Seroxat Precautions
Activation of Mania/Hypomania:
Seroxat may trigger hypomania
or mania episodes in unipolar
and bipolar individuals. As
with all antidepressants,
Seroxat should be used
cautiously in patients with a
history of mania.
Suicide: The possibility of
a suicide attempt is inherent
in depression and may persist
until remission occurs.
Therefore, high risk patients
should be closely supervised
throughout therapy and
consideration should be given
to the possible need for
hospitalization. In order to
minimize the opportunity for
overdosage, prescriptions for
paroxetine should be written
for the smallest quantity of
drug consistent with good
patient management.
Seizures: Caution is
recommended when the drug is
administered to patients with
a history of seizures. The
drug should be discontinued in
any patient who develops
seizures.
Hyponatremia: Several cases
of hyponatremia have been
reported. The hyponatremia
appeared to be reversible when
Seroxat was discontinued. The
majority of these occurrences
have been in elderly
individuals, some in patients
taking diuretics or who were
otherwise volume depleted.

Abnormal Bleeding: There
have been several reports of
abnormal bleeding (mostly
ecchymosis and purpura)
associated with paroxetine
treatment, including a report
of impaired platelet
aggregation. While a causal
relationship to paroxetine is
unclear, impaired platelet
aggregation may result from
platelet serotonin depletion
and contribute to such
occurrences.
Use in Patients with
Concomitant Illness: Clinical
experience with Seroxat in
patients with certain
concomitant systemic illness
is limited. Caution is
advisable in using Seroxat in
patients with diseases or
conditions that could affect
metabolism or hemodynamic
responses.
Cardiac Conditions: Seroxat
has not been evaluated or used
to any appreciable extent in
patients with a recent history
of myocardial infarction or
unstable heart disease.
Clinical studies indicated
Seroxat (paroxetine
hydrochloride) does not cause
any clinically important
changes in heart rate or blood
pressure or any significant
ECG abnormalities.
Usage in Children: Do not
give to children under 18
years old.
Pregnancy & Nursing: The
effect of paroxetine on labor
and delivery in humans is
unknown. Therefore, Seroxat
should be used in women who
are or might become pregnant
only if the clinical condition
clearly justifies potential
risk to the fetus.
Like many other drugs,
paroxetine is secreted in
human milk, and caution should
be exercised when Seroxat (paroxetine
hydrochloride) is administered
to a nursing woman.

