Side effects of doxazosin

Doxazosin

Doxazosin is used in the treatment of high blood pressure and problems with urination which are consequences of enlarged prostate. Doxazosin can relax the blood vessels so the blood can circulate more efficiently through your arteries and veins. It also loosens up the prostate muscles so you can pass urine more easily. Doxazosin must be taken exactly as your doctor has prescribed.
