A visibly irritated woman yanks on a supermarket shopping cart that's stuck in its stack while a soothing female voice-over recites a litany of PMS symptoms. She asks, "Think it's PMS? Think again. . . . It could be PMDD."
Premenstrual Dysphoric Disorder, or PMDD, is a fresh-minted mental illness that purportedly affects 3 to 10 percent of all menstruating women. Mood symptoms like depression, anxiety, anger, irritability, or sensitivity to rejection are said to be so severe the week before a woman's period that it impairs her functioning. According to Dr. Jean Endicott, professor of clinical psychology at Columbia University's College of Physicians and Surgeons, "What's ordinarily irritating becomes enraging."
To be diagnosed with PMDD, women must keep a daily diary of their symptoms for the duration of two menstrual cycles. The symptoms must kick in after ovulation and disappear once menstruation begins. "The timing is exquisite," remarks Endicott.
The timing is also exquisite for Eli Lilly and Company to make a financial killing off of PMDD. Next year, the drug company will lose its patents on the antidepressant Prozac, and with them its monopoly on the market. To ward off declining profits, Lilly has found another use for its wonder drugtreating PMDD.
In July, Lilly got Food and Drug Administration approval to market Prozac under the new name Sarafem. The company is packaging the drug in pretty pink and lavender capsules, exclusively for women, most in their late twenties or early thirties. Says Laura Miller, a spokesperson for Lilly, "Women told us they wanted treatment that would differentiate PMDD from depression."
According to Endicott, the symptoms of PMDD primarily interrupt "interpersonal relationships"basically, those involving spouses, children, and coworkers. In one group of women with self-described premenstrual symptoms, researchers found no increase in absenteeism or decline in work performance, although the women themselves perceived that to be the case.
"PMDD is unique because there is virtually no other disease that people insist upon having," says Dr. Nada Stotland, chair of psychiatry at Illinois Masonic Medical Center. According to Stotland, the majority of women who go to PMS clinics have symptoms that aren't in fact related to their periods. "Most are depressed everyday. Others have anxiety and personality disorders. Some are in psychological pain because they are being abused."
That women might seek help on the pretense their problems are hormonally based makes PMDD more slippery to recognize and study. Stotland says she's particularly concerned that Lilly is targeting almost exclusively OB-GYNs as Sarafem prescribers, which puts gynecologists in the position of treating mental illness. She says Lilly's advertising campaign may convince enough women they need Sarafem, leading them to pressure their doctors to skip the two months needed for diagnosis and instead send them straight to the pharmacy. And since Sarafem will also work for those with chronic depression, a misdiagnosis can go undetected.
Proponents of Sarafem downplay the potential for misuse. "I doubt that a lot of people who don't need the treatment would get it," argues Endicott. "First, it's a prescription drug. Second, women are not big pill poppers." Sherry Marts, scientific director of the Society for Women's Health Researcha nonprofit organization that promotes research in women's health issuesconcurs. "This is a real medical condition that requires treatment for a small percentage of women," she says."Not, 'I'm a little bloated, I'm gonna pop some Prozac.' "
But critics claim that 3 to 10 percent of all menstruating women is no small number. "That's a minimum of half a million North American women suffering from PMDD," says Paula Caplan, a psychologist and affiliated scholar at Brown University's Pembroke Center for Research and Teaching on Women.
Whether PMDD is a real condition is still subject to debate. Although both sides agree that a certain subset of women may be sensitive to normal hormonal changes, that's about all they agree on. The question remains, if women sometimes snap at their husbands if they don't pick up after themselves, or at their kids if they do poorly in school, should they be branded with a mental disorder? "Women are commonly in situations defined by stressresponsibility without authority," says Stotland. 'That's almost the definition of a typical woman's job."
Some doctors fear that women who have legitimate reasons to be unhappy will be silenced by the PMDD diagnosis, and that Sarafem could prove to be the Valium of the naughts. "Ordinary, healthy changes in mood and emotion are being pathologized when they happen to women, and since women believe they shouldn't feel irritable, angry, or depressed, they are quick to blame themselves," says Caplan. For men, "There's no testosterone-based aggressive disorder."
Endicott disagrees. "If men had PMDD, it would have been studied a long time ago."
But would it? "To say that a huge proportion of the female population is disabled represents a potentially horrendous setback for women in the workplace," says Stotland. She points to the woman who finally speaks up to her boss and in return is asked, "Oh, is it that time of the month?" Agreeing to that kind of put-down might save the woman her job. PMDD could reinforce the stereotype of the hysterical woman not only to employers, but to women themselves.
Caplan says that a diagnosis of PMDD will have far-reaching legal implications as well. Might women who've been labeled as mentally ill be deprived of the right to make their own decisions? Might they lose custody of their children in divorce cases? In other words, will PMDD sufferers be seen as the biological equivalent of Dr. Jekyll and Mr. Hyde?
That's already the most common complaint of PMDD sufferers, says Endicott, who reports women saying over and over, "This isn't me." Lilly promotional literature echoes this sentiment. "The good news is there is treatment available that can help you feel more like the woman you are every day of the month," the brochures say. But who is this woman? And why are we so concerned with her hormones?
One thing is for sure: Eli Lilly and Company has a financial stake in PMDD. Lilly's Prozac patents are expiring in 2001 and 2003. This means the market will open up to cheaper generic competitors. Analysts have estimated that Prozac sales will decline drasticallyfrom about $2.51 billion in 2000 to $625 million in 2003. Sarafem will provide a significant new marketwomento boost profits. That's a smart move, since women are the primary users of drugs that alter mood. And, according to documents posted on the FDA's Web site, Lilly has proposed a "pilot study of PMDD in adolescents to estimate its response to treatment with fluoxetine." Fluoxetine, by the way, is the generic name for Sarafem (and Prozac).
