What Is Ceftriaxone and How Does It Work?

Ceftriaxone is not recommended for use in newborns with high blood bilirubin levels and premature infants due to increased risk of side effects. Ask the doctor or pharmacist for details.

Ceftriaxone may also be used before dental procedures in people with certain heart conditions (such as artificial heart valves) to help prevent serious infection of the heart (bacterial endocarditis).

Cautions

  • 10-g pharmacy bulk package should not be used for direct infusion
  • Immune-mediated hemolytic anemia reported; if patient develops anemia while on ceftriaxone, stop antibiotic until etiology determined; severe hemolytic anemia, including fatalities, reported in both adults and children
  • May increase INR, especially in nutritionally deficient patients, hepatic or renal disease or prolonged treatment
  • Dosage must be adjusted in severe renal insufficiency (high dosages may cause central nervous system [CNS] toxicity)
  • Superinfections and promotion of nonsusceptible organisms may occur with prolonged use or repeated therapy
  • Use with caution in patients with history of penicillin allergy
  • Use with caution in patients with history of gastrointestinal (GI) disease, especially colitis
  • Use with caution in breastfeeding women; drug may displace bilirubin from albumin-binding sites, increasing risk of kernicterus
  • Abnormal gallbladder sonograms reported, possibly the result of ceftriaxone-calcium precipitates; discontinue if signs or symptoms of gallbladder disease occur
  • Ceftriaxone-calcium precipitates in urinary tract observed in patients receiving ceftriaxone; may be detected as sonographic abnormalities; patients may be asymptomatic or may develop symptoms of urolithiasis, and ureteral obstruction and post-renal acute renal failure; appears to be reversible upon discontinuation of therapy and institution of appropriate management; ensure adequate hydration; discontinue therapy in patients who develop signs and symptoms suggestive of urolithiasis, oliguria or renal failure and/or the sonographic findings
  • Clostridium difficile-associated diarrhea (CDAD reported with use of nearly all antibacterial agents, including ceftriaxone; If CDAD suspected or confirmed, may consider discontinuing ongoing antibacterial use not directed against C. difficile; institute appropriate fluid and electrolyte management, protein supplementation, antibacterial treatment of C. difficile, and surgical evaluation
  • Pancreatitis secondary to biliary obstruction reported rarely; use with caution in patients with gallbladder, biliary tract, liver, or pancreatic disease and patients with history of penicillin hypersensitivity
  • Use with caution in patients with history of gastrointestinal (GI) disease (e.g., colitis)

Pregnancy and Lactation

  • Ceftriaxone may be acceptable for use during pregnancy. Either animal studies show no risk but human studies are not available or animal studies showed minor risks and human studies were done and showed no risk
  • Ceftriaxone enters breast milk in low concentrations. Use with caution in breastfeeding women. Ceftriaxone may displace bilirubin from albumin-binding sites, increasing the risk of kernicterus.
