What is Cardura?
Cardura (doxazosin) is an alpha-adrenergic (AL-fa ad-ren-ER-jik) blockers. Doxazosin relaxes your veins and arteries so that blood can more easily pass through them. It also relaxes the muscles in the prostate and bladder neck, making it easier to urinate.
Cardura is used to treat hypertension (high blood pressure), or to improve urination in men with benign prostatic hyperplasia (enlarged prostate).
Cardura XL, the extended-release form of this medicine, is used to treat benign prostatic hyperplasia and should not be used to treat hypertension.
You should not use Cardura if you are allergic to doxazosin or similar medicines such as alfuzosin (Uroxatral), prazosin (Minipress), silodosin (Rapaflo), tamsulosin (Flomax), or terazosin (Hytrin). Cardura may cause dizziness or fainting, especially when you first start taking it or when you start taking it again. Be careful if you drive or do anything that requires you to be alert. Avoid standing for long periods of time or becoming overheated during exercise and in hot weather. Avoid getting up too fast from a sitting or lying position, or you may feel dizzy.
Cardura can affect your pupils during cataract surgery. Tell your eye surgeon ahead of time that you are using Cardura. Do not stop using this medicine before surgery unless your surgeon tells you to.
If you stop taking Cardura for any reason, call your doctor before you start taking it again. You may need a dose adjustment.
Tell your doctor about all other medications you use, especially other blood pressure medications including diuretics (water pills).
