Our dd is 14. She was on Risperdol for a short period. It did help with her tics in a minor way, but the side effects certainly outweighed the benefits of this drug.
The medication made her extremely tired, no energy for doing any form of excersize, and made her feel more hungry. She gained weight from the medication and her self esteem just fell through the floor. We found her to be more adgetated on this medication. She's tried several of these medications (anti-psychotics) and really bad side-effects with all of them.
The other medication we tried was Clonidine. It was also somewhat effective with supressing tics, but it also made her extremely tired all the time and she gained so much weight that she hated herself for it. Even on the lowest dose, she was always tired, but it seemed to give her a huge appetite which didn't help.
She is now taking an anti-anxiety medication called Clonazepan.
It's been a amazing help with her tics!
Our Psychiatris who specializes in TS said this drug is found to have anti-tic qualities. she takes a fairly midl dose (.2x .25 mg) at bedtime and then (.25 mg) again in the morning.
Being different is special.
