In the Database it says that to combine an Ace inhibitor with a beta blocker and Valsartan is dangerous. I am only taking 2 drugs so why does it call it 3 drugs? It said an Ace inhibitor and beta blocker with Valsartan. I'm only taking Valsartan(Diovan) with an Ace inhibitor... As far as I know I'm not on a beta blocker.
