I have had bisoprolol 1.25mg for 2 years and only after using it for 2 weeks i began to get a strange fluttering in my chest that after 2 months progressed to PVCs 2-3 times everyday, after 6 months I was diagnosed with heart problems a rythm problem that I NEVER HAD before being given this medication also side effects feeling unable to catch my breath, being strangled, having something stuck in my throat and horrible chest pain. Now 2 years later I have constant problems with my stomach, acid and bloating. Breathing is difficult like gasping for air or unable to breathe I feel I may pass out, dizzyness, headaches and now through this and how the hospital handled me that day in 2017 I have PTSS. Side effects from this medication are well known but they still prescribe them. I know how you feel and yes its terrifying. If I stop the medication and have something else I have less problems but here cardiologie returns me to Bisoprolol and everything begins again.
