Ceftriaxone Precautions

Serious side effects have been reported with ceftriaxone including:

    • chest pain
    • swelling of the face, eyes, lips, tongue, arms, or legs
    • difficulty breathing or swallowing
    • fainting
    • rash
  • diarrhea. Diarrhea is a common problem caused by antibiotics, and it usually ends when the antibacterial is discontinued. Sometimes after starting treatment with antibiotics, patients can develop watery and bloody stools (with or without stomach cramps and fever) even as late as 2 or more months after having taken their last dose of the antibacterial. If diarrhea is severe or lasts more than 2 or 3 days, contact your doctor, as this may be a sign of an infection of the bowels.
  • superinfection. Ceftriaxone should not be used for extended periods. Prolonged use can lead to the growth of dangerous organisms that are resistant or unresponsive to this medication. Take ceftriaxone for the duration prescribed by your doctor.
  • bleeding abnormalities. Your health care provider may want to monitor lab tests that show how well your blood is able to clot or that measure your tendency to bleed. Any abnormalities or irregularities that may occur may be more common in those with kidney dysfunction.
  • nervous system disturbances. Some may experience nervous symptom abnormalities such as a seizure or disturbances of consciousness (confusion, hallucinations, stupor, coma) when the dose of ceftriaxone exceeds the recommended dose, especially in the presence of kidney dysfunction.

Do not take ceftriaxone in the following situations:

  • in those who are allergic to ceftriaxone or to any of its ingredients

  • in neonates if they require (or are expected to require) treatment with calcium-containing IV solutions, including continuous calcium-containing infusions such as parenteral nutrition
