Monitoring is just as important as getting treatment
While LEMTRADA is given in 2 treatment courses, 12 months apart, regular monitoring is very important because some of the side effects of LEMTRADA can happen months and even years after treatment.
What patients are saying
Care Partners: You can talk to an MS One to One® Nurse about LEMTRADA and MS at any time.* Just call
Some of the serious side effects can include autoimmune diseases, which may cause death. These may include blood, thyroid, and kidney disorders (e.g., 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 (e.g., 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 from those side effects.
- 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.
