I have been on Avonex for almost a year now and I noticed that my injection site has been bruising (about the last 4 shots) and I never had that before. Also I have "mystery" bruises all over my body - but I am not sure if that has anything to do with the medicine or not. I think I may just bruise easily. Never thought of a connection - but I am going to ask my neuro. Must be another side effect!!!
Are you talking about bruising at the injection site in the days following the injection? My wife got a huge bruise (a little larger than a half dollar) after an Avonex injection. We think that we hit a blood vessel because as soon as I pulled the needle out it bled a lot. That was four weeks ago and the bruised area is still visible. Her most recent shot resulted in a smaller bruise - maybe the size of a dime.
Where else do you inject? With the bruising my wife would like to inject is a less obvious place than her thigh.
Na, Im not talking about at the injection site. It just seems that I bump against something and I end up with these large, lumpy bruises that hurt like h---. I've never bruised easliy before either.
I too am on Avonex and have been since last October. I had Liver Function test done monthly for the first 6 months and then have them every 6 months.
I was told if I had any unusual bruising to notify my doctor. Apparently there is a small chance of Avonex affecting the Liver. Those precautions should of been explained when you decide to go on Avonex. I do bruise easily but I haven't got concerned.
