There are so many BP medications out there and all of them have side effects. Some people are not bothered by the side effects and others cannot tolerate them at all. Everyone is different and reacts differently to these medications. It has been a trial and error thing with most of us. For myself, I have just learned to live with the side effects since I have found four medications that keep my blood pressure at a reasonable level. As far as what class of medications, I take four different classes. This combo seems to do the trick. There are many medications that are bashed on this board, but I have learned that it is an individual tolerance and what doesn't work for one person may work beautifully for another. I am sure you will find something that works for you. Good luck.
