Special Alerts:
[Posted 06/16/2008] FDA notified 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. The prescribing information for all antipsychotic drugs will now include the same information about this risk in a BOXED WARNING and the WARNINGS section. For more information visit the FDA website at: http://www.fda.gov/medwatch/safety/2008/safety08.htm#Antipsychotics, http://www.fda.gov/cder/drug/InfoSheets/HCP/antipsychotics_conventional.htm and http://www.fda.gov/bbs/topics/NEWS/2008/NEW01851.html.
[Posted 09/17/2007] Johnson and Johnson and FDA informed healthcare professionals that the WARNINGS section of the prescribing information for haloperidol has been revised to include a new Cardiovascular subsection regarding cases of sudden death, QT prolongation and Torsades de Pointes(TdP) in patients treated with haloperidol, especially when given intravenously, or at doses higher than recommended. Although injectable haloperidol is only approved by the FDA for intramuscular injection, there is considerable evidence that the intravenous administration of haloperidol is a relatively common off-label clinical practice.
There are at least 28 case reports of QT prolongation and TdP, some with fatal outcome in the context of off-label intravenous haloperidol. Healthcare professionals should consider this new risk information when making individual treatment decisions for their patients. For more information visit the FDA website at: http://www.fda.gov/medwatch/safety/2007/safety07.htm#Haloperidol and http://www.fda.gov/cder/drug/InfoSheets/HCP/haloperidol.htm.
