Thoughts on Tummy tuck surgery while taking Remicade for arthritis? Should it be skipped before/after surgery to help w healing?

I was on Otezla for a year. I stopped & started Remicade. I have only had one infusion last month. I am due tomorrow for my next dose. I canceled it until after surgery. I am scheduled for a tummy tuck October 20. I thought this would be best for the healing process? Not sure when to make my next remicade apt? The dr told me to ask the Plastic Surgeon about healing. I don't have my Pre Op until the 5th, which is 2 weeks before my surgery. Can I take remicade before/after a tummy tuck? healing?
