ACNP – a pharmaceutical industry funded association of psychiatrists – claims SSRI Antidepressants don’t increase suicidal behavior
Wed, 21 Jan 2004
The American College of Neuropsychopharmacologists (ACNP), an organization of psychiatrists with significant financial support from the manufacturers of psychotropic drugs, announced that a study it sponsored found that SSRI antidepressants did not increase the risk of suicide in children and adolescents. However, ACNP did not release the study, only an executive summary. The early announcement of this “positive” finding smacks of a public relations ploy as it comes just before FDA’s advisory committee meeting (Feb 2, 2004).
Clearly, ACNP is attempting to deflect the impact of an alarming body of previously concealed evidence uncovered by the British medicine authority. The independent British review of the unpublished company data from controlled clinical trials in children and adolescents, revealed that SSRIs were not beneficial for children and that children who took the drugs were at two-to-threefold increased risk of becoming suicidal.
These alarming findings led the British authority to ban (first Paxil) then the other SSRIs for use in children. FDA issued a public health advisory statement– though not a warning in the drugs’ labels. Public disclosure of those findings led GlaxcoSmithKline (GSK) to issue warnings to UK doctors against using Paxil in children. On June 18, 2003, GSK acknowledged an increased suicidal risk for children prescribed Paxil. See: https://www.ahrp.org/risks/PaxilRisks0603.php. On Aug 22, 2003, Wyeth Pharmaceuticals followed suit and issued a warning to UK and US doctors not to prescribe Effexor for children. See: https://www.ahrp.org/infomail/03/09/02.php
In December 2003, Eli Lilly informed UK doctors (but not US doctors) that Prozac is “not recommended” for children. See: https://www.ahrp.org/risks/ProzacKids1203.php
Curiously, ACNP’s optimistic findings contradict the findings of the British authority, the evidence cited by the FDA, and even the warnings issued these drug manufacturers.
Insofar as the drug industry provides substantial financial support to the ACNP–and to members of its SSRI task force–ACNP’s disclaimer statement is disingenuous: “The ACNP Task Force on SSRIs and Suicide was supported solely by the ACNP. There was no financial support from the pharmaceutical industry for this Task Force.”
New Report Concludes SSRI Antidepressants Do Not Increase Suicidal Behavior in Youth with Depression ACNP Presents Findings As FDA Opens Hearings
WASHINGTON, Jan. 21 /PRNewswire/ — SSRI* antidepressants do not increase the risk of suicidal thinking or suicide attempts in youth, according to a new report released today by the American College of Neuropsychopharmacology (ACNP). The report also noted that several SSRIs have been shown to be effective for treating depression in this population. ACNP appointed a special task force of the nation’s leading scientists in the field to review the available research on the use of antidepressants and youth under 18 years of age.
“The evidence linking SSRIs to suicide is weak,” said J. John Mann, M.D., Co-Chair of the ACNP Task Force and Professor of Psychiatry at Columbia University College of Physicians and Surgeons, and Chief, Department of Neuroscience, New York State Psychiatric Institute. “There are strong lines of evidence in youth — from clinical trials, epidemiology and autopsy studies — that led the ACNP Task Force to conclude that SSRIs do not cause suicide in youth with depression.”
ACNP established the Task Force after regulatory agencies in the United States and United Kingdom voiced concerns in 2003 about the possibility that treatment of depression in children and adolescents with SSRIs may increase the risk for suicide. The FDA is convening an advisory committee hearing to review the issue on Feb. 2, 2004.
“The most likely explanation for the episodes of attempted suicide while taking SSRIs is the underlying depression, not the SSRIs,” said Graham Emslie, M.D., Co-Chair of the ACNP Task Force and Chief, Division of Child and Adolescent Psychiatry and Professor of Psychiatry, The University of Texas Southwestern Medical Center at Dallas. “The potential benefits of SSRIs outweigh the risks.”
The ACNP Task Force reviewed clinical trials of more than 2,000 youth and found that there were no statistically significant increases in suicide attempts, self-harm, and suicidal thinking related to SSRI use. Importantly, they found that there were no suicide deaths in any of the trials.
The ACNP Task Force concluded that if anything, the increased use of SSRIs appears to have lowered the risk of suicide worldwide based on a review of epidemiology studies from several countries. The group noted that the rate of youth suicide in 15 countries has declined by an average of 33 percent over the past 15 years. This period of time coincides with increases in prescribing rates for SSRIs.
The ACNP Task Force also cited an autopsy study, which suggests that suicide is more likely when depressed individuals do not take their medication, rather than when they take it. A study of adolescent suicides found that of the 24 percent who had been prescribed antidepressants, none tested positive for SSRIs at the time of their death.
The Task Force found several SSRI trials that showed efficacy in treating depression in youth, while other trials failed to demonstrate efficacy. They noted that differences in drug effectiveness across clinical trials may be from differences in methodology and recommended additional study.
The report concluded that another category of antidepressants known as tricyclics were ineffective in patients under 18 years of age. Other forms of treatment were found to be not widely available to youth, or insufficient data were available to support their effectiveness.
Childhood depression is a serious public health problem that carries the risk of suicide. ACNP urged clinicians to ask depressed patients about suicide, suicidal thinking, and plans for suicide.
The report also includes research and regulatory recommendations. ACNP urged that all data held by FDA or pharmaceutical companies should be made rapidly available to allow ACNP and other research organizations to conduct an independent evaluation of the risks and benefits of SSRIs in youth and adults with depression and other mood disorders.
Evidence reviewed includes all published clinical trial data in youth. The Task Force also obtained and reviewed unpublished data from several drug companies and data reported to the United Kingdom’s drug regulatory agency.
“The Task Force emphasizes that its findings and recommendations are preliminary,” said Mann. “While ACNP reviewed all published data and some unpublished data, it does not have access to a substantial amount of data available to the FDA or to pharmaceutical companies.”
The full version of the ACNP Task Force report will be released in the spring or early summer of 2004. For a copy of the executive summary of preliminary findings, visit www.acnp.org or call Betsy Murrett at 202-745- 5107.

ACNP is a non-profit, professional society with revenues from a variety of sources including membership dues, publication sales, registration fees, and unrestricted educational grants from the pharmaceutical industry. The ACNP Task Force on SSRIs and Suicide was supported solely by the ACNP. There was no financial support from the pharmaceutical industry for this Task Force.
* SSRIs or Selective Serotonin Reuptake Inhibitors are a widely used category of antidepressants, which includes such drugs as fluoxetine (Prozac(R)) and paroxetine (Paxil(R)).
