Hello,
My Rheumy is switching me from Enbrel to Humira. I take my first does tonight. I'm not really worried about it, but like a lot of you on this site, I'm worried about weight gain. I didn't gain any weight with Enbrel, but I've read that some gained weight on Humira. I am only 5'2 and can't afford to gain any weight. I struggle to maintain where I am at and that's really too much as it is. 
I would also like advice from anyone who has went off biologics completely and what kind of success you had with it. All of my tests (blood work) are negative for RA, but my MRI's and Xrays say "possibly RA" and some are inconclusive. My hand surgeon has said it's RA, beyond a doubt, so based on that, my Rheumy started me on Enbrel, Methotrexate and Plaquenil. (don't take metho anymore due to problems).
So, the entire time I've been on Enbrel, about 6 months, I really didn't notice a change. At one point, I ran out of my Plaquenil for about a week and was in noticeable pain. My Rheumy said that if I was in that much pain missing one week of Plaquenil, then the Enbrel wasn't doing it's job, so that's why she's switching to Humira. So, this leads to the next question....I wonder if I really have RA. The Enbrel and Humira wouldn't effect the OA, would it? I just don't want to be taking medicine that I don't need to take.
Anyone have any info on this?
Thanks so much for listening.

Thanks for the post and good luck to you too!

You could always get a second opinion. I have heard that RA test show up negative even though the person does have RA its called sero-negative RA. There are different types of arthritis than RAand OA. You could have psoriatic arthritis and not have psorisis, and bios do work for that.
As for weight gain, I did not gain weight on humira and was on it for a year and half. So it probably depends on the person.
Thank you Hope.
