Emeset is the brand name; the name of the medicine is ondansetron. It is indicated in the treatment of nausea and vomiting due to therapy with anti-cancer drug. However, due to aggressive promotion and ignorance on the part of some doctors, the drug is being inappropriately prescribed for normal nausea and vomiting even for very small children. Therefore the fact that someone, taking Emeset, must be a patient of malignancy is not necessarily the correct conclusion.
