Beta blockers are either NON-SELECTIVE or SELECTIVE.
The non-selecive blocks both beta-1 and beta-2 receptors...blocking beta-2 receptors in the lung causes bronchospasm in asthmatics.

But metoprolol (Toprol) is a SELECTIVE BB so the drug shouldn't be a problem for you. However, since blockade is relative rather than absolute, the asthma exacerbation may well STILL be from the drug.

Why not try another non-selective BB for a month or so, the most common is atenolol. Maybe it will treat you better.
Stay clear of propranolol or nadolol...both NON-selective and likely to cause you worse breathing problems.
