Hi I have a question, my father is experiencing hypertension, his blood pressure is measured to be the following for the past days: 160/80, 170/80, 160/100 - these are all taken via the manual sphygmo. however when we measure with a digital blood pressure monitor, it even raises up to 200/90 he's 66 years old, we're using OMRON SEM-1. he's taking micardis 80mg as maintenance but a doctor suggested he change to coversyl plus. he's diabetic as well. what could we do?
