question: I was trying bisiprolol for my benign pvc s . I was experiencing a feeling of tightness in my bronchial tubes. I was upset to stop the medication because it worked so well. My doctor is sending me for a respiratory function test next week to be certain that I don t have asthma even though I have not been wheezing. Would there be a chance that I couldtake something for the bronchial side effects and go back on the bisiprolol?
