WHAT TO DO FOLLOWING YOUR LEMTRADA INFUSIONS
Be sure to follow any post-infusion instructions from your healthcare team, which may include:
- Washing hands frequently to reduce risk of infections
- Staying hydrated
- Resting
- Eating regularly
Eat safely to avoid listeria
People who are about to begin or have recently started treatment with LEMTRADA can be more vulnerable to a serious infection caused by listeria, called listeriosis. Listeria infections have occurred as early as 3 days after treatment and up to 8 months after the last LEMTRADA dose.
Read these food safety tips to help you lower the risk of listeria infection.
Begin your monthly monitoring
Certain side effects of LEMTRADA can happen months and even years after treatment. That’s why it is important to begin monitoring after your first infusion and continue regular monitoring until 4 years after your last infusion. Monitoring can help your healthcare team find potential side effects early.

Monthly blood and
urine tests

Ongoing symptom
self-checks

Yearly skin exams
It’s very important to have your blood and urine tested even if you’re feeling well and do not have any symptoms from LEMTRADA and relapsing MS.
