my pressure is 130-55, and i have been taking Eziday 25 mg for last 10 years or so.Recently i was requred to take iron injection, due low Homoglobin. but the hospital would not give me the shot unless my lower pressure was at least 60. I reduced mt Eziday intake to half a tablet. There is no increase in pressure, I am 78 years male. What should I do to increase my pressure to say 135- 140 and 65 or so?
