Ondansetrón injectable solution should not be administered in the same syringe or infusion as other medications. Ondansetrón should only be mixed with those solutions for infusion recommended.

Pregnancy and breastfeeding

Ondansetrón should not be used during the first trimester of pregnancy. This is because it may slightly increase the risk of a baby being born with cleft lip and/or palate (openings or fissures in the upper lip or palate). If you are pregnant or breastfeeding, consult your doctor or pharmacist before using ondansetrón as this medication may cause damage to the fetus.

If you are a fertile woman, it is recommended that you use an effective contraceptive method.

If you are a fertile woman, your doctor or nurse should check if you are pregnant and perform a pregnancy test before starting treatment with ondansetrón.

Fertile women should use an effective contraceptive method during treatment with ondansetrón. Consult your doctor about the options for contraceptive methods.

If you become pregnant during treatment with ondansetrón, inform your doctor.

It is not recommended to breastfeed during treatment with ondansetrón. This medication may pass into breast milk and may affect your baby.

It is unlikely thatondansetrónwill affect your ability to drive and operate machinery.

Ondansetrón Normon contains sodium

Thismedication contains 7.2 mg of sodium (main component of table salt/for cooking) in each vial. This is equivalent to 0.36% of the maximum daily sodium intake recommended for an adult.

Ondansetron should always be administered by a qualified professional and never by oneself.

Ondansetron is administered as an intravenous injection (into a vein), intramuscular injection, or, after dilution, as an intravenous infusion (over a longer period of time).

Dose

Your doctor will decide on the correct dose of ondansetron treatment. The dose varies depending on your medical treatment (chemotherapy or surgery), liver function, and whether administration is by injection or infusion.

Nausea and vomiting induced by chemotherapy and radiation therapy

Adults:

On the day you undergo chemotherapy or radiation therapy, they will administer the usual adult dose of 8 mg via intravenous or intramuscular injection immediately before your treatment, and another 8 mg 12 hours later.

On subsequent days:

- The usual adult intravenous or intramuscular dose will not exceed 8 mg.

- Oral administration can begin 12 hours after chemotherapy or radiation therapy and can continue for up to 5 days. The usual dose is 8 mg twice a day.

If it is likely that your chemotherapy or radiation therapy will cause intense nausea and vomiting, they may administer a higher dose of ondansetron than usual. Your doctor will decide what to do. A single dose of more than 16 mg should not be administered due to the increased risk of dose-dependent prolongation of the QT interval.

Nausea and vomiting induced by chemotherapy

Children over 6 months and adolescents

Your doctor will decide the dose based on your child's weight or body surface area. On the day of chemotherapy: the first dose is administered via intravenous injection immediately before your child's treatment.

Normally, 12 hours after chemotherapy, your child will receive ondansetron orally. The usual dose is 4 mg twice a day and can continue for up to 5 days.

Postoperative nausea and vomiting

To prevent nausea and vomiting after surgery

Adults

The usual dose is 4 mg, administered via intravenous or intramuscular injection. This dose will be administered to you immediately before the procedure.

To treat nausea and vomiting after surgery

Adults

The usual adult dose is 4 mg, administered via intravenous or intramuscular injection.

Children over 1 month of age and adolescents.

Dose adjustments

Patients with liver insufficiency

In patients with liver problems, the dose should be adjusted to a maximum of 8 mg of ondansetron per day.

Older patients, patients with renal insufficiency, or slow metabolizers of sparteine/debrisoquine

No adjustment of the daily dose or frequency of the dose or route of administration is necessary.

Treatment duration

Your doctor will decide on the duration of your ondansetron treatment. Do not discontinue treatment prematurely. If you estimate that the action of ondansetron is too strong or too weak, inform your doctor or pharmacist.

If you are given more Ondansetron Normon than you should

This medication will be administered to you in the hospital. Your doctor or nurse will administer ondansetron to you or your child, so it is unlikely that you or your child will receive too much. If you believe that you or your child have received too much or not received a dose, inform your doctor or nurse. Symptoms of overdose may include vision problems, low blood pressure (which can cause dizziness or fainting) and palpitations (irregular heartbeat). In case of overdose or accidental ingestion, consult your doctor or pharmacist immediately or call the Toxicology Information Service (Telephone: 91 5620420) indicating the medication and the amount administered.

If not used immediately, the storage time and conditions before use are the responsibility of the user and should not normally exceed 24 hours at 2 – 8 °C, unless the dilution has occurred in controlled and validated aseptic conditions.

Compatibility with other drugs

The following drugs can be administered through the Y-connector of the intravenous administration equipment of ondansetron, in order to provide fluids with concentrations of 16-160μg/mL (8mg/500 mL, 8mg/50mL):

Cisplatino:at concentrations of up to 0.48mg/mL (240mg in 500 mL). Administration time of 1 to 8 hours.

Carboplatino: at concentrations of 0.18mg/mL - 9.9mg/mL (90mg in 500mL to 990mg in 100mL). Administration time 10-60 minutes.

Etopósido: at concentrations of 0.144mg/mL - 0.25mg/mL (72mg in 500mL to 250mg in 1L). Administration time 30-60 minutes.

Ceftazidima: administer by intravenous route doses of 250 mg-2000mg reconstituted with water for injection following the instructions of the leaflet (2.5mL for 250mg and 10mL for 2g of ceftazidima). Administration time about 5 minutes.

Ciclofosfamida: administer by intravenous route doses of 100mg-1g reconstituted with water for injection (5mL for each 100mg of ciclofosfamida) following the instructions of the leaflet. Administration time about 5 minutes.

Dexametasona:can be administered 20mg of sodium phosphate of dexametasona in the form of intravenous injection slow of 2-5 minutes of duration, through the Y-connector of an infusion equipment that provides 8 or 16 mg of ondansetron diluted in 50-100mL of a compatible infusion fluid in about 15 minutes. Compatibility between sodium phosphate of dexametasona and ondansetron has been demonstrated, which supports the administration of these drugs using the same administration equipment, producing concentrations in the administered fluid of 32μg - 2.5mg/mL of sodium phosphate of dexametasona and of 8μg - 1mg/mL of ondansetron.
