Taking Ramipril In morning for several years. Recently started taking Laxido & banana (for breakfast). About the same time started coughing frequently but intermittently & became slightly breathless when walking. 2 days ago doctor called Emergency as I had persistent chest pain & burping. No heart attack but abnormal ecg, which however improved after being in A&E for several hours. Wondering if Ramipril + laxido + banana too much potassium?
