How Lemtrada Is Given

WHAT IS THE DOSING FOR LEMTRADA?

LEMTRADA is given through a needle placed in your vein (IV infusion).

ROUND 1

One infusion a day on 5 consecutive days

ROUND 2 (1 YEAR LATER)

One infusion a day on 3 consecutive days

2 rounds of treatment over 2 years with LEMTRADA for relapsing MS with additional courses, as needed.

ADDITIONAL ROUNDS IF NEEDED

You and your healthcare provider may decide that you need one or more additional rounds of treatment. If so, this would occur at least 1 year after your last round. Any additional rounds would consist of 3 treatment days in a row.

MONTHLY MONITORING

Monthly monitoring to detect potential side effects starts after your first infusion and continues until 4 years or longer after the last round of treatment.

WHAT HAPPENS DURING TREATMENT?

  • It will take approximately 4 hours to receive 1 dose of LEMTRADA. The time may vary depending on a number of factors
  • You will be monitored closely during the infusion and for at least 2 hours following the completion of the infusion to watch for any infusion reactions
  • You will be given certain medications prior to treatment
  • LEMTRADA can cause serious side effects during infusion or up to 24 hours or longer after you receive LEMTRADA. Tell your healthcare provider immediately if you experience any discomfort during or after your infusion. You may also be given other medicines before, during, or after the infusion to try to reduce your chances of getting these reactions or to treat them if they happen

WHAT HAPPENS AFTER TREATMENT?

  • 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 your healthcare provider find some side effects early
