I m having very bad dizzy spells. I took my blood pressure from when I was sitting, it was 128/72 and pulse was 72. When I stood up it dropped to 89/58, pulse was 90. I have been on Atenolol 25mg in the am and the same at bedtime. I had a cardiac ablation and my blood pressure was running around 140/90 so they put me on that and I have not had any problems. I was 40 then and am 53 now. I take a lot of meds, for seizures, pain management, high lipids, and some smaller issues. Last week I developed my annual Bladder infection and was in awful pain and felt like my head was in a cloud for about a week. Just stopped taking the ABT Macrodantin for that yesterday. Just wondering if you had any ideas what this could be? By the way I drink more fluids than a fish. My mouth is always dry from all the meds I take.
