PRECAUTIONS
Clinical Worsening And Suicide Risk
Patients with major depressive disorder (MDD), both adult
and pediatric, may experience worsening of their depression and/or the
emergence of suicidal ideation and behavior (suicidality) or unusual changes in
behavior, whether or not they are taking antidepressant medications, and this
risk may persist until significant remission occurs. Suicide is a known risk of
depression and certain other psychiatric disorders and these disorders
themselves are the strongest predictors of suicide. There has been a long
standing concern, however, that antidepressants may have a role in inducing
worsening of depression and the emergence of suicidality in certain patients
during the early phases of treatment. Pooled analyses of short-term
placebo-controlled trials of antidepressant drugs (SSRIs and others) showed
that these drugs increase the risk of suicidal thinking and behavior
(suicidality) in children, adolescents, and young adults (ages 18 – 24) with
MDD and other psychiatric disorders. Short-term studies did not show an
increase in the risk of suicidality with antidepressants compared to placebo in
adults beyond age 24; there was a reduction with antidepressants compared to
placebo in adults aged 65 and older.
The pooled analyses of placebo-controlled trials in
children and adolescents with MDD, obsessive compulsive disorder (OCD), or
other psychiatric disorders included a total of 24 short-term trials of 9
antidepressant drugs in over 4,400 patients. The pooled analyses of
placebo-controlled trials in adults with MDD or other psychiatric disorders
included a total of 295 short-term trials (median duration of 2 months) of 11
antidepressant drugs in over 77,000 patients. There was considerable variation
in risk of suicidality among drugs, but a tendency toward an increase in the
younger patients for almost all drugs studied. There were differences in
absolute risk of suicidality across the different indications, with the highest
incidence in MDD. The risk differences (drug vs. placebo), however, were
relatively stable within age strata and across indications. These risk
differences (drug-placebo difference in the number of cases of suicidality per
1,000 patients treated) are provided in Table 1.

No suicides occurred in any of
the pediatric trials. There were suicides in the adult trials, but the number
was not sufficient to reach any conclusion about drug effect on suicide.
It is unknown whether the
suicidality risk extends to longer-term use, i.e., beyond several months.
However, there is substantial evidence from placebo-controlled maintenance
trials in adults with depression that the use of antidepressants can delay the
recurrence of depression.
All patients being treated
with antidepressants for any indication should be monitored appropriately and
observed closely for clinical worsening, suicidality, and unusual changes in
behavior, especially during the initial few months of a course of drug therapy,
or at times of dose changes, either increases or decreases.
The following symptoms,
anxiety, agitation, panic attacks, insomnia, irritability, hostility,
aggressiveness, impulsivity, akathisia (psychomotor restlessness), hypomania,
and mania, have been reported in adult and pediatric patients being treated
with antidepressants for major depressive disorder as well as for other
indications, both psychiatric and nonpsychiatric. Although a causal link
between the emergence of such symptoms and either the worsening of depression
and/or the emergence of suicidal impulses has not been established, there is
concern that such symptoms may represent precursors to emerging suicidality.
Consideration should be given
to changing the therapeutic regimen, including possibly discontinuing the
medication, in patients whose depression is persistently worse, or who are
experiencing emergent suicidality or symptoms that might be precursors to
worsening depression or suicidality, especially if these symptoms are severe,
abrupt in onset, or were not part of the patient's presenting symptoms.
Families and caregivers of
patients being treated with antidepressants for major depressive disorder or
other indications, both psychiatric and nonpsychiatric, should be alerted about
the need to monitor patients for the emergence of agitation, irritability,
unusual changes in behavior, and the other symptoms described above, as well as
the emergence of suicidality, and to report such symptoms immediately to health
care providers. Such monitoring should
include daily observation by families and caregivers. Prescriptions for Oleptro should be written for the
smallest quantity of tablets consistent with good patient management, in order
to reduce the risk of overdose.
Serotonin Syndrome
The development of a
potentially life-threatening serotonin syndrome has been reported with SNRIs
and SSRIs, including Oleptro, alone but particularly with concomitant use of
other serotonergic drugs (including triptans, tricyclic antidepressants,
fentanyl, lithium, tramadol, tryptophan, busipirone, and St. John's Wort) and
with drugs that impair metabolism of serotonin (in particular, MAOIs, both
those intended to treat psychiatric disorders and also others, such as
linezolid and intravenous methylene blue).
