- Antibiotic, Cephalosporin (First Generation)
Inhibits bacterial cell wall synthesis by binding to one or more of the penicillin-binding proteins (PBPs) which in turn inhibits the final transpeptidation step of peptidoglycan synthesis in bacterial cell walls, thus inhibiting cell wall biosynthesis. Bacteria eventually lyse due to ongoing activity of cell wall autolytic enzymes (autolysins and murein hydrolases) while cell wall assembly is arrested.

Off Label Uses
Catheter-related bloodstream infections (adults)
IDSA clinical practice guidelines state that the use of cefazolin in catheter-related bloodstream infections may be appropriate when the infection is due to methicillin-susceptible S. aureus or methicillin-susceptible, coagulase-negative Staphylococcus species.
Community-acquired pneumonia (children)
Following clinical guideline recommendations on the management of CAP reduces the incidence of morbidity and mortality related to pneumonia. IV cefazolin is a preferred agent for treatment of children with CAP due to MSSA. To potentially reduce morbidity and mortality, therapy should be initiated in the inpatient setting.
Based on the American Heart Association (AHA) guidelines for the prevention of infective endocarditis, cefazolin is effective and recommended for administration to patients with certain cardiac conditions who are unable to take oral medication or are allergic to penicillins or ampicillin and unable to take oral medication to provide prophylaxis against infective endocarditis associated with dental or respiratory tract procedures.
Prophylaxis in patients with prosthetic joint implants undergoing dental procedures which produce bacteremia
Although currently not recommended for routine use prior to dental procedures in patients with prosthetic joint implants to prevent prosthetic joint infection as stated within the American Academy of Orthopaedic Surgeons/American Dental Association Prevention of Orthopaedic Implant Infection in Patients Undergoing Dental Procedures guidelines and a subsequent report of the American Dental Association Council on Scientific Affairs, if deemed to be necessary for select patients at risk for prosthetic joint infection (eg, history of complications associated with joint replacement surgery), antibiotic prophylaxis may be considered. Dentists planning invasive oral procedures should therefore consult with the patient's orthopedic surgeon to determine the risk associated with infection and the need for antibiotics. Based on a retired advisory statement from the American Dental Association and American Academy of Orthopaedic Surgeons, the use of cefazolin (or ampicillin) was suggested for patients not allergic to penicillin and unable to take oral medications [ADA/AAOS 2003].
Skin and soft tissue necrotizing infections
Based on the Infectious Diseases Society of America (IDSA) guidelines for the diagnosis and management of skin and soft tissue infections (SSTI), cefazolin, is an effective and recommended alternative for treatment of necrotizing infections of the skin, fascia, and muscle due to methicillin-sensitive S. aureus.
Surgical site infection
Based on the Infectious Diseases Society of America (IDSA) guidelines for the diagnosis and management of skin and soft tissue infections (SSTI), cefazolin is an effective and recommended option for treatment of surgical site infections occurring after surgery of the trunk or extremity (away from axilla or perineum). Systemic antibacterials are not routinely indicated for surgical site infections, but may be beneficial (in conjunction with suture removal plus incision and drainage) in patients with significant systemic response (eg, temperature >38.5ºC, heart rate >110 beats per minute, erythema/induration extending >5 cm from incision, WBC >12,000/mm3).
Hypersensitivity to cefazolin, other cephalosporin antibiotics, penicillins, other beta-lactams, or any component of the formulation.
Usual dosage range: IM, IV: 1 to 1.5 g every 8 hours, depending on severity of infection; maximum: 12 g daily
Catheter-related bloodstream infections (off-label use): IV: 2 g every 8 hours (IDSA [Mermel 2009])
Cholecystitis, mild-to-moderate: IV: 1 to 2 g every 8 hours for 4 to 7 days (provided source controlled)
Endocarditis, prophylaxis (off-label use): Dental and upper respiratory procedures: IM, IV: 1 g 30 to 60 minutes before procedure. Intramuscular injections should be avoided in patients who are receiving anticoagulant therapy. In these circumstances, orally administered regimens should be given whenever possible. Intravenously administered antibiotics should be used for patients who are unable to tolerate or absorb oral medications.
Note: American Heart Association (AHA) guidelines now recommend prophylaxis only in patients undergoing invasive procedures and in whom underlying cardiac conditions may predispose to a higher risk of adverse outcomes should infection occur. As of April 2007, routine prophylaxis for GI/GU procedures is no longer recommended by the AHA.
