What is doxazosin? Doxazosin is in a group of drugs called
alpha-adrenergic blockers. Doxazosin causes the blood vessels (veins and
arteries) to relax and expand, improving blood flow. Doxazosin also relaxes
muscles in the prostate and bladder neck, making it easier to urinate. Doxazosin
is used to treat hypertension (high blood pressure) and benign prostatic
hyperplasia (enlarged prostate). Doxazosin may also be used for purposes other
than those listed in this medication guide.
