As I get myself prepared to go back on the cade I have read alot about maybe developing antibodies ...how do you know ?
 
Are there specific symptoms I should look for ?
Or does it simply not work ?? In that case when do we find that out ??

Good Morning,

This is a guess and I hope someone else knows the answer but perhaps the lab could do blood work to see if you have developed antibodies to this medication?

Sorry I don't have a definitive answer for you.  Happy Easter.

If you've developed antibodies, from my experience, Remicade starts decreasing in the effectiveness. So, an infusion will not last as long. The final, worst, sign is to have a reaction during an infusion. Remicade never lasted the full 8 weeks for me, but by the end I needed it every 4 weeks or I'd flare again.

Yes, there is a blood test by Prometheus Labs that will test for antibodies. They are expensive and not always covered by insurance, so you might want to look into that part first just to be aware of what you're asking for.

I knew I developed antibodies because during my second infusion of Remicade, I had an allergic reaction (hives, throat closing up, turned bright red in the face and felt faint). I would also feel like my arms and legs were crazily heavy the 2 days after my infusions. I dealt with it by being premedicated before my infusions and having the drip set very slow. It took 5+ hours for my infusions.
Since I was off Remicade for so long (since December 2003) last year when I needed something more than the Imuran I was taking, my doctor wouldn't let me go back on it. He said I'd have more severe reactions. He put me on Humira instead and that's been great. :)

i believe you've developed antibodies when it stops working. i used to be able to go 6-9 months between infusions. when it took over a week for it work after an infusion and then a month later i couldnt wait for the next one, i knew i was in trouble...

You will know because it will not work. Having a reaction to Remicade is not developing antibodies to it. Back several yrs ago when I first started it I reacted on the 3rd infusion when they tried to increase the rate of the drip. It was stopped I was given IV Soluble Medrol & Benadryl. We waited a bit then resumed the Remicade at a slower rate and I had no further problems. From the on I was always given pre-meds & never had a problem. I did it for 3 1/2 yrs and we stopped because it quit being effective, my infusions were every 4 wks too. My gi said then I may have developed antibodies because it quit working. I just had a Remicade infusion last Friday for a fsitula, given pre-meds no problems at all. Ask your dr to order pre-meds. Susie
