Ondansetron is used to treat which symptom?

Explanation:
The key idea is that ondansetron is an antiemetic that blocks serotonin 5-HT3 receptors to prevent nausea and vomiting. By inhibiting receptors in the chemoreceptor trigger zone and in the gut, it reduces the body's tendency to vomit, especially in situations like chemotherapy or after surgery. Therefore, the symptom it treats is nausea (and it can help prevent vomiting). It isn’t used for cough, dizziness, or headaches, which have different underlying causes and treatments.
