Tricyclic antidepressant overdoses in adolescent patients

Area of Science:

• Pharmacology
• Adolescent Psychiatry
• Toxicology

Background:

• Tricyclic antidepressants (TCAs) are prescribed for adolescent psychiatric conditions, but indications can be unclear.
• Increased use of TCAs in adolescents raises concerns about the frequency and severity of overdose ingestions.
• Accurate documentation of ingested TCA amounts is often lacking.

Purpose of the Study:

• To determine the medical seriousness of tricyclic antidepressant ingestions in hospitalized adolescents.
• To evaluate the utility of plasma TCA level measurements in assessing overdose severity.
• To inform medical management strategies for adolescent TCA overdoses.

Main Methods:

• Plasma tricyclic antidepressant levels were measured in nine hospitalized adolescent overdose patients.
• Clinical data regarding ingestion amounts and patient outcomes were collected.
• Medical seriousness was defined by plasma TCA concentration measurements.

Main Results:

• Two out of nine adolescent overdoses were classified as medically serious based on plasma TCA levels.
• Supportive care and cardiac monitoring were provided to all patients.
• A fatality occurred in one medically serious overdose case despite optimal management.

Conclusions:

• Plasma TCA level measurements are valuable for assessing the seriousness of adolescent overdoses.
• Even with optimal management, severe outcomes including fatalities can occur in adolescent TCA ingestions.
• Further research is needed to refine indications and safety profiles for TCAs in adolescents.
