This drug should not be used with the following medications because very serious (possibly fatal) interactions may occur: cisapride, pimozide.

If you are currently using either of these medications listed above, tell your doctor or pharmacist before starting aprepitant.

Before using this medication, tell your doctor or pharmacist of all prescription and nonprescription/herbal products you may use, especially of: drugs affecting liver enzymes that remove aprepitant from your body (such as azole antifungals including itraconazole, macrolide antibiotics including erythromycin, cimetidine, rifamycins including rifabutin, St. John's wort, certain anti-seizure medicines including carbamazepine/phenytoin, certain cancer chemotherapy drugs including ifosfamide/vinblastine/vincristine).

Aprepitant can both speed up and slow down the removal of other drugs from your body, thereby affecting how they work. These affected drugs include (not a complete list): benzodiazepines (e.g., alprazolam, midazolam, triazolam), simvastatin, drugs to treat male sexual function problems (e.g., sildenafil).

If you take warfarin, this drug may affect how well warfarin works in your body. Therefore, your doctor should test your blood during the 2 weeks after your aprepitant treatment to measure how well warfarin is working.

This medication may decrease the effectiveness of hormonal birth control (e.g., pill, patch, ring). This effect can result in pregnancy. Ask your doctor or pharmacist for details. Discuss whether you should use additional reliable birth control methods during treatment with aprepitant and for 1 month after the last dose of aprepitant.
