How does it work?Although its exact mechanism of action is not known, Tecfidera is thought to inhibit immune cells and molecules, and may have anti-oxidant properties that could be protective against damage to the brain and spinal cord. The proposed mechanism is that it reduces cellular stress in the body. By reducing this stress, dimethyl fumarate may lessen the inflammatory response that occurs in MS.
