(Informational Notes) Avonex works best when used:

What is AVONEX?
Avonex Pen is used to inject Avonex.The active ingredient of Avonex is a protein calledinterferon beta-1a.Interferons are natural substances produced by the body toprotect against infections and diseases. The protein in Avonex is made exactly with the same ingredients as the interferon beta present in the human body.
What is AVONEX used for?
Avonex is used to treat multiple sclerosis (MS).Treatment with Avonex may helpto prevent it from getting worse, although it will not cure MS.
Each patient has specific MS symptoms.They may be:
MS also tends to worsen at certain times: this is known as a relapse.
Avonex may help reduce the number of relapses you may experience and slow down the disabling effects of MS.Your doctor will explain for how long you can useAvonex or when to interrupt treatment.
How does AVONEX work?
Multiple sclerosis is associated with neural damage (brain or spinal cord). In MS, the body's defense system reacts against its own myelin, that is, the insulation surrounding nerve fibers. When myelin is damaged, messages between the brain and other parts of the body are disrupted. This is what causes MS symptoms. Avonex seems to act by preventing the body's defense system from attacking the myelin.
(Notices) Avonex and Allergic Reactions Since Avonex is made with a protein, there is a small chance of an allergic reaction. Additional Information on Depression Do not use Avonex if you have severe depression or have thoughts of suicide.
