Cardura is an oral tablet made up of an alpha-adrenergic blocker called doxazosin mesylate. You can purchase this medication as its brand name (Cardura) or as its active ingredient (generic alternative; doxazosin mesylate). You can purchase both of the two in 1mg, 2mg, and 4mg.

Cardura is used for the treatment for hypertension (high blood pressure) and can also be used to help improve urination in men with benign prostatic hyperplasia (which is when the prostate is enlarged).

This medication works by relaxing certain muscles, veins and arteries. It relaxes veins and arteries in though out the body to allow easier blood flow, reducing blood pressure. The muscles in the prostate and bladder neck become relaxed when doxazosin mesylate is used which allows for easier urination.

Your doctor will tell you before prescribing you Cardura exactly how to take this medication. Follow his or her directions; they can usually be found on the prescription label if you forget.

Take Cardura by mouth with or without food, usually done once a day.

Your dose is based on your response to treatment and the severity of your condition.

To avoid dizziness and/or fainting, take your first dose at bedtimes.

Take this medication regularly to get the most benefit out of it.
