What is Cardura XL?

Cardura XL is an alpha-adrenergic (AL-fa ad-ren-ER-jik) blockers. This medicine relaxes your veins and arteries so that blood can more easily pass through them. It also relaxes the muscles in the prostate and bladder neck, making it easier to urinate.

Cardura XL is used to treat hypertension (high blood pressure), or to improve urination in men with benign prostatic hyperplasia (enlarged prostate).

The extended-release form of doxazosin (Cardura XL) is for use only in treating benign prostatic hyperplasia and should not be used to treat hypertension.

Cardura XL may also be used for purposes not listed in this medication guide.
