The VA uses tmed for things like treating disability cases that are not close to a VA center. Does that make any sense? I went through PTSD therapy at the VA and never found a therapy named tmed that was used on me. If you find out more let me know.
I assume you're asking what medication is best for PTSD? There are many, so see a psychiatrist to determine what will work best for you and he can also refer you to the proper therapist to help with this. I hope this helps and I wish you all the best.
