Sudden death and tricyclic antidepressants: clinical considerations for children

Area of Science:

• Pediatric Pharmacology
• Child Psychiatry
• Clinical Toxicology

Background:

• Recent reports detail sudden collapse and death in three prepubertal children during desipramine treatment.
• Limited clinical information hinders establishing a definitive cause-and-effect relationship.

Purpose of the Study:

• To review the available information on sudden deaths in children treated with desipramine.
• To discuss potential mechanisms and clinical considerations for antidepressant use in pediatric populations.

Main Methods:

• Review of reported cases and existing literature on desipramine and tricyclic antidepressant use in children.
• Analysis of potential adverse events and monitoring requirements.

Main Results:

• Insufficient data exists to confirm desipramine as the cause of sudden death in the reported pediatric cases.
• Potential mechanisms include cardiac events, blood pressure changes, seizures, or heat stroke.
• The incidence of this adverse effect cannot be determined due to unknown treatment numbers.

Conclusions:

• No clinical recommendations regarding desipramine use in children can be made based on current knowledge.
• Clinical considerations for using antidepressants in children warrant further discussion and investigation.
• The incidence of death from accidental overdose of antidepressants is significantly higher than reported sudden deaths during therapeutic use.
