very good question...You'll find a lot of studies on the sulfa antibotics and RA, some people do get relieve with them, as my sjogrens is so bad I could not breath taking the sulfa antibotics as they dried me out and I drank over 2 gallons of water and it still got me so dried out...You can google antibotics and RA treatments...
However, if your on methotrexate try and stay away from amoxicillin as mtx can increase in your body with amoxicillin antibotics...
Your RA doctor should have some knowledge on this as well....
