What is the severity of concerns associated with Ceftriaxone (Rocephin)?

From the Guidelines

Ceftriaxone (Rocephin) is associated with a higher risk of serious adverse effects compared to oral antimicrobials, and its use is not recommended for treatment of patients with early Lyme disease in the absence of neurologic involvement or advanced atrioventricular heart block 1.

Key Points

• Ceftriaxone is a third-generation cephalosporin antibiotic used for serious bacterial infections, including meningitis, pneumonia, and septicemia.
• The typical adult dose ranges from 1-2 grams daily, usually given for 7-14 days depending on the infection type and severity.
• Ceftriaxone works by inhibiting bacterial cell wall synthesis, causing bacterial cell death, and has a long half-life allowing for once-daily dosing.
• However, ceftriaxone is not superior to oral agents and is more likely to cause serious adverse effects, making it a less preferred option for treatment of early Lyme disease without neurologic involvement or advanced atrioventricular heart block.

Considerations

• The Infectious Diseases Society of America recommends ceftriaxone as a preferred parenteral regimen for treatment of Lyme disease, but notes its potential for serious adverse effects 1.
• The American Academy of Pediatrics suggests ceftriaxone as an alternative for children who are vomiting, unable to tolerate oral medication, or unlikely to be adherent to initial doses of antibiotic for acute bacterial sinusitis 1.
• A single 50-mg/kg dose of ceftriaxone can be used for children who meet these criteria, with oral antibiotic substitution after clinical improvement is observed 1.

Recommendations

• Ceftriaxone should be used with caution and only when necessary, due to its potential for serious adverse effects.
• Oral antimicrobials are preferred for treatment of early Lyme disease without neurologic involvement or advanced atrioventricular heart block.
• Ceftriaxone may be considered for acute bacterial sinusitis in children who are vomiting, unable to tolerate oral medication, or unlikely to be adherent to initial doses of antibiotic.

From the FDA Drug Label

Interaction with Calcium-Containing Products Do not use diluents containing calcium, such as Ringer's solution or Hartmann's solution, to reconstitute ceftriaxone vials or to further dilute a reconstituted vial for IV administration because a precipitate can form Precipitation of ceftriaxone-calcium can also occur when ceftriaxone is mixed with calcium-containing solutions in the same IV administration line. Neurological Adverse Reactions Serious neurological adverse reactions have been reported during postmarketing surveillance with ceftriaxone use These reactions include encephalopathy (disturbance of consciousness including somnolence, lethargy, and confusion), seizures, myoclonus, and non-convulsive status epilepticus Clostridium difficile -Associated Diarrhea Clostridium difficile associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents, including ceftriaxone, and may range in severity from mild diarrhea to fatal colitis Hemolytic Anemia An immune mediated hemolytic anemia has been observed in patients receiving cephalosporin class antibacterials including ceftriaxone Severe cases of hemolytic anemia, including fatalities, have been reported during treatment in both adults and children.

The severity of concerns associated with Ceftriaxone (Rocephin) includes:

• Serious neurological adverse reactions such as encephalopathy, seizures, myoclonus, and non-convulsive status epilepticus 2
• Fatal colitis due to Clostridium difficile-associated diarrhea (CDAD) 2
• Severe hemolytic anemia including fatalities 2
• Overdosage leading to neurological outcomes, including encephalopathy, seizures, myoclonus, and non-convulsive status epilepticus 2

From the Research

Severity of Concerns Associated with Ceftriaxone (Rocephin)

• The severity of concerns associated with Ceftriaxone (Rocephin) includes adverse events such as cardiac arrest, anaphylactic and anaphylactoid reactions, and neutropenia 3, 4.
• Ceftriaxone was responsible for the highest number of deaths in the Iranian pharmacovigilance database, with 49 reported cases 3.
• Serious adverse events related to ceftriaxone were reported in 357 cases, accounting for 30% of all ceftriaxone-related adverse events 3.
• Risk factors for adverse events include rapid intravenous injection, unlabelled use, and previous patient history of allergic reactions to cephalosporins or penicillins 3.

Clinical Efficacy and Safety

• Ceftriaxone has been shown to be effective and safe in the treatment of various infections, including osteomyelitis, urinary tract infections, and postoperative infections 5, 6, 7.
• The clinical response to ceftriaxone was excellent in 75.6% of cases, with a pathogen eradication rate of 85.1% 5.
• Ceftriaxone was well tolerated, with minor transient effects occurring in only a few patients 7.

Rare but Serious Adverse Events

• Neutropenia is a rare but potentially life-threatening adverse event associated with ceftriaxone, particularly when used in combination with other antibiotics such as meropenem 4.
• Antibiotic-induced neutropenia can lead to severe sepsis, shock, and even death, highlighting the need for prompt recognition and treatment 4.
