Fluoxetine increases suicide ideation less than placebo during treatment of adults with minor depressive disorder.
(Journal Article;Multicenter Study)
OBJECTIVE: Some reports suggest an increase in suicide ideations and behaviors in patients treated with antidepressants. This is an analysis of the impact of fluoxetine on suicide ideations in outpatients with minor depressive disorder. METHODS: Research subjects were adult outpatients with minor depressive disorder (N = 162), who received fluoxetine or placebo in a prospective, 12-week, double-blind randomized trial. The research participants were evaluated weekly with standard rating scales that included four suicide-related items: item 3 of the Hamilton Rating Scale for Depression (HRSD), item 18 of Inventory of Depressive Symptomatology (IDS-C), and items 15 and 59 of the Hopkins Symptom Checklist (SCL-90). Clinically significant intensification of suicide ideation was defined as an increase of ≥2 points on any of these items. RESULTS: Overall 60/162 subjects (37%) had an increase of ≥1 point during treatment and 17/162 (10.5%) of ≥2 points on at least one suicide item, with 12/81 (14.8%) placebo and 5/81 (6.2%) fluoxetine-treated subjects having a ≥2 point gain. Of the study participants with baseline suicide ideation, 9/22 (40.9%) placebo and 3/24 (12.5%) fluoxetine treated had ≥2 point increase (p = 0.04). Survival analysis revealed that subjects on placebo were significantly more likely (p = 0.050) to experience a ≥2 point increase on one or more item, a difference that emerged early and continued throughout the 12-week trial. CONCLUSIONS: Compared to placebo, fluoxetine was not associated with a clinically significant increase in suicide ideation among adults with minor depressive disorder during 12 weeks of treatment.
