Hi I am currently under concor 2.5mg medication for high palpitation, anxiety, heart rate and bp at 130/80 or occassional 140/90. But i am feeling shortness in breathing. Feel it heavy in chest and slight pain also there. I consulted a pumonologist doctor and he gave me pulmoclear( acebrophylline and acetylcysteine) + bilastine 20mg tablet. My question is can I take it with betablocker. I forgot if I mentioned about concor tablet or not. So confusing. Note: ecg, echo and holter was normal during june test. I have low vitamin d3 and b12 levels.
