Xatral XL 10 mg contains prolonged-release alfuzosin, a prescription alpha blocker that relieves urinary symptoms of benign prostate enlargement; it does not shrink the prostate. Take once daily after a meal as prescribed and swallow the tablet whole. It may cause dizziness or fainting from low blood pressure, especially when starting treatment; tell the eye surgeon before cataract surgery and seek urgent care for chest pain or a prolonged painful erection.
