Because of its risks, LEMTRADA is generally used in people who have tried 2 or more MS medicines that have not worked well enough. It is not known if LEMTRADA is safe and effective for use in children under 17 years of age.

LEMTRADA TREATMENT PLAN Explore what treatment is like at every step—before, during, and after infusion.


After deciding on LEMTRADA, your healthcare provider will help you enroll in the LEMTRADA Risk Evaluation and Mitigation Strategy (REMS) Program. It makes you aware of potential risks and monitoring requirements, so you can make informed decisions about your care.

Here are two useful tools you can download to help you with your LEMTRADA treatment. The Conversation Guide can help you talk with friends, family, and coworkers about your treatment. The Patient Handbook is a step-by-step guide to preparing for and receiving LEMTRADA, along with your follow-up plan. You'll receive both as part of your Welcome Kit when you enroll in the REMS Program.


Once you review and sign the LEMTRADA Services Form with your healthcare provider, you’ll receive a call from an MS One to One Nurse welcoming you to the program. Your dedicated MS-certified MS One to One Nurse can help answer any questions about LEMTRADA treatment, as well as benefits and financial assistance. Your Nurse can also help you enroll in the Co-Pay Program, where you may be eligible to receive LEMTRADA at $0 out-of-pocket cost.*

*Patients who have coverage or prescriptions paid for in part or in full under Medicare, Medicaid, or other state or federally funded healthcare programs are not eligible. The LEMTRADA Co-Pay Program is subject to termination or modification at any time. If you are not eligible for the LEMTRADA Co-Pay Program and need help with out-of-pocket expenses, MS One to One can help review your coverage options. Depending on your specific situation, your MS One to One Nurse can direct you to other patient assistance programs that may offer you financial support. Treatment-related, infusion out-of-pocket costs are not reimbursable in MA, MI, MN, or RI.


  • Follow your healthcare provider's instructions to complete any pretreatment tests you may need. You may also be asked to get vaccinations at least 6 weeks before treatment.
  • You should avoid foods that are potential sources of Listeria.
  • You should use birth control while receiving LEMTRADA and for four months after your course of treatment.
