Hi Swon and welcome to Healing Wells chronic pain forum. I am sorry to hear of your situation and sure wish something out there would give you some relief, long lasting. I have crohns disease and I was on Remicade infusions every four weeks for 3 and a half years. I developed antibodies to it, developed Lupus plus it just lost its punch with me. I know of other on the crohns forum that has AS and they were on Remicade and it helped them pretty much. I would have thought by now something new would have been on the market for AS other than what you have been on.
I don't know if there would be a problem taking Celebrex and Remicade, why not ask a pharmacist this question. They know drugs better than anyone about the combination of the two. I do know about Celebrex being taken off the market but drs are allowed to rx it again they just monitor the patient more closely. I read everything I could get my eyes on about Remicade and never found any problems listed with anti-inflamms. Be careful taking Vicoden on an empty stomach, it can cause a lot of nausea if taken on an empty stomach.
I am sorry I am not of any help, but I would check with a pharmacists about the two meds you are speaking of to make sure. If you see the Remicade is not helping much you may want to consider being referred to a pain mgt dr. But, with pain mgt you are likely going to be on different medications, that just part of it. None of us wants to take medication but sometimes we have no choice.
Take care and let us know how you are doing.
