Key takeaways

  • Alpha blockers relax smooth muscle around the prostate and bladder outlet, while 5-alpha-reductase inhibitors can shrink susceptible enlarged prostates over time by changing androgen metabolism.
  • Lower urinary symptoms can come from the prostate, bladder, urethra, pelvic floor, medicines, fluid patterns, infection, stones, metabolic disease, or neurologic conditions. Similar symptoms can require different responses.
  • The decision should verify: dominant symptoms, severity, bother, retention risk, and quality-of-life goals; prostate size, PSA context, flow, residual urine, and complication history; blood pressure, dizziness, falls, cataract-surgery plans, and other medicines.
  • This page does not select a medicine, dose, combination, or discontinuation plan and does not assume urinary symptoms are caused by prostate enlargement.
  • Safety first: Seek urgent care for inability to urinate, fainting, fever with urinary symptoms, heavy bleeding, severe pain, or a serious allergic reaction. Do not stop prescribed medicine without clinician guidance.
