Which of the following describes adverse drug reactions associated with beta blockers used for migraine prophylaxis?

Beta blockers used for migraine prevention commonly cause a pattern of adverse effects tied to beta-adrenergic blockade. They slow the heart (bradycardia), reduce cardiac output (contributing to fatigue and hypotension), and can cause erectile dysfunction. If a nonselective beta blocker is used, it can block beta-2 receptors in the airways, potentially triggering bronchoconstriction and asthma symptoms. This combination of cardiovascular effects and possible bronchospasm in susceptible patients best describes the typical ADRs for these drugs, making that option the most accurate. Nausea, sleep disturbance, or weight gain may occur with various medications but are not as characteristic of beta blockers in this context.
