I've been taking Actemra, which is another form of tocilizumab, for almost a year. I take an injection every week for giant cell arteritis. I haven't had any side effects, and it has allowed me to taper prednisone from 60 mg per day down to 1. I was a little queasy at first about injecting myself, but I got used to it in a few weeks. It's pretty much foolproof with the auto-injector pens. I'm feeling better now than I have in several years. I expect to keep taking the injections for at least a couple more years.
