Instructions For Use In All Patients
For Intravenous Or Intramuscular Use
DO NOT MIX OR CO-INFUSE Invanz WITH OTHER MEDICATIONS. DO NOT USE DILUENTS CONTAINING DEXTROSE (α-D-GLUCOSE).
Invanz may be administered by intravenous infusion for up to 14 days or intramuscular injection for up to 7 days. When administered intravenously, Invanz should be infused over a period of 30 minutes.
Intramuscular administration of Invanz may be used as an alternative to intravenous administration in the treatment of those infections for which intramuscular therapy is appropriate.
13 Years Of Age And Older
- The dose of Invanz 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 Invanz in patients 3 months to 12 years of age is 15 mg/kg twice daily (not to exceed 1 g/day).
- Table 1 presents treatment guidelines for Invanz.

|Infection†||Daily Dose (IV or IM) Adultsand Pediatric Patients13 yearsof age and older||Daily Dose (IV or IM) Pediatric Patients3 monthsto 12 years of age||Recommended Duration of Total Antimicrobial Treatment|
|Complicated intra-abdominal infections||1 g||15 mg/kg twice daily‡||5 to 14 days|
|Complicated skin and skin structure infections including diabetic foot infection#||1 g||1 5 mg/kg twice daily‡||7 to 14 days¶|
|Community acquired pneumonia||1 g||1 5 mg/kg twice daily‡||10 to 14 days#|
|Complicated urinary tract infections including pyelonephritis||1 g||1 5 mg/kg twice daily‡||10 to 14 days#|
|Acute pelvic infectionsincluding postpartum endomyometritis septic abortion and post-surgical gynecologic infections||1 g||1 5 mg/kg twice daily‡||3 to 10 days|
|* defined as creatinine clearance>90 mL/min/1.73 m²|
† due to the designated pathogens
‡ not to exceed 1 g/day
§ Invanz has not been studied in diabetic foot infections with concomitant osteomyelitis.
¶ adult patients with diabetic foot infections received up to 28 days of treatment (parenteral or parenteral plus oral switch therapy)
# duration includes a possible switch to an appropriate oral therapy, after at least 3 days of parenteral therapy, once clinical improvement has been demonstrated.
Prophylactic Regimen In Adults
- Table 2 presents prophylaxis guidelines for Invanz.

|Indication||Daily Dose (IV) Adults||Recommended Duration of Total Antimicrobial Treatment|
|Prophylaxisof surgical site infection following elective colorectal surgery||1 g||Single intravenousdose given 1 hour prior to surgical incision|
Patients With Renal Impairment
- Invanz 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 m², no dosage adjustment is necessary.
- Adult patients with severe renal impairment (creatinine clearance ≤30 mL/min/1.73 m²) and end-stage renal disease (creatinine clearance ≤10mL/min/1.73m²)should receive 500mg 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.
Patients On Hemodialysis
- When adult patients on hemodialysis are given the recommended daily dose of 500 mg of Invanz within 6 hours prior to hemodialysis, a supplementary dose of 150 mg is recommended following the hemodialysis session. If Invanz is given at least 6 hours prior to hemodialysis, no supplementary dose isneeded.
- 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 may be used to estimate creatinine clearance. The serum creatinine should represent a steady state of renal function.
- Males: (weight in kg) x (140-age in years) /(72)x serum creatinine (mg/100 mL)
- Females: (0.85) x(value calculated for males)
Patients With Hepatic Impairment
- No dose adjustment recommendations can be made in patients with hepatic impairment.
What drugs interact with Invanz?
- Probenecid interferes with the active tubular secretion of ertapenem, resulting in increased plasma concentrations of ertapenem. Co-administration of probenecid with ertapenem is not recommended.
- Case reports in the literature have shown that co-administration of carbapenems, including ertapenem, to patients receiving valproic acid or divalproex sodium results in a reduction of valproic acid concentrations.
- The valproic acid concentrations may drop below the therapeutic range as a result of this interaction, therefore increasing the risk of breakthrough seizures.
- Although the mechanism of this interaction is unknown, data from in vitro and animal studies suggest that carbapenems may inhibit the hydrolysis of valproic acid's glucuronide metabolite (VPA-g) back to valproic acid, thus decreasing the serum concentrations of valproic acid.
Is Invanz safe to use while pregnant or breastfeeding?
- Available data from a small number of post-marketing cases with Invanz use in pregnancy are insufficient to inform any drug-associated risks for major birth defects, miscarriage, or adverse maternal or fetal outcomes.
- Ertapenem is present in human milk. There are no data on the effects on the breastfed infant or the effects on milk production.
- The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for Invanz and any potential adverse effects on the breastfed infant from Invanz or from the underlying maternal condition.

Urinary Tract Infection (UTI)
A urinary tract infection (UTI) is an infection of the bladder, kidneys, ureters, or urethra. E. coli, a type of bacteria that lives in the bowel and near the anus, causes most UTIs. UTI symptoms include pain, abdominal pain, mild fever, urinary urgency, and frequency. Treatment involves a course of antibiotics.
Bladder Infection (Cystitis)
Bladder infection is an infection of the bladder, usually caused by bacteria or, rarely, by Candida. Certain people, including females, the elderly, men with enlarged prostates, and those with chronic medical conditions are at increased risk for bladder infection. Bladder infections are treated with antibiotics, but cranberry products and adequate hydration may help prevent bladder infections.

Candida albicans typically causes vaginal yeast infections. Bacterial infections typically cause urinary tract infections (UTIs). Thick white cottage-cheese like vaginal discharge characterizes vaginal yeast infections. Painful, frequent urination characterize urinary tract infections. Antifungal medications treat yeast infections while prescription antibiotics treat UTIs.

Urinary Tract Infection or Urinary Infection
The urinary system of your body includes two kidneys, two tubes (ureters), a urine sac (bladder) and an opening to expel the urine from the body (urethra). An infection of this system due to germs is called a urinary tract infection (UTI). UTI may be treated with antibiotics, especially if a kidney infection is involved.
