Which is a common side effect of albuterol?

Explanation:
When a fast-acting beta-agonist like albuterol works, it mainly relaxes bronchial smooth muscle by activating beta-2 receptors. But some systemic absorption can occur, and at higher doses the drug can stimulate beta-1 receptors in the heart as well. That extra stimulation speeds up the heart, leading to tachycardia and sometimes palpitations—this is a common side effect clinicians watch for during inhaled therapy. Other potential effects, like potassium shifting into cells causing mild hypokalemia, can happen but are less common. Hyperglycemia or rash aren’t typical primary side effects of albuterol, so tachycardia best fits what’s commonly seen with this medication.
