Other symptom severity scores show no improvement with SSRIs
Five additional RCTs not included in the meta-analysis that used standardized symptom severity scores other than the CDRS-R (Schedule for Affective Disorders and Schizophrenia for School-Aged Children [K-SADS], Montgomery-Asberg Depression Rating Scale [MADR], and Hamilton Depression Rating Scale [HAM-D]) found no improvement with fluoxetine (2 RCTs; 63 patients, total), citalopram (one RCT, 233 patients), or paroxetine (2 RCTs; 466 patients, total).
Certain drugs cause significantly more adverse events than placebo
Ten RCTs evaluated adverse events in adolescents treated with fluoxetine, escitalopram, citalopram, and paroxetine and reported a small increase over placebo when all medications were combined as a group (RR=1.11; 95% CI, 1.05-1.17). Investigators reported that the individual antidepressants fluoxetine, escitalopram, venlafaxine, and mirtazapine produced significantly more adverse events than placebo (P values not given). No studies compared antidepressant medications against each other for either efficacy or potential harms.
RECOMMENDATIONS
A newly revised expert guideline recommends treating mildly depressed adolescents with a specific psychological therapy—individual cognitive behavioral therapy, interpersonal therapy, family therapy, or psychodynamic psychotherapy—for at least 3 months.2
For adolescents with moderate to severe depression, the guideline advocates psychotherapy with the option of adding fluoxetine, although using antidepressants in adolescents who haven’t at least tried psychotherapy is outside of the drug’s indications.
The guideline also recommends careful monitoring for adverse effects and close review of mental state—weekly for the first 4 weeks of treatment, for example. If fluoxetine doesn’t help, sertraline and citalopram are recommended as alternatives.
