LABA should not be used for which condition?

Long-acting beta-agonists (LABAs) are bronchodilators designed for the management of asthma and chronic obstructive pulmonary disease (COPD). They are effective for long-term control of symptoms and are not intended for quick relief of acute asthma symptoms. LABAs have a delayed onset of action compared to short-acting beta-agonists (SABAs), which act rapidly to relieve acute bronchospasm.

Using LABAs for acute symptoms is not appropriate because their therapeutic effects take time to achieve, and patients experiencing an asthma attack require immediate relief. In these situations, SABAs are the preferred treatment due to their quick onset of action, enabling immediate dilation of the airways. Therefore, the answer identifies a critical clinical guideline: LABAs should not be utilized for acute symptom relief.
