Patients often stop psychiatric drugs, with sometimes tragic consequences, therapists say
CHICAGO (AP) _ Psychiatrists say it's a common scenario — troubled
patients stop taking their medicine, because of cost, side effects, the
stigma, or delusions that they don't need it. The consequences can be
tragic, though rarely as horrific as the Valentine's Day
suicide-slaughter at Northern Illinois University.
No
one knows what triggered Steven Kazmierczak's campus rampage, yet one
of the clues to an emerging psychiatric profile is this: His girlfriend
says he recently stopped taking Prozac.
Prozac is a drug
generally prescribed for major depression. It and similar
antidepressants carry warning labels about risks for suicidal behavior
in patients younger than Kazmierczak, who was 27.
Still,
stopping these drugs can also lead to suicidal thoughts and behavior.
And taking them may increase the risk for other violence if they're
mistakenly prescribed as the only treatment for patients in a
depressive phase of bipolar disorder, psychiatrists say. In that case,
the drugs may trigger a manic phase that could include aggressive
behavior toward others.
In court cases, attorneys have sometimes
tried to blame violent behavior on Prozac. However, scientific evidence
to support that is lacking, and psychiatrists and the drug's maker, Eli
Lilly and Co., say the underlying mental illness is the most likely
culprit.
Kazmierczak, a graduate student in social work at the
University of Illinois, was a worrier with obsessive-compulsive
tendencies, his girlfriend told CNN, but it is not known if he'd been
diagnosed with depression or bipolar disorder. She said he'd stopped
taking Prozac three weeks before last week's tragedy.
Two days
before the Feb. 14 shootings, a New York man who'd been treated for
psychiatric problems and who had also stopped taking medication is
accused of fatally stabbing a therapist.
"Can stopping
medications be an important contributory factor to deterioration of
behavior ... where violence ends up being committed? Yes, absolutely,"
said Dr. Paul Ragan, an associate professor of psychiatry at Vanderbilt
University.
Ragan said he has had patients attempt suicide after
stopping antidepressants because their insurance ran out, although
violence against others is rare in depression.
On or off
medication, the vast majority of people with schizophrenia, depression
and bipolar disorder "do not engage in violent behavior," said Dr.
David Fassler, a University of Vermont psychiatry professor.
Still, compliance with medication is a significant problem, he said.
"Research
demonstrates that about 25 percent of patients stop taking
antidepressant medication within three months. By six months, some
studies suggest that the overall compliance rate is less than 50
percent," Fassler said.
For about one-third of patients, side effects are the main reason they stop taking psychiatric drugs, Fassler said.
Dr.
Lynne Tan, a psychiatrist at Montefiore Medical Center in New York,
said many patients complain that antidepressants cause restlessness,
agitation and racing thoughts. Sweating, sexual dysfunction and
headaches are other common side effects. Sometimes they subside over
time, and if not, patients can be switched to other medications, she
said.
Elizabeth, a 26-year-old graduate student in social work
at the University of Chicago who asked that her last name not be used
to protect her privacy, said she stopped and restarted antidepressants
many times since being diagnosed with depression at age 16.
"Stigma does play a big part of it," she said. "That's why I was so eager to consider myself well and to go off of it."
When
she left college and was no longer covered by her parents' insurance,
cost also became an issue — $60 to $70 a month for a generic
antidepressant. She declined to identify the drug.
But each time she stopped, debilitating depression including suicidal thoughts would return, she said.
"If I've learned anything from this journey, it's that medication really works for me," she said.
Greg
Coughlin, 53, a health department employee for DuPage County west of
Chicago, said several years ago he repeatedly stopped taking drugs for
a type of schizophrenia because he was "in denial" about suffering from
mental illness.
Coughlin said the last time he stopped, in the
1990s, he became extremely obnoxious and agitated, and ended up in a
mental hospital.
Now he's on three mood stabilizers that zap his
energy and cause weight gain, but make him feel "more solid, more
relaxed, more satisfied in life."
Coughlin, a board member of
the Illinois chapter of the National Alliance on Mental Illness, said
he finally accepts that to function, he'll need to be on drugs for life.
Elizabeth
said she can live with the side effects — extreme sweating and a hand
tremor — and credits psychotherapy, a support group and exercise with
helping her cope.
While accounts from friends and professors
suggest that at least on the surface, Kazmierczak was coping well,
there were also signs of trouble.
He had a history of cutting
himself, which is often a symptom of inner anger and a sense of feeling
powerless, said psychologist Wendy Lader, who runs a suburban Chicago
treatment center for self-cutters.
Self-cutting is thought to be
more common among women, but women are also more likely than men to
seek treatment for it, Lader said.
Kazmierczak also wore macabre
shock-value tattoos covering both forearms — an unusual and disturbing
choice for someone pursuing a career in social work, Lader said.
Dr.
Louis Kraus, a forensic psychologist with Rush University Medical
Center in Chicago, said with no known criminal background or history of
violence or anti-social behavior before the killings, Kazmierczak
presents a bewildering psychiatric image.
"Obviously something very tragic is missing from this puzzle that we don't fully understand yet," Kraus said.
