I developed a severe case of psoriasis shortly after starting Humira. It's now a year and 1/2 after I stopped the drug and I'm still dealing with psoriasis. I never had it before. It's a bit strange because Humira is a drug used to treat Psoriasis! Recently the FDA issued a warning of the danger of new onset psoriasis in pediatric patients on the antiTNF drugs . I'm well beyond "pediatric" age --but am happy to see some recognition of this particular side effect. Dealing with Psoriasis is sort of like IBD in that some drugs work for some people and they don't work for others. It's a matter of trial and error . Hopefully you can find something that works for you.
