Important Safety Information
The most common side effects with AVONEX are flu-like
symptoms (fever, chills, sweating, muscle aches, and tiredness)
early during the course of therapy. Usually, these symptoms
last for a day after the injection. Talk to your doctor if these
symptoms continue longer than the first few months of therapy,
or if they are difficult to manage.
