Abstract

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.

Özet

Presinaptik norepinefrin ve dopamin taşıyıcılarını bloke eden metilfenidat, dikkat eksikliği hiperaktivite bozukluğu (DEHB) tedavisinde en sık kullanılan ve tedavi rehberlerinde birinci tercih olarak sunulan ilaçtır. Nadir karşılaşılan yan etkilerinden biri de, sinaptik aralıktaki artmış dopaminerjik işleyiş ile ilişkilendirilen, idiosenkratik oluşabilen varsanılardır. Polikliniğimizde DEHBbileşik tip ve karşıt olma karşı gelme bozukluğu (KOKGB) teşhisi konularak metilfenidat tedavisine başladığımız, özgeçmiş ve soygeçmişinde herhangi bir hastalık öyküsü bulunmayan sekiz yaşındaki erkek bir çocukta, olağan ilaç tedavisi sırasında impulsif bir şekilde aldığı fazladan bir doz kısa etkili metilfenidat ile gelişen ve ilacın kesilmesiyle birlikte ertesi gün tümüyle gerileyen halüsinoz tablosunu tartışacağız. Anahtar kelimeler: Metilfenidat,
