title: Delirium following fesoterodine treatment for urgency incontinence in an 89-year old man.
abstract: We describe the case of an 89-year-old man who developed delirium following the introduction of fesoterodine to treat his urgency incontinence. The patient started experiencing visual hallucinations approximately five days after starting fesoterodine 4 mg once daily. Delirium resolved after fesoterodine was stopped. Despite the apparent safe cognitive profile due to its pharmacodynamic properties, fesoterodine should be used with caution in the elderly, frail population.
