I got a tattoo today (2hours in the chair), I have been on humira for a while. Follow cleaning and care instructions and you will be fine. It's just lots and lots of tiny holes in skin they need to be clean and able to heal, or infection will break out, humira will limit the body defense against it, thats when you are in trouble. Get a good tattoo artist, it will cleaner for less chance of infection, and you get what you pay for.
