Bruising While Injecting with Avonex
Bruising While Injecting with Avonex
I have been taking Avonex for over a year now. My boyfriend gives me my injections every Saturday night (usually in my upper thighs). He did the same this past weekend and the next morning I woke up with an enormous bruise at the injection site - this is the first time this ever happened. The injection did not hurt at all. Does anyone know what would cause this? Did I hit a vein or should I just make sure I apply pressure on the injection afterwards?
Re: Bruising While Injecting with Avonex
I occasionally get bruises, but these have only been small bruises about the size of a nickel to a quarter. In 4+ years of using Avonex, I've only hit a vein once. This was obvious when I pulled back on the syringe as there was no resistance and blood immediately entered the syringe. Do you always check to make sure that you haven't hit a vein? The large size of the bruise could very well be caused by this but you may wish to consult with your doctor.

My bruise is about the size of a silver dollar. I too have also had the smaller bruises. Regarding your comment about checking for a vein, according to Avonex's revised instructions, you no longer have to do that. I guess there is no problem if you should happen to hit a vein - except for what happened to me.

Hi Linda
I've also been on Avonex over a year.
I think I've probably hit a vein about 3 times, two small bruises and one really big one . I did experience worse side effects from the injection that ended with a large bruise.
It is also my understanding with the prefilled Avonex that you shouldn't draw back to see if you've hit a vein, you just take the plunge and hope for the best .
