Hi,I may I answer your health queries right now ? Please type your query here...Hi, I've got a 15 year old daughter that suffers from juvenile Rheumatiod Arthritis since she was 6. We've been on a few biological medication, the latest is Mapthera, but she does not get better at all. She had a Mapthera infusion two days ago and suffer from vomiting and diaree.
