After a 2003 report linking selective serotonin reuptake inhibitors, or SSRIs, with increased suicide rates among children and teen agers was published, the use of this class of antidepressants in these age groups has decreased dramatically. This led to a change in labeling in 2003 that warned that use of the medications could increase suicidal thoughts and behavior among youths. Sadly, this ‘black box’ warning has caused a decrease in prescriptions for SSRI antidepressants which appears to have has triggered a sharp increase in suicide rates for these age groups, according to two papers that have recently been published.
According to a new study published recently in the American Journal of Psychiatry, SSRI prescriptions for children and teens decreased by 22% in both the United States and the Netherlands after government ‘black box’ warnings were issued.
As a result, in the United States, the youth suicide rates increased by 14% between 2003 and 2004, reports biostatistician Robert D. Gibbons and his colleagues at the University of Illinois at Chicago. This is the largest year-to-year change in suicide rates in this population since the Centers for Disease Control and Prevention began systematically collecting suicide data in 1979.
Additionally, between 2003 and 2005, Dutch youths experienced a 49% increase in their suicide rate and further, this increase shows a significant inverse association with SSRI prescriptions. Using these data, the team estimated that every 20% drop in antidepressant use among all ages in the US would lead to a nearly 10% increase in suicides — an additional 3,040 deaths per year.
Another study by Greg Simon and James Savarino at Group Health Cooperative in Seattle revealed that the pattern of suicide attempts before and after starting antidepressant treatment was not specific to the type of medication used. This study found that the differences between treatments and changes over time probably reflect referral patterns and the expected improvement in suicidal ideation after the start of treatment.
SSRIs include Prozac, Zoloft and Paxil. According to Mental Health America, approximately 16 million Americans take SSRIs.
The Food and Drug Administration originally required black-box warnings on SSRIs in 2003 and 2004 because according to research, youths who took the drugs showed an increase in suicidal thinking. At that time, the warning applied specifically to patients younger than 19. But earlier this year, the warning was changed to include adults younger than 25.
However, an editorialist astutely observed that “it is much more likely that suicidal behavior leads to treatment than that treatment leads to suicidal behavior.” Many experts argued that the FDA warnings would cause many patients to abandon treatment that they desperately need. Currently, at least 3 million Americans do not receive any treatment for their depression.
But these new studies provides the strongest evidence yet that SSRIs actually do prevent suicide in children and teens as well as in adults.
“If the intent of the black-box warning was to save lives, the warning failed,” Gibbons’ team wrote in their paper. ” . . . What should be considered instead is better education and training of physicians.”
