I have heart failure and was put on Ramipril initially. This was reasonable at first although i never felt completely right. the dose was increased and i began feeling more unwell. This in terms of feeling more fatigued and fuzzy headed. I reported this to the cardiologist nurse and in due course was changed to Candesartan 32 mgs. This made me feel simular to the lower dose of Ramipril but again still not feeling completely right. again i reported this and the Candesartan was reduced to 24 mgs. Again since this reduction i again have felt fatigued and fuzzy headed. Can anyone relate to this and possibly give some much appreciated advice.
