Dolasetron injection is used to prevent and treat nausea and vomiting that may occur after surgery. Dolasetron injection should not be used to prevent or treat nausea and vomiting in people receiving cancer chemotherapy medications. Dolasetron is in a class of medications called serotonin 5-HT3 receptor antagonists. It works by blocking the action of serotonin, a natural substance that may cause nausea and vomiting.
Dolasetron injection comes as a solution (liquid) to be injected intravenously (into a vein) by a healthcare provider in a hospital or clinic. It is usually given as a single injection just before the end of surgery or as soon as nausea or vomiting occurs.
Dolasetron injection may be mixed in apple or apple-grape juice for children to take by mouth. It usually is given within 2 hours before surgery. This mixture may be kept at room temperature but must be used within 2 hours after mixing.
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
