From:
$11.98
Ondansetron is a prescription antiemetic used to prevent nausea and vomiting caused by chemotherapy, radiation therapy, surgery, and certain medical conditions. It works by blocking serotonin (5-HT3) receptors in the brain and the gastrointestinal tract, which trigger nausea and vomiting. This helps patients feel more comfortable and maintain hydration and nutrition during treatment.
