I am 86 yrs old, had a small stroke 9/2, am on Losartan, Crestor, iso sorb mono, levothyroxyn and oxybutnin. I can take chlorothiazide as needed. Ido not seem to retain water. Would be advisable to take chlorothiazide anyway, because of my recent stroke? My recovery has been very good, although I still have not fully regained control of my left arm - of course, I'm left handed! Thanks for your help.
