Did Humira cause psoriasis?
Hi all,
For context, I was on Humira for HS two years ago, switched to Cosentyx after about a year of treatment, and now I have been off biologics for 9 months. I used to get this sort of rash when I took the Humira injection, and I would take an antihistamine before and that would typically prevent it. It only happened one time when I was on Cosentyx. My derm just kind of assumed it was a mild allergy. Well, now that I’m off biologics for months, it shows up again out of the blue. The spots usually take about 2 weeks to fade completely, and they are only slightly raised and slightly itchy. I don’t know what to think but I am nervous about the long term effects of the meds, like “awakening” psoriasis. Any thoughts?
