    Avonex for Multiple sclerosis

    I’m type 1 diabetic and seemingly react with the blood sugar on interferon side effects. So I switched from Rebif (3x per week) to Avonex (1x per week). The symptoms are now rarer but much stronger: Vicious leg cramps. Very severe flu symptoms (up to 4 days after injection, mitigate only with sufficient acetaminophen / ibuprofen (6-10 tablets per week).) Depression, pressure on the chest and shortness of breath, headache, fatigue.

    Avonex for Multiple sclerosis

    At first I had side effects in the form of flu-like symptoms. By now I can handle the Avonex quite well. I take a painkiller on Friday evening before the injection and then it’s good on Saturdays for me. Sometimes a bit tired or mild joint pain, but bearable.

    Side effects: Flu symptoms; Joint pain; Fatigue

    Avonex for Multiple sclerosis

    I have the experience that with me the side effects do not stop. The side effects here as if a big flu with strong fever logs on including body aches and chills are dependent on my on the day of the injection existing health condition. It goes so far that even 2 days later I’m not able to drive a car, because the attention and the overview are massively impaired. Even running is difficult for me then. Since it is positive but that massive restrictions do not occur after each syringe. It has even happened that was not up to a slight headache.

    Avonex for Multiple sclerosis

    I take ibuprofen 200 just before injecting and before sleeping, so I do not notice any of the flu-like side effects. If necessary, I take another ibuprofen the next morning. That Avonex only needs to be injected once a week is very good. In addition, there is no (hardly) skin irritation.
