G'day toosaucey,
welcome to NeuroTalk.

I gather, from the medications you've listed, that your son has other conditions besides the tics? How's he doing with those? Unfortunately the age of 9/10 can be a time when tics are pretty full on for some little children. The good thing is that as time progresses it's very common for the actual tics with calm down a lot. I know of one adult who ended up having botox for extremely painful vocal tics. I'm not aware of this procedure being done very often and don't know of any children in my group of friends who've had that done. What sort of vocal tics does your son have? My children are grown now so we're not really dealing with the same issues now as we were when the children were little. Son is 20 and daughter is 18. It's good to meet you. Keep asking questions.
