Taking Antidepressants But Still Sad
Antidepressants aren't the magic that millions hoped. For the first
time, prescriptions fall.
(March 27, 2006) -- The nation's heady romance with antidepressant
medication appears to be over.
First came the warning of a possible
link between selective serotonin
reuptake inhibitors and suicidal thoughts among children and adolescents.
Then came a drop in sales — 14% last year compared with the year before. Now
research has found that a single medicine typically
does not effectively
treat depression for most people and that those with
depression often stop
taking the medicines altogether.
"The problem is not that the drugs don't work. They do. The challenge is
we can't predict who will get well with what medicine," says Dr. Andrew
Leuchter, vice chairman of the department of psychiatry at the David Geffen
School of Medicine at UCLA.
With that increased understanding — of both the illness and the treatment
— has come an attempt to craft more balanced, realistic therapies.
As Dr. David Kupfer, chairman of the University of Pittsburgh School of
Medicine's psychiatry department, points out: "The problem of not treating
is much more dangerous than all the problems we get into by treating the
illness."
Clearly, a one-size-fits-all approach will not suffice. Patients who
complained to their internists about feeling blue have not been well-served
by simply a prescription for an SSRI — and few warnings about side effects
or the very real possibility that the drug might not work.
"Depression is no different from epilepsy or diabetes or hypertension: No
one treatment is sufficient for a majority of patients in all medical
diseases," says Dr. Madhukar Trivedi, the head of a recent study on
antidepressants and a psychiatry professor at the University of Texas
Southwestern Medical Center in Dallas.
His study, published in the January issue of the American Journal of
Psychiatry, found that a single SSRI medication works only for about 30% of
chronically depressed patients. For most of the 2,876 outpatients
participating in the study, real progress came only with subsequent drugs or
with a combination of drugs.
A second study from the same group, published Thursday in the New England
Journal of Medicine, looked at the remaining patients who did not respond to
the single medication the first time. More than half of this group switched
medications completely, and about a quarter of them became symptom-free
within 14 weeks. An additional 565 augmented the initial antidepressant with
a second medication, and within 14 weeks of treatment, one-third became
symptom free.
But many patients have been too shy or too discouraged — and many primary
care physicians not up to speed on sophisticated approaches — to pursue this
more complex treatment.
Between 70% and 80% of people with depression receive their treatment not
from a psychiatrist but from a primary care doctor. And these doctors
typically prescribe one medication in the hope that it will work. As these
studies reveal, most of the time it doesn't.
"Most depression is treated in primary care. And while they do a good job
with a lot of things, they often don't follow up as well as psychiatrists
do," says Dr. Thomas Schwartz, a professor of psychiatry at SUNY Upstate
Medical University in Syracuse, N.Y. "Part of our job is to come up with
alternatives for our patients. Often we end up adding medications so they
work together."
Lindsey, a 28-year-old Palm Desert resident, knows this firsthand. Since
she was 17, she's been through an alphabet soup of medications, each with
various side effects.
Effexor "sucks in terms of your sex life."
Zoloft "just didn't work."
Wellbutrin triggered urinary incontinence. And the lithium that she was
given when her depression was thought to be bipolar disorder caused her to
develop jerky movements and gain 50 pounds.
After suicide attempts and dismal reactions to the medication, and a
descent into substance abuse that finally led her to the Betty Ford Center,
she has found a psychiatrist she trusts — one who has tweaked her
Effexor
with a low dose of Wellbutrin. After all, repeated research has shown that
the most effective treatment for depression is medications along with
psychotherapy. With that approach, she is losing weight and has managed to
get, and hold down, a job.
"Of course, if I knew then what I know now, so much pain could have been
avoided," says Lindsey, who, like the other antidepressant users quoted in
this story, did not want her last name used. "I was feeling really hopeless
in trying out all these different drugs and not having them work."
As many patients learn, the key to effective treatment for depression —
as with most illnesses — is giving the medications time to work and knowing
when they aren't.
"What we should be doing is starting from the get-go and telling patients
and families, you may not respond to this treatment alone," says University
of Pittsburgh's Kupfer. "We think we are allowed to use one drug, one
bullet. If we were treating cardiovascular disease or asthma, we would be
talking about a treatment strategy over a lifetime."
The newer, more measured view of antidepressants should not have been
entirely unexpected, points out Fred Goodwin, the former head of the
National Institute of Mental Health and professor of psychiatry at George
Washington University. Every drug has a life cycle, he says.
First, it's called a magic bullet that will save the world.
Prozac's history can attest to that. As the first SSRI, the green pill was
featured on the cover of Newsweek in 1989, and the 1993 book "Listening to
Prozac" spent months on the bestseller list.
Then comes the backlash. For antidepressants, that stage reached its peak
during the Food and Drug Administration hearings in February 2004 where the
message was: These drugs are killing our children.
Finally, it levels off somewhere in between, assuming its more reasonable
place in public perception.
Antidepressants now find themselves in that place.
