Is there any relation between breathlessness and beta blocker dosage?
I have atypical asthma that has never really bothered me but for the past year I have been taking a hefty 5mg of bisoprolol daily. In the last 4-5 months my breathlessness has increased (I no longer have the breath to sing, or to keep up in a fast-paced conversation). My cardiologist believes this to not be heart related so I'm wondering if the beta blocker is affecting my lungs and that this could be dose-dependent. If it is, I can suggest I lower the dose; if not, I may need to change beta blocker. Does anyone else suffer from this and know the answer?
Apologies if this has been covered elsewhere but I couldn't find it. As always, thanks in advance.
