I would talk to your surgeon before you go in . . . I was on Humira and they made me stop 2 weeks before and said that if I had still been on Remicade, they would have made me stop at least a month out. But, it may depend on the surgery itself. I had a full,
open 6 hour surgery. I am guessing that your gall bladder may be laparoscopically done. I would definitely check before you go in . . . better safe than sorry.
I sure hope you feel better soon and this surgery makes a world of difference!
