Treatment for relapsing-remitting multiple sclerosis (RRMS) is initiated upon fulfillment of new McDonald 2010 criteria for RRMS. In addition, lumbar puncture is an essential diagnostic method. Interferon-β, dimethyl fumarate, glatiramer acetate and teriflunomide are the first-line immunomodulating drugs (IMD) for RRMS. If the disease is active according to clinical or MRI evaluation during the first-line IMD treatment, alemtuzumab, fingolimod or natalizumab may be considered as second-line therapies. IMD treatment is discontinued upon the transition of RRMS to secondary progressive phase. Rehabilitation should be considered at every phase of the disease.
