UNLABELLED: Life-threatening anaphylaxis developed in a 5-y-old boy with septic shock within minutes of receiving his first intravenous injection of ceftriaxone. Hypersensivity could not be demonstrated by skin testing and ceftriaxone-specific IgE. However, an in vivo, controlled, intravenous challenge was clearly positive. CONCLUSION: Clinicians should be aware of the possibility of anaphylaxis occurring with the first dose of ceftriaxone, especially since such a reaction could go unnoticed in patients with life-threatening infections and unstable vital signs.
