I Am Taking Valsartan/HCTZ And Tekturna And Have Done So

I am taking Valsartan/HCTZ and Tekturna and have done so for past 4 years along with Bystolic for difficult to control HTN. My PCP's office called and stated the pharmacy notified them of drug interaction and to stop the Valsartan/HCTZ. I know if I do this, my BP will increase. I am not a Diabetic and have had no kidney issues in the past . What is the long term risk of taking these medications together? I have every 6 month lab which includes BMP for K+ and Cr. checks.
