Studies have shown that children and teenagers with attention-
deficit hyperactivity disorder (ADHD; more difficulty focusing,
controlling actions, and remaining still or quiet than other
people who are the same age) who take atomoxetine are more
likely to think about killing themselves than children and
teenagers with ADHD who do not take atomoxetine. While your
child is taking atomoxetine, you should watch his or her
behavior very carefully, especially at the beginning of
treatment and any time his or her dose is increased or
decreased. Your child may develop serious symptoms very
suddenly, so it is important to pay attention to his or her
behavior every day. Ask other people who spend a lot of time
with your child, such as brothers, sisters, and teachers to tell
you if they notice changes in your child's behavior. Call your
child's doctor right away if your child experiences any of these
symptoms: acting more subdued or withdrawn than usual; feeling
helpless, hopeless, or worthless; new or worsening depress
