Drug Information:
Rapaflo (silodosin) is an alpha-adrenergic (AL-fa ad-ren-ER-jik) blocker. Rapaflo helps relax the muscles in the prostate and bladder neck, making it easier to urinate. Rapaflo is used to improve urination in men with benign prostatic hyperplasia (enlarged prostate). You should not take Rapaflo if you have severe kidney or liver disease. Do not take silodosin together with similar medicines such as alfuzosin, doxazosin, prazosin, tamsulosin, or terazosin. Rapaflo may cause dizziness or fainting, especially when you first start taking it. 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. Learn more
