School-Day Medication Mistake: Who’s at Fault?
Who’s at fault for a school-day medication mistake? Here, what parents can do when the school misses or delays a child’s ADHD medication dosage during the day.

File a complaint with your state’s department of education, stating the fact that the ADHD medication was not given to your son at the right time. Follow up with a complaint to the federal Department of Education.
Request an IEP meeting — in writing — and have your son’s doctor spell out how and when your son should receive his medication. Formally request that the school have someone with medical training on staff.
Until the policy is changed, I would give your son his meds at home before school. It may be the only way to ensure that his doctor’s instructions are being followed.
