1. What Ondansetron B. Braun 2 mg/ml is and what it is used for

Ondansetron B. Braun 2 mg/ml belongs to a group of medicines called antiemetics, used to treat nausea or feeling unwell. Certain medical treatments for cancer (chemotherapy) or radiotherapy may make you feel sick (nausea) or cause you to vomit. You may also experience nausea or vomiting after surgery.
Ondansetron B. Braun 2 mg/ml can help reduce these effects in adults and children from the age of 6 months:

  • to treat nausea and vomiting after cancer therapy in children from the age of one month;
  • to prevent and treat nausea and vomiting after surgery.

2. What you should know before taking Ondansetron B. Braun 2 mg/ml

Ondansetron B. Braun 2 mg/ml must not be administered (please inform your doctor):

  • if you are allergic to ondansetron or to any of the other ingredients of this medicine (listed in section 6).

  • if you are taking apomorphine (a medicine used to treat Parkinson's disease). Warnings and precautions
    Talk to your doctor or pharmacist before taking this medicine. Special caution will be taken with this medicine:

  • If you are allergic to other medicines used to treat nausea or motion sickness, because you may develop an allergy to this medicine.

  • If you have intestinal obstruction or suffer from severe constipation. Ondansetron may worsen the obstruction or constipation.

  • If you have taken medicines that are harmful to the heart.

  • If you have disturbances in blood electrolyte levels, such as potassium, sodium, or magnesium.

  • If you have an irregular heartbeat (arrhythmia).

  • If your liver function is impaired. If your child is taking this medicine and is also receiving anticancer medicines that affect the liver, the doctor will monitor your child's liver function.

Other medicines and Ondansetron B. Braun 2 mg/ml
Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.
In particular, it is important that your doctor knows if you are taking:

  • certain medicines used to treat epilepsy (e.g. phenytoin, carbamazepine);
  • an antibiotic called rifampicin;
  • a strong painkiller called tramadol;
  • medicines used to treat depression (such as fluoxetine, sertraline, duloxetine, venlafaxine);
  • apomorphine (a medicine used to treat Parkinson's disease), because a marked drop in blood pressure and loss of consciousness have been reported following concomitant administration with this medicine;
  • medicines that affect the rhythm or function of the heart, including:
    • anticancer medicines such as anthracyclines (e.g. doxorubicin, daunorubicin, or trastuzumab),
    • antibiotics (e.g. erythromycin, ketoconazole), or
    • beta-blockers (e.g. atenolol, timolol);
  • antiarrhythmics (such as amiodarone). Pregnancy and breastfeeding Due to insufficient experience, the use of ondansetron during pregnancy is not recommended. Ondansetron is excreted in animal milk. Therefore, mothers receiving ondansetron must not breastfeed. If you are pregnant, think you may be pregnant, are planning a pregnancy, or are breastfeeding, consult your doctor or pharmacist before taking this medicine. Driving and using machines Ondansetron does not affect or affects negligibly the ability to drive or operate machinery. Ondansetron B.

3. How to take Ondansetron B. Braun 2 mg/ml

Method of administration
Ondansetron B. Braun 2 mg/ml is administered as an intravenous or intramuscular injection (into a vein or muscle), or, after dilution, as an intravenous infusion (over a longer period).
It is usually administered by a doctor or nurse.

Dosage
Your doctor will decide the correct dose of ondansetron therapy suitable for you.
The dose varies depending on the type of medical treatment (chemotherapy or surgery), liver function, and the method of administration (injection or infusion).

In the case of chemotherapy or radiotherapy, 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
Your doctor will determine the dose individually.

Dosage adjustment
Patients with hepatic impairment:
For patients with liver problems, the dose should be adjusted to a maximum daily dose of 8 mg of ondansetron.

Patients with renal impairment or reduced sparteine/debrisoquine metabolism:
No adjustment of daily dosage, frequency, or route of administration is required.

Elderly patients
Aged 65–74 years: the same dosing regimen as for adults may be followed.
Over 74 years of age: specific dosage requirements must be observed. Your doctor is aware of these requirements and will administer, where possible, a lower initial dose of this medicine compared to younger patients. Furthermore, you will receive this medicine only after dilution in another solution.

Duration of treatment
Your doctor will decide the appropriate duration of ondansetron therapy for you.
After intravenous administration of ondansetron 2 mg/ml, treatment may continue with another dosage form.

What to do in case of overdose of Ondansetron B. Braun 2 mg/ml
Since this medicine will be administered by a doctor or nurse, it is unlikely that you or your child will receive an excessive dose. If you think that you or your child has received too much or has missed a dose, inform your doctor or nurse.

Currently, information available regarding ondansetron overdose is limited. In most patients, symptoms were similar to those already reported in patients receiving the recommended doses of this medicine (see section “Possible side effects”). After overdose, the following effects have been observed: visual disturbances, severe constipation, low blood pressure, and unconsciousness. In all cases, these events resolved completely.

This medicine may alter heart rhythm, especially if you have received an overdose. In such cases, your doctor will monitor your heart rate more closely.

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

Inform your doctor immediately if any of these symptoms occur.

If you have any doubts about the use of this medicine, consult your doctor or pharmacist.

The following information is intended exclusively for healthcare professionals:

QT interval prolongation
Rare cases, mainly associated with intravenous administration of ondansetron, have reported transient ECG changes, including QT interval prolongation. Additionally, cases of torsade de pointes have been reported in patients receiving ondansetron. Caution is advised in patients who have or may develop QTc interval prolongation. Such conditions include patients with electrolyte abnormalities, congenital long QT syndrome, or those taking other medicinal products known to prolong the QT interval. Therefore, caution should be exercised in patients with cardiac rhythm or conduction disorders, in patients treated with antiarrhythmic agents or beta-adrenergic blocking agents, and in patients with significant electrolyte disturbances.

Serotonin syndrome
Post-marketing reports have described cases of serotonin syndrome (including altered mental status, autonomic instability, and neuromuscular abnormalities) following concomitant use of ondansetron and other serotonergic medicinal products (including selective serotonin reuptake inhibitors [SSRI] and serotonin-norepinephrine reuptake inhibitors [SNRI]). If concomitant treatment with ondansetron and other serotonergic medicinal products is clinically warranted, appropriate patient monitoring is recommended.
