Frequently asked questions
Does alfuzosin shrink the prostate?
No. It relaxes the prostate and bladder-neck muscle to improve flow; drugs like finasteride shrink it over time.
Why do I feel dizzy?
It can lower blood pressure when you stand. Get up slowly, especially at first.
Does it cause ejaculation problems?
It can, but less often than tamsulosin.
