Because medication only controls symptoms, once the medication is stopped, ADHD symptoms can return and affect the child’s ability to develop. Therefore, it is necessary to maintain medication for a long time, and parents need to learn to adopt appropriate supervision to help their children develop coping skills and methods and establish good behavioral habits so that they can maintain good status after medication is stopped. However, building behavioral habits and learning strategies and skills is not a short process. There is no hard and fast answer to the question of how long it takes to stay on medication, but it is certainly not too short. After compiling the opinions of authoritative experts at home and abroad, it is recommended that parents should insist on uninterrupted medication for 1-2 years if the child is effectively treated with medication and the side effects are not obvious. If the child’s symptoms resolve quickly on their own and the behavior is well established, they may be able to stop taking the medication successfully. If not, longer-term treatment may be needed.
