In this article, we will take a closer look at what doxazosin is, how it works, its uses, and its potential side effects.

What is Doxazosin?

Doxazosin is an alpha-blocker medication that is used to treat high blood pressure (hypertension) and symptoms of an enlarged prostate (benign prostatic hyperplasia or BPH). It works by relaxing the muscles in the prostate and bladder neck, making it easier to urinate.

How Does Doxazosin Work?

Doxazosin works by blocking alpha-1 receptors in the body, which are responsible for constricting blood vessels. By blocking these receptors, doxazosin relaxes the smooth muscles in the walls of blood vessels, allowing them to widen and reducing blood pressure.

Uses of Doxazosin

Doxazosin is primarily used to treat high blood pressure and urinary problems caused by an enlarged prostate gland. It may also be used to treat other conditions as determined by a doctor.

Some common uses of doxazosin include:

  • High blood pressure
  • Benign prostatic hyperplasia (BPH)
  • Urinary problems caused by an enlarged prostate gland

Treating High Blood Pressure

Doxazosin is used to treat high blood pressure, which is a condition that occurs when the force of blood pushing against the walls of your blood vessels is too high. This can damage your blood vessels and lead to serious health problems such as heart disease, stroke, and kidney failure.
