Dewstron Syrup belongs to a group of medications called ' anti-emetics' primarily used in the prevention of vomiting (being sick) and nausea (feeling sick) that usually occur after cancer chemotherapy, radiation treatment or surgery. Nausea is an uneasy feeling in which a person feels an urge to vomit while vomiting is the natural response to the body to forcefully discharge the stomach contents.

Dewstron Syrup contains 'Ondanestron' that works by blocking the action of a chemical in the body (serotonin) responsible for causing nausea and vomiting.
