Frequently asked questions about ondansetron
What is ondansetron used to treat?
Ondansetron is used to prevent nausea and vomiting caused by cancer chemotherapy, radiation therapy, and surgery. It is typically given before the therapy or operation to prevent the feelings of nausea and vomiting from occurring. It is estimated that 70-80% of people undergoing chemotherapy or radiation therapy will experience nausea or vomiting. Nausea and vomiting are common side effects of anesthesia used in surgeries. When taken before surgery, ondansetron can help reduce the risk of this side effect.
How does ondansetron work?
Ondansetron is in the class of medications called serotonin 5-HT₃ receptor antagonists. It works on the body’s natural chemicals that are responsible for the nausea.
Chemotherapy and radiation therapy cause the release of serotonin 5-HT₃, a neurotransmitter in the central nervous system that triggers the nerves that bring about the vomiting reflex. Serotonin 5-HT₃ receptor antagonist medication- such as Ondansetron- blocks serotonin from reaching the nerves. This prevents feelings of nausea or the need to vomit.
