I went to the doctor yesterday. I have been on Copaxone for about 3 years and two years before that on Avonex. My MRI had some changes in brain and thoratic lesion. Dr. did not receive entire report while I was there. She advised maybe taking me off Copaxone because of no exasperation on med. She also wants a cognitive study done. Then said something about progressive MS. My past diagnosis was RRMS.
I am not exactly sure what question(s) you are asking without more information. Are you asking if and when you should consider stopping a medication? If this is your question, the answer is complex and depends on the your individual circumstances. I would recommend discussing this further with your MS specialist.
