Your right just because one didnt work doesn't nessecarily mean the other won't.
But your wrong about the cyclosporine. It doesn't take longer than 2 months. And your not even supposed to take it for longer than a few months. It is much more potent that Imuran and I was told by multiple doctors that if it wasn't working after 2 months then it definitely wasn't going to work.
And like I keep trying to say. Just because an immunosuppressant helps, does NOT mean that it is definitely an autoimmune disease. Those drugs also help inflammation.
