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


Your MS One to One® Nurse will call and tell you what time to arrive for your infusions. You should plan on being at the infusion center for the full day. It usually takes 7 to
8 hours to complete the whole infusion process, including observation period after the infusion.


  1. Arrive early in the morning to check in, meet the infusion staff, and get comfortable.
  2. Your infusion nurse will start an IV line in your vein.
  3. The LEMTRADA infusion takes about 4 hours. During this time, you can read, listen to music, watch TV, or take a nap.
  4. For 2 hours following your treatment, you’ll stay at the infusion center while the staff makes sure you’re doing fine and can go home for the night.
  5. You’ll be given corticosteroids on the first 3 days of each round of treatment. Your doctor may also suggest that you take common over-the-counter medications such as an antihistamine and a fever reducer.
  6. You’ll be given an antiviral before treatment and will continue until your immune cells reach certain levels.
