FDA Issues Public Health Advisory on Cautions for Use of
Antidepressants in Adults and Children
BETHESDA, MD -- March 29, 2004 -- The Food
and Drug Administration has issued a Public Health Advisory that provides
further cautions to physicians, their patients, and families and
caregivers of patients about the need to closely monitor both adults and
children with depression, especially at the beginning of treatment, or
when the doses are changed with either an increase or decrease in the
dose.
FDA has been closely
reviewing the results of antidepressant studies in children, since June
2003, after an initial report on studies with paroxetine (Paxil), and
subsequent reports on studies of other drugs, appeared to suggest an
increased risk of suicidal thoughts and actions in the children given
antidepressants. There were no suicides in any of the trials. On close
examination of the initial reports, it was unclear whether certain
behaviors reported in these studies represented actual suicide attempts,
or other self-injurious behavior that was not
suicide-related.
FDA has
initiated a full review of these reported behaviors by experts in such
evaluation. However, it is not yet clear whether antidepressants
contribute to the emergence of suicidal thinking and behavior. The agency
is advising clinicians, patients, families and caregivers of adults and
children that they should closely monitor all patients being placed on
therapy with these drugs for worsening depression and suicidal thinking,
which can occur during the early period of treatment. The agency is also
advising that these patients be observed for certain behaviors that are
known to be associated with these drugs, such as anxiety, agitation, panic
attacks, insomnia, irritability, hostility, impulsivity, akathisia (severe
restlessness), hypomania, and mania, and that physicians be particularly
vigilant in patients who may have bipolar disorder.
FDA is asking manufacturers to change the labels of
ten drugs to include stronger cautions and warnings about the need to
monitor patients for the worsening of depression and the emergence of
suicidal ideation, regardless of the cause of such
worsening.
The drugs under
review include bupropion, citalopram, fluoxetine, fluvoxamine,
mirtazapine, nefazodone, paroxetine, sertraline, escitalopram and
venlafaxine. It should be noted that the only drug that has received
approval for use in children with major depressive disorder is fluoxetine
(Prozac). Several of these drugs are approved for the treatment of
obsessive-compulsive disorder in pediatric patients, i.e., sertraline
(Zoloft), fluoxetine (Prozac), and fluvoxamine (Luvox). Luvox is not
approved as an antidepressant in the United States.
These interim actions follow recommendations made
by FDA's Psychopharmacologic Drugs and Pediatric Subcommittee of the
Anti-Infective Drugs Advisory Committees, which met on February 2, 2004.
The advisory committee members advised FDA that the labeling should draw
more attention to the need to monitor patients being treated with certain
antidepressants.
FDA has
previously noted (in Public Health Advisory and a Talk Paper T03-70
published Oct. 27, 2003) the possible finding of increased suicidal
thinking or behavior, but emphasized that it was not clear that the drugs
caused such events and additional analyses were being done to allow FDA to
seek more definitive answers.
The Public Health Advisory containing the new label
warnings and cautions is available online at http://www.fda.gov/cder/drug/antidepressants/default.htm.
Later this summer, FDA plans to update the Advisory
Committees on the results of the expert analyses and its own analyses of
the pediatric suicidality data.
