Hallusinosis due to methylphenidate overdose in an eight-year-old child: a case report

885 135


Methylphenidate, which blocks the presynaptic norepinephrine and
dopamine transporters, is the most common used medication and
offered as first choice in the treatment guidelines of attention deficit
hyperactivity disorder (ADHD). One of its rarely seen adverse
effects is, hallucinations that can be formed idiosyncratically,
which can be correlated with increased dopaminergic functioning
in synaptic cleft. We will present an eight year old boy diagnosed
with ADHD-combined type, and oppositional defiant disorder
(ODD) with no previous medical and family history who has
impulsively taken extra dose of methylphenidate in the course of
usual drug treatment. The acute hallucinosis presentation which
has subsided the next day completely with the cessation of drug
treatment will be discussed.
