Doxazosin belongs to a class of drugs known as alpha-1 adrenergic blockers, which ease symptoms of an enlarged prostate and manage elevated blood pressure. This prescription medication is often recommended for use in conjunction with other treatments for the long term. Its active ingredient, Doxazosin mesylate, is usually taken once daily, with or without food. Follow your doctor’s instructions carefully to avoid side effects, such as dizziness or low blood pressure, especially during the initial period of treatment with the drug or when making dosage adjustments.

Doxazosin is a selective α₁‑adrenergic receptor blocker that relaxes the smooth muscle in both blood vessels and the prostate/bladder neck. By inhibiting norepinephrine from binding to post-synaptic α₁ receptors, it causes vasodilation, thereby reducing vascular resistance and lowering blood pressure. Additionally, it eases urinary flow in benign prostatic hyperplasia by decreasing muscle tone around the urethra. Its long half‑life supports once‑daily dosing, and it does not significantly affect heart rate or cardiac output.
Common Doxazosin side effects may include:
