A client with MS experiences severe fatigue that interferes with activities of daily living (ADLs). Which medication might the provider prescribe?

Rationale: A. Baclofen is a centrally acting muscle relaxant used to treat spasticity in MS, not fatigue. While it reduces muscle stiffness, it can cause sedation and weakness, which may worsen fatigue rather than improve it. B. Tizanidine is also a muscle relaxant for spasticity management. Like baclofen, it can lead to drowsiness, hypotension, and generalized weakness, making it unsuitable for treating fatigue in MS. C. Amantadine is used specifically for MS-related fatigue. It has stimulant-like properties that help improve energy levels and enhance the ability to perform ADLs. It does not treat spasticity but directly addresses one of the most disabling symptoms of MS. D. Dantrolene is a peripherally acting muscle relaxant used for severe spasticity or muscle rigidity. It works by reducing calcium release in muscle fibers, but it does not treat fatigue and may also cause generalized weakness, which could worsen functional limitations in MS patients.
