To increase awareness of the potential for recurrence in patients with a history of DRESS syndrome and provide a brief review of the clinical characteristics, diagnosis, and management of this disease process.

A case of recurrent DRESS triggered by a structurally unrelated drug is presented, followed by discussion of the clinical characteristics, diagnosis, and management. Clinical pearls and pitfalls are emphasized for the practicing allergist, clinical immunologist, and fellow-in-training.
