Does Dimethyl Fumarate Lower Your Immune System? 

Yes, Tecfidera (Dimethyl Fumarate) is known to modulate the immune system. It is an immunomodulatory medication used to treat certain autoimmune conditions, such as multiple sclerosis. While the exact mechanism of action is not fully understood, Dimethyl Fumarate is believed to have anti-inflammatory and immunomodulatory effects.

Dimethyl Fumarate is thought to work by activating a cellular pathway called the Nrf2 pathway, which has antioxidant properties. This activation is associated with a reduction in inflammation and a potential impact on certain immune system components. By modulating the immune response, Dimethyl Fumarate helps to manage autoimmune conditions like multiple sclerosis.

However, because of its immunomodulatory effects, Dimethyl Fumarate can also influence the body's ability to respond to infections.
