April 21, 2001   "Zoloft Suicide Tragedy Matt Miller (13)"
But then he began showing signs of intense nervousness and agitation. He couldn't sit still, his father remembers. He kept kicking people under the table. His eyes were sunken and he couldn't sleep, yet he had a restless energy.
After six days on the drug, on July 28, 1997, Matt hanged himself in his bedroom closet.
"Suicide always takes you by surprise, but no one could have imagined that Matt would have done that," Miller said in an interview. "There was no previous attempt, no serious threat of it, no note, no premeditation. "It was a very impulsive act I am convinced was brought about by the stimulant nature of the drug."
Miller has launched a lawsuit against Pfizer Inc., which makes Zoloft. He is one of about 200 people who have sued -- so far unsuccessfully -- the makers of Prozac and similar products. The plaintiffs contend that the drugs, known as selective serotonin reuptake inhibitors, caused their loved ones to kill themselves and, in some cases, hurt or kill others as well. One of the few cases to go to trial so far was that of William Forsyth, a 63-year-old wealthy Hawaii businessman who stabbed to death his wife of 37 years and then killed himself in 1993. At the time, he had been taking Prozac for 11 days for panic attacks.
In 1999, a jury in the civil lawsuit cleared Prozac of liability in the deaths. Forsyth's adult children began another suit last year accusing Eli Lilly and Co., the maker of the drug, of covering up damaging details about the antidepressant.
Chief among the scientific experts who have given people, including Miller and Forsyth's children, reason to believe that a link may exist between antidepressants and suicide is Dr. David Healy, whom Miller has engaged as an expert witness in his suit.
Healy is a well-known British psychiatrist who argues that Prozac and similar drugs may trigger suicide in some patients, and that there should be warning labels on the products.
To Miller, Healy is a hero, a crusading scientist with the guts and credibility to challenge the powerful, multinational drug companies in an era in which many researchers and institutions depend on them for funding. But discussing the down side of Prozac does not appear to have been a good career move. Healy's blunt expression of his views may have cost him a job at the Centre for Addiction and Mental Health, a teaching hospital associated with the University of Toronto. The centre had been recruiting him for months, but last year rescinded his written job offer after he gave a speech warning that Prozac may trigger suicide in some patients.
Eli Lilly Canada Inc. is a major corporate donor to the centre, but university and hospital officials say their decision had nothing to do with wanting to please the drug company or to avoid damaging future fundraising efforts. They say their reasons are confidential. Healy says the only explanation he was offered was that his lecture "solidified" the view that he was not a good fit.
For Eli Lilly's part, it points out that a U.S. Food and Drug Administration panel of experts voted six to three against requiring Prozac to carry a suicide-risk warning label. In September of 1991, the FDA concluded that there was no credible evidence of a causal link between the use of antidepressant drugs, including Prozac, and suicides or violent behaviour. And a paper published in March of 1991 by Jerrold Rosenbaum of Massachusetts General Hospital found that patients on Prozac were not prone to suicide any more than patients on other medication.
Eli Lilly said, in a written response to questions from The Globe and Mail: "There is, to the contrary, published scientific evidence showing that Prozac and medicines like it actually protect against such behaviour -- reducing aggressive and suicidal thoughts and behaviour."
When Prozac was introduced in the late 1980s, it was billed as a wonder drug that could combat depression with far fewer risks than previous medications, including the danger of an overdose or problems when mixed with alcohol. Prozac and drugs like it -- Zoloft, Paxil and Luvox -- were said to help with emotional limitations such as low self-esteem and fear of rejection. Prozac was a commercial as well as a medical miracle, sold to an estimated 40 million people worldwide since it hit the market.
The drug boosts levels of the neurotransmitter serotonin, which seems to improve the mood of patients. But within a few years of Prozac's launch came hints that it brought out a dark side in a small fraction of users. Martin Teicher, a researcher at Harvard University, published an article in the American Journal of Psychiatry in 1990 that discussed six cases in which patients became intensely preoccupied with suicide after taking the drug. Other scientists also found a potential link between Prozac and suicide.
