Duration of Observation for Detecting a Biphasic Reaction in Anaphylaxis: A Meta-Analysis

Conclusions: An observation time of ≥6 h after resolution of an initial anaphylaxis symptom can exclude recurrence of a secondary reaction in #x3e; 95% of patients. Although longer observation periods resulted in the detection of more biphasic reactions, 6–12 h of observation time would be practical, supporting current relevant gu idelines.Int Arch Allergy Immunol
