Selective serotonin-reuptake inhibitors (SSRIs) appear to be the safest, given current data.
Major safety concerns—prompting a US Food and Drug administration (FDA) black box label warning—have been raised about increased risk of suicidality (ideation, behavior, and attempts) among adolescents receiving antidepressant therapy. Studies indicate that SSRIs and venlafaxine increase the absolute risk of suicidality by 1% to 2% compared with placebo. However, no suicides occurred during any study. On detailed subanalysis, each SSRI was as safe as placebo, and only venlafaxine demonstrated a statistically significant increase in risk of suicidality (strength of recommendation [SOR]: A, meta-analysis).
Information about the safety of tricyclic antidepressants in young people is limited because adverse effects have not been systematically reported in trials (SOR: A, meta-analysis).

Treat with vigilance
Jason Jason Crawford, MD, MPH
University of Nevada School of Medicine, Reno
Based on the available evidence, I’m confident in my decision to use SSRIs to treat depressed adolescents. But the FDA black box warning often leaves me with a sense of apprehension as I write the prescription. I consider this a healthy reminder that depression in adolescents is no small matter, and its treatment shouldn’t be taken lightly.
In my practice, patient and family education always accompany the use of SSRIs, as does weekly follow-up in the beginning. Of the many patient education resources available on the Internet, my favorite Web sites include:
- www.familydoctor.org,
- www.aacap.org (Facts for Families),
- www.kidshealth.org (features pages for both parents and teenagers), and
- www.medlineplus.gov (handouts in English and Spanish and interactive tutorials).
Finally, no adolescent leaves my office without suicide precautions and phone numbers of local and national suicide prevention hotlines (www.suicidehotlines.com).
Evidence summary
In 2003, the United Kingdom’s Expert Working Group of the Committee on Safety of Medicines (CSM) and the FDA conducted a review and meta-analysis, respectively, of the newer antidepressants used in children and adolescents.1,2 Based on these studies, the FDA mandated that all antidepressant labels carry a black box warning about the increased risk of suicidal thinking and behavior (suicidality) among adolescents taking the medications.
No suicides, but a two-fold increase in suicidality
A recent study that incorporated the FDA meta-analysis analyzed data from 4582 patients. Although no completed suicides were reported in any trial, the drug-treated groups had a two-fold in-crease in suicidality compared with placebo groups (4% vs 2%; number needed to harm [NNH]=50).3 A recent Cochrane review confirmed the increase in absolute risk (1.8; 95% confidence interval [CI], 1.19-2.72).4
Two subsequent analyses estimated the difference in risk to be 1.6-fold with a 95% CI of 1.0-2.7 (3% vs 2%; NNH=112).5,6 The lower estimated risk results largely from a statistical reframing rather than any major difference in data analyzed. The analyses used a random-effects model instead of a fixed-effects model to calculate suicidality, assuming heterogeneity in the drugs used, trial de-signs, and outcome measures.3,6 All of the analyzed trials excluded patients at high risk for suicide, defined uniquely in the exclusion criteria for each trial.
The TABLE summarizes the increased risk of suicidality for each drug. Notably, venlafaxine had the greatest—and only statistically significant—increased risk, mostly because of suicidal ideation (7 of 9 events in 182 treated patients vs none in 179 placebo patients).6 (For a de-tailed look at the risk of suicidal ideation, suicidal behavior, or suicide attempt, see TABLE W1, available online at www. jfponline.com.)
Data on tricyclics in adolescents are scarce
Evidence concerning the safety of tri-cyclic antidepressants in adolescents is limited because adverse effects have not been systematically reported. A 2002 Cochrane meta-analysis found a statistically significant increase in rates of vertigo, orthostatic hypotension, tremor, and dry mouth among children and adolescents taking tricyclic antidepressants compared with placebo. The drugs are modestly effective in treating depression in adolescents; concerns about side effects and safety, however, have limited their use.7
Recommendations
The FDA encourages patients taking antidepressants and their families to be alert for signs of impulsive behavior or suicidal tendencies and to have a safety plan. The FDA, American Academy of Child and Adolescent Psychiatry, and the Society for Adolescent Medicine endorse close follow-up with periodic objective assessment.8-10
The Society for Adolescent Medicine explicitly directs clinicians to consider the FDA black box warning in the con-text of the need to treat major depressive disorder in adolescents and endorses pharmacotherapy for appropriately selected patients.10 Similarly, the American College of Neuropsychopharmacology argues that the risk-to-benefit ratio favors drug treatment for moderate to severe adolescent depression.11
