I presume that you take your blood pressure for a number of days and then inform your Doctor who then can either prescribe the medication or not? If not do you have to take your blood pressure every time you take the medication? What is the medication? 138/89 is on the highish side. Just a few tips we were given when taking my elderly Mother's blood pressure. The patient should sit down and relax for a few minutes before taking blood pressure. Do not take blood pressure immediately after exercise - unless told to do so, or after a meal or drinking. Then take 3 readings and choose the best of those. I also find when taking my own I need to relax after putting the cuff on before turning the machine on as it always seems to be a tangle and quite a bit of exertion to get it on correctly.
