Dosage and administration 2 DOSAGE AND ADMINISTRATION Recommended Adult Dosage ( 2.1 ) EMEND for injection 150 mg on Day 1 as an intravenous infusion over 20 to 30 minutes. ( 2.1 ) Complete the infusion approximately 30 minutes prior to chemotherapy. Recommended Dosage for Pediatric Patients (6 months to 17 years) Weighing at Least 6 kg ( 2.2 ) See Full Prescribing Information for pediatric dosage regimens by age. For single dose chemotherapy regimens : single dose of EMEND for injection on Day 1. For single- or multi-day chemotherapy regimens : 3-day EMEND regimen of EMEND for injection on Days 1, 2, and 3. EMEND capsules or EMEND for oral suspension may be used as an alternative on Days 2 and 3. Administer EMEND for injection through a central venous catheter as an intravenous infusion over 30 minutes (12 years to 17 years) or 60 minutes (6 months to less than 12 years). Complete the infusion approximately 30 minutes prior to chemotherapy. Concomitant Antiemetics See Full Prescribing Information for additional information. ( 2.1 , 2.2 ) 2.1 Prevention of Nausea and Vomiting Associated with HEC and MEC in Adult Patients The recommended dosage of EMEND for injection, dexamethasone, and a 5-HT 3 antagonist for the prevention of nausea and vomiting associated with administration of HEC or MEC in adults is shown in Table 1 or Table 2, respectively. Administer EMEND for injection as an intravenous infusion on Day 1 over 20 to 30 minutes, completing the infusion approximately 30 minutes prior to chemotherapy. Table 1 Recommended Adult Dosing for the Prevention of Nausea and Vomiting Associated with HEC Day 1 Day 2 Day 3 Day 4 EMEND for injection 150 mg intravenously over 20 to 30 minutes none none none Dexamethasone Administer dexamethasone 30 minutes prior to chemotherapy treatment on Day 1 and in the morning on Days 2 through 4. Also administer dexamethasone in the evenings on Days 3 and 4. A 50% dosage reduction of dexamethasone on Days 1 and 2 is recommended to account for a drug interaction with EMEND [see Clinical Pharmacology (12.3) ] . 12 mg orally 8 mg orally 8 mg orally twice daily 8 mg orally twice daily 5-HT 3 antagonist See selected 5-HT 3 antagonist prescribing information for the recommended dosage none none none Table 2 Recommended Adult Dosing for the Prevention of Nausea and Vomiting Associated with MEC Day 1 EMEND for injection 150 mg intravenously over 20 to 30 minutes Dexamethasone Administer dexamethasone 30 minutes prior to chemotherapy treatment on Day 1. A 50% dosage reduction of dexamethasone is recommended to account for a drug interaction with EMEND [see Clinical Pharmacology (12.3) ] . 12 mg orally 5-HT 3 antagonist See selected 5-HT 3 antagonist prescribing information for the recommended dosage 2.2 Prevention of Nausea and Vomiting Associated with HEC and MEC in Pediatric Patients The recommended pediatric dosage regimens of EMEND, to be administered with a 5-HT 3 antagonist, with or without a corticosteroid, for the prevention of nausea and vomiting associated with administration of single or multi-day chemotherapy regimens of HEC or MEC, are shown in Tables 3 and 4. Single-day chemotherapy regimens include regimens in which HEC or MEC is administered for a single day only. Multi-day chemotherapy regimens include chemotherapy regimens in which HEC or MEC is administered for 2 or more days. EMEND Dosage Regimens for Use with Single-Day Chemotherapy Regimens For pediatric patients weighing at least 6 kg receiving single-day HEC or MEC, EMEND may be administered as: a single dose regimen of EMEND for injection infused through a central venous catheter on Day 1, as shown in Table 3; or as a 3-day EMEND regimen consisting of EMEND for injection as an intravenous infusion through a central venous catheter on Da
Monitoring
- • 5 WARNINGS AND PRECAUTIONS CYP3A4 Interactions: Fosaprepitant is a weak inhibitor of CYP3A4, and aprepitant, the active moiety, is a substrate, inhibitor, and inducer of CYP3A4; see Full Prescribing Information for recommendations regarding contraindications, risk of adverse reactions, and dosage adjustment of EMEND and concomitant drugs.
- • ( 4 , 5.1 , 7.1 , 7.2 ) Hypersensitivity Reactions (including anaphylaxis and anaphylactic shock): May occur during or soon after infusion.
- • If symptoms occur, discontinue the drug.
- • Do not reinitiate EMEND if symptoms occur with previous use.
Interaction Notes
- • 7 DRUG INTERACTIONS See Full Prescribing Information for a list of clinically significant drug interactions.
- • ( 4 , 5.1 , 5.4 , 5.5 , 7.1 , 7.2 ) 7.1 Effect of Fosaprepitant/Aprepitant on the Pharmacokinetics of Other Drugs When administered intravenously, fosaprepitant, a prodrug of aprepitant, is converted to aprepitant within 30 minutes.
- • Therefore, drug interactions following administration of EMEND for injection are likely to occur with drugs that interact with oral aprepitant.
- • Fosaprepitant, given as a single 150-mg dose, is a weak inhibitor of CYP3A4, and the weak inhibition of CYP3A4 continues for 2 days after single dose administration.
