Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. Your concern, I would explain that it is not recommendable to take concomitantly valsartan and benazepril. So, it is OK to take benazepril/amlodipine twice daily instead of your currrent therapy. If your blood pressure values are above the normal ranges, you can add hydrochlorothiazide to your therapy. Hope I have answered your query. Let me know if I can assist you further.
