I have been taking 20mg of leflunomide a day alongside 15mg of pred for the last 8 weeks. Over the last week or so I have been getting severe stomach pains, sometimes during the night but this morning it was when I woke up. The pain is quite severe and lasts for about an hour. I am concerned about taking more leflunomide as it is listed as one of the side effects stating you should contact your doctor. I wondered if I should stop taking it and make an appointment to see the doc? I haven't taken it today as the pain was really bad. Any advise gratefully recieved.
