What Experts Say
Doctors and oncology teams commonly use ondansetron injections to prevent the severe nausea and vomiting that often accompany chemotherapy and radiotherapy sessions. This medicine works by blocking a chemical in the body called serotonin, which triggers the body's vomiting reflex, giving patients meaningful relief during difficult treatment cycles.
Hospitals also use this injection around the time of surgery, since anaesthesia and certain pain medicines can trigger nausea once the effects wear off. Giving the injection before symptoms start often works better than waiting until a patient already feels unwell and distressed.
This medicine is given by trained healthcare staff, usually as a slow injection into a vein or muscle. Patients with certain heart rhythm conditions need extra caution, since ondansetron can affect the heart's electrical activity in rare cases, especially at higher doses or with other similar medicines.
