Well, maybe not unreported, but not reported often enough.
Over the last ten years I have ben on 5 different RA drugs, now only on two. The side effects of all of them was that they made me better and/or helped me to get back control over my life and self manage. So thank you Pharma Companies for producing them. Thank you Consultants for prescribing them. And thank you NHS for funding them. I like these side effects a lot.
