Description
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.
High blood pressure: The recommended adult dose of doxazosin ranges from 1 mg to 16 mg daily, depending on the person’s needs and circumstances. The recommended initial dose of doxazosin for blood pressure is 1 mg once daily. This dose can be slowly increased to a maximum of 16 mg once daily.
BPH: The recommended dose for symptoms of enlarged prostate ranges from 1 mg to 8 mg once daily, depending on the person’s needs and circumstances. The recommended initial dose of doxazosin for BPH is 1 mg once daily. This dose can be doubled every 1 to 2 weeks to a maximum of 8 mg once daily.
