My cardiologist put me on metoprolol er succinate 50 mg. my primary care doctor doesn't think that i should be on it because of my asthma. any insight?

Beta Blockers: Your family doctor is right. The issue can be solved two ways. Have you noticed any change or worsening in your asthma symptoms? Do you feel you have a good relationship with your cardiologist? If so let him know that you have asthma ( he may have over looked this) and ask if you should change your medication like the primary doctor advises.

Asthma: Classically we didn't give beta blockers to patients with asthma. We have found however that many of these patients can tolerate beta blockers well. If there is a strong indication to use beta blockers, it is reasonable to try them in a patient unless the asthma is severe or known sensitive to beta blockers.

Risk benefit: By itself having asthma is not necessarily a contraindication to taking metoprolol. However, if one were wheezing and having bronchospasm, beta blocker would not be a good idea. We used to avoid bb in asthmatics but now we use them unless they have a problem.
