question: I have high blood pressure and I am on 80 MG Doivan. In the last 3-4 months, my blood pressure has been creeping up. I have change insurance and doivan is 50 dollars a month. Do you think I could have Dr Robbe prescribe 320 MG a day and I could cut the pill in half. My insurance United Healthcare suggested I ask the doctor for the double dose and cut in half.I am 56 years old, ht: 5'7" 190 lbs. My family history has high pressure and high chorestol.
