I have been on remicade for approximately a year and a half and I’ve been totally fine. I had my life back! Two weeks ago I went in for my eight week infusion and it didn’t do a thing! I’ve slowly been regressing and now I am in so much pain. I usually get some minor stomach cramps in my seventh week just before my next infusion, but they always go away right after I receive my next infusion.
My doctor put me back on Pentesa but so far it’s done nothing.
Is there any blood test that will show remicade anti-body resistance?
Is it possible the pharmacist messed up the dosage?
Have any of you had this happen to you?
What’s my next step?
"PROMETHEUS® Serum Infliximab/HACA Measurement can aid physicians in determining the dose of infliximab and guide infusion intervals. The HACA portion of the test detects Human Anti-Chimeric Antibodies (antibodies against infliximab). Patients that develop HACA may experience infusion reactions and/or a reduced duration of efficacy of infliximab. "
You need to make sure that your insurance will cover the cost of this test. Some insurance companies do not cover some of the tests done by Prometheus labs.
