An in-depth analysis of clinical trials reveals widespread underreporting of negative side effects, including suicide attempts and aggressive behavior
Antidepressants are some of the most commonly prescribed medications out there. More than one out of 10 Americans over age 12—roughly 11 percent—take these drugs, according to a 2011 report by the National Center for Health Statistics. And yet, recent reports have revealed that important data about the safety of these drugs—especially their risks for children and adolescents—has been withheld from the medical community and the public.
In the latest and most comprehensive analysis, published last week inBMJ (the British Medical Journal),a group of researchers at the Nordic Cochrane Center in Copenhagen showed that pharmaceutical companies were not presenting the full extent of serious harm in clinical study reports, which are detailed documents sent to regulatory authorities such as the U.S. Food and Drug Administration and the European Medicines Agency (EMA) when applying for approval of a new drug. The researchers examined documents from 70 double-blind, placebo-controlled trials of two common types of antidepressants—selective serotonin reuptake inhibitors (SSRI) and serotonin and norepinephrine reuptake inhibitors (SNRI)—and found that the occurrence of suicidal thoughts and aggressive behavior doubled in children and adolescents who used these medications.
