"My doctor switched me from Tamsulosin (Flomax) to Alfuzosin 10mg about 18 months ago.  Immediately after starting to take it and for the first full year, it worked without side effects.  Starting six months ago, I had small chest pains as well as a general weakness.  About one month ago, I almost passed out when I suddenly had a rapid heart event that lasted 20 minutes.  Since then, I felt like I haven't been getting oxygen properly, general weakness, and two more short racing heart events.  I stopped using Alfuzosin two days ago, and already feel better.  Never using it again."
