What is aprepitant?

Aprepitant is used together with other medications to prevent nausea and vomiting that may be caused by chemotherapy.

Aprepitant is given ahead of time and will not treat nausea or vomiting that you already have.

Aprepitant capsules are for use in adults and children who are at least 12 years old. Aprepitant oral suspension (liquid) can be given to adults and children as young as 6 months old.

Aprepitant may also be used for purposes not listed in this medication guide.

You should not use aprepitant if you are allergic to it, or if you use another medicine called pimozide. Aprepitant can cause unwanted or dangerous side effects when used with pimozide.

Tell your doctor if you have ever had:

  • liver disease.

Tell your doctor if you are pregnant or breastfeeding. You should not be treated with aprepitant injection if you are pregnant.

Aprepitant can make hormonal birth control less effective, including birth control pills, injections, implants, skin patches, and vaginal rings. To prevent pregnancy while using aprepitant, use a barrier form of birth control: condom, diaphragm, cervical cap, or contraceptive sponge.

Keep using the barrier form of birth control for 1 month after your last dose of aprepitant.

Aprepitant is not for long-term use. You will most likely need only 1 to 3 doses.

The first dose of aprepitant is usually given 30 to 60 minutes before treatment with chemotherapy. Follow your doctor's dosing instructions very carefully.

Aprepitant oral can be taken with or without food.

Swallow the capsule whole and do not crush, chew, break, or open it.

Give the oral suspension (liquid) using only the dosing syringe provided.

If you also take warfarin (Coumadin, Jantoven), you may need extra "INR" or prothrombin time tests after you have used aprepitant.

Store aprepitant capsules at room temperature away from moisture and heat.

Store the prefilled liquid dosing syringe in the refrigerator, do not freeze. After taking the liquid out of the refrigerator, you must use it within 3 hours.

Throw away any liquid medicine not used within 3 days (72 hours) after you received it. Do not save it for later use.
