Methylphenidate (MPD) is commonly prescribed for patients with Attention Deficit/Hyperactivity Disorder (ADHD). Although used off-label, MPD forms part of complex and multifactorial treatment regimen for narcolepsy and hypersomnia, together with including behavioural interventions. The drug is sometimes also prescribed off-label to subjects with other mental illness or somatic condition to improve intellectual outcome, ease fatigue or enhance the ability to concentrate. Common side effects include headache, insomnia, decreased appetite and hypertension. Concurrently, clinicians should be aware of relatively rare but potentially threatening adverse effects including agitation and psychotic symptoms. Several case reports regarding MPD-induced psychosis have been published, but most of them regard children or teenagers (1) and much less is known about drug-induced psychosis in adults (2). In this article, we present a case report of MPD-induced psychosis in a 31-year-old, antipsychotic-naïve patient. Careful evaluation including clinical examination, medical and family history and possible early signs of psychosis is recommended each time before MPD treatment will be initiated.
