Product Information

What is Avonex?

Avonex falls under the class of cytokines in the interferon group, which are protein molecules that are responsible for cell signaling and help fight infection in the body. Avonex is mainly used in slowing the progress of multiple sclerosis, including in those patients that relapses. Avonex will not cure multiple sclerosis, as there is no known cure for this disease. Available only in injectable form, Avonex is manufactured by Biogen and was approved by the Food and Drug Administration (FDA) in May 1996.

Active ingredient

The active ingredient of Avonex is Interferon beta 1A. These protein molecules have anti-inflammatory properties, where they limit the number of inflammatory cells crossing the blood brain barrier. They also stimulate the secretion of the nerve growth factor. This nerve growth factor enhances nerve growth, protection, and maturation.

Conditions treated

  • Avonex is used in slowing the progression of multiple sclerosis in relapsing patients.

Generic vs brand name

Avonex is known by its generic name, interferon beta-1a. Other brand names of this medication include Rebif.

Dosage information

Use your medication as directed by your healthcare professional. Avonex can be taken with or without food and can only be administered intramuscularly.

  • Avonex is administered intramuscularly using a special injection called the Avonex pen. This is a single use filled glass syringe that contains 30mcg (micrograms) of Avonex. A recommended dosage of 30mcg of Avonex is injected intramuscularly once every week. The first dose can be started at 0.75mcg and can be increased each week until the recommended dose is attained. The titration of Avonex 0.75mcg can be measured by using 3 separate titration devices called the AVOSTARTGRIP kit.
