Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of imipramine in the elderly. However, elderly patients are more likely to have age-related kidney, liver, or heart problems, which may require caution and an adjustment in the dose for patients receiving imipramine.
