Bronchodilators, including beta 2 -agonists, should be readily available or administered concomitantly [see Dosage and Administration (2) ].

• Beta-blockers: Use with caution.

However, under certain circumstances, there may be no acceptable alternatives to the use of beta-adrenergic blocking agents for these patients; cardioselective beta-blockers could be considered, although they should be administered with caution.

Beta-adrenergic Receptor Blocking Agents Beta-blockers not only block the pulmonary effect of beta-agonists, such as salmeterol, but may also produce severe bronchospasm in patients with asthma or COPD.

Therefore, patients with asthma or COPD should not normally be treated with beta-blockers.
