Selective may be OK: Selective beta 1 blockers are are tolerated by most asthmatics at lower doses. Non-selective beta blockers are contra-indicated in asthmatics because they block the beta2 receptors in the airways, leasing to broncho-constriction. Even non-selective applied to the eyes (for glaucoma) can cause asthma attacks or poorer control. High doses of beta1 may rarely cause similar worsening of asthma.
