Why does Paxil cause some children, but not adults, to experience suicidal tendencies?
It is unclear why this is the case, but one possibility is because a child’s brain is still developing. Also, adult depression is very different from childhood depression. It has been difficult to find an antidepressant that works effectively in adults that also works well on children, and there have been a number of antidepressants that worked for adults but not for children. Children may also respond differently than adults to certain medications, and there have been side effects found to occur in children that did not show up in adults.
