LEMTRADA is a prescription medicine used to treat adults with relapsing forms of multiple sclerosis (MS). 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.

Do not receive LEMTRADA if you are infected with human immunodeficiency virus (HIV).

Monitoring

Monitoring is just as important as getting treatment

While LEMTRADA is given in 2 treatment courses over 2 years, regular monitoring is very important because some of the side effects of LEMTRADA can happen months and even years after treatment.

LEMTRADA patient discusses required monitoring
“ The monthly monitoring is
actually very empowering.

I am glad that they're watching out for me.

Serious side effects can include autoimmune diseases, which may cause death. These may include blood, thyroid, and kidney disorders (i.e., anti-glomerular basement membrane disease). Kidney disease can lead to kidney failure needing dialysis or transplant and can be life-threatening if untreated. LEMTRADA may also be associated with some kinds of cancers, including skin cancer (melanoma), thyroid cancer, and blood cancers (i.e., lymphoproliferative disorders and lymphoma).

Because of risks of autoimmunity, infusion reactions, and some kinds of cancers, LEMTRADA is only available through a restricted program called the LEMTRADA Risk Evaluation and Mitigation Strategy (REMS) Program.

During an appointment, your healthcare provider will tell you more about the program and how to enroll.

In addition to the REMS program, there are other steps taken to keep track of certain LEMTRADA side effects, like monitoring.

Monitoring may help your healthcare provider find side effects early and will increase your chances of getting better.

Monitoring includes:

Monitoring includes:

  • Monthly blood and urine lab tests
  • Ongoing symptom self‑checks
  • Yearly skin checks

It is important to have your urine and blood tested, even if you are feeling well and do not have any symptoms from LEMTRADA or MS.
