How does this medication work? What will it do for me?


Glatiramer belongs to a group of medications known as immunomodulators. Immunomodulators modify the way our body’s defense system works. Glatiramer is used to treat the relapsing-remitting form of multiple sclerosis (MS). MS is a disease that affects the way the nerves in our body work. It is an autoimmune disease (the immune system attacks the body), and cannot be spread from person to person.


In MS, damage occurs to the myelin sheath, a protective layer that wraps around a nerve, like insulation around electrical wiring. Normally, this sheath allows electrical messages to be sent down the nerve quickly and efficiently. If this insulation is injured, electrical signals in the central nervous system will not be sent properly. For unknown reasons, in MS, the immune system sees the myelin as foreign and attacks it.


Glatiramer is thought to help treat multiple sclerosis by altering the immune system in such a way that its harmful effects on the myelin sheath are reduced. It does not cure MS, but it may increase the time between relapses of the disease.
