The Perindopril is an Ace, and the other one is a diurectic. I've never tried either of them, but give it a shot and see how it works. Most common side effect with the Ace is a naging cough, I had it with Altace, and the diurectic is suppose to rid your body of excess fluids.
Hope the combination works, good luck. I know what it is like to keep switching meds., as do alot of other folks here, and it is a pain, but guess we have to find the right combo. Right now I am on Avapro, which is an ARB, and Atenolol 25 mg. which is a Beta blocker, and most of the time it works pretty good. Hang in there, although it is a hassle to keep switching, U just might do fine..
I am very drug sensative, so it took quite a few changes to get me on something that didn't drive me BATS!!!! Good luck!!
