Cardura is a brand name for the medication doxazosin, which belongs to a class of drugs known as alpha blockers. It’s primarily to treat high blood pressure (hypertension) and symptoms of benign prostatic hyperplasia (BPH), a condition where the prostate gland becomes enlarged, causing urinary problems. The typical starting dose for hypertension is 1 mg once daily, usually taken at bedtime to minimize the risk of dizziness from low blood pressure. It’s important to follow your doctor’s instructions and not adjust the dosage on your own. If you have any concerns or experience side effects, it’s crucial to discuss them with your healthcare provider.
