ICD-10: T43.022

ICD-10 code T43.022 refers to "Poisoning by tetracyclic antidepressants, intentional self-harm." This classification is part of the broader category of poisoning and adverse effects related to drugs, specifically focusing on cases where individuals intentionally harm themselves using tetracyclic antidepressants.

Clinical Description

Definition

Tetracyclic antidepressants are a class of medications used primarily to treat depression and anxiety disorders. They work by altering the balance of neurotransmitters in the brain, particularly norepinephrine and serotonin. Common examples include amoxapine, maprotiline, and nortriptyline. When ingested in excessive amounts, these medications can lead to poisoning, which may result in severe health complications or even death.

Intentional Self-Harm

The term "intentional self-harm" indicates that the poisoning was not accidental but rather a deliberate act by the individual. This behavior is often associated with underlying mental health issues, such as depression, anxiety, or other psychiatric disorders. It is crucial to approach cases of intentional self-harm with sensitivity and a comprehensive understanding of the patient's mental health status.
