Which of the following is a common adverse effect associated with β-agonist use in asthma management?

Tremor is a common adverse effect associated with the use of β-agonists in asthma management. These medications work by stimulating beta receptors in the lungs, leading to bronchodilation and improved airflow. However, they can also affect beta receptors located in skeletal muscles, which may lead to side effects such as tremors. This is particularly notable with higher doses or more frequent use of the medication, as the systemic effects become more pronounced.

In contrast, drowsiness is not typically associated with β-agonists; instead, it is more often a side effect of other medications, such as antihistamines or sedatives. Dry cough is not a common direct effect of β-agonists either; it can sometimes be a symptom of asthma itself or related to other medications, like ACE inhibitors. Chest pain can occur but is less frequent and may be linked to other underlying conditions or improper use of the medication rather than being a direct adverse effect of β-agonists. Thus, tremor stands out as the most relevant and common side effect directly related to the use of these bronchodilators in asthma management.