Serotonin syndrome symptoms may
include mental status changes (e.g., agitation, hallucinations, delirium, and
coma), autonomic instability (e.g., tachycardia, labile blood pressure,
dizziness, diaphoresis, flushing, hyperthermia), neuromuscular symptoms (e.g.,
tremor, rigidity, myoclonus, hyperreflexia, incoordination), seizures, and/or
gastrointestinal symptoms (e.g., nausea, vomiting, diarrhea). Patients should
be monitored for the emergence of serotonin syndrome.
The concomitant use of Oleptro
with MAOIs intended to treat psychiatric disorders is contraindicated. Oleptro
should also not be started in a patient who is being treated with MAOIs such as
linezolid or intravenous methylene blue. All reports with methylene blue that
provided information on the route of administration involved intravenous
administration in the dose range of 1 mg/kg to 8 mg/kg. No reports involved
the administration of methylene blue by other routes (such as oral tablets or
local tissue injection) or at lower doses. There may be circumstances when it
is necessary to initiate treatment with an MAOI such as linezolid or
intravenous methylene blue in a patient taking Oleptro. Oleptro should be
discontinued before initiating treatment with the MAOI. [see CONTRAINDICATIONS
and DOSAGE AND ADMINISTRATION].
If concomitant use of Oleptro with other serotonergic
drugs, triptans, tricyclic antidepressants, fentanyl, lithium, tramadol,
buspirone, tryptophan and St. John's Wort is clinically warranted, patients
should be made aware of a potential increased risk for serotonin syndrome,
particularly during treatment initiation and dose increases.
Treatment with Oleptro and any concomitant serotonergic
agents, should be discontinued immediately if the above events occur and
supportive symptomatic treatment should be initiated.
Angle Closure Glaucoma
The pupillary dilation that occurs following use of many
antidepressant drugs including Oleptro may trigger an angle closure attack in a
patient with anatomically narrow angles who does not have a patent iridectomy.
Screening Patients For Bipolar Disorder And Monitoring For
Mania/Hypomania
A major depressive episode may be the initial
presentation of bipolar disorder. It is generally believed (though not
established in controlled trials) that treating such an episode with an
antidepressant alone may increase the likelihood of precipitation of a
mixed/manic episode in patients at risk for bipolar disorder. Whether any of
the symptoms described for clinical worsening and suicide risk represent such a
conversion is unknown. However, prior to initiating treatment with an
antidepressant, patients with depressive symptoms should be adequately screened
to determine if they are at risk for bipolar disorder; such screening should
include a detailed psychiatric history, including a family history of suicide,
bipolar disorder, and depression. It should be noted that Oleptro is not
approved for use in treating bipolar depression.
QT Prolongation And Risk Of Sudden Death
Trazodone is known to prolong the QT/QTc interval. Some
drugs that prolong the QT/QTc interval can cause Torsades de Pointes with
sudden, unexplained death. The relationship of QT prolongation is clearest for
larger increases (20 msec and greater), but it is possible that smaller QT/QTc
prolongations may also increase risk, especially in susceptible individuals,
such as those with hypokalemia, hypomagnesemia, or a genetic predisposition to
prolonged QT/QTc.
Although Torsades de Pointes has not been observed with
the use of Oleptro at recommended doses in premarketing trials, experience is
too limited to rule out an increased risk. However, there have been
postmarketing reports of Torsades de Pointes with the immediate-release form of
trazodone (in the presence of multiple confounding factors), even at doses of
100 mg per day or less.
Use In Patients With Heart Disease
Trazodone hydrochloride is not recommended for use during
the initial recovery phase of myocardial infarction.
Caution should be used when administering Oleptro to
patients with cardiac disease and such patients should be closely monitored,
since antidepressant drugs (including trazodone hydrochloride) may cause
cardiac arrhythmias.
QT prolongation has been reported with trazodone therapy [see QT Prolongation and Risk of Sudden Death]. Clinical studies in patients with
pre-existing cardiac disease indicate that trazodone hydrochloride may be
arrhythmogenic in some patients in that population. Arrhythmias identified
include isolated PVCs, ventricular couplets, tachycardia with syncope, and
Torsades de Pointes. Postmarketing events have been reported at doses of 100 mg
or less with the immediate-release form of trazodone.
Concomitant administration of drugs that prolong the QT
interval or that are inhibitors of CYP3A4 may increase the risk of cardiac
arrhythmia.
