My difficult child has ADHD and has a hard time sleeping. He is also very small for his age-50lbs. The psychiatrist just prescribed Remeron for him to help with sleep and to increase appetite (a common side effect). Remeron is an anti-depressant. difficult child is not depressed. I am aware that AD medications can be used for other uses but I worry about the "Black Box" warning regarding depression and suicide. Is it only a danger if the patient IS depressed or will it then cause depression and dark thoughts? There is a family history of depression.
