title: Urticaria from erythromycin.
abstract: We report an adverse cutaneous reaction (urticaria) due to erythromycin. A positive skin prick and leukocyte histamine release tests, as well as a positive single-blind, placebo controlled oral challenge to erythromycin, strongly suggest an IgE mediated hypersensitivity mechanism.
