Ask your doctor what you should do if you already have nausea or vomiting.
How to use
This medication is given by injection into a vein by a health care professional. It is given as directed by your doctor, usually 30 minutes before the start of chemotherapy. Your doctor may also direct you to take a form of this medication given by mouth (aprepitant) for the next 2 days. Follow your doctor's instructions carefully. Children's dosage is based on weight and age. If you have any questions, ask your doctor or pharmacist.
