Objective:
The objective was to report a case of experienced psychosis during the treatment with methylphenidate (MPH) in a cocaine-dependent adult treated for attention-deficit/hyperactivity disorder (ADHD) with comorbid cocaine dependence.
Conclusion:
ADHD is a frequent comorbidity in substance use disorder (SUD) patients. MPH may be effective in treating ADHD symptoms in SUD patients, thus preventing possible adverse outcomes. Cocaine-induced psychosis may be a risk factor for development of psychosis in the presence of a concurrent treatment with MPH.
