Which of the following is a common adverse effect of SABA medications?

Tachycardia is a well-known common adverse effect of Short-Acting Beta Agonist (SABA) medications, which are frequently used to provide quick relief from acute asthma symptoms. SABA medications function by stimulating beta-2 adrenergic receptors in the lungs, leading to bronchodilation. However, this stimulation can also affect beta-1 adrenergic receptors in the heart, which can result in an increased heart rate, or tachycardia. This effect is particularly important for patients to be aware of, as it can be concerning for those with pre-existing heart conditions or anxiety about their heart rate during an asthma attack.

Other options, while they may be associated with different medications or conditions, are not typical side effects of SABAs. For instance, hypotension could theoretically occur in rare cases but is not a common adverse reaction of SABAs. Weight gain is more commonly linked with long-term medications, especially corticosteroids, rather than SABAs. Dry mouth is more often a side effect associated with anti-cholinergic medications rather than beta-agonists. Thus, understanding the specific side effects of medications like SABAs is vital for effective patient management in asthma care.
