I have been on this for 9 months as a prophylaxis against infection cause of still being stuck on pred. In that time I have not had any colds - always my big trigger. I believe from reading about it that it has an anti-inflammatory effect as well as being an antibiotic. I thought that Deek might like to put that under his wig for consideration as well as the methotrexates etc. Is anyone else on it too?
