.2% of the maximum recommended daily intake of sodium for an adult.

3. How to use Ondansetron 2 mg/ml

Method of administration

Ondansetron 2 mg/ml is administered as an intravenous or intramuscular injection (into a vein or into a muscle) or, after dilution, as an intravenous infusion (over a longer period). It will usually be administered by a doctor or by nursing staff.

Dose

Your doctor will decide the correct dose of ondansetron therapy for you.

The dose depends on your medical treatment (chemotherapy or surgery), your liver function, and whether it is administered by injection or infusion.

In the case of chemotherapy or radiation therapy, the usual dose in adults is 8-32 mg of ondansetron per day. For the treatment of postoperative nausea and vomiting, a single dose of 4 mg of ondansetron is usually administered.

Use in children over 1 month of age and adolescents

The doctor will decide the dose on an individual basis.

Dose adjustment

Patient with liver insufficiency

In patients with liver problems, the dose must be adjusted to a maximum daily dose of 8 mg of ondansetron.

Patient with renal insufficiency or patient with impaired metabolism of sparteine and debrisoquine

No alteration of the daily dose or the frequency of dosing or the route of administration is required.

Elderly patient

65-74 years: the individual dosage regimen for adults should be followed.

>74 years: special dosage requirements apply. Your doctor is aware of them and will take the precaution of administering a lower amount of this medicine as the first dose. Additionally, this medicine will only be administered to you if it is diluted in another solution.

Duration of treatment

Your doctor will decide the duration of ondansetron therapy for you.

After intravenous administration of Ondansetron 2 mg/ml, therapy may be continued with other routes of administration.

If you use more Ondansetron 2 mg/ml than you should

Your doctor or nurse will administer this medicine to you or your child, so it is unlikely that you or your child will receive more than the prescribed amount. If you think you or your child have been given too much, tell your doctor or nurse.

Currently, very little is known about the effects of an overdose with ondansetron. In most patients, the symptoms were similar to those reported in patients who received the recommended doses of this medicine (see section "Possible side effects"). In some patients, the following effects were observed after an overdose: visual disturbances, severe constipation, low blood pressure, and loss of consciousness. In all cases, the symptoms disappeared completely.

This medicine may alter your heart rhythm, especially in the case of an overdose. In this case, your doctor should monitor your heartbeat afterwards.

There is no specific antidote for ondansetron; therefore, if an overdose is suspected, only the symptoms should be treated.

Tell your doctor if you experience any of these symptoms.

If you have any further questions on the use of this medicine, ask your doctor or pharmacist.

--------------------------------------------------------------------------------------------------------------------

This information is intended only for healthcare professionals:

Prolongation of the QT interval

Rarely and predominantly with intravenous Ondansetron, transient changes in the ECG have been described, including prolongation of the QT interval. Additionally, cases of Torsade de pointes have been described in patients using ondansetron. Caution is advised in patients who have or may develop prolongation of the QTc interval. These disorders include patients with electrolyte imbalances, with congenital long QT syndrome, or patients who are taking other medicines that lead to prolongation of the QT interval. Therefore, caution is advised in patients with conduction or rhythm disorders, in patients treated with anti-arrhythmics or beta-adrenergic blockers, and in patients with significant electrolyte disturbances.

Serotonin syndrome

Pharmacovigilance reports have been received describing patients with serotonin syndrome (including altered mental status, autonomic instability, and neuromuscular abnormalities) after concomitant use of ondansetron and other serotonergic medicines (including selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs)). If concomitant treatment with ondansetron and other serotonergic medicines is clinically justified, appropriate observation of the patient is recommended.
