Abstract

BACKGROUND: It is unclear whether the use of selective serotonin reuptake inhibitors (SSRIs) and other antidepressant drugs reduce the risk of suicide in people with depression. We explored the association between exposure to SSRIs and risk of suicide completion or attempt. METHODS: We conducted a systematic review of observational studies that reported completed or attempted suicide in depressed individuals who were exposed to SSRIs compared with those who were not exposed to antidepressants. We assessed the overall risk of completed or attempted suicide. RESULTS: Eight studies involving more than 200 000 patients with moderate or severe depression were included in the meta-analysis. Although exposure to SSRIs increased the risk of completed or attempted suicide among adolescents (odds ratio [OR] 1.92, 95% confidence interval [CI] 1.51-2.44), the risk was decreased among adults (OR 0.57, 95% CI 0.47-0.70). Among people aged 65 or more years, exposure to SSRIs had a protective effect (OR 0.46, 95% CI 0.27-0.79). Sensitivity analyses did not change these findings. In particular, for studies that used completed suicide as an outcome, exposure to SSRIs was associated with increased risk among adolescents (OR 5.81, 95% CI 1.57-21.51) and decreased risk among adults (OR 0.66, 95% CI 0.52-0.83) and older people (OR 0.53, 95% CI 0.26-1.06). INTERPRETATION: Based on data from observational studies, use of SSRIs may be associated with a reduced risk of suicide in adults with depression. Among adolescents, use of SSRIs may increase suicidality.

  • Barbui et al. (2009) found that the OR for the overall relationship between SSRI and suicidal behavior was 1.92 (95% CI, 1.51-2.44).

    “Barbui et al. (2009) found that the OR for the overall relationship between SSRI and suicidal behavior was 1.92 (95% CI, 1.51–2.44).”

    From Risk and Protective Factors of Self-harm and Suicidality in Adolescents: An Umbrella Review with Meta-Analysis (2024) · cites this paper as Barbui et al., 2009

    The Adolescents results report an OR of 1.92 (95% CI 1.51–2.44), but only for adolescents, not for an overall relationship across ages. The same passage reports ORs of 0.57 for adults and 0.46 for elderly people; the Interpretation likewise says the relationship varies by age. (LLM, conf=0.92)

  • The observational review by Barbui et al. (2009) suggested a promoting effect of SSRI exposure among adolescents but a protective effect in adults and the elderly.

    “The observational review (Barbui et al., 2009), including different age groups, suggested a promoting effect of SSRI exposure among adolescents but a protective effect in adults and the elderly.”
  • The increased risk of suicidal behavior may in fact be decreased in adults.

    “The increased risk of suicidal behavior reported in pediatric patients [99] does not appear to be seen in adults, and may in fact be decreased [99,100].”
  • The increased risk of suicidal behavior reported in pediatric patients does not appear to be seen in adults.

    “The increased risk of suicidal behavior reported in pediatric patients [99] does not appear to be seen in adults, and may in fact be decreased [99,100].”
  • Three of 120 associations (2.5%) had convincing evidence: SSRI use with increased suicide attempt or completion in children and adolescents, and any antidepressant before pregnancy or SSRIs during pregnancy with autism spectrum disorder.

    “Among the 120 associations, 3 (2.5%) were supported by convincing evidence, namely, the association between SSRI use and increased risk of suicide attempt or completion in children and adolescents 80 as well as the association between exposure to any antidepressant before pregnancy and SSRIs during pregnancy and autism spectrum disorder 51,52 (Table 2).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
