Well this week I got additional medicine changes. I was put back on coreg at 1.35 mg and metolazone at 5 mg. Both are diaretics (water pill) plus the coreg is a beta blocker. I was told to take the metolazone in the morning and the coreg in the evening. I have spent a lot of time in the bathroom...lol. My water retention is bad, my legs are so swollen they ache and feel tight. Then today I was told to increase my potassium pill by one more in the evening. Still doing the dobutamine IV treatments. I officially have a new (different) cardiologist....Dr. Lee the doctor that did my pacemaker/defibilator.
