I have been on Coreg and Altace for 2+ years for CHF but had a descending aortic aneurysm repair in Sept of 2008 and was taken off all my meds for a period of time. I went back on them completely in Dec but in Jan, changed insurance carriers and pharmacies and I believe that I may have a problem with the generics of these meds that I am getting from this pharmacy. The Dr has been increasing the amount of both meds but my b/p is still staying much higher than it should. Has anyone had problems with the generic versions and/or manufactured by a specific company?
