I am on a related drug, Humira, and I have had a lot of hair loss. The hair loss started about three months after I had been on Humira. My GI and dermatologist swear it isn't the drug, but I am still a little suspicious. I started taking biotin about four weeks ago. I did a little internet research, which can always be a little dangerous, and a few people swear by it. I think the hair loss is slowing down a little -- whether it is the biotin or not I don't know, but it might be worth looking into.
