Most people experience flu-like symptoms when first beginning treatment with AVONEX. Usually, these symptoms last for a day after the injection. For many, these symptoms lessen or go away over time as their bodies adjust to AVONEX.
During the start of your treatment, your healthcare provider may recommend you build up to a full dose of AVONEX gradually over the first month. This is a process called titration.
The recommended dose of AVONEX is 30 micrograms (30 mcg) once a week. To reduce the incidence and severity of flu-like symptoms that may occur at this dosing level, you may start taking AVONEX at a dose of 7.5 mcg. You may subsequently increase the dose by 7.5 mcg each week for the next three weeks until you reach the recommended dose of 30 mcg.
The AVOSTARTGRIP® Titration Kit, which is used with AVONEX prefilled syringes, can help you get started with titration. Once you have achieved the 30 mcg per week recommended dose you may also transition to the single-dose AVONEX PEN: a prefilled, single-dose autoinjector with a needle that is half the length of the AVONEX prefilled syringe.
