Hi Roadaction,
Welcome to Neuro Talk. I have heard of people taking both Ty and LDN. Even Copaxone is okay. Just the Interferons iare a no-go.

It also depends how long you are on Ty. If you just started, it is better to see if Ty is helping you..then add LDN so you know which is working or not.

I am not a doctor so ask your Ty doctor at infusion time. Some Neuro's may not know for sure. The Touch program may have protocols you have to follow. When is doubt ask. Good luck to you.
