GSK's acknowledgement refutes the recent claims made in the official organ of the American Psychiatric Association, The American Journal of Psychiatry.
In the wake of the extraordinary acknowledgement this month by GlaxoSmithKline that the clinical trial evidence shows that not only children and adolescents are at increased risk of suicidal behavior if they take its antidepressant, Paroxetine / Paxil (or any other "new generation" antidepressant). Adults too are at increased risk of suicide if they take Paxil--and that risk is six-fold compared to those given a placebo.
Our colleague in the UK, Charles Medawar, of Social Audit, has been closely monitoring British public officials, drug company executives and leading academic psychiatrists--almost all of who have a financial / professional stake in protecting the reputation of SSRI antidepressants. His primary focus has centered on the British cast of characters in this tedious and insidious shadow play. GSK's acknowledgement confirms that the "authorities"--academic, government regulators and industry--have denied, deceived, and concealed evidence of drug harm.
The claimed findings reported by Dr. Gregory Simon and colleagues about their epidemiological study, Suicide Risk During Antidepressant Treatment, in The American Journal of Psychiatry 163:41-47, January 2006, vol. 163.1.41 are unsupported by the data. Dr. Simon reported that there was no increased suicide risk during the first week of treatment with an SSRI. This claimed finding from a methodologically flawed, uncontrolled study was widely disseminated in the major press--"Depression Drugs Safe, Beneficial, Studies Say" (Washington Post).
Uncritical reporters transcribed the investigators' claims without understanding that these were scientifically invalid.
However, Charles Medawar found egregious inconsistencies in that published report. He inquired, ever so politely, of Dr. Simon, the lead author to explain the inconsistencies.
The one sided correspondence reveals that academic psychiatrists have misrepresented what the data actually shows. "In agreement with Jick and colleagues (15), we found a significantly higher risk of suicide attempts in the first week of antidepressant treatment than in subsequent weeks".
In Dr. Simon's initial response, he conceded: "Risk in week 1 was not higher than in weeks 2, 3, and 4. But risk in week 1 was higher than in subsequent weeks (from week 5 onward)."
Uncorrected, inconsistent statements of findings confuse many readers: they serve to deflect from the very troubling evidence that these widely prescribed drugs pose a serious threat to those who take them--especially throughout the first month. Such misleading reports served industry's interests. http://www.socialaudit.org.uk/6060521.htm#ANTIDEPRESSANTS
The release simultaneously of two "positive" SSRI studies--both financed by the National Institute of Mental Health--seems suspiciously calculated. Our suspicions are validated by the accompanying editorial in the Amer. J of Psychiatry which questioned the need for the black box label warnings! (see below). It is especially troubling that that most of the uncritical media had accepted the claimed "positive" results on faith. But the report--like most of the scientific literature about SSRI antidepressant safety and efficacy provides false and misleading information tailored to conceal that these drugs induce suicides.
Since SSRIs have failed to demonstrate an antidepressant effect--given that in controlled clinical trials placebo has matched and even outperformed SSRIs--critics are beginning to wonder on what basis the FDA approved these drugs as "antidepressants"? This may be a case of misbranding.

Is the FDA Warning About Antidepressants Wrong?
A 2004 advisory by the Food and Drug Administration (FDA) warns that suicidal behavior may emerge after antidepressant treatment is begun. A 10-year population-based study by Simon et al. (p. 41 <http://ajp.psychiatryonline.org/cgi/lookup?lookupType=volpage&vol=163&fp=41 &view=short> ) indicates just the opposite. Among 65,103 patients in a large health plan who filled prescriptions for antidepressants during 1992-2003, the number of suicide attempts fell dramatically after antidepressant treatment began and then declined more slowly. Completed suicides were few and did not vary over the first 6 months of treatment. Adolescents had more suicidal behavior than adults, but attempts decreased by over 60% in the first month of treatment (see figure <http://ajp.psychiatryonline.org/cgi/content/full/163/1/A34#F1> ).
The FDA advisory names 10 newer antidepressants, but in this study the decrease in suicide attempts after treatment began was actually greater with newer agents than with older antidepressants. Reconsideration of the FDA warning thus seems warranted, as it discourages use of an effective treatment. ~~~~~~~~~~~~ 10 January 2006 Dear Dr. Simon,
I'm sorry to trouble you, but I wonder if you could help with this query arising from your recent paper (Am J Psychiatry 163:34A, January 2006) on Suicide Risk During Antidepressant Treatment.
In the text immediately preceding Figure 5, you and your colleagues noted that: "Suicide attempts during the first month of treatment were relatively evenly distributed throughout the month", (as Figure 5 shows). However, in paragraph two of the Discussion, you also noted that, "In agreement with Jick and colleagues (15), we found a significantly higher risk of suicide attempts in the first week of antidepressant treatment than in subsequent weeks".
Forgive if I've missed something, but I am unable to reconcile these two statements on the basis of the data and interpretations presented. I would be most grateful if you could clarify the position and put me right. Thank you for your attention and I look forward to hearing from you.
Sincerely, Charles Medawar Social Audit Ltd
11 January 2006 You are right - our language should have been more clear. Risk in week 1 was not higher than in weeks 2, 3, and 4. But risk in week 1 was higher than in subsequent weeks (from week 5 onward).
Greg Simon
11 January 2006 Dear Dr Simon,
Thank you for your mail, but your response raised further questions in my mind. If, as you say, the risk of serious suicide attempts in week 1 was not higher than in weeks 2, 3, and 4, it would seem to follow that the risks in first four weeks of treatment were greater than in subsequent weeks (from week 5 onward). Does this honestly justify the headline of your press release, "Suicide risk does not increase when adults start using antidepressants"?
