I've been taking Bystolic (a beta blocker) for 7 months now, without any negative side effects. Just recently I have started to have shortness of breath and other asthmatic symptoms. After lots of different tests, my doctor suspects it's my BP meds causing the symtoms and has decided to take me off the beta blocker and put me on a dieuretic to control my BP. I will start the new BP meds tomorrow-does anyone take a dieuretic type medication to control their blood pressure? Any side effects I should be aware of? I'm a 23 y/o female, 5'2, 110 pounds if that makes any difference to anyone with insight. Thanks!!
