Ondansetron Injection USP 4mg

It belongs to a class of drugs called antiemetics used to prevent nausea and vomiting during chemotherapy. Nausea is a feeling of uneasiness of the stomach that often comes before vomiting. On the other hand, vomiting is the forcible voluntary or involuntary emptying of stomach contents through the mouth.

It contains Ondansetron which works by blocking the action of serotonin, a chemical that stimulates the vomiting centre (chemoreceptor trigger zone – CTZ) located in the brain. Thus, it prevents nausea and vomiting.
