A look at some of the potential side effects
When considering LEMTRADA as your relapsing MS medicine, it's important to discuss potential common and serious side effects with your healthcare provider.
SELECTED IMPORTANT SAFETY INFORMATION
LEMTRADA can cause serious side effects including autoimmune problems, infusion reactions, stroke, tears in your arteries that supply blood to your brain (carotid and vertebral arteries), some kinds of cancers, thyroid problems, low blood counts (cytopenias), inflammation of the liver, serious infections, progressive multifocal leukoencephalopathy (PML), inflammation of the gallbladder without gallstones (acalculous cholecystitis), and swelling of lung tissue (pneumonitis). Because of the risks of autoimmune problems, infusion reactions and some kinds of cancers, LEMTRADA is only available through a restricted program called the Risk Evaluation and Mitigation Strategy (REMS) Program.
SERIOUS AUTOIMMUNE PROBLEMS
Some people receiving LEMTRADA develop a condition where the immune cells in your body attack other cells or organs in the body (autoimmunity), which can be serious and may cause death. Serious autoimmune problems may include blood, thyroid and kidney disorders, such as immune thrombocytopenic purpura (ITP), and anti-glomerular basement membrane disease.
STROKE AND TEARS IN YOUR ARTERIES THAT SUPPLY BLOOD TO YOUR BRAIN
Some people have had serious and sometimes deadly strokes and tears in their carotid or vertebral arteries within 3 days of receiving LEMTRADA. Get help right away if you have any of the following symptoms that may be signs of a stroke or tears in your carotid or vertebral arteries:
- drooping of parts of your face
- weakness on one side
- sudden severe headache
- difficulty with speech
- neck pain
LEMTRADA may also be associated with some kinds of cancers, including skin cancer (melanoma), thyroid cancer, and blood cancers (e.g., lymphoproliferative disorders and lymphoma).
Because of risks of autoimmunity, infusion reactions, and some kinds of cancers, LEMTRADA is only available through a restricted program called the LEMTRADA Risk Evaluation and Mitigation Strategy (REMS) Program.
