Does anyone know the risks of frequently switching BP meds? Over the past 6 months, I've tried hydrochlorthiazide (didn't work), Norvasc (dizziness), Cozaar, Cardura, Avapro (all three, urinary frequency), and now I'm willing to try Diovan.

I've been told by one person that Diovan has the least side effects of all the BP drugs, so I want to make the switch; but, I'm wondering if all this switching is good. I am hoping Diovan will prove to be the one that I can stay on without side effects.
