Hi i stopped taking methotrexate a year ago as i had side effects ie, really bad headaches, blurred vision and rainbows of lights. So am now on leflunomide 20mg daily + sulphazalasine tablets, but now im having major flare ups in 2 or 3 areas a time !! Also had injection every 2 months. The hospital say it can take 6 months for leflunomide to start working. Does anyone take this ? as im trying to get medication changed again as the pain is so bad i cant walk or use my hands at times ! This as started to affect my job which i really cant afford to loose.
