Key clinical point: Polypharmacy frequency can have a negative effect on relapsing-remitting multiple sclerosis (RRMS) patients.
Major finding: The proportion of polypharmacy among patients with a secondary illness to RRMS was four times higher than in patients without a secondary illness. Patients with polypharmacy were older, had a lower level of education, and had higher comorbidities than patients without polypharmacy.
Study details: Subgroups of 145 RRMS patients were analyzed. The subgroups were patients with polypharmacy, patients without polypharmacy, patients with secondary illness, and patients without secondary illness.
