Ceftriaxone Injection: Generic, Antibiotic Uses, Warnings, Side Effects, Dosage

Generic Name: ceftriaxone
Brand Names: Rocephin (discontinued brand)
Drug Class: Cephalosporins, 3rd Generation

What is ceftriaxone, and what is it used for?

Ceftriaxone is a broad spectrum third generation cephalosporin antibiotic used to treat a wide range of bacterial infections. Ceftriaxone is administered as an intramuscular (IM) or intravenous (IV) injection. Ceftriaxone is highly effective against gram-negative bacteria, and gram-positive bacteria that are resistant to the first two generations of cephalosporins.

Gram-negative bacteria are structurally different from gram-positive bacteria, and the types are identified by whether the bacteria get dyed or not in the Gram stain lab test. Ceftriaxone kills bacteria by inhibiting the synthesis of peptidoglycan, a vital constituent that provides stability to the bacterial cell wall.

The brand Rocephin has been discontinued in the U.S., however, generic ceftriaxone is available.

Ceftriaxone is used to treat the following bacterial infections:

Adult:

Off-label uses include:

  • Septic/toxic shock
  • Acute epididymitis
  • Skin and soft tissue necrotizing infection
  • Severe acute bacterial rhinosinusitis
  • Other gonococcal infections including:

Pediatric:

  • Acute bacterial otitis media
  • Meningitis
  • Serious infections other than meningitis
  • Skin and skin structure infections
  • Gonococcal infections
  • Epiglottitis (off-label)

Organisms susceptible to ceftriaxone include:

  • Anaerobic cocci, Bacteroides fragilis, Borrelia burgdorferi, Clostridium spp, Enterobacter spp, Escherichia coli, Haemophilus influenzae, Klebsiella spp, Morganella morganii, Neisseria gonorrhoeae, Neisseria meningitides, Proteus mirabilis, Providencia rettgeri, Pseudomonas spp, Serratia spp, Staphylococcus aureus, Streptococcus pneumoniae, Streptococcus pyogenes

Warnings

  • Do not treat hyperbilirubinemic (high blood level of bilirubin) neonates, especially if premature, with ceftriaxone.
  • Do not dilute ceftriaxone with solutions containing calcium. Concomitant calcium-ceftriaxone administration has a risk of fatal precipitant formation in lungs and kidneys of full term and preterm neonates.
  • Do not administer any calcium-containing IV drugs or products to infants under 28 days within 48 hours of ceftriaxone (within 5 days if the neonate is under 10 days).
  • Do not administer ceftriaxone simultaneously with calcium-containing IV solutions to infants above 28 days. Ceftriaxone and calcium may be given sequentially after thoroughly flushing the infusion lines between the infusions with a compatible fluid.
  • Do not administer ceftriaxone to patients with known hypersensitivity to cephalosporin class of antibiotics or any other ingredient of the drug.
  • Ceftriaxone must be administered with caution in patients with hypersensitivity to penicillins or any other drugs.

Common side effects of ceftriaxone include:

  • Injection site reactions (swelling, redness, pain, a hard lump, or soreness)
  • Increase in eosinophils, type of white blood cells (eosinophilia)
  • Increased blood platelets (thrombocytosis)
  • Diarrhea
  • Elevated liver transaminases
  • Low white blood cell count (leukopenia)
  • Rash
  • Increased blood urea nitrogen (BUN)
  • Pain
