What should I tell my doctor before taking aprepitant?

Before taking aprepitant capsules (Emend), tell your doctor if you:

  • are allergic to any components of the medication (see the ingredients label)
  • take pimozide (Orap)
  • are pregnant or planning to become pregnant
  • are breastfeeding
  • are taking birth control pills, because aprepitant reduces the effectiveness of birth control pills
  • are taking blood thinners such as warfarin (Coumadin, Athrombin, Jantoven, Panwarfarin); your doctor will need to monitor your blood's ability to clot while taking aprepitant
  • have liver problems

If you have questions, talk with your doctor.
