Taking Antidepressants But Still Sad
cont. from
The boom and bust
From 1988, when
Prozac (the first
SSRI) was introduced in the U.S., to
1998, prescriptions for antidepressants tripled from 40 million to 120
million, fueled largely by the popularity of that "celebrity pill."
Radically different from the previous generation of antidepressant
medication, mostly because overdosing was unlikely, the SSRIs at one point
were seen as so personally transforming that even people who were not
clinically depressed took them for a little performance boost.
By 2004, nearly 150 million U.S. prescriptions were written for the
drugs, and they represented the third-largest selling class of medicines
after cholesterol and ulcer drugs.
But last year, U.S. sales of these medications, while still sixth in the
leading classes of therapeutic drugs, dropped sharply, according to IMS
Health Inc. a Fairfield, Conn.-based tracker of prescription drug data. And
prescriptions for patients 18 and younger have plunged by 20% since 2004
when the
suicide issue was raised at FDA hearings, according to NDC Health
Corp., an Atlanta healthcare information provider.
Dr. Judith Bucholtz, a psychotherapist in Brentwood, says that several
years ago nearly half the people who came to her for
psychotherapy were also
taking antidepressants. Today, only three of 20 patients are using the
drugs. "There seem to be more and more people who are reluctant to take
these medications," she says. "There was more confidence in them before the
FDA hearings."
The much-publicized hearings focused on the association between
antidepressant medication and suicidal thoughts among children and
adolescents. The following October, the FDA told makers of
antidepressants
to place a black-box warning on the drugs stating that antidepressants can
cause
suicidal actions in children and adolescents. Last year, the FDA
modified its warning, saying the drugs "increased the risk of suicidal
thinking and behavior in short-term studies of adolescents and children"
with depression.
The FDA placed no such warnings about the medications' effects on adults.
But in July 2005, the agency nonetheless issued a public health advisory to
alert patients and healthcare providers that there may be a possibility of
increased suicidal behavior in adults treated with antidepressants.
However, a 10-year study that also appeared in the January issue of the
American Journal of Psychiatry looked at the health plan records of more
than 65,000 patients and could find no evidence that antidepressants caused
suicidal thoughts. In fact, it found that the number of suicide attempts
actually fell by 60% in adults during the month after they began taking the
medicine.
"The irony and the lost message is that the risk of suicide in depression
is very real and very clear," says Leuchter. "But the risk of increasing
suicidality in treatment is vanishingly small."
The sheer dimensions of depression illustrate the importance of
treatment. A massive study conducted by the World Health Organization,
Harvard University School of Public Health and the World Bank, found that by
the year 2020, depression will be second only to heart disease in terms of
disability caused. In any one-year period, 9.5% of the population, or about
18.8 million American adults, suffer from a depressive disorder, according
to the National Institute of Mental Health. And though less than half seek
treatment, many try to get help from their primary care physician or, less
frequently, a mental health professional.
As currently offered, even treatment is no guarantee that the depression
will lift.
Veering off course
Jennifer, a 38-year-old Web designer from Castro Valley, has struggled
with depression since 1996. When she was most depressed, the only reason she
didn't kill herself was because she simply couldn't summon the energy to do
it.
She couldn't think, couldn't work and barely managed to emerge from her
bedroom for days on end. When she went out, usually to a therapy
appointment, she would shop compulsively, spending money she didn't have.
She would then retreat, once again, into the isolation and paralysis of her
home. Sometimes more than a week would slip by before she took a shower.
Then her psychiatrist prescribed the antidepressant
Trazodone. The
depression eventually lifted but she was left "feeling dead," she says.
"I was just blah, as if there were nothing to feel. I didn't get too
happy or too sad and my libido was completely gone." She had been a computer
programmer, but the medicine left her so addled cognitively that "it didn't
make sense any more. It was like being a math whiz and not able to do simple
algebra."
For 10 years she would take various medications that her doctors
prescribed, then abandon them when the
side effects bothered her or the
medicine didn't seem to be working after a few days. Being urged to stick
with it, or to keep taking the medications even when she felt a bit better,
didn't persuade her.
"The side effects are immediate, but the beneficial effects take some
time," says SUNY's Schwartz. "So if people don't have a relatively quick
response, they give up. These drugs take weeks to be effective but often
people think, 'These are mental medicines — they shouldn't have a physical
side effect.' "
Psychiatrists have attempted to more completely understand the
mysteries of "treatment compliance" or, more simply, why some people will
take their medicine while many just stop.
In a 2005 study in the journal General Hospital Psychiatry, researchers
attempted to identify what made people continue, discontinue and switch
their SSRI medications over a nine-month period.