Endocarditis, treatment: IV:
Manufacturer’s labeling: 1 to 1.5 g every 6 hours
Alternate dosing (AHA [Baddour 2015]): MSSA in penicillin-allergic (nonanaphylactoid) patients:
Native valve: 2 g every 8 hours for 6 weeks
Prosthetic valve: 2 g every 8 hours for a minimum of 6 weeks (in combination with rifampin for entire course of therapy and gentamicin for the first 2 weeks)
Group B streptococcus (neonatal prophylaxis): IV: 2 g once, then 1 g every 8 hours until delivery (CDC 2010)
Intra-abdominal infection, complicated, community-acquired, mild-to-moderate (in combination with metronidazole): IV: 1 to 2 g every 8 hours for 4 to 7 days (provided source controlled)
Moderate to severe infections: IV: 500 mg to 1 g every 6 to 8 hours
Mild infection with gram-positive cocci: IV: 250 to 500 mg every 8 hours
Osteomyelitis, native vertebral (off-label dose): Staphylococci (oxacillin-susceptible): IV: 1 to 2 g every 8 hours for 6 weeks (IDSA [Berbari 2015])
Manufacturer’s labeling: IM, IV: 1 to 2 g initiated 30 to 60 minutes prior to surgery; may repeat after 2 hours if procedure is lengthy with 500 mg to 1 g intraoperatively, followed by 500 mg to 1 g every 6 to 8 hours for 24 hours postoperatively.
Guideline recommendations (off-label): IV: Note: For most surgical procedures, joint clinical practice guidelines from the American Society of Health-System Pharmacists, Infectious Diseases Society of America, Surgical Infection Society, and Society for Healthcare Epidemiology of America (ASHP/IDSA/SIS/SHEA) recommend a dose of 2 g within 60 minutes prior to surgical incision (for nonobese patients weighing <120 kg). For procedures requiring anaerobic coverage (eg, appendectomy, small bowel surgery with intestinal obstruction, colon procedures), combine cefazolin with metronidazole as an alternative to a second generation cephalosporin with anaerobic activity (eg, cefoxitin or cefotetan). Cefazolin doses may be repeated intraoperatively in 4 hours if procedure is lengthy or if there is excessive blood loss (Bratzler 2013).
Obesity: The ASHP/IDSA/SIS/SHEA guidelines recommend that for patients weighing ≥120 kg, a dose of 3 g within 60 minutes prior to surgical incision should be administered (Bratzler 2013). Alternatively, for patients with BMI >40 kg/m2, a single 2 g dose may be sufficient for common general surgical procedures lasting <5 hours; patients enrolled in this multigroup study had a BMI up to a group mean of 55.7 kg/m2 (Ho 2012).
Cardiothoracic surgery: IV: 1 g (see "Note") initiated 30 to 60 minutes prior to surgery (usually at the time of anesthetic induction); repeat dose if the duration of operation exceeds 3 hours (Hillis 2011). The ASHP/IDSA/SIS/SHEA guidelines recommend the use of 2 g (single dose) administered within 60 minutes prior to surgical incision (Bratzler 2013). May either continue for ≤48 hours postoperatively or administer as a single dose preoperatively (may be preferred due to reduced cost and potential for antimicrobial resistance) (Bratzler 2013; Bucknell 2000; Douglas 2011; Edwards 2006; Hillis 2011).
Note: For patients weighing >60 kg, the Society of Thoracic Surgeons recommends a preoperative dose of 2 g administered within 60 minutes of skin incision. If the surgical incision remains open in the operating room, follow with 1 g every 3 to 4 hours unless cardiopulmonary bypass is to be discontinued within 4 hours then delay administration (Engelman 2007).
Peritonitis, treatment (off-label route; Li 2010): Intraperitoneal:
Intermittent exchange: 15 mg/kg per exchange every 24 hours in the long dwell (≥6 hours)
Continuous exchange: Loading dose: 500 mg per liter of dialysate. Maintenance: 125 mg per liter of dialysate.
Note: If patient has residual renal function (eg, >100 mL/day urine output), empirically increase each dose by 25%
Automated peritoneal dialysis: 20 mg/kg every 24 hours in the long day dwell; Note: Guidelines suggest nighttime levels of intraperitoneal cefazolin may fall below the MIC of most organisms and adding cefazolin to each exchange may be warranted
Pneumococcal pneumonia: IV: 500 mg every 12 hours
Prophylaxis in total joint replacement patients undergoing dental procedures which produce bacteremia (off-label use): IM, IV: 1 g 1 hour prior to procedure (ADA/AAOS 2003). Note: In general, patients with prosthetic joint implants do not require prophylactic antibiotics prior to dental procedures. In planning an invasive oral procedure, dental consultation with the patient's orthopedic surgeon may be advised to review the risks of infection (Sollecito 2015).
