You or your child will also need to have your blood pressure and heart rate measured before starting this medicine and while you are using it. If you notice any change in your blood pressure, call your doctor right away. If you have questions about this, talk to your doctor.

This medicine may cause some people to feel a false sense of well-being or to become dizzy, lightheaded, or less alert than they are normally. It may also cause blurred vision or other vision problems. Do not drive or do anything else that could be dangerous until you or your child know how this medicine affects you.

Check with your doctor immediately if blurred vision, difficulty in reading, or any other change in vision occurs during or after treatment. Your doctor may want you or your child to have your eyes checked by an ophthalmologist (eye doctor).

Tell your doctor right away if you or your family notices any unusual changes in behavior, such as an increase in aggression, hostility, agitation, irritability, or suicidal thinking or behaviors. Also tell your doctor if you or your child have hallucinations or any unusual thoughts, especially if they are new or getting worse quickly.
