What is Uroxatral?
Uroxatral (alfuzosin) is an alpha-adrenergic (AL-fa ad-ren-ER-jik) blocker.
Uroxatral helps relax the muscles in the prostate and bladder neck, making it easier to urinate.
Uroxatral is used to improve urination in men with benign prostatic hyperplasia (enlarged prostate).
Uroxatral may cause dizziness or fainting. 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.
You should not take alfuzosin if you have moderate to severe liver disease.
Uroxatral can affect your pupils during cataract surgery. Tell your eye surgeon ahead of time that you are using this medication. Do not stop using Uroxatral before surgery unless your surgeon tells you to.
There are many other drugs that can interact with alfuzosin. Tell your doctor about all medications you use.
