Hello, I ve been on Valsartan 160mg for 3 weeks, last week my blood pressure was elevated for 5 days 170s & 180s. my doctor s Pa increased the valsartan to 320mg two a day with 2 verapamil 180mg er. I feel horrible, dizzy and fatiqued, blur vision. I was on lisinipril for years and never felt this way. my doctor seems to think, that this is a better drug for me, and that I need to give it a chance for my body to get used to it. I feel sick on this drug and I don t know what to do. any suggestions?