Orthostatic Hypotension And Syncope
Hypotension, including orthostatic hypotension and
syncope has been reported in patients receiving trazodone hydrochloride.
Concomitant use with an antihypertensive may require a reduction in the dose of
the antihypertensive drug.
Abnormal Bleeding
Postmarketing data have shown an association between use
of drugs that interfere with serotonin reuptake and the occurrence of
gastrointestinal (GI) bleeding. While no association between trazodone and
bleeding events, in particular GI bleeding, was shown, patients should be
cautioned about potential risk of bleeding associated with the concomitant use
of trazodone and NSAIDs, aspirin, or other drugs that affect coagulation or
bleeding. Other bleeding events related to SSRIs and SNRIs have ranged from
ecchymosis, hematoma, epistaxis, and petechiae to life-threatening hemorrhages.
Interaction With MAOIs
In patients receiving serotonergic drugs in combination
with a monoamine oxidase inhibitor (MAOI), there have been reports of serious,
sometimes fatal reactions including hyperthermia, rigidity, myoclonus,
autonomic instability with rapid fluctuation in vital signs, and mental status
changes that include extreme agitation progressing to delirium and coma. These
reactions have also been reported in patients who have recently discontinued
antidepressant treatment and have been started on an MAOI. Some cases presented
with features resembling neuroleptic malignant syndrome. Furthermore, limited
animal data on the effects of combined use of serotonergic antidepressants and
MAOIs suggest that these drugs may act synergistically to elevate blood pressure
and evoke behavioral excitation. Therefore, it is recommended that Oleptro
should not be used in combination with an MAOI or within 14 days of
discontinuing treatment with an MAOI. Similarly, at least 14 days should be
allowed after stopping Oleptro before starting an MAOI.
Priapism
Rare cases of priapism (painful erections greater than 6
hours in duration) were reported in men receiving trazodone. Priapism, if not
treated promptly, can result in irreversible damage to the erectile tissue. Men
who have an erection lasting greater than 6 hours, whether painful or not,
should immediately discontinue the drug and seek emergency medical attention [see
ADVERSE REACTIONS and OVERDOSAGE].
Trazodone should be used with caution in men who have
conditions that might predispose them to priapism (e.g., sickle cell anemia,
multiple myeloma, or leukemia), or in men with anatomical deformation of the
penis (e.g., angulation, cavernosal fibrosis, or Peyronie's disease).
Hyponatremia
Hyponatremia may occur as a result of treatment with
antidepressants. In many cases, this hyponatremia appears to be the result of
the syndrome of inappropriate antidiuretic hormone secretion (SIADH). Cases
with serum sodium lower than 110 mmol/L have been reported. Elderly patients
may be at greater risk of developing hyponatremia with antidepressants. Also,
patients taking diuretics or who are otherwise volume-depleted can be at
greater risk. Discontinuation of Oleptro should be considered in patients with
symptomatic hyponatremia and appropriate medical intervention should be
instituted.
Signs and symptoms of hyponatremia include headache,
difficulty concentrating, memory impairment, confusion, weakness, and
unsteadiness, which can lead to falls. Signs and symptoms associated with more
severe and/or acute cases have included hallucination, syncope, seizure, coma,
respiratory arrest, and death.
Potential For Cognitive And Motor Impairment
Oleptro may cause somnolence or sedation and may impair
the mental and/or physical ability required for the performance of potentially
hazardous tasks. Patients should be cautioned about operating hazardous
machinery, including automobiles, until they are reasonably certain that the
drug treatment does not affect them adversely.
Discontinuation Symptoms
Withdrawal symptoms including anxiety, agitation and
sleep disturbances, have been reported with trazodone. Clinical experience
suggests that the dose should be gradually reduced before complete
discontinuation of the treatment.
Patient Counseling Information
See Medication
Guide.
Information For Patients
Prescribers or other health professionals should inform
patients, their families, and their caregivers about the benefits and risks
associated with treatment with Oleptro and should counsel them in its
appropriate use.
Patients Should Be Warned That
- There is a potential for increased risk of suicidal
thoughts especially in children, teenagers and young adults.
- The following symptoms should be reported to the
physician: anxiety, agitation, panic attacks, insomnia, irritability,
hostility, aggressiveness, impulsivity, akathisia, hypomania and mania.
