- What is FDA announcing regarding the use of antidepressants?
FDA is announcing a request to the manufacturers of ten
antidepressant drugs that they strengthen the "Warnings"
section of the package insert to encourage close observation for
worsening depression or the emergence of suicidal thinking and
behavior in both adult and pediatric patients being treated with
these agents, particularly for depression but also for other
psychiatric and nonpsychiatric disorders. Although a causal role
for antidepressants in inducing such behaviors has not been
established, careful monitoring of patients needing treatment with
these medications is important, and discontinuation of medication
may be appropriate in patients whose depression is persistently
worse or whose emergent suicidality is severe, abrupt in onset, or
was not part of the patient’s presenting symptoms.
The proposed new Warning also alerts
prescribers, patients, and their caregivers to the emergence of
certain symptoms that are known to be associated with
antidepressants in some patients, in particular, anxiety,
agitation, panic attacks, insomnia, irritability, hostility,
impulsivity, akathisia (severe restlessness), hypomania, and
mania. Although a causal link has not been established between the
emergence of such symptoms and either worsening of depression or
the emergence of suicidal impulses, medications may need to be
discontinued when such symptoms are severe, abrupt in onset, or
were not part of the patient’s presenting symptoms.
- Why is FDA making this announcement now?
The Psychopharmacological Drugs Advisory Committee (PDAC) and
the Pediatric Subcommittee of the Anti-Infective Drugs Advisory
Committee held an advisory committee meeting on February 2, 2004,
to discuss reports of the occurrence of suicidality in clinical
trials for various antidepressant drugs in pediatric patients with
major depressive disorder. These reports remain under review and
we have not concluded that the antidepressants cause suicidal
thinking or behavior. The committees recommended that, even before
FDA’s analysis of the controlled trials is completed, it would
be useful to strengthen the labeling for these products by drawing
more attention to the need for close monitoring of patients
(adults, children and adolescents) being treated with
antidepressants.
- What products are involved in this announcement of a labeling
change?
The drugs that are the focus of this labeling change are:
Prozac (fluoxetine), Zoloft (sertraline), Paxil (paroxetine),
Luvox (fluvoxamine), Celexa (citalopram); Lexapro (escitalopram),
Wellbutrin (bupropion), Effexor (venlafaxine), Serzone (nefazodone),
and Remeron (mirtazapine).
- Are the drugs mentioned above approved for use in children and
adolescents?
Prozac (fluoxetine) is approved for use in children and
adolescents for the treatment of major depressive disorder. Prozac
(fluoxetine), Zoloft (sertraline), and Luvox (fluvoxamine) are
approved for use in children and adolescents for the treatment of
obsessive compulsive disorder. The other drugs have no approved
uses in children.
- I am currently taking an antidepressant. What should I do?
You should consult your doctor to discuss the best course of
action if you observe worsening depression, the emergence of
suicidal thinking, or if you are experiencing other symptoms
mentioned under #1 above that you are concerned might be related
to taking your medication. It is very important that you do not
stop taking your antidepressant without first checking with your
doctor. Also, some of these medications may be associated
with discontinuation symptoms if stopped abruptly. If your doctor
advises that your medication should be stopped, be sure to follow
your doctor’s advice about how to accomplish this.
- My child or adolescent, or someone else I am caring for, is
currently taking an antidepressant. What should I do?
You should consult the doctor responsible for your child’s or
this person’s medications to discuss the best course of action
if you observe worsening depression, the emergence of suicidal
thinking, or if you observe other symptoms mentioned under #1
above that you are concerned might be related to taking
medication. It is very important that you do not
stop your child’s or this person’s antidepressant without
first checking with the prescribing doctor. Also, some of
these medications may be associated with discontinuation symptoms
if stopped abruptly, so that, if the doctor advises that the
medication should be stopped, be sure to follow the doctor’s
advice about how to accomplish this.
- When will FDA’s review of the data be completed?
Later this summer, the FDA plans to hold a public meeting to
update the Psychopharmacological Drugs Advisory Committee (PDAC)
and the Pediatric Subcommittee of the Anti-Infective Drugs
Advisory Committee of the results of the re-analyses of the
pediatric suicidality data to seek their expert input.
