Ertapenemdosage

Do not mix or co-infuse ertapenem for injection with other medications. Do not use diluents containing dextrose ( α –D–glucose). Ertapenem for injection should be infused over 30 minutes in both the Treatment and Prophylactic regimens. Dosing considerations should be made in adults with advanced or end-stage renal impairment and those on hemodialysis.

Treatment regimen: Adults and pediatric patients 13 years of age and older. The dosage should be 1 gram once a day intravenously or intramuscularly. Patients 3 months to 12 years of age should be administered 15 mg/kg twice daily (not to exceed 1 gram/day intravenously or intramuscularly). Intravenous infusion may be administered in adults and pediatrics for up to 14 days or intramuscular injection for up to 7 days.

Prophylaxis regimen for adults: 1 gram single dose given 1 hour prior to elective colorectal surgery.

2.1 Instructions for

Use in All Patients For Intravenous or Intramuscular Use DO NOT MIX OR CO-INFUSE ERTAPENEM FOR INJECTION WITH OTHER MEDICATIONS. DO NOT USE DILUENTS CONTAINING DEXTROSE (α-D-GLUCOSE). Ertapenem for injection may be administered by intravenous infusion for up to 14 days or intramuscular injection for up to 7 days. When administered intravenously, ertapenem for injection should be infused over a period of 30 minutes. Intramuscular administration of ertapenem for injection may be used as an alternative to intravenous administration in the treatment of those infections for which intramuscular therapy is appropriate.

2.2 Treatment

Regimen 13 years of age and older The dose of ertapenem for injection in patients 13 years of age and older is 1 gram (g) given once a day. 3 months to 12 years of age The dose of ertapenem for injection in patients 3 months to 12 years of age is 15 mg/kg twice daily (not to exceed 1 gram/day). Table 1 presents treatment guidelines for ertapenem for injection.

Regimen in Adults Table 2 presents prophylaxis guidelines for ertapenem for injection.

2.4 Patients with

Renal Impairment Ertapenem for injection may be used for the treatment of infections in adult patients with renal impairment. In patients whose creatinine clearance is >30 mL/min/1.73 m 2, no dosage adjustment is necessary. Adult patients with severe renal impairment (creatinine clearance ≤30 mL/min/1.73 m 2 ) and end-stage renal disease (creatinine clearance ≤10 mL/min/1.73 m 2 ) should receive 500 mg daily. A supplementary dose of 150 mg is recommended if ertapenem is administered within 6 hours prior to hemodialysis. There are no data in pediatric patients with renal impairment.

2.5 Patients on

Hemodialysis When adult patients on hemodialysis are given the recommended daily dose of 500 mg of ertapenem for injection within 6 hours prior to hemodialysis, a supplementary dose of 150 mg is recommended following the hemodialysis session. If ertapenem for injection is given at least 6 hours prior to hemodialysis, no supplementary dose is needed. There are no data in patients undergoing peritoneal dialysis or hemofiltration. There are no data in pediatric patients on hemodialysis. When only the serum creatinine is available, the following formula Cockcroft and Gault equation: Cockcroft DW, Gault MH. Prediction of creatinine clearance from serum creatinine. Nephron. 1976 may be used to estimate creatinine clearance. The serum creatinine should represent a steady state of renal function.

Males: (weight in kg) × (140-age in years × serum creatinine (mg/100 mL) Females: x (value calculated for males)

2.6 Patients with

Hepatic Impairment No dose adjustment recommendations can be made in patients with hepatic impairment.

2.7 Preparation and

Reconstitution for Administration Vials Adults and pediatric patients 13 years of age and older Preparation for intravenous administration: DO NOT MIX OR CO-INFUSE ERTAPENEM FOR INJECTION WITH OTHER MEDICATIONS. DO NOT USE DILUENTS CONTAINING DEXTROSE (α-D-GLUCOSE). ERTAPENEM FOR INJECTION MUST BE RECONSTITUTED AND THEN DILUTED PRIOR TO ADMINISTRATION. Reconstitute the contents of a 1 gram vial of ertapenem for injection with 10 mL of one of the following: Water for Injection, 0.9% Sodium Chloride Injection or Bacteriostatic Water for Injection, using a syringe equipped with a 21-gauge or smaller diameter needle.

NOTE: Use with a needleless IV system is not recommended. Shake well to dissolve and immediately transfer contents of the reconstituted vial to 50 mL of 0.9% Sodium Chloride Injection. Complete the infusion within 6 hours of reconstitution.

Preparation for intramuscular administration: ERTAPENEM FOR INJECTION MUST BE RECONSTITUTED PRIOR TO ADMINISTRATION. Reconstitute the contents of a 1 gram vial of ertapenem for injection with 3.2 mL of 1.0% lidocaine HCl injection Refer to the prescribing information for lidocaine HCl. ( without epinephrine ). Shake vial thoroughly to form solution. Immediately withdraw the contents of the vial and administer by deep intramuscular injection into a large muscle mass (such as the gluteal muscles or lateral part of the thigh). The reconstituted IM solution should be used within 1 hour after preparation.

Preparation for intramuscular administration: ERTAPENEM FOR INJECTION MUST BE RECONSTITUTED PRIOR TO ADMINISTRATION. Reconstitute the contents of a 1 gram vial of ertapenem for injection with 3.2 mL of 1.0% lidocaine HCl injection ( without epinephrine ). Shake vial thoroughly to form solution.