- They should inform their physician if they have a history
of bipolar disorder, cardiac disease or myocardial infarction.
- Serotonin syndrome could occur and symptoms may include
changes in mental status (e.g., agitation, hallucinations, and coma), autonomic
instability (e.g., tachycardia, labile blood pressure, and hyperthermia),
neuromuscular aberrations (e.g., hyperreflexia, incoordination) and/or gastrointestinal
symptoms (e.g., nausea, vomiting, and diarrhea).
- Patients should be advised that taking Oleptro can cause
mild pupillary dilation, which in susceptible individuals, can lead to an
episode of angle closure glaucoma. Pre-existing glaucoma is almost always
open-angle glaucoma because angle closure glaucoma, when diagnosed, can be
treated definitively with iridectomy. Open-angle glaucoma is not a risk factor
for angle closure glaucoma. Patients may wish to be examined to determine
whether they are susceptible to angle closure, and have a prophylactic
procedure (e.g., iridectomy), if they are susceptible. [see WARNINGS AND
PRECAUTIONS]
- Trazodone hydrochloride has been associated with the
occurrence of priapism.
- There is a potential for hypotension, including
orthostatic hypotension and syncope.
- There is a potential risk of bleeding (including
life-threatening hemorrhages) and bleeding related events (including
ecchymosis, hematoma, epistaxis, and petechiae) with the concomitant use of
trazodone hydrochloride and NSAIDs, aspirin, or other drugs that affect
coagulation or bleeding.
- Withdrawal symptoms including anxiety, agitation and
sleep disturbances, have been reported with trazodone. Clinical experience
suggests that the dose should be gradually reduced.
Patients Should Be Counseled That
- Oleptro may cause somnolence or sedation and may impair
the mental and/or physical ability required for the performance of potentially
hazardous tasks. Patients should be cautioned about operating hazardous
machinery, including automobiles until they are reasonably certain that the
drug treatment does not affect them.
- Trazodone may enhance the response to alcohol,
barbiturates, and other CNS depressants.
- Women who intend to become pregnant or who are
breastfeeding should discuss with a physician whether they should continue to
use Oleptro, since use in pregnant and nursing women is not recommended.
Important Administration Instructions
- Oleptro should be swallowed whole or broken in half along
the score line.
- In order to maintain its controlled-release properties,
it should not be chewed or crushed.
- Oleptro should be taken at the same time every day, in
the late evening preferably at bedtime, on an empty stomach.
Nonclinical Toxicology
Carcinogenesis, Mutagenesis, Impairment Of Fertility
No drug- or dose-related occurrence of carcinogenesis was
evident in rats receiving trazodone in daily oral doses up to 300 mg/kg for 18
months.
Use In Specific Populations
Pregnancy
Pregnancy Category C
Trazodone hydrochloride has been shown to cause increased
fetal resorption and other adverse effects on the fetus in two studies using
the rat when given at dose levels approximately 30 – 50 times the proposed
maximum human dose. There was also an increase in congenital anomalies in one
of three rabbit studies at approximately 15 – 50 times the maximum human dose.
There are no adequate and well-controlled studies in pregnant women. Oleptro
should be used during pregnancy only if the potential benefit justifies the
potential risk to the fetus.
Nursing Mothers
Trazodone and/or its metabolites have been found in the
milk of lactating rats, suggesting that the drug may be secreted in human milk.
Caution should be exercised when Oleptro is administered to a nursing woman.
Pediatric Use
Safety and effectiveness in the pediatric population have
not been established [see BOXED WARNING and WARNINGS AND PRECAUTIONS
]. Oleptro should not be used in children or adolescents.
Geriatric Use
Of 202 patients treated with Oleptro in the clinical
trial, there were 9 patients older than 65. No overall differences in safety or
effectiveness were observed between these subjects and younger subjects, and
other reported clinical literature and experience with trazodone have not
identified differences in responses between elderly and younger patients.
However, as experience in the elderly with Oleptro is limited, it should be
used with caution in geriatric patients.
Antidepressants have been associated with cases of
clinically significant hyponatremia in elderly patients who may be at greater
risk for this adverse reaction [see WARNINGS AND PRECAUTIONS.]
Renal Impairment
Oleptro has not been studied in patients with renal
impairment. Trazodone should be used with caution in this population.
Hepatic Impairment
Oleptro has not been studied in patients with hepatic
impairment. Trazodone should be used with caution in this population.
