Newer
antidepressants,
already
suspected
of
raising
the risk
of
suicide,
may also
cause a
few
people
to
become
violent,
researchers
reported
on
Monday.
They
found
that
people
who took
GlaxoSmithKline's
antidepressant
Paxil
were
twice as
likely
to have
what was
called a
"hostility
event"
as those
given a
placebo.
Paxil,
known
generically
as
paroxetine,
is in a
class of
drugs
called
selective
serotonin
reuptake
inhibitors
or
SSRIs.
They
came
under
scrutiny
when
some
doctors
reported
that
teenagers
taking
the
drugs
might be
more
likely
to
commit
suicide.
In 2004,
the U.S.
Food and
Drug
Administration
concluded
there
was a
higher
risk of
suicidal
behavior
among
children
and
teenagers
and
ordered
strong
label
warnings
on
several
SSRI
drugs.
It has
urged
close
monitoring
of
adults.
David
Healy
and
David
Menkes
from
Cardiff
University
in
Britain
and
Andrew
Herxheimer
from the
Cochrane
Center
used
several
sources
of
information
to see
what the
risk of
violent
behavior
was
among
people
taking
SSRIs.
They
included
data on
paroxetine
presented
to
Britain's
Committee
on
Safety
of
Medicines
Expert
Working
Group by
GlaxoSmithKline,
legal
cases
and
e-mails
from
1,374
patients
in
response
to a
British
television
program
on the
subject.
They
found
that 60
out of
9,219
people
who took
Paxil or
0.65
percent,
had "a
hostility
event,"
compared
to 20 of
6,455
given a
placebo,
or 0.31
percent.
Writing
in the
online
journal
Public
Library
of
Science-Medicine,
the
researchers
said,
however,
that
such
violence
was
likely
to be
rare.
