Hello,
Our 5-year old son was prescribed Risperidone to help with his impulsive aggression. We tried the medication for 3 months
and observed no change in is behavior
and so we slowly discontinued. About a month later, he developed what could be called a tic, but it expresses itself as if he can't catch a breath. He does this repeatedly, but has periods with no signs. Since then we found out that Risperidone is know for side effects such as tardive dyskinesia.