Another plus for Lilly is that creating a new and separate trademark for Prozac lessens the stigma associated with antidepressants, and lets the company dodge some recent bad press, from the publication of Harvard's Joseph Glenmullen's Prozac Backlash to a new study in Brain Research that suggests the antidepressant may cut off axons of the nerves they targetin effect causing brain damage.
By 2004, Sarafem sales are expected to climb to $250 million a year, according to Bear Stearn's Bottle Report. Lilly would not divulge projected sales nor the amount of money spent marketing, researching, and developing Sarafem, but their financial report shows a lot of zeroes. For the first three quarters of this year, the corporation spent close to $2.3 billion in marketing and administrative costs, much more than its research and development, which totalled about $1.5 billion.
But most extraordinary is that the federal government is convinced of the existence of PMDD, while the psychiatric community isn't so sure at all. PMDD is currently listed in the appendix of the DSM-IVthe psychiatrist's bible of mental illnessesas "needing further study."
The controversy began in 1987, when the compendium first included specific criteria for Late Luteal Phase Dysphoric Disorderthe former name for PMDDin its appendix as a "proposed diagnostic category" needing more research. In 1993, as the American Psychiatric Association's task force was compiling the fourth edition of the manual, the category was revisited. Should it remain in the appendix, get moved to the body as a recognized diagnostic category, or be removed altogether?
The committee decided to keep PMDD in the appendix. According to Psychiatric News, the APA's professional newsletter, "Members of the task force agreed there were a number of problems with methodology within the PMDD literature. The problems included unclear definitions, small sample sizes, lack of control groups, lack of prospective daily ratings of symptoms, no documentation of the timing and duration of symptoms, and failure to collect appropriate hormonal samples." However, the committee suggested specific criteria for diagnosing PMDD, including specs for symptoms and timing.
Five years later, the fate of PMDD was still unclear. In October 1998, the Society for Women's Health Research organized a discussion, headed by Endicott, to answer this question: "Is premenstrual dysphoric disorder a distinct clinical entity?" Once again, experts reviewed the PMDD literature, this time in the company of FDA and Lilly representatives.
Dr. Sally Severino, a now retired professor of psychiatry at the University of New Mexico, reiterated flaws in the research. First, just because women can be identified by PMDD criteria "is not proof that PMDD exists as a valid diagnosis." Second, although cross-cultural studies identified physical complaints related to menstruation, mood symptoms like anger and irritability were not found worldwide to the same degree as in America. Severino argued that if PMDD can't be identified in other populations, then "consideration must be given to the criticism that PMDD is a culturally bound syndrome or an unnecessary pathologizing of cyclical changes in women."
Ignoring these objections, the round table concluded that PMDD was a "distinct entity with clinical and biologic profiles dissimilar to those seen in other disorders." In other words, a mental illness.
What changed between 1993 and 1998? For one thing, Lilly funded a 1995 study that showed Prozac was effective in treating PMDD. Published in The New England Journal of Medicine, the study had a large sample size, and was placebo-controlled and double-blind (meaning neither the doctor nor the participant knows who's getting drugs or a sugar pill)all the makings of a pristine scientific inquiry. A slate of studies followed suit, all with the same results: About 60 percent of women diagnosed with PMDD respond to Prozac.
Yet one 1998 study discussed by Endicott's roundtable found that 55 percent of women diagnosed with premenstrual symptoms got significant relief from increased calcium intake. The group went on to comment that "the area of calcium is not well explored." That leads critics to wonder why other treatment options are getting the cold shoulder. "Why not spend pages and pages pushing calcium?" asks Caplan, who served on the 1993 DSM committee. And although there is evidence that people with PMDD can feel better with only intermittent doses of Prozacand suffer fewer side effects like sexual dysfunctionthe studies Lilly presented to the FDA looked solely at the effectiveness of daily doses, or roughly double the amount some researchers say is needed.
According to Caplan, almost all of the data the roundtable evaluated fell into two categories: the old problematic studies available to the DSM-IV group or the new research into using Prozac to treat PMDD. "There was nothing that looked at the validity of the PMDD construct," says Caplan.
Did Lilly railroad Sarafem through? Two members of the 16-person roundtable conducted PMDD research funded by Lilly, and another member has received honoraria as a speaker for Lilly. Endicott, who hasn't received research funds or speaking fees from Lilly, opened the company's November 1999 presentation to an FDA advisory committee, which voted unanimously in favor of the new PMDD indication for Prozac. In addition, the Society for Women's Health Research trumpets on its Web site an "unrestricted educational grant from Eli Lilly and Company," which they've used to promote PMDD awareness, including a national survey conducted in November to gauge women's awareness of PMDD and available treatment (i.e., Sarafem). "Lilly had done an extraordinary job of getting this to the public," says Stotland.
Researchers taking a ride on the drug-company gravy train is not unique to those who studied PMDD, but it can have effects on scientific research. "I don't think people falsify results. But what kinds of questions do you ask? Which results do you publish?" asks Stotland. "When I was a resident it was the departments who had money to bring in speakers. Now, it's the drug companies who are flying people around."
Incidently, at the time of the interview, Stotland was attending a PMDD conference held at a Palm Springs resort, courtesy of Eli Lilly.
