Hi Chelsea. I had minimal side effects from Humira, just some slight fatigue that lessened over time, and some bruising at the injection sites.
During the time that it was working for me, it was wonderful -- I never felt better. I have heard it described as similar to Remicade, but "cleaner."
I had a negative reaction to Remicade after only 3 infusions, but had over 6 months of healing with Humira before it stopped working for me.
Best of luck!
