Mercaptopurine (Oral Route)

Name: Mercaptopurine (Oral Route)

Geriatric

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