Several different types of medication may be prescribed to people who have multiple sclerosis (MS). One type, known as disease-modifying drugs, can prevent acute MS attacks, or relapses, and in some cases slow the progression of the disease, thereby preventing physical and cognitive disability. Disease-modifying drugs are sometimes called “immunomodulators,” because they affect the functioning of the immune system. Other drugs, primarily corticosteroids, are used to help control severe symptoms during relapses. There are also numerous drug treatments for managing ongoing symptoms associated with multiple sclerosis, such as pain, tremors, walking difficulty, and muscle spasticity.
