FDA
ALERT [6/16/2008]: FDA is notifying healthcare professionals that both
conventional and atypical antipsychotics are associated with an
increased risk of mortality in elderly patients treated for
dementia-related psychosis.
In
April 2005, FDA notified healthcare professionals that patients with
dementia-related psychosis treated with atypical antipsychotic drugs
are at an increased risk of death. Since issuing that notification,
FDA has reviewed additional information that indicates the risk is also
associated with conventional antipsychotics.
Antipsychotics are not indicated for the treatment of dementia-related psychosis.
This
information reflects FDA's current analysis of data available to FDA
concerning these drugs. FDA intends to update this sheet when
additional information or analyses become available.
To
report any unexpected adverse or serious events associated with the use
of these drugs, please contact the FDA MedWatch program and complete a
form on line at http://www.fda.gov/medwatch/report/hcp.htm
or report by fax to 1-800-FDA-0178, by mail using the postage-paid
address form provided on line, or by telephone to 1-800-FDA-1088.
FDA is requiring the manufacturers of conventional antipsychotic drugs to add a Boxed Warning and Warning to
the drugs' prescribing information about the risk of mortality in
elderly patients treated for dementia-related psychosis similar to the Boxed Warning and Warning added to the prescribing information of the atypical antipsychotic drugs in 2005.* See the last page of this document for a list of conventional and atypical antipsychotic drugs.
Considerations for Healthcare Professionals
- Elderly
patients with dementia-related psychosis treated with conventional or
atypical antipsychotic drugs are at an increased risk of death.
- Antipsychotic drugs are not approved for the treatment of dementia-related psychosis. Furthermore,
there is no approved drug for the treatment of dementia-related
psychosis. Healthcare professionals should consider other management
options.
- Physicians
who prescribe antipsychotics to elderly patients with dementia-related
psychosis should discuss this risk of increased mortality with their
patients, patients' families, and caregivers.
Background Information and Data
Previously,
in April 2005, FDA informed healthcare professionals and the public
about the increased risk of mortality in elderly patients receiving
atypical antipsychotic drugs to treat dementia-related psychosis (April 2005 Public Health Advisory and Information for Healthcare Professionals).
At that time, the analyses of 17 placebo-controlled trials that
enrolled 5377 elderly patients with dementia-related behavioral
disorders revealed a risk of death in the drug-treated patients of
between 1.6 to 1.7 times that seen in placebo-treated patients.
Although the causes of death were varied, most of the deaths appeared
to be either cardiovascular (e.g., heart failure, sudden death) or
infectious (e.g. pneumonia) in nature. Based on this analysis, FDA
requested that the manufacturers of atypical antipsychotic drugs
include information about this risk in a Boxed Warning and the Warnings section of the drugs' prescribing information.
Recently, two observational epidemiological studies1,2 were published that examined the risk of death in patients who were treated with conventional antipsychotic drugs.
Gill et al.1
performed a retrospective cohort study in Ontario, Canada of 27,259
adults, 66 years of age or older, with a diagnosis of dementia between
April 1997 and March 2002. The investigators compared the risk for
death with use of an atypical antipsychotic versus no antipsychotic and
the risk for death with use of a conventional antipsychotic versus an
atypical antipsychotic. They found that atypical antipsychotics were
associated with increased mortality as compared to no antipsychotic use
as early as 30 days and persisting until study end at 180 days. The
investigators found that conventional antipsychotic use showed a
marginally higher risk of death compared with atypical antipsychotic
use. The causes of death were not reported in this study.
Schneeweiss et al.2
performed a retrospective cohort study in British Columbia, Canada of
37,241 adults, 65 years of age or older, who were prescribed
conventional (12,882) or atypical (24,359) antipsychotic medications
for any reason between January 1996 and December 2004. The
investigators compared the 180-day all cause mortality with use of a
conventional antipsychotic versus an atypical antipsychotic. They found
that the risk of death in the group of patients treated with
conventional antipsychotic medications was comparable to, or possibly
greater than, the risk of death in the group of patients treated with
atypical antipsychotic medications. The causes of death with the
highest relative risk were cancer and cardiac disease.
FDA
considers that the methodological limitations in these two studies
preclude any conclusion that conventional antipsychotics have a
greater risk of death with use than atypical antipsychotics. FDA has
determined, however, that the overall weight of evidence, including
these studies, indicates that the conventional antipsychotics share the
increased risk of death in elderly patients with dementia-related
psychosis that has been observed for the atypical antipsychotics. The
prescribing information for all antipsychotic drugs will now include
the same information about this risk in a Boxed Warning and the Warnings section.
