3.1Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
Adults Receiving INVANZ as a Treatment Regimen
Clinical trials enrolled 1954 patients treated with INVANZ; in some of the clinical trials, parenteral therapy was followed by a switch to an appropriate oral antimicrobial
In patients treated for complicated intra-abdominal infections, death occurred in 4.7% (15/316) of patients receiving INVANZ and 2.6% (8/307) of patients receiving comparator drug. These deaths occurred in patients with significant co-morbidity and/or severe baseline infections. Deaths were considered unrelated to study drugs by investigators.
In clinical trials, seizure was reported during study therapy plus 14-day follow-up period in 0.5% of patients treated with INVANZ, 0.3% of patients treated with piperacillin/tazobactam and 0% of patients treated with ceftriaxone

In a clinical trial for the treatment of diabetic foot infections in which 289 adult diabetic patients were treated with INVANZ, the adverse experience profile was generally similar to that seen in previous clinical trials.
Prophylaxis of Surgical Site Infection following Elective Colorectal Surgery
In a clinical trial in adults for the prophylaxis of surgical site infection following elective colorectal surgery in which 476 patients received a 1 g dose of INVANZ 1 hour prior to surgery and were then followed for safety 14 days post-surgery, the overall adverse experience profile was generally comparable to that observed for INVANZ in previous clinical trials.
Additional adverse experiences that were reported in this prophylaxis trial with INVANZ, regardless of causality, with an incidence >0.5% within each body system are listed below:
Gastrointestinal Disorders: C. difficile infection or colitis, dry mouth, hematochezia
General Disorders and Administration Site Condition: crepitations
Infections and Infestations: cellulitis, abdominal abscess, fungal rash, pelvic abscess
Injury, Poisoning and Procedural Complications: incision site complication, incision site hemorrhage, intestinal stoma complication, anastomotic leak, seroma, wound dehiscence, wound secretion

Gastrointestinal Disorders: nausea
General Disorders and Administration Site Condition: hypothermia, chest pain, upper abdominal pain; infusion site pruritus, induration, phlebitis, swelling, and warmth

3.2Post-Marketing Experience
The following additional adverse reactions have been identified during the post-approval use of INVANZ. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
Gastrointestinal Disorders: teeth staining
Immune System Disorders: anaphylaxis including anaphylactoid reactions
Musculoskeletal and Connective Tissue Disorders: muscular weakness

3.3Adverse Laboratory Changes in Clinical Trials
Adults Receiving INVANZ as Treatment Regimen
Laboratory adverse experiences that were reported during therapy in ≥2.0% of adult patients treated with INVANZ in clinical trials are presented in
Additional laboratory adverse experiences that were reported during therapy in >0.1% of patients treated with INVANZ in clinical trials include: increases in serum creatinine, serum glucose, BUN, total, direct and indirect serum bilirubin, serum sodium and potassium, PT and PTT; decreases in serum potassium, serum albumin, WBC, platelet count, and segmented neutrophils.
In a clinical trial for the treatment of diabetic foot infections in which 289 adult diabetic patients were treated with INVANZ, the laboratory adverse experience profile was generally similar to that seen in previous clinical trials.
Prophylaxis of Surgical Site Infection following Elective Colorectal Surgery
In a clinical trial in adults for the prophylaxis of surgical site infection following elective colorectal surgery in which 476 patients received a 1 g dose of INVANZ 1 hour prior to surgery and were then followed for safety 14 days post-surgery, the overall laboratory adverse experience profile was generally comparable to that observed for INVANZ in previous clinical trials.
Pediatric Patients Receiving INVANZ as a Treatment Regimen
Laboratory adverse experiences that were reported during therapy in ≥2.0% of pediatric patients treated with INVANZ in clinical trials are presented in
Additional laboratory adverse experiences that were reported during therapy in >0.5% of patients treated with INVANZ in clinical trials include: alkaline phosphatase increased, eosinophil count increased, platelet count increased, white blood cell count decreased and urine protein present.
4OVERDOSAGE
No specific information is available on the treatment of overdosage with INVANZ. Intentional overdosing of INVANZ is unlikely. Intravenous administration of INVANZ at a dose of 2 g over 30 min or 3 g over 1-2h in healthy adult volunteers resulted in an increased incidence of nausea. In clinical trials in adults, inadvertent administration of three 1 g doses of INVANZ in a 24 hour period resulted in diarrhea and transient dizziness in one patient. In pediatric clinical trials, a single intravenous dose of 40 mg/kg up to a maximum of 2 g did not result in toxicity.
In the event of an overdose, INVANZ should be discontinued and general supportive treatment given until renal elimination takes place.
INVANZ can be removed by hemodialysis; the plasma clearance of the total fraction of ertapenem was increased 30% in subjects with end-stage renal disease when hemodialysis (4 hour session) was performed immediately following administration. However, no information is available on the use of hemodialysis to treat overdosage.
