As the agency's review of the adverse event reports proceeds, it appears
increasingly likely that there may be an association between
Chantix and
serious neuropsychiatric symptoms.
As a result, FDA has requested that Pfizer, the manufacturer of Chantix,
elevate the prominence of this safety information to the warnings and
precautions section of the Chantix prescribing information, or labeling.

FDA ALERT [2/1/2008]: FDA is issuing this Alert to highlight important
revisions to the WARNINGS and PRECAUTIONS sections of the full prescribing
information for Chantix regarding serious neuropsychiatric symptoms.
Serious neuropsychiatric symptoms have occurred in patients taking Chantix.
These symptoms include changes in behavior, agitation, depressed mood,
suicidal ideation, and attempted and completed suicide.
While some patients may have experienced these types of symptoms and events
as a result of
nicotine withdrawal, some patients taking Chantix who
experienced serious neuropsychiatric symptoms and events had not yet
discontinued smoking. In most cases, neuropsychiatric symptoms developed
during Chantix treatment, but in others, symptoms developed following
withdrawal of Chantix therapy.
FDA first informed the public about the possibility of serious
neuropsychiatric symptoms in the November 20, 2007 FDA Early Communication
About an Ongoing Safety Review. At that time, information about serious
neuropsychiatric symptoms in patients taking Chantix was added to the
POST-MARKETING EXPERIENCE section of the prescribing information. As FDA's
review of the issue has progressed, it appears increasingly likely that
there is an association between Chantix and serious neuropsychiatric
symptoms.
As a result, FDA requested that Pfizer, the manufacturer of Chantix, elevate
the prominence of this safety information to the WARNINGS and PRECAUTIONS
sections of the Chantix prescribing information. In addition, FDA is working
with Pfizer to finalize a Medication Guide for patients.