Prosthetic joint infection, Staphylococcal (oxacillin-susceptible): IV: 1 to 2 g every 8 hours for 2 to 6 weeks (in combination with rifampin) followed by oral antibiotic treatment and suppressive regimens (Osmon 2013)
Severe infection: IV: 1 to 1.5 g every 6 hours
Skin and soft tissue infection due to MSSA, including pyomyositis: IV: 1 g every 8 hours for 7 to 14 days; treat pyomyositis for 14 to 21 days (IDSA [Stevens 2014])
Skin and soft tissue necrotizing infection due to MSSA (off-label use): IV: 1 g every 8 hours; continue until further debridement is not necessary, patient has clinically improved, and patient is afebrile for 48 to 72 hours (IDSA [Stevens 2014])
Streptococcal skin infections: IV: 1 g every 8 hours (IDSA [Stevens 2014])
Surgical site infection (trunk or extremity [away from axilla or perineum]) (off-label use): IV: 500 mg to 1 g every 8 hours (IDSA [Stevens 2014])

Endocarditis, prophylaxis (off-label use): Dental and upper respiratory procedures: Infants, Children, and Adolescents: IM, IV: 50 mg/kg 30 to 60 minutes before procedure; maximum dose: 1,000 mg (AHA [Wilson 2007]). Note: AHA guidelines (Baltimore 2015) limit the use of prophylactic antibiotics to patients at the highest risk for infective endocarditis (IE) or adverse outcomes (eg, prosthetic heart valves, patients with previous IE, unrepaired cyanotic congenital heart disease, repaired congenital heart disease with prosthetic material or device during first 6 months after procedure, repaired congenital heart disease with residual defects at the site or adjacent to site of prosthetic patch or device, and heart transplant recipients with cardiac valvulopathy).
Endocarditis, treatment (off-label): Children and Adolescents: IV: 100 mg/kg/day in divided doses every 8 hours; usual adult dose: 2,000 mg/dose; maximum daily dose: 12 g/day; treat for at least 4 weeks; longer durations may be necessary; may use with or without gentamicin (AHA [Baltimore 2015])
Perioperative prophylaxis (off-label use): Children ≥1 year: IV: Note: For most surgical procedures, joint clinical practice guidelines from the American Society of Health-System Pharmacists, Infectious Diseases Society of America, Surgical Infection Society, and Society for Healthcare Epidemiology of America (ASHP/IDSA/SIS/SHEA) recommend a dose of 30 mg/kg (maximum dose: 2,000 mg) administered within 60 minutes prior to surgical incision. For procedures requiring anaerobic coverage (eg, appendectomy, small bowel surgery with intestinal obstruction, colon procedures), combine cefazolin with metronidazole as an alternative to a second generation cephalosporin with anaerobic activity (eg, cefoxitin or cefotetan). Cefazolin doses may be repeated intraoperatively in 4 hours if procedure is lengthy or if there is excessive blood loss (Bratzler 2013).
Peritonitis, treatment (off-label route; Warady 2012): Infants, Children, and Adolescents: Intraperitoneal:

Skin and soft tissue necrotizing infections due to MSSA (off-label use): Infants and Children: IV: 33 mg/kg every 8 hours; continue until further debridement is not necessary, patient has clinically improved, and patient is afebrile for 48 to 72 hours (IDSA [Stevens 2014])
Streptococcal skin infections: Infants and Children: IV: 33 mg/kg every 8 hours (IDSA [Stevens 2014])
Dosing: Renal Impairment
CrCl ≥55 mL/minute: No dosage adjustment necessary
CrCl 35 to 54 mL/minute: Administer full dose in intervals of ≥8 hours
CrCl 11 to 34 mL/minute: Administer 50% of usual dose every 12 hours

Intermittent hemodialysis (IHD) (administer after hemodialysis on dialysis days): Dialyzable (20% to 50%): 500 mg to 1 g every 24 hours or use 1 to 2 g every 48 to 72 hours (Heintz 2009) or 15 to 20 mg/kg (maximum dose: 2 g) after dialysis 3 times weekly (Ahern 2003; Sowinski 2001) or 2 g after dialysis if next dialysis expected in 48 hours or 3 g after dialysis if next dialysis is expected in 72 hours (Stryjewski 2007).
Note: Dosing dependent on the assumption of 3 times weekly, complete IHD sessions.
Peritoneal dialysis (PD): IV: 500 mg every 12 hours
Continuous renal replacement therapy (CRRT) (Heintz 2009; Trotman 2005): Drug clearance is highly dependent on the method of renal replacement, filter type, and flow rate. Appropriate dosing requires close monitoring of pharmacologic response, signs of adverse reactions due to drug accumulation, as well as drug concentrations in relation to target trough (if appropriate). The following are general recommendations only (based on dialysate flow/ultrafiltration rates of 1 to 2 L/hour and minimal residual renal function) and should not supersede clinical judgment:
CVVH: Loading dose of 2 g followed by 1 to 2 g every 12 hours
CVVHD/CVVHDF: Loading dose of 2 g followed by either 1 g every 8 hours or 2 g every 12 hours. Note: Dosage of 1 g every 8 hours results in similar steady-state concentrations as 2 g every 12 hours and is more cost effective (Heintz 2009).
