Initiating dantrolene sodium therapy most commonly produces which systemic effect?

Explanation:
Generalized muscle weakness is the expected effect when starting dantrolene. This drug directly targets skeletal muscle by inhibiting calcium release from the sarcoplasmic reticulum, which dampens excitation-contraction coupling. With calcium less available for contraction, muscles don’t generate as much force, leading to widespread weakness and fatigue early in therapy. Nausea, dizziness, and headache can occur, but the most prominent immediate impact of dantrolene’s action is reduced muscle strength, so anticipate impaired performance with activities requiring effort and ensure safe practice during transfers and ambulation.
