I have been on Leflunomide for 5 months with good results. Lasy month my pill changed from a white aspirin looking pill to a triangular peach colored pill with a harder coating. About a week after the change my symptoms started returning. At 10 days I was in serious pain. My doctor suggested I check with the pharmacy to see if they could special order the earlier pill (from Sandoz). About 7-10 days after changing back to the original pill all symptoms have disappeared again. Has anyone else had the pill change with any affect?
