Amantadine, modafinil, and methylphenidate are three of the most commonly prescribed symptomatic treatments for fatigue for people with multiple sclerosis (MS), but robust evidence to support the use of these medications for this indication has been lacking. In this randomized, crossover, four-sequence, and double-blind clinical trial, researchers compared the efficacy of these three drugs to placebo. The intention-to-treat analysis was based on the improvement in the patient-reported outcome of fatigue (MFIS, modified fatigue impact scale scores). Amantadine, modafinil, and methylphenidate were not superior to placebo in improving multiple sclerosis fatigue and caused more frequent adverse events. There was a significant improvement in MFIS scores among participants on the placebo, suggesting a potential placebo effect. The results of this study do not support an indiscriminate use of amantadine, modafinil, or methylphenidate for the treatment of fatigue in multiple sclerosis.