Your paper also states that, "Among those treated with newer antidepressants (Figure 6) . risk in the first month of treatment was not significantly higher than in months 2 - 6". You attribute the increased risk in the first month of treatment to treatment with older antidepressant medications - yet you also acknowledge that, "older drugs were more often prescribed at the beginning of the study period, (1992 to June 2003) when the rates of hospitalization were generally higher".
Your paper noted that when you correct for this anomaly, "the risk of suicide death and the risk of suicide attempt were not significantly lower in patients treated with new drugs". Why was this seemingly important qualification not mentioned in your press release? "The study also found that the risk of suicidal behavior after starting 10 newer antidepressant medications is less than the risk posed by older medications".
I appreciate and share your general concern that people should not be deterred from taking antidepressants because they over-estimate the risk of drug-induced suicidal behaviour - but with these qualifications.
1. The headline in your press release, "Long-term, population-based study challenges FDA advisory" seemed unwarranted. It failed to acknowledge the critical lack of any placebo or control group in your study and, as you acknowledge in the small print of the paper, "our data certainly do not exclude the possibility that antidepressant drugs may precipitate increased suicidal ideation or suicide attempts in a sub-group of vulnerable individuals", and "an observational study such as this one can neither clearly establish nor clearly refute a causal relationship between antidepressant use and risk of suicide".
2. In a paper on "suicide risk during antidepressant treatment" (emphasis added), it did not seem appropriate to use as a prominent major benchmark the inevitably very high rate of suicidal behaviour that occurred in the month before drug treatment. That measure appears to be a cockshy: suicidality emerging before (and leading to) treatment clearly has nothing to do with the propensity of antidepressants to cause suicidal behaviour.
3. In the UK, and probably also in the US, about two-thirds of all prescriptions for SSRIs are for 'mild depression' (only 3% are for 'severe' depression), yet there is still no good evidence that SSRIs are more effective than placebo in treating cases of 'mild' depression. When there can be no expectation of significant benefit, what justification could there be for prescribing these drugs for people with mild depression, exposing them to significant risks? Did your study explore this, and do the prescribing practices recommended in the Group Health Cooperative take account of severity of depression?
I apologise in advance if my understandings seem to you limited or incomplete but considering the available evidence, alongside the interpretations and emphases added, I feel far from persuaded that no evidence of risk = evidence of no risk. I would welcome your comments on these further points.
Sincerely, Charles Medawar
11 January 2006 Could you please identify more clearly the purpose of your questions. Is this merely for our own information and interest?
Greg Simon
11 January 2006 Dear Dr Simon,
Thanks for your mail. Well, I hope my questions don't seem irrelevant, but no, they weren't simply for your own information and interest. You and your colleagues published a paper that reached conclusions with important implications, and I wrote to you because [a] I've been involved with and interested in this topic for some time; [b] I wasn't convinced that your research supported the main conclusions of your paper, let alone some of the interpretations and headlines arising from the GHC's press release; and [c] I thought you and your colleagues, having undertaken such a major study, might welcome feedback and the opportunity to further explain and justify your findings. Moreover, some of the points I raised - notably about the limitations of SSRI and other antidepressants in the treatment of mild depression - might perhaps be relevant to many GHC patients.
I have today posted to you a copy of Medicines out of Control? a study of psychotropic and antidepressant drug prescribing; this will give you more information about my interests and activities. You might also want to refer to our website (www.socialaudit.org.uk); though it has been rather neglected over the past six months, it still gets around 500,000 visitors/year. I might of course want to consider reporting on the issues your paper deals with and naturally it seemed sensible to first check with you about some of the queries I have.
I hope that this deals satisfactorily with your query and look forward to hearing from you.
Sincerely, Charles Medawar Social Audit Ltd
20 February 2006 Dear Dr Simon,
It's been some weeks since I wrote, I hope explaining the reasons for the questions I raised about your paper. I also sent you by airmail a copy of the book, Medicines out of Control? and I hope this arrived safely.
I am now writing to ask if and when I might expect a reply from you. I would appreciate your response on the points I raised.
Sincerely, Charles Medawar
19 May 2006 Dear Dr Simon,
I've been meaning to write to you for some time and the recent publicity about paroxetine provides a good opportunity to do so. This is to advise you that I shall shortly be posting a note on the Social Audit website about our correspondence earlier this year. You will see that the emphasis is on the need for accountability, rather than lack of courtesy. That seemed appropriate, given my views on the quality of your paper, and your conviction that there was never any need to defend it.
Sincerely, Charles Medawar
19 May 2006 Mr. Medawar -
I receive approximately 300 email messages a day. I simply can't respond at length to them all. If you would choose to raise questions about our paper, the usual method in the scientific community would be to write a letter to the editor of the journal publishing the paper. Please feel free to do that. I have responded to all questions raised through public channels. I do not have the time to repond to all private correspondence. If you value accountability, then you would certainly want all correspondence (including this message) to be public.
Greg Simon
21 May 2006 Dear Dr Simon,
Thank you for your mail. I appreciate that you would not be able to respond at length to 300 emails/day, but suspect you need a good spam filter. Thank you for telling me about protocol in the scientific community: I meant no offence when writing to first check with you about some of the queries I had about your paper, before writing to the journal concerned. However, I have now done so: see attached. I shall of course include our correspondence when I post to our website, and if you would like to comment further, of course you have the opportunity to do so.
Sincerely, Charles Medawar
