How does this medication work? What will it do for me?
Doxazosin belongs to the family of medications called antihypertensives, specifically the alpha-1 receptor antagonists (alpha blockers). It is used to treat mild to moderate high blood pressure. It may be used alone or in combination with other medications that treat high blood pressure. It works to control blood pressure by relaxing blood vessels.
It is also used to treat the symptoms of benign prostatic hyperplasia (BPH or enlarged prostate). It works to relax the muscles around the neck of the bladder, allowing urine to flow out more freely. You may notice an improvement in symptoms within 1 to 2 weeks.
