Interesting that you are taking acetaminophen rather than ibuprofen. The doctor knows best, however, its good to be aware that it is very easy to overdose on acetaminophen because its hidden in so many over the counter drugs and often physicians recommend not using acetaminophen because it contributes to liver toxicity, whereas cyclosporin does not damage the liver but contributes to kidney toxicity and high blood pressure. I am still learning about Remicade, I thought it was broken down in the liver, and according to the Remicade medication guide, there is a potential for liver toxicity.
My caution as is with everyone taking acetaminophen, look carefully at all the ingredients in various over the counter medications, its quite staggering where it lurks!! I became aware of this recently when my rheumatologist told me about a patient of hers, they could not figure out why her liver panels were falling, and finally had the patient bring in everything in her medicine cabinet and only then discovered the patient was inadvertently overdosing on Tylenol between alka-seltzer plus, Vicks Day Quil, benedryl allergy, midol, etc. The FDA site about discussion of acetaminophen:
