Important information about EMEND
EMEND is only used to help prevent nausea and vomiting caused by chemotherapy. It is not used to get rid of nausea and vomiting after they start.
Do not take EMEND if you are taking Orap (pimozide), Seldane (terfenadine), Hismanal (astemizole), or Propulsid (cisapride). Taking EMEND with these medicines could cause serious or life-threatening problems. EMEND may also affect some medicines, including chemotherapy, causing them to work differently in your body. Patients taking Coumadin (warfarin) may need to have blood tests after taking EMEND to check their blood clotting. Women who use birth control medicines during treatment with EMEND and for up to 1 month after using EMEND should also use a backup method of contraception to avoid pregnancy.
Tell your doctor if you are taking or plan to take prescription or nonprescription medicines, vitamins, or herbal supplements, or if you have liver problems. Tell your doctor if you are pregnant or plan to become pregnant because it is not known if EMEND can harm your unborn baby. Tell your doctor if you are breast-feeding because it is not known if EMEND passes into your milk or if it can harm your baby.
You are encouraged to report negative side effects of prescription drugs to the FDA. Visit www.fda.gov/medwatch, or call 1-800-FDA-1088.
