Discontinuation of Finasteride in Geriatric Patients
Introduction to Finasteride Discontinuation
- The American Urological Association recommends considering the discontinuation of finasteride in patients with established incontinence, as the benefits of preventing urinary retention are negated 1
- Finasteride is associated with a reduction in risk of acute urinary retention (from 5.6% to 3.3%) and reduction in need for surgical intervention (from 3.3% to 1.7%) in patients without established incontinence 1
- The primary benefits of finasteride, including reduction in risk of acute urinary retention and need for surgical intervention, are less meaningful in a patient already experiencing incontinence 1
Age-Related Factors
- Geriatric patients, such as those over 94 years old, are significantly older than populations studied in clinical trials for finasteride (most studies included men with mean ages between 62-66 years) 1
- The American Geriatrics Society recommends considering age-related factors, including altered pharmacokinetics, when prescribing finasteride to geriatric patients 1
Medication Burden and Quality of Life
- Reducing unnecessary medications is particularly important in elderly patients with cognitive impairment, such as those with Alzheimer's disease 1
- The American College of Clinical Pharmacology recommends evaluating the medication burden and potential for adverse effects and drug interactions in geriatric patients 1
- Finasteride is associated with sexual adverse effects, including erectile dysfunction (2-4% higher than placebo), decreased libido, decreased ejaculate volume, and gynecomastia, which may negatively impact quality of life 1
Discontinuation and Monitoring
- Finasteride can be stopped immediately without tapering, and no withdrawal syndrome has been documented 1
- The American Urological Association recommends monitoring for changes in urinary symptoms over 1-3 months after discontinuation of finasteride 1
- If urinary retention develops (unlikely given established incontinence), reassess the decision to discontinue finasteride 1
Alternative Management and Documentation
- The American Urological Association recommends focusing on practical management of incontinence with appropriate products and ensuring adequate hydration while managing fluid intake timing 1
- Clearly document the rationale for discontinuation in the medical record to inform other healthcare providers 1
- PSA monitoring is recommended, as PSA levels will increase after finasteride discontinuation (approximately doubling within 3-6 months) 1
