Some studies have shown an increase in the risk of seizures while on stimulant medication. Most of these patients have either a personal or family history of a seizure disorder, however, it may rarely happen in patients without any history of seizures. The FDA recommends discontinuing stimulant medication if seizures occur.
Studies have also shown there is a temporary slowing of growth in children that are consistently on stimulant medications. Monitoring to make sure children’s height and weight are increasing at normal rates is recommended. Stimulant medication may need to be adjusted or temporarily stopped if a child is not growing within normal ranges.
