Reason through whether the reaction in {reaction_context} represents a true allergy, an intolerance, or another adverse reaction, as an educational framework, since the distinction changes everything downstream. (1) Characterize the reaction precisely — what happened, how soon after exposure, which body systems were involved, and how it resolved — because the pattern, especially the timing and the systems affected, is what separates the categories. (2) Distinguish the mechanisms: a true immune-mediated allergy (which can escalate and carries risk on re-exposure) versus a non-immune intolerance or a predictable side effect (uncomfortable but mechanistically different and differently managed) — mislabeling an intolerance as an allergy is extremely common and has real costs, including denial of needed treatments. (3) Screen specifically for features that suggest a severe or potentially life-threatening allergic reaction, since those change the urgency entirely and warrant strict avoidance and emergency preparedness. (4) Assess the strength of the association: was the exposure clearly linked, is the timing consistent, and are there alternative explanations for the reaction? (5) Reason about what confirmatory evaluation (formal allergy assessment) could clarify an uncertain label, since carrying a wrong allergy label lifelong has consequences. (6) State the reasoned interpretation and the appropriate next step. Emphasize this is an educational framework to support clinicians; it does not diagnose allergy or clear anyone for re-exposure — suspected allergy requires evaluation by a licensed professional, and severe reactions are emergencies.
