Doxazosin

Drug Details

Doxazosin, known by its brand name Cardura, is a medication primarily used to manage high blood pressure (hypertension) and symptoms of an enlarged prostate, or benign prostatic hyperplasia (BPH), in men. As an alpha-1 blocker, it functions by relaxing blood vessels, which facilitates easier blood flow and helps lower blood pressure. This reduction in blood pressure can significantly decrease the risk of strokes, heart attacks, and kidney issues. For BPH, Doxazosin helps alleviate symptoms like difficulty starting urination, a weak urine stream, and frequent or urgent urination, including nighttime occurrences, by relaxing the muscles in the prostate and bladder. The medication is available as an immediate-release tablet for both conditions, while Cardura XL, an extended-release form, is approved for BPH treatment only. Common side effects may include low blood pressure, dizziness, and fatigue. Always consult with a healthcare provider before starting any new medication.
