tuberculosis, latent
"I had to take Isoniazid 300 mg per day for positive skin test upon starting treatment with Humira for Psoriatic Arthritis. I had no side effects accept I seemed a little more edgy; I too was a little concerned at first about it being rough on your liver but they monitored it every two months, the results always came back fine (of course I did give up alcohol for the 9 month treatment) so my experience was not bad and I would say not to be overly concerned about liver failure because I put my liver through some real punishment in my younger party years and everything worked out. I am glad it's over, a 9 month treatment was long but you get used to it after a while."
