Ertapenem for injection is a penem antibacterial indicated in adult patients and pediatric patients (3 months of age and older) for the treatment of the following moderate to severe infections caused by susceptible bacteria: Complicated intra-abdominal infections. ( 1.1 ) Complicated skin and skin structure infections, including diabetic foot infections without osteomyelitis. ( 1.2 ) Community-acquired pneumonia. ( 1.3 ) Complicated urinary tract infections including pyelonephritis. ( 1.4 ) Acute pelvic infections including postpartum endomyometritis, septic abortion and post-surgical gynecologic infections. ( 1.5 ) Ertapenem for injection is indicated in adults for the prophylaxis of surgical site infection following elective colorectal surgery. ( 1.6 ) To reduce the development of drug-resistant bacteria and maintain the effectiveness of ertapenem for injection and other antibacterial drugs, ertapenem for injection should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. ( 1.7 ) 1.1 Complicated Intra-Abdominal Infections Ertapenem for injection is indicated for the treatment of adult patients and pediatric patients (3 months of age and older) with complicated intra-abdominal infections due to Escherichia coli , Clostridium clostridioforme , Eubacterium lentum , Peptostreptococcus species, Bacteroides fragilis , Bacteroides distasonis , Bacteroides ovatus , Bacteroides thetaiotaomicron , or Bacteroides …

Ertapenem for injection is contraindicated in patients with known hypersensitivity to any component of this product or to other drugs in the same class or in patients who have demonstrated anaphylactic reactions to beta-lactams. Due to the use of lidocaine HCl as a diluent, ertapenem for injection administered intramuscularly is contraindicated in patients with a known hypersensitivity to local anesthetics of the amide type. Known hypersensitivity to product components or anaphylactic reactions to β-lactams. ( 4 ) Due to the use of lidocaine HCl as a diluent, ertapenem for injection administered intramuscularly is contraindicated in patients with a known hypersensitivity to local anesthetics of the amide type. ( 4 )

Serious hypersensitivity (anaphylactic) reactions have been reported in patients receiving β-lactams. ( 5.1 ) Seizures and other central nervous system adverse experiences have been reported during treatment. ( 5.2 ) Co-administration of ertapenem for injection with valproic acid or divalproex sodium reduces the serum concentration of valproic acid potentially increasing the risk of breakthrough seizures. ( 5.3 ) Clostridioides difficile -associated diarrhea (ranging from mild diarrhea to fatal colitis): Evaluate if diarrhea occurs. ( 5.4 ) Caution should be taken when administering ertapenem for injection intramuscularly to avoid inadvertent injection into a blood vessel. ( 5.5 ) 5.1 Hypersensitivity Reactions Serious and occasionally fatal hypersensitivity (anaphylactic) reactions have been reported in patients receiving therapy with beta-lactams. These reactions are more likely to occur in individuals with a history of sensitivity to multiple allergens. There have been reports of individuals with a history of penicillin hypersensitivity who have experienced severe hypersensitivity reactions when treated with another beta-lactam. Before initiating therapy with ertapenem for injection, careful inquiry should be made concerning previous hypersensitivity reactions to penicillins, cephalosporins, other beta-lactams and other allergens. If an allergic reaction to ertapenem for injection occurs, discontinue the drug immediately. Serious anaphylactic reactions require immediate …

8.1 Pregnancy Risk Summary Available data from a small number of post-marketing cases with ertapenem for injection use in pregnancy are insufficient to inform any drug-associated risks for major birth defects, miscarriage, or adverse maternal or fetal outcomes. In animal reproduction studies after intravenous administration of ertapenem during the period of organogenesis, there was no evidence of developmental malformations in rats at systemic exposures (AUC) up to approximately 1.2 times the human exposure at the maximum recommended human dose (MRHD) and in mice at doses up to approximately 3 times the MRHD based on body surface area comparison. In pregnant rats administered ertapenem …
