Doxazosin is utilized in men to address the symptoms associated with an enlarged prostate, a condition known as benign prostatic hyperplasia (BPH). These symptoms may include difficulties in urination, such as hesitation, dribbling, a weak stream, incomplete bladder emptying, painful urination, and increased urinary frequency and urgency. Doxazosin is also employed either independently or in conjunction with other medications to manage high blood pressure.

Belonging to a class of medications called alpha-blockers, doxazosin alleviates the symptoms of BPH by relaxing the muscles in the bladder and prostate. Its effect on high blood pressure is achieved by relaxing blood vessels, facilitating smoother blood flow throughout the body.

Uses and Dosage

Doxazosin is available in tablet and extended-release tablet forms for oral administration. The doxazosin tablet is typically taken with or without food once a day, either in the morning or evening. The doxazosin extended-release tablet is usually taken once a day with breakfast.

Take doxazosin at the same time every day. Take doxazosin precisely as directed—avoid taking more or less than prescribed or increasing the frequency without your doctor’s approval.

Swallow the extended-release tablets whole; do not split, chew, or crush them.

Your doctor will initiate treatment with a low dose of doxazosin, gradually increasing it, but not more than once every 1 to 2 weeks. If you miss taking doxazosin for a few days or longer, contact your doctor. In such cases, your doctor may need to restart you on the lowest dose of doxazosin and then gradually increase it.

Doxazosin effectively manages high blood pressure and the symptoms of benign prostatic hyperplasia (BPH), but it does not cure these conditions. It may take a few weeks before you feel the full benefit of doxazosin. Continue taking doxazosin even if you feel well, and do not discontinue the medication without consulting your doctor. Open communication with your healthcare provider is crucial to ensure the safe and effective use of this medication.
