An FDA study of 50 independent clinical trials has found a link between ADHD medications and hallucinations in children. About 2 percent of the children tested suffered from hallucinations, most of which were thoughts of creepy crawlies on the body. It appears that children under 10 years of age were more susceptible to this than were the older children. The study has been published in the journal Pediatrics.
This is why every psychiatrist and parent should carefully monitor a child when starting a new medication that affects the brain. Hopefully your child will be in the lucky 98 percent like my daughter was. If your child suffers any negative side affects, then it's time to contact the doctor right away and try something else.
