As promised, I looked in to another Rheumatoid Arthritis medication. This one is called Simponi (golimumab) and is what they call a TNF: a tumor necrosis factor blocker. TNF reduces the effects of anything which can cause an inflammation. It is self-injected under the skin once a month and is, often in combination with Methotrexate, given to treat RA, but it is also used for psoriatic arthritis,
