Ondef 2mg Drop 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.
