2Avonex Usages
In most cases, people with multiple sclerosis experience a relapsing form of the condition. It means that they have periods when symptoms worsen or recur. Avonex can be prescribed to treat the following relapsing forms of multiple sclerosis:
– Relapsing-remitting multiple sclerosis: This form is characterized by periods of remission where symptoms disappear or improve, followed by periods when symptoms worsen.
– Active secondary progressive multiple sclerosis: In this type, symptoms worsen all the time, but you may still have periods when symptoms only worsen for a short time.
Another use of Avonex is to treat clinically isolated syndrome, which is characterized by one period of multiple sclerosis symptoms that persists at least 1 day. The condition would lead to multiple sclerosis. [2]
