What the FDA labels say

In this setting, cardioselective beta-blockers could be considered, although they should be administered with caution.
Beta-Blockers Beta-adrenergic receptor blocking agents not only block the pulmonary effect of beta-agonists, such as terbutaline sulfate, but may produce severe bronchospasm in asthmatic patients.
Therefore, patients with asthma should not normally be treated with beta-blockers.
However, under certain circumstances, e.g., as prophylaxis after myocardial infarction, there may be no acceptable alternatives to the use of beta-adrenergic blocking agents in patients with asthma.
From the Labetalol (Labetalol Hydrochloride) label · effective 2025-12-19
Beta blockers antagonize the bronchodilator effect of beta-receptor agonists.
Bronchodilators Labetalol HCl antagonizes the bronchodilatory effect of beta-receptor agonist drugs; therefore, labetalol HCl is contraindicated in patients with bronchial asthma [see Contraindications (4) ] .
