I'm being treated by a dermatologist for a bad, itching rash that I developed after being on methotrexate and adalimumab (Humira) for a few years. The rash is getting better, but I'm afraid it will come back if I restart these two drugs as my rheumatologist wants. The itching from the rash is worse than the pain from the arthritis. What are my options?
Do you have a question about arthritis? Our medical experts answer reader questions on a wide range of topics.Submit Your Question
The key issue here is why you have the rash and whether it is indeed related to either Humira or methotrexate. Unfortunately, we cannot be sure without additional information. For example, we don’t know whether you have other medical conditions or take other medicines. Nor have we had an opportunity to examine the rash. What we can do is answer your question in general terms.
Humira and methotrexate represent a class of therapies called disease-modifying antirheumatic drugs (DMARDs). They are used in rheumatoid arthritis (RA) in order to slow the progression of disease and prevent permanent damage to joints and other tissues. Indeed, the 2008 recommendations of the American College of Rheumatology (the professional society of rheumatologists) emphasize the importance of DMARDs for treating RA.
The combination of methotrexate and Humira has been shown to be more effective for treating RA than either drug alone. Skin reactions with either medicine are quite uncommon. The most common skin reaction with Humira is at the site where an individual injects the medicine: pain, swelling, itching, and the like. The most common skin reaction with methotrexate is redness. Skin rash is uncommon when taking either medicine, particularly the kind of skin rash you describe, and particularly as the rash developed after you’d been on these drugs for a few years.
Your rheumatologist, who wants you to restart methotrexate and Humira, apparently suspects that the cause of your rash is something other than these drugs. One option might be to ask the rheumatologist about restarting them one at a time. If you don’t try methotrexate and Humira again, however, it is extremely important that you continue appropriate treatment with some kind of DMARD or DMARDs in collaboration with your dermatologist and rheumatologist.