Healy says in one of his published papers that Eli Lilly scientists collaborated with the FDA on designing an experiment that would measure how serious the problem was, but they then decided against conducting it. Instead, in 1991, Eli Lilly published an analysis of data taken from existing trials. Its conclusion? There was no increase of suicidal thoughts or suicide among depressed patients taking Prozac.
But Healy says in the paper that data from only about one-eighth of the patients in the clinical trials were included. No mention was made that some had been prescribed a sedative that may have alleviated an intense nervous state that can lead to suicide, which is called akathisia, he says. The analysis also did not point out that 5 per cent of patients dropped out of the studies because they were anxious and agitated and may have been suffering from akathisia, Healy says.
Another document, dated Nov. 13, 1990, shows that company scientists were pressured by executives to soften physicians' reports of suicidal thoughts or suicide attempts, according to Harvard psychiatrist Joseph Glenmullen, who obtained the document and is author of the book Prozac Backlash. Additional evidence about the potential risks can be found in the patent for a second-generation Prozac pill, which Eli Lilly has licensed. The patent says the new and improved Prozac would decrease side effects including: "nervousness, anxiety, and insomnia," as well as "inner restlessness (akathisia), suicidal thoughts and self-mutilation."
But at the same time, Eli Lilly says these symptoms are not associated in any significant way with taking the current version of Prozac. The new Prozac -- which incidentally was co-developed by Teicher, one of the drug's early critics -- isn't yet on the market, Last year, Healy published a study in the journal Primary Care Psychiatry that said two of 20 healthy volunteers taking an antidepressant in the same family as Prozac reported feeling suicidal.
But by his calculations, probably 40,000 people have committed suicide while on Prozac since its launch, above and beyond the number who would have taken their own lives if their condition had been left untreated.
The German government now requires warning labels, and Britain is considering them. Canada and the United States do not. Healy says he is not opposed to Prozac and thinks that it can do a lot of good. But he says it is unethical and irresponsible not to warn doctors about the potential dangers, and believes Eli Lilly chose not to do so to maximize profits.
He says family doctors seem to be increasingly prescribing Prozac and other antidepressants to children and now to women complaining of severe premenstrual symptoms, yet patients in North America do not have to be told about the potential risks.
Eli Lilly and the other drug companies argue that depression, not antidepressants, are to blame for suicides. Pfizer is trying to have Healy barred from testifying in the Miller case, questioning his credibility as an expert witness.
So what are Canadian consumers to think? Jacques Bradwejn, chairman of the psychiatry department at the University of Ottawa, says he has reviewed the literature and agrees with the FDA and Eli Lilly that there is no evidence that Prozac and similar drugs cause more suicides than would have occurred if patients had not been treated.
But a small number of patients -- even as many as 1 per cent -- may fall into a nervous state that could trigger suicide, he said, adding that more research is needed to better understand the problem.
While Prozac may be overprescribed for patients who are not truly ill, Bradwejn worries that the message that the Prozac is dangerous will do more harm than good for those who are moderately to severely depressed. "If the message is too alarmist, it could have a very negative effect on Canadians."
A study by Dr. David Healy found that two of 20 healthy volunteers taking a selective serotonin reuptake inhibitor in the same family as Prozac reported suicidal feelings. This is the story of one of those people, a 30-year-old woman who didn't know what drug she was taking, as recorded in the study. "On the Friday she telephoned early in the morning, distressed and tearful from the previous night. Her conversation was garbled. She described almost going out and killing herself. . .
"The night previously she had felt complete blackness all around her. . . . She felt hopeless and alone. It seemed that all she could do was to follow a thought that had been planted in her brain by some alien force. "She suddenly decided she should go and throw herself in front of a car, that this was the only answer. It was as if there was nothing out there apart from the car. . . . She didn't think of her partner or child. She was walking out the door when the phone went. This stopped the tunnel of suicidal ideation.
"She later became distraught at what she had nearly done and guilty that she had not thought of her family."
