Zofran is an anti-nausea and vomiting medication used primarily for patients receiving chemotherapy or radiation therapy, as well as after surgery. It contains ondansetron, which works by blocking serotonin receptors in the brain and gastrointestinal tract, which are responsible for stimulating the vomiting center. Zofran is used in the form of tablets or injections, depending on the severity of symptoms. It begins to work within a short period of time after taking it, making it an effective and rapid option for preventing nausea.
Zofran is characterized by its few side effects compared to other similar medications, but it may sometimes cause headaches, constipation, or dizziness. Therefore, it must be used under medical supervision, especially for patients suffering from heart or liver problems.
