Hi all, my GI switched me from Stelara to Humira because after nearly 5.5 months on Stelara, I had zero improvement in symptoms. I took my loading dose of Humira on Weds and noticed a headache within an hour. That headache went away for a couple days, but today, I had a headache for the whole day. This is rare for me, as I don’t typically get headaches unless I don’t eat. But I ate just fine today. Has anyone else had headaches on Humira? Do they eventually go away after using Humira for a while? Also, how long did it take Humira to work for you?
