Psychiatry · Child Psychiatry (ADHD, Autism, Intellectual Disability, Learning Disorders)

A 7-year-old boy has fidgetiness, inability to remain seated, running in inappropriate situations, blurting out answers, and difficulty waiting his turn, along with difficulty sustaining attention in class since age 4. These symptoms are present both at home and school. What is the recommended first-line pharmacotherapy for ADHD in this age group according to current guidelines?

  • A Atomoxetine
  • B Risperidone
  • C Clonidine
  • D Methylphenidate (stimulant)
Correct answer: D. Methylphenidate (stimulant)

Explanation

Methylphenidate (short-acting or modified-release) is the first-line pharmacotherapy for ADHD in children aged 6 years and above per NICE, AAP, and most international guidelines. It is a dopamine and norepinephrine reuptake inhibitor with robust efficacy in RCTs. Behavioural interventions (parent training, school-based) are recommended first in children under 6 years. Atomoxetine (non-stimulant SNRI) is second-line or preferred when stimulants are contraindicated (tic disorders, substance misuse risk, treatment failure). Clonidine and guanfacine are used adjunctively for tics or sleep disturbance in ADHD.
