Given the current situation, we understand that people may experience worry and even fear about how their disease and treatment may impact their personal risk. Sanofi Genzyme is committed to patient safety and to transparent communication. We are taking COVID-19 seriously, and we are committed to updating the communities we serve with relevant information related to our medicines to help inform health decisions.

As COVID-19 has emerged only recently, there are no available data regarding the impact of the virus on our current therapies. At this time, if you have general questions about our therapies, you should consult the current U.S Prescribing Information (USPI).

Each patient’s situation is unique, and patients and their healthcare providers are in the best position to make decisions regarding their care. In addition to local public health authority guidance, and local guidance from medical or patient associations, more information about COVID-19 can be found on the Centers for Disease Control’s (CDC) website or the World Health Organization’s (WHO) website.


LEMTRADA is a prescription medicine used to treat relapsing forms of multiple sclerosis (MS), to include relapsing-remitting disease and active secondary progressive disease, in adults. Since treatment with LEMTRADA can increase your risk of getting certain conditions and diseases, LEMTRADA is generally prescribed for people who have tried 2 or more MS medicines that have not worked well enough. LEMTRADA is not recommended for use in patients with clinically isolated syndrome (CIS). It is not known if LEMTRADA is safe and effective for use in children under 17 years of age.
