high blood pressure
"I have taken it for about 4 or 5 years on and off.  I had stopped for awhile because my bp was fine but started this last year because I suddenly have elevated bp again and some swelling.  It works fine for me at 12.5.  I had a doctor prescribe 25mg and I had the leg cramps , some dizziness , dry eyes.  I realized that is because I am dehydrated.  If the medication is dehydrating you I would say you are prescribed too high of a dose.  Once it was decreased all those side effects went away and I do not swell and my BP is better.  If you ever complain to a doctor and they tell you just keep taking it and you don't feel good about it, follow your gut feeling."
