Description
What is Tecfidera (dimethyl fumarate)?
Tecfidera (dimethyl fumarate) is an oral Nrf2 pathway activator and anti-inflammatory medicine used to treat adults with multiple sclerosis (MS), specifically relapsing-remitting MS (RRMS)[1,2].
How does Tecfidera (dimethyl fumarate) work?
Multiple sclerosis (MS) is a disease where the body’s immune system does not work properly and starts attacking the brain and spinal cord (parts of the central nervous system).
This causes inflammation and damages the protective sheath around the nerves. The active ingredient of Tecfidera (dimethyl fumarate) works to reduce the inflammation and is thought to help regulate the activity of the immune system[1,2].
