I am 62 years female, with high blood pressure taking Avpro 300mg - 1 tablet, PMS-Atenlol 50mg 1/2 in the morning and 1/2 in the evening and Teva-Amiloride HCZ 5/50mg - 1 tablet in the morning. My systolic is 109 and diastolic is 56.  Should I be concerned. Teva-am was added last thursday. I have had a change in medication since May; either my potassium goes down or pressure keeps rising.
I read your question carefully, and I understand your concern. Looking at those values I would say that they are a little lower than normal. It is not something to worry about, for some people those values are common.However, since in your case you are under medication with some blood pressure lowering Chat Doctor.  So you should talk to your physician about the possibility of reducing your medication. I hope to have been of help.
