Are the prefilled syringes of AVONEX equally effective as the powdered form of AVONEX in treating my MS?
Yes, prefilled syringes of AVONEX provide concentrated once-a-week dosing, delivering the same amount of clinically proven medication in less volume of liquid. Prefilled syringes of AVONEX contain 30 mcg of Interferon beta-1a in 0.5 mL of liquid volume. The reconstituted powdered form of AVONEX contains 30 mcg of Interferon beta-1a in 1.0 mL of liquid volume. AVONEX is the only MS therapy proven to be effective in people who have experienced a first attack and have MRI features consistent with MS. In a 3-year study, AVONEX reduced the risk of a second attack by 44%.
