Emend – Aprepitant uses, dose and side effects

}

125 mg and 80 mg capsules, hard 
aprepitant

1. What EMEND is and what it is used for

EMEND contains the active substance aprepitant and belongs to a group of medicines called “neurokinin 1 (NK 1 ) receptor antagonists”. There is a special area in the brain that controls nausea and vomiting. EMEND works by blocking signals to that area, thus reducing nausea and vomiting. EMEND capsules are used in adults and adolescents from 12 years of age in combination with other medicines to prevent nausea and vomiting caused by chemotherapy (cancer treatment) which very or often causes nausea and vomiting (such as cisplatin, cyclophosphamide, doxorubicin, or epirubicin).

2. What you need to know before taking or giving EMEND

Do not take EMEND

  • if you or your child are allergic to aprepitant or any of the other ingredients of this medicine (listed in section 6).
  • together with medicines containing pimozide (used to treat psychiatric illnesses), terfenadine and astemizole (used to treat hay fever and other allergic conditions), cisapride (used to treat indigestion). Tell your doctor if you or your child are using these medicines as the treatment needs to be adjusted before you or your child starts using EMEND.

Warnings and cautions

Talk to your doctor, pharmacist, or nurse before taking EMEND or giving this medicine to your child.

If you or the child have any liver disease, talk to a doctor before treatment with EMEND. The liver has an important function in breaking down the drug in the body. Your doctor may therefore need to monitor your or your child’s liver function.

Children and young people

Do not give EMEND 80 mg and 125 mg capsules to children under 12 years of age, as the 80 mg and 125 mg capsules have not been studied in this age group.
