Ondansetron

Ondansetron is an anti-emetic medicine used to help prevent nausea and vomiting. It is available in several forms and brand options, including tablets, orally disintegrating tablets, and syrup.

It works by blocking serotonin signals that can trigger nausea and vomiting. It is commonly used with chemotherapy, radiation therapy, and after surgery. Use it only as prescribed, and tell your clinician about all medicines you take, especially if you have heart rhythm problems or other medical conditions.
