The diagnosis is usually apparent from the history and physical examination. A history of medication exposure is usually obtained. Even when a supporting history is not obtained, the clinical picture alone is enough to strongly suggest the diagnosis. A predictable, rapid resolution of symptoms following treatment confirms the diagnosis. Failure to improve, however, should prompt the clinician to consider alternative diagnosis.
