Onset 8mg Iv/Im Injection 4ml

Working of this Medicine

Ondansetron in Onset Injection works by blocking serotonin (5-HT3) receptors in the gut and brain that trigger nausea and vomiting. It prevents the release of serotonin from the small intestine, stopping it from sending signals to the brain’s vomiting center. This dual action ensures rapid and long-lasting relief from nausea and vomiting, whether caused by treatment, infection, or surgery.
