Report TIC treatments using Tenex in Tourette Syndrome and Tics Posted July 3, 2018 Has anyone used Tenex to treat Tourette? My sons TICS are so bad that his neurologist wants to put him on Tenex. I was told it’s the mildest with the least side effects. If anyone had any experience in terms of effectiveness and side effects, please let me know. I have taken him to a PANDAS:PANS neurologist and is waiting on test result. My son’s Suffering from so many motor and vocal tics I’m actually considering the drug, if it’s helpful.
