ABSTRACT
Glatiramer acetate is one of the oldest and safest disease modifying therapies used to treat relapsing-remitting multiple sclerosis. Urticarial vasculitis is a rare complication of treatment with glatiramer acetate, having been reported by only two others previously. Here, we describe a case of normocomplementemic urticarial vasculitis diagnosed on skin punch biopsy in a patient with multiple sclerosis treated with glatiramer acetate for five years. Upon treatment with steroids and an antihistamine along with discontinuation of glatiramer acetate, the urticaria resolved.
