Q: Why do doctors prescribe Zofran ODT for chemotherapy-related nausea?
A: Chemotherapy can trigger nausea by causing the release of serotonin from cells in the gut. The drug works by blocking the specific receptors for this serotonin signal in both the digestive tract and the brain’s trigger zone, thereby modulating the signal that causes vomiting.

Q: Does Zofran ODT cause any long-term side effects if used frequently?
A: The drug is indicated for acute, short-term use only, typically for one to two days after a procedure or treatment. As it is not indicated for chronic use, a long-term safety profile is not officially defined for frequent or long-term administration.
Q: Does taking Zofran ODT affect blood pressure?
