The present invention relates to a method of treating MS in a human patient in need of such treatment and comprises administering to said patient a combination therapy in a single oral dosage form (e.g. a tablet or capsule) of dimethylfumarate and teriflunomide (or its prodrug leflunomide) which is more effective than the single agents alone and/or has reduced side effects and better tolerability than the single agents alone and/or can be given in a reduced frequency. Moreover, the present invention is directed to a pharmaceutical composition suitable for the oral treatment of multiple sclerosis consisting of dimethylfumarate and teriflunomide as active ingredients and one or more pharmaceutically acceptable excipients.
