Vumerity is a medicine used to treat adults with a type of multiple sclerosis (MS) known as relapsing-remitting MS. MS is a disease in which the immune system (the body’s natural defences) malfunctions and attacks parts of the central nervous system (the brain, spinal cord and the optic nerve of the eye), causing inflammation that damages the nerves and the insulation around them. In relapsing-remitting MS, the patient has flare-ups of symptoms (relapses) followed by periods of recovery (remissions).

Vumerity contains the active substance diroximel fumarate.
