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


You will need monthly blood and urine tests, self-checks, and yearly skin checks. These help to monitor for possible side effects that can show up months, or even years, after your last infusion, including autoimmune side effects and some kinds of cancers, including skin cancer (melanoma). It is important to have your blood and urine tested, even if you are feeling well and do not have any symptoms from LEMTRADA or your MS. This may help you and your healthcare provider find potential side effects early.

You and your healthcare provider will continue to schedule appointments. Remember, your risk of infection is greater following treatment. However, there are things you can do to help prevent infections. Make sure to rest, wash your hands often, avoid people with colds, and talk to your healthcare provider about any foods you should avoid.
