1. What Ondansetron Aristo is and what it is used for

This medicine contains ondansetron, which belongs to a group of medicines called antiemetics that help relieve nausea and vomiting.

Ondansetron is used to treat nausea (feeling of sickness) and vomiting caused by certain cancer treatments, such as chemotherapy (in adults and children) or radiotherapy (in adults).

It is also used to prevent nausea and vomiting in patients after surgery (adults).

2. Before taking Ondansetron Aristo

Do not take Ondansetron Aristo:

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

If you have or have had an allergic (hypersensitivity) reaction to other antiemetics (for example,

granisetron or dolasetron).

Warnings and precautions:

Take special care with Ondansetron Aristo:

• If you have intestinal obstruction or suffer from severe constipation.
• If you are undergoing tonsillectomy.
• If you have a heart condition.
• If you have a liver condition.

IF YOU ARE UNDERGOING ANY DIAGNOSTIC TESTS (INCLUDING BLOOD AND URINE TESTS, SKIN TESTS USING ALLERGENS, ETC.), INFORM YOUR DOCTOR THAT YOU ARE TAKING THIS MEDICINE, AS IT MAY ALTER TEST RESULTS.

Consult your doctor if any of the above circumstances apply to you before starting treatment with Ondansetron Aristo.

Use of Ondansetron Aristo with other medicines:

Ondansetron Aristo may have an effect on other medicines, and other medicines may have an effect on ondansetron.

Inform your doctor or pharmacist if you are using, or have recently used, any other medicines, even those obtained without a prescription.

In particular, it is important to inform your doctor if you are taking any of the following medicines, as dose adjustment may be necessary:

• Rifampicin (an antibiotic used to treat infections such as tuberculosis).
• Tramadol (a medicine used to treat pain).
• Phenytoin or carbamazepine (medicines used to treat epilepsy).
• Medicines used to treat heart problems, such as irregular heartbeats (antiarrhythmics) and/or high blood pressure (beta-blockers).
• Haloperidol or methadone (medicines that may affect the heart).
• Anthracyclines and trastuzumab (medicines used to treat cancer).
• Buprenorphine may interact with ondansetron and you may experience symptoms such as involuntary rhythmic muscle contractions, including muscles controlling eye movements, agitation, hallucinations, coma, excessive sweating, tremors, exaggerated reflexes, increased muscle tension, and body temperature above 38°C. Contact your doctor if you experience these symptoms.

Pregnancy and breastfeeding

Pregnancy:

Ondansetron Aristo should not be used during the first trimester of pregnancy. This is because Ondansetron Aristo may slightly increase the risk of a baby being born with cleft lip and/or cleft palate (openings or splits in the upper lip or in the roof of the mouth). If you are already pregnant, think you may be pregnant, or are planning to become pregnant, inform your doctor before taking Ondansetron Aristo. If you are a woman of childbearing age, you are advised to use an effective method of contraception.

Breastfeeding:

You must not breastfeed your baby while being treated with ondansetron.

Consult your doctor or pharmacist before using any medicine.

Driving and use of machines

It is unlikely that ondansetron will affect your ability to drive or operate machinery.

Important information about some of the components of Ondansetron Aristo:

This medicine contains sorbitol. If your doctor has informed you that you have an intolerance to certain sugars, consult him before taking this medicine.

This medicine may be harmful for people with phenylketonuria because it contains aspartame, a source of phenylalanine.

Treatment of nausea and vomiting in patients undergoing chemotherapy or radiotherapy:

Adults (including elderly)

Treatment of nausea and vomiting in patients undergoing chemotherapy:

Children (6 months of age and older) and adolescents (under 18 years):

The doctor will decide the appropriate dose of ondansetron. This will depend on the child's size and weight.

To prevent nausea and vomiting after surgery:

Adults: The usual dose is 16 mg before surgery or one 8 mg tablet one hour before surgery, followed by another 8 mg tablet eight hours after the first dose, and a third 8 mg tablet eight hours after the second dose.

The effect of ondansetron orodispersible tablets begins within one to two hours after taking the dose.

If you vomit within one hour after taking the 8 mg dose: take another 8 mg tablet, but do not take more ondansetron orodispersible tablets than indicated in this leaflet.

Patients with liver problems: The total daily dose should not exceed 8 mg.

If you take more Ondansetron Aristo than you should:

If you or your child take more ondansetron than you should, speak to a doctor or go immediately to the nearest hospital. Take the medicine with you.
