A primary care provider can manage most cases of acute urticaria. If a trigger is easily identified and avoidance leads to resolution, then referral is not necessary. If an allergic trigger is suspected but not easily identified, then referral to an allergy specialist is warranted. [71] Similarly, if avoidance of a trigger does not lead to resolution or if the patient does not respond well to antihistamines, then referral to an allergist or dermatologist is warranted. [71]
