I am concerned about taking Bumetanide, I do need a diuretic and this was prescribed about 5 months ago, I was taking spironolactone twice a day and that was fine, however, the doctor said my potassium level was too high so he changed my prescription to Bumetanide and since I have been taking, I notice swelling in my ankles and hands and arms. I did mention to the doctor but he did not change my prescription. My blood pressure has gone up today the highest reading so far was 177/108 pulse rate of 81 which has me concerned. I do have a pacemaker and just had a new one implanted Dec. 17th, 2017, they have it set at 80, could this affect my blood pressure? Any help would be appreciated. Should I call my doctor? Thank you.
