Contact Us

Your doctor is always your primary source of health information. You can also contact us with questions you may have. Whether you are currently on therapy or making the decision to start treatment, getting answers to some of your questions about relapsing multiple sclerosis (MS) can be as easy as picking up the phone and calling 1-800-456-2255.

Our highly knowledgeable Support Coordinators are here to help direct you to other MS resources specific to your needs.

Support Coordinators are available during extended hours from 8:30 AM to 8 PM ET, Monday through Friday, which means you can contact them from the privacy of your own home. The toll-free call and the services are confidential and completely free.
