Key words: ADHD, methylphenidate, psychosis.

In view of the ongoing rise of ADHD prescriptions among adults in Iceland, it is important that doctors are aware that psychosis is a rare but at times a serious adverse reaction to such treatment. In 2022 5% of adults were prescribed medication to treat ADHD in Iceland. In this case report we present a case of methylphenidate-induced psychosis in a young man with no previous history of psychotic episodes who required admission to the psychiatric intensive care unit.
