Objective:
To test the hypothesis that selective serotonin reuptake inhibitor (SSRI) antidepressants may have a suicide emergent effect, particularly in children and adolescents.
Method:
Detections of different antidepressants in the forensic toxicological screening of 14 857 suicides were compared with those in 26,422 cases of deaths by accident or natural causes in Sweden 1992-2000.
Results:
There were 3411 detections of antidepressants in the suicides and 1538 in the controls. SSRIs had lower odds ratios than the other antidepressants. In the 52 suicides under 15 years, no SSRIs were detected. In 15-19-year age group, SSRIs had lower relative risk in suicides compared with non-SSRIs.
Conclusion:
The hypothesis that treatment of depressed individuals with SSRIs leads to an increased risk of suicide was not supported by this analysis of the total suicidal outcome of the nationwide use of SSRIs in Sweden over a period of 9 years, either in adults or in children or adolescents.
Insights
This study found no evidence that selective serotonin reuptake inhibitors (SSRIs) increase suicide risk in children or adolescents. Analysis of Swedish data over 9 years showed SSRIs were not associated with higher suicide rates in any age group.
Area of Science:
- Psychiatry
- Pharmacology
- Forensic Toxicology
Background:
- Concerns exist regarding a potential suicide-emergent effect of selective serotonin reuptake inhibitors (SSRIs).
- This effect is particularly scrutinized in pediatric and adolescent populations.
Purpose of the Study:
- To investigate the hypothesis that SSRI antidepressants may increase suicide risk.
- To analyze the association between SSRI use and suicide in different age groups, including children and adolescents.
Main Methods:
- A comparative analysis of forensic toxicological screening data from Sweden (1992-2000).
- Compared antidepressant detections in 14,857 suicides versus 26,422 control cases (accidental or natural deaths).
Main Results:
- Antidepressants were detected in 3411 suicides and 1538 controls.
- SSRIs showed lower odds ratios compared to other antidepressants.
- No SSRIs were detected in suicides under 15 years; lower relative risk in 15-19 year olds.
Conclusions:
- The hypothesis of SSRIs increasing suicide risk was not supported by this nationwide Swedish study.
- Analysis covered 9 years of SSRI use in adults, children, and adolescents.
- No increased suicide risk was observed with SSRI treatment across all age groups.
