I can’t tell you how many times or with how many different people I have had this SAME conversation. This time something changed.
I have been on Tysabri for almost 13 years. That is means close to 140 infusions. I don’t know the exact number, but I’m pretty sure Biogen (the company that makes the drug) could give you an exact number, as well as my JCV number, how many lesions I have on my brain and spinal cord, etc.
Facts we know:
- The longer you are on Tysabri, the more likely you are to develop a deadly brain virus called PML. Because of this, most doctors only prescribe Tysabri for a few years before recommending a different drug.
- While on Tysabri you have to have blood tests for the JC Virus every 6 months and an annual MRI to monitor your risks for developing PML.
Two years ago, not only did I test positive for the JC virus, but my numbers were quite high. (1 is bad, I was at 3.43.) My neurologist suggested that I consider changing to a different MS treatment. I refused. Tysabri has been a miracle drug for me. (Many posts about it) I did however agree to more frequent JCV testing and MRI’s. I am supposed to go every 4 months, but I haven’t because….well life.
Over the next 6 months, my JC numbers continued to climb to 4.69, so I made what I feel was another concession. Instead of getting an infusion of Tysabri, every 4 weeks, I would allow them to extend the time between doses to 6 weeks. (Personally, I hate the longer time in between infusions, because the last 3 weeks are “slump weeks” for me, but my numbers have stopped increasing.) They are still high, but haven’t gone up, so that’s a good thing.
This last year I’ve noticed that I am more fatigued. I have trouble finding the right words and expressing my thoughts, and my legs are heavier and painful each night. I have been shrugging it off, and attributing it to the longer intervals between Tysabri infusions, the fact that I am getting older, and the additional stresses in my life. (taking care of my parents, covid, and dealing with people in general) , but my last MRI shows that I have new lesions in locations that correspond to my symptoms.
The entire time I was taking Tysabri (at 4 week intervals), I had no disease progression or increase in lesions. (Apparently a six week dosing schedule does not prevent relapses for me) The medical community considers the risks of pml too high for me to go back to a 4 week schedule, so maybe it’s finally time to change?
I’m scared that I am going to start having frequent relapses. I don’t want to go down that road again.
Before Tysabri, I was in a wheelchair. I know it’s not the end of the world, but still. I was severely depressed and was being hospitalized for MS flares approximately every 3 months. Not the kind of life I wanted to live.
I am also pretty scared of some of the side effects of the other drug options available. 😦
I come to wordpress when I need to “get out of my head”. Thank you for allowing me to do that, and reading along. It helps to not feel so alone.
