Cardura

Cardura


Generic Name: doxazosin (dox AY zo sin)


Brand names: Cardura, Cardura XL, Doxadura, Cascor, Carduran


What is Cardura?


Cardura (doxazosin) belongs to a group of drugs called alpha-adrenergic blockers. Cardura 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 may also be used for other purposes not listed in this medication guide.


Important information about Cardura


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.
