Prostate Health
Medicines for the urinary symptoms of benign prostatic hyperplasia: alpha blockers that relax the bladder outlet, and 5-alpha-reductase inhibitors that act on prostate size itself.
Key points
- Alpha blockers can ease urinary symptoms within days; prostate-shrinking medicines work gradually and are judged over months.
- Dutasteride lowers PSA readings by roughly half, so any clinician interpreting a PSA test needs to know it is being taken.
- Inability to pass urine, blood in urine, fever with urinary pain or severe lower-abdominal pain needs prompt care.
The listings are for comparison; suitability and supply depend on clinician and pharmacy checks, stock, destination rules and any prescription requirements.
How the medicine groups differ
- Alpha blockers: tamsulosin, alfuzosin and terazosin relax smooth muscle around the prostate and bladder outlet. Dizziness and low blood pressure are the common trade-off, and terazosin is also used for high blood pressure.
- 5-alpha-reductase inhibitors: dutasteride reduces prostate volume over months rather than days.
- Combination: Jalyn pairs the two mechanisms in one capsule, for symptoms an alpha blocker alone has not settled.
What these medicines are used for
The linked condition is benign prostatic hyperplasia. Urinary symptoms still need assessment, because infection, stones and prostate cancer can present the same way. Medicines for prostate cancer are listed under oncology support, and dutasteride’s separate use in pattern hair loss sits under hair loss.
Important safety checks
Blood pressure, other urinary medicines and planned cataract surgery all bear on treatment: alpha blockers are linked to intraoperative floppy iris syndrome, which a surgeon needs warning about. Combining an alpha blocker with a medicine for erectile dysfunction can drop blood pressure further.
When to seek urgent care
Get urgent help for inability to urinate, severe lower-abdominal pain with a full bladder, visible blood in urine, fever with flank or urinary pain, fainting or a severe allergic reaction.
