What is AVONEX?

AVONEX is a prescription medicine used to treat relapsing forms of multiple sclerosis (MS), to include clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease, in adults.

It is not known if AVONEX is safe and effective in children.

How do I take AVONEX?

• AVONEX is given once a week by injection into the muscle (intramuscular injection)
• Inject AVONEX exactly as your healthcare provider tells you
• Your healthcare provider will tell you how much AVONEX to inject and how often to inject AVONEX. Do not inject more than your healthcare provider tells you to
• If you miss a dose, you should take your next dose as soon as you remember. You should continue your regular schedule the following week. Do not take AVONEX 2 days in a row
• Do not change your dose unless your healthcare provider tells you to
• Change (rotate) the injection site you choose with each injection. This will help decrease the chance that you will have an injection site reaction
• Do not inject into an area of the body where the skin is irritated, reddened, bruised, infected, or scarred in any way
• Always use a new, unopened AVONEX prefilled syringe, or single-use prefilled autoinjector pen for each intramuscular injection

During the start of your treatment, your doctor may recommend you build up to a full dose of AVONEX gradually over the first month. See Instructions for Use for complete dosing instructions.
