TIC treatments using Tenex in Tourette Syndrome and Tics Posted July 3, 2018 · Report reply 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.
