Hi Angie and welcome
I am sure Lara will check in later.
In the meantime, do ask us any specific questions you may have and we will all try to answer. We are a mixture of parents who have children with TS as well as some adults who also post here and who have TS themselves
The medication you mention is not one I am familiar with and hopefully it doesnt have the kinds of side effects that many of the prescription meds for TS can bring to some people.
It is sad when other kids are insensitive....honestly, we found that being proactive and telling teachers and classmates was the best apporach...as you do not yet have a definitive diagnosis, perhaps the best approach is just that it is like an allergy and that he cant help the movements or sounds and that the docs are running tests for most effective way to treat.
We found that once classmates understood, they were in general far more accepting.
Your doc is right to wait on diagnosing as there is no finite test for TS and it is rather by observation and notation of duration and frequency of tics etc
IMO, The most comprehensive website on TS and its associated disorders is the TS-Plus site at
www.tourettesyndrome.net
At Latitudes/ACN we focus on the more natural ways to treat TS etc
www.latitudes.org
I have also recently bumped up a thread I have here on what was helpful for my son and here is the link to that too

We are here for you and your family angie....do let your grandson's parents know that they too can join here to receive support and much info sharing
all the best
