I have recently been on Atenolol and I think it doesn't suit me. It was for my high blood pressure, which has remained high while I have been taking them. The GP has now prescribed Doxazosin 1 mg. I have not taken one yet as I am very apprehensive. I am not good with any medication! Do you think the Atenolol may have interfered with my thyroid levels and kept my BP up. My heart rate did go down. Any thoughts would be gratefully received.
