Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of fesoterodine in the elderly. However, elderly patients are more likely to have unwanted side effects (e.g., constipation, dizziness, dry mouth, upset stomach, or urinary tract infection), or age-related liver or kidney problems, which may require caution in patients receiving fesoterodine.
