Zofran works by blocking the action of serotonin, a chemical in the brain that can trigger nausea and vomiting.

Factors that Affect Sleepiness

The amount of sleepiness that a person experiences after taking Zofran can depend on several factors, including their age, weight, overall health, and the dosage and frequency of their Zofran use.
