It is very individual. The tics can decrease with time as he adjusts to the med. They can also go away when the med is stopped. They are made worse with anxiety and come and go through childhood. Second or third line meds may be helpful (non stimulant, but also not the best for ADHD). Guanfacine can also be added for the tics and it has the bonus of helping ADHD symptoms. Look for the long Tenex thread for information.

my son is showing signs of motor tics-moving his arms and legs in a wierd way- he is on metadate cd 20 mgs, (decreased from 30 mg because of the tics), my question is, are there any adhd meds that don't aggrevate these tics? Will they go away once the meds are discontinued?
