ICD-11

Disorders due to use of other specified psychoactive substances, including medications are characterised by the pattern and consequences of psychoactive substances that are not included among the major substance classes specifically identified. Examples include khat, antidepressants, medications with anticholinergic properties (e.g., benztropine), and some antihistamines.

Delirium induced by other specified psychoactive substance is characterised by an acute state of disturbed attention and awareness with specific features of delirium that develops during or soon after substance intoxication or withdrawal or during the use of a specified psychoactive substance. The amount and duration of use of the specified substance must be capable of producing delirium. The symptoms are not better explained by a primary mental disorder, by use of or withdrawal from a different substance, or by another health condition that is not classified under Mental, behavioural and neurodevelopmental disorders.
