Ceftriaxone IV Fluid Compatibility

Ceftriaxone should NOT be administered with any calcium-containing IV fluids such as Ringer's solution or Hartmann's solution due to risk of particulate formation. 1

Compatible IV Fluids for Ceftriaxone

Recommended Compatible IV Fluids

  • 0.9% Sodium Chloride Solution (stable for 2 days at room temperature, 10 days refrigerated) 1
  • 5% Dextrose Solution (stable for 2 days at room temperature, 10 days refrigerated) 1
  • 10% Dextrose Solution (stable for 2 days at room temperature, 10 days refrigerated) 1

Additional Compatible IV Fluids (stable for 24 hours at room temperature)

  • Sodium Lactate (PVC container)
  • 10% Invert Sugar (glass container)
  • 5% Sodium Bicarbonate (glass container)
  • Freamine III (glass container)
  • Normosol-M in 5% Dextrose (glass and PVC containers)
  • Ionosol-B in 5% Dextrose (glass container)
  • 5% Mannitol (glass container)
  • 10% Mannitol (glass container) 1

Incompatible IV Fluids and Medications

Incompatible IV Fluids

  • Calcium-containing solutions (e.g., Ringer's solution, Hartmann's solution) 1
  • 5% Dextrose + 0.9% Sodium Chloride Solution (incompatible when refrigerated) 1
  • 5% Dextrose + 0.45% Sodium Chloride Solution (incompatible when refrigerated) 1
  • 0.45% Sodium Chloride (incompatible beyond 5 hours at 40 mg/mL concentration) 2
  • Plasma-Lyte A (incompatible beyond 8 hours at 40 mg/mL concentration) 2

Incompatible Medications

  • Vancomycin
  • Amsacrine
  • Aminoglycosides
  • Fluconazole 1

Administration Guidelines

Concentration and Preparation

  • Recommended concentrations: 10-40 mg/mL for IV infusion 1
  • Reconstitute with appropriate diluent (see compatible fluids above)
  • For 1g vial: add 9.6 mL diluent to yield approximately 100 mg/mL solution 1

Administration Method

  • Administer by IV infusion over 30 minutes (60 minutes in neonates) 1
  • When administering other incompatible drugs:
    1. Give sequentially
    2. Thoroughly flush IV lines with compatible fluid between administrations
    3. Do not physically mix or piggyback into solutions containing other antimicrobial drugs 1

Special Considerations

Metronidazole Compatibility

  • Compatible with metronidazole hydrochloride under specific conditions:
    • Concentration should not exceed 5-7.5 mg/mL metronidazole with 10 mg/mL ceftriaxone
    • Stable for 24 hours at room temperature only
    • Only in 0.9% sodium chloride or 5% dextrose in water
    • Do not refrigerate this admixture (precipitation will occur) 1

Storage After Reconstitution

  • Reconstituted solutions should be used within the stability timeframes noted above
  • After the indicated stability periods, unused portions should be discarded
  • Reconstituted solutions can be stored frozen (-20°C) in PVC or polyolefin containers for up to 26 weeks
  • Thaw frozen solutions at room temperature before use and do not refreeze 1

Common Pitfalls and Caveats

  • NEVER mix ceftriaxone with calcium-containing solutions - fatal reactions have been reported
  • Always visually inspect for particulate matter before administration
  • Recent research indicates potential incompatibility with 0.45% sodium chloride and Plasma-Lyte A at higher concentrations (40 mg/mL) beyond specific time points 2
  • Different generic versions of ceftriaxone may have varying compatibility profiles with calcium-containing products 3
  • When in doubt about compatibility, administer separately with line flushing between medications

By following these compatibility guidelines, you can ensure safe and effective administration of ceftriaxone via intravenous route.
