Ondimark Syrup is primarily used in the prevention of vomiting and nausea. Nausea is an uneasy feeling in which a person feels an urge to vomit, while vomiting is the natural response of the body to expel the stomach contents from the mouth forcefully.

Ondimark Syrup contains Ondansetron, which works by blocking the action of a chemical in the body (serotonin) responsible for causing nausea and vomiting.

You may experience common side effects such as constipation, headache, diarrhea, drowsiness, flushing (a feeling of warmth), weakness, and tiredness. If the side effects persist or worsen, please consult your doctor.

Before using Ondimark Syrup, inform your doctor if you are allergic to any of its ingredients. Ondimark Syrup should be used during pregnancy and breastfeeding only if prescribed by a doctor.