Infants >1 month, Children, and Adolescents:
CrCl >70 mL/minute: No dosage adjustment necessary.
CrCl 40 to 70 mL/minute: 60% of usual daily dose divided every 12 hours
CrCl 20 to 40 mL/minute: 25% of usual daily dose divided every 12 hours
CrCl 5 to 20 mL/minute: 10% of usual daily dose every 24 hours
Intermittent hemodialysis (IHD): 25 mg/kg per dose every 24 hours (Aronoff 2007)
Peritoneal dialysis (PD): 25 mg/kg per dose every 24 hours (Aronoff 2007)
Continuous renal replacement therapy (CRRT): 25 mg/kg per dose every 8 hours (Aronoff 2007)
Dosing: Hepatic Impairment

Dilute 500 mg vial with 2 mL SWFI and 1 g vial with 2.5 mL SWFI; reconstituted solution may be directly injected after further dilution with 5 mL SWFI or further diluted for IV administration in 50 to 100 mL compatible solution (eg, D5W, NS); 10 g vial may be diluted with 45 mL to yield 1 g/5 mL or 96 mL to yield 1 g/10 mL.
IM: Inject deep IM into large muscle mass.
IV: Inject direct IV over 3 to 5 minutes or may infuse as an intermittent infusion over 30 to 60 minutes.
Some penicillins (eg, carbenicillin, ticarcillin and piperacillin) have been shown to inactivate aminoglycosides in vitro. This has been observed to a greater extent with tobramycin and gentamicin, while amikacin has shown greater stability against inactivation. Concurrent use of these agents may pose a risk of reduced antibacterial efficacy in vivo, particularly in the setting of profound renal impairment. However, definitive clinical evidence is lacking. If combination penicillin/aminoglycoside therapy is desired in a patient with renal dysfunction, separation of doses (if feasible), and routine monitoring of aminoglycoside levels, CBC, and clinical response should be considered.

Concerns related to adverse effects:
• Elevated INR: May be associated with increased INR, especially in nutritionally-deficient patients, prolonged treatment, hepatic or renal disease.
• Hypersensitivity reactions: Hypersensitivity reactions, including anaphylaxis, may occur. If an allergic reaction occurs, discontinue treatment and institute appropriate supportive measures.
• Penicillin allergy: Use with caution in patients with a history of penicillin allergy.
• Superinfection: Prolonged use may result in fungal or bacterial superinfection, including C. difficile-associated diarrhea (CDAD) and pseudomembranous colitis; CDAD has been observed >2 months postantibiotic treatment.
• Gastrointestinal disease: Use with caution in patients with a history of gastrointestinal disease, particularly colitis.
• Renal impairment: Use with caution in patients with renal impairment; dosage adjustment required.
• Seizure disorders: Use with caution in patients with a history of seizure disorder; high levels, particularly in the presence of renal impairment, may increase risk of seizures.
Concurrent drug therapy issues:
• Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.
Renal function periodically, hepatic function tests, CBC; monitor for signs of anaphylaxis during first dose
Pregnancy Risk Factor
Adverse effects have not been observed in animal reproduction studies. Cefazolin crosses the placenta. Adverse events have not been reported in the fetus following administration of cefazolin prior to cesarean section. Cefazolin is recommended for group B streptococcus prophylaxis in pregnant patients with a nonanaphylactic penicillin allergy. It is also one of the antibiotics recommended for prophylactic use prior to cesarean delivery and may be used in certain situations prior to vaginal delivery in women at high risk for endocarditis.
Due to pregnancy-induced physiologic changes, the pharmacokinetics of cefazolin are altered. The half-life is shorter, the AUC is smaller, and the clearance and volume of distribution are increased.
• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
• Patient may experience diarrhea or lack of appetite. Have patient report immediately to prescriber severe nausea, severe vomiting, bruising, bleeding, thrush, chills, pharyngitis, loss of strength and energy, seizures, injection site pain or irritation, urinary retention, change in amount of urine passed, vaginitis, signs of Stevens-Johnson syndrome/toxic epidermal necrolysis (red, swollen, blistered, or peeling skin [with or without fever]; red or irritated eyes; or sores in mouth, throat, nose, or eyes), or signs of Clostridium difficile (C. diff)-associated diarrhea (abdominal pain or cramps, severe diarrhea or watery stools, or bloody stools) (HCAHPS).
• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
