2.Concurrent use with CYP3A4 inducers (e.g. carbamazepine, phenytoin, rifampicin, primidone, phenobarbital) may lead to reduced efficacy of Aprepitant
3.May decrease concentrations of CYP2C9 substrates e.g. phenytoin, tolbutamide, warfarin
4.May increase plasma levels of dexamethasone and methylprednisolone
5.May increase plasma levels of benzodiazepine (e.g. midazolam, diazepam, alprazolam)
6.Serum concentrations of colchicine may increase with Aprepitant
7.May increase toxicity of chemotherapy drug metabolised by CYP3A4 e.g. docetaxel, etoposide, ifosfamide, imatinib, paclitaxel, vincristine, vinblastin
8.May increase levels of ergot derivatives resulting in ergotism
9.May reduce efficacy of oral contraceptives, use additional methods of contraception during treatment and for at least 1 mth following the last dose of Aprepitant.
10.Potentially Fatal: May result in increased serum levels of astemizole, cisapride, pimozide and terfenadine which can lead to life-threatening torsade de pointes arrhythmias.
Prophylaxis of chemotherapy-induced nausea and vomiting
Adult: To be given for 3 days as part of a regimen containing a corticosteroid and a 5HT3 antagonist. Day 1: 125 mg (1 hr before chemotherapy); days 2 and 3: 80 mg once daily.
Prophylaxis of postoperative nausea and vomiting

However, we do publish a comprehensive directory of Pharmacies, Chemists and Druggists in cities all over India. You can use this directory to find the medicine stores in your city (or area) that provide home delivery services for aprepitant and other medicines and health products. Home delivery services for aprepitant may be free or they may cost you depending on the pharmacy and the minimum order requirements. It would be best to get this clarified while placing the order.
Please be aware that you should take aprepitant only if a doctor has recommended or prescribed it. Some or all pharmacies who provide a home delivery service for medicines might insist on a prescription for aprepitant before they complete the sale. You can get this information while placing the order for aprepitant with the pharmacy.
Aprepitant is a generic medicine name and there are several brands available for it. Some of the brands for aprepitant might be better known than aprepitant itself. If the pharmacy that's willing to deliver medicines to your home doesn't have aprepitant in stock, you can ask for one of the branded alternatives for aprepitant.
