Abstract Objectives Treatment of multiple sclerosis patients with glatiramer acetate has been demonstrated a beneficial effect on disease activity. The objective of this prospective naturalistic study was to evaluate the impact of glatiramer acetate on fatigue and work absenteeism. Methods 291 treatment-naive patients with relapsing remitting multiple sclerosis were included and treated with glatiramer acetate for twelve months. Relapse rates disability fatigue symptoms days of absence from work and adverse events were monitored. Fatigue was measured with the MFIS scale and with a visual analogue scale. Results Total MFIS scores decreased by from to p . Significant reductions were observed on all three subscales of the MFIS. Fatigue symptoms assessed using a visual analogue scale .
