It is very important that your doctor check your progress at regular visits to make sure this medicine is working properly and to check for unwanted effects.

You should not receive fosaprepitant if you are also using pimozide (Orap®). Using these medicines together may cause serious unwanted effects.

This medicine may cause serious allergic reactions, including anaphylaxis, which can be life-threatening and requires immediate medical attention. Tell your doctor or nurse right away if you have itching, hives, a rash, trouble breathing, trouble swallowing, warmth or redness in your face, neck, arms, or upper chest, or any swelling of your hands, face, or mouth while you are receiving this medicine.

This medicine may cause infusion-related reactions, which can be life-threatening and require immediate medical attention. Tell your doctor right away if you start to have a fever, chills or shaking, dizziness, trouble breathing, itching or rash, lightheadedness or fainting after receiving this medicine.

If you are also using a blood thinner called warfarin (Coumadin®, Jantoven®), your doctor will need to check your blood after receiving this medicine.

Birth control pills may not work as well while you are receiving fosaprepitant. To keep from getting pregnant, use another form of birth control together with your pills during treatment and for 1 month after your last dose. Other forms include condoms, spermicides, a diaphragm, and contraceptive foam or jelly.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
