What happened when stopped taking methotrexate?

If you take Methotrexate as part of your treatment for Arthritis you should consider your reasons for doing this carefully. I had to have an operation a short while ago and as a result was not allowed methotrexate prior to and shortly after the opperation as it isan immune suppressant something you don't need with bone surgery. In my case it was a simple case of just not taking it any more until a week after the operation
