Dear Amy,
We believe that stimulant medications do not actually cause tics, but rather potentiate the appearance of tics in a child who is already vulnerable to them. It is very likely that the tic will disappear, since its onset can be directly associated with the start of the stimulant compund. However, there is no assurance that you will not see a continuation of tic behavior, whether due to Tourette's or some other tic disorder. Time will tell.
