Go through these in order and stop at the first one that applies. If you are reading this for someone else, answer for them.
Seek emergency help if the child has severe trouble breathing, collapses, has chest pain with severe illness, takes a possible medication overdose, or is at immediate risk of harming themselves or someone else.
Suicidal thoughts or behavior require urgent evaluation through local emergency services or a crisis service.
Contact the prescribing clinician promptly for concerning medication reactions, major mood or behavior changes, new hallucinations, fainting, or a racing or irregular heartbeat.
ADHD usually requires ongoing follow-up rather than a one-time visit.
Early in treatment, appointments may be more frequent while the plan is adjusted.
Once symptoms and side effects are stable, routine reviews still help track progress.
Follow-up may include feedback from the child, family, and school.
The clinician may review learning, friendships, family routines, sleep, appetite, growth, blood pressure, and emotional health.
Treatment should be reconsidered when demands change, such as during a school transition or adolescence.
Arrange a routine appointment if symptoms are worsening, treatment does not seem to help, side effects are persistent, or school performance or relationships are declining.
