Tysabri is a very effective medication and I have been lucky to be very stable on this for a good few years. I understand there are scary aspects to it, but the risks are very well understood and therefore can be assessed and managed.
are you aware of your JC virus status, as if you are negative, then you can be very relaxed as there is very low risk in that case.
I am still on the medication and have recently turned JC+, yet my risks are very low still (this is understood due to monitoring etc).
I will reconsider my choices once the risk profile changes but for now, don’t want to stop taking this amazing medication.
I wish you the best with the new phase of your journey.