Interference with Cognitive
or Motor Performance: Any
psychoactive drug may impair
judgment, thinking or motor
skills. Although in controlled
studies Seroxat has not been
shown to impair psychomotor
performance, patients should
be cautioned about operating
hazardous machinery, including
automobiles, until they are
reasonably certain that
Seroxat therapy does not
affect their ability to engage
in such activities.
Seroxat Drug Interactions
Tryptophan: As with other
serotonin reuptake inhibitors,
an interaction between
paroxetine and tryptophan may
occur when they are
co-administered. Adverse
experiences, consisting
primarily of headache, nausea,
sweating and dizziness, have
been reported when tryptophan
was administered to patients
taking Seroxat (paroxetine
hydrochloride). Consequently,
concomitant use of Seroxat
with tryptophan is not
recommended.
Monoamine Oxidase
Inhibitors: Paroxetine should
not be used in combination
with MAO inhibitors or within
2 weeks of terminating
treatment with MAO inhibitors.
Treatment with paroxetine
should then be initiated
cautiously and dosage
increased gradually until
optimal response is reached.
MAO inhibitors should not be
introduced within 2 weeks of
cessation of therapy with
paroxetine.
Warfarin: Preliminary data
suggest that there may be a
pharmacodynamic interaction
(that causes an increased
bleeding diathesis in the face
of unaltered prothrombin time)
between paroxetine and
warfarin. Since there is
little clinical experience,
the concomitant administration
of Seroxat and warfarin should
be undertaken with caution.
Return to
top
Sumafriptan: There have
been rare postmarketing
reports describing patients
with weakness, hyperreflexia,
and incoordination following
the use of a selective
serotonin reuptake inhibitor (SSRI)
and sumatriptan. If
concomitant treatment with
sumatriptan and an SSRI (e.g.,
fluoxetine, fluvoxamine,
paroxetine, sertraline) is
clinically warranted,
appropriate observation of the
patient is advised.
Drugs Affecting Hepatic
Metabolism: The metabolism and
pharmacokinetics of paroxetine
may be affected by the
induction or inhibition of
drug-metabolizing enzymes.
Cimetidine, Phenobarbital,
Phenytoin.
Drugs Metabolized by
Cytochrome P450IID6: Many
drugs, including most
antidepressants (paroxetine,
other SSRls and many
tricyclics), are metabolized
by the cytochrome P450 isozyme
P45011D6. Concomitant use of
Seroxat with other drugs
metabolized by cytochrome
P45011D6 has not been formally
studied but may require lower
doses than usually prescribed
for either Seroxat or the
other drug.
Therefore,
co-administration of Seroxat
with other drugs that are
metabolized by this isozyme,
including certain
antidepressants (e.g.,
nortriptyline, amitriptyline,
imipramine, desipramine and
fluoxetine), phenothiazines
(e.g., thioridazine) and Type
iC antiarrhythmics (e.g.,
propafenone, flecainide and
encainide), or that inhibit
this enzyme (e.g., quinidine),
should be approached with
caution.
Tricyclic Antidepressants (TCA):
Caution is indicated in the
co-administration of tricyclic
antidepressants (TCAs) with
Seroxat, because paroxetine
may inhibit TCA metabolism.
Plasma TCA concentrations may
need to be monitored, and the
dose of TCA may need to be
reduced, if a TCA is
co-administered with Seroxat
(see above—Drugs Metabolized
by Cytochrome P45011D6).
Lithium, Digoxin, Diazapam:
Since there is little clinical
experience, the concurrent
administration of paroxetine
and the above drugs should be
undertaken with caution.

DO NOT DRINK ALCOHOL
while you are taking Seroxat.
Dependence & Withdrawl:
Seroxat (paroxetine
hydrochloride) is not a
controlled substance. Seroxat
has not been systematically
studied in animals or humans
for its potential for abuse,
tolerance or physical
dependence. While the clinical
trials did not reveal any
tendency for any drug-seeking
behavior, these observations
were not systematic and it is
not possible to predict on the
basis of this limited
experience the extent to which
a CNS-active drug will be
misused, diverted and/or
abused once marketed.
Consequently, patients should
be evaluated carefully for
history of drug abuse, and
such patients should be
observed closely for signs of
Seroxat misuse or abuse (e.g.,
development of tolerance,
incrementations of dose
drug-seeking behavior).

For Depression:
Adults: Usual Initial
Dosage: Seroxat (paroxetine
hydrochloride) should be
administered as a single daily
dose, usually in the morning.
The recommended initial dose
is 20 mg/day. Patients were
dosed in a range of 20 to 50
mg/day in the clinical trials
demonstrating the
antidepressant effectiveness
of Seroxat. As with all
antidepressants, the full
antidepressant effect may be
delayed. Some patients not
responding to a 20 mg dose may
benefit from dose increases,
in 10 mg/day increments, up to
a maximum of 50 mg/day. Dose
changes should occur at
intervals of at least 1 week.
Maintenance Therapy: There
is no body of evidence
available to answer the
question of how long the
patient treated with Seroxat
should remain on it. It is
generally agreed that acute
episodes of depression require
several months or longer of
sustained pharmacologic
therapy. Whether the dose of
an antidepressant needed to
induce remission is identical
to the dose needed to maintain
and/or sustain euthyrnia is
unknown. Systematic evaluation
of the efficacy of Seroxat (paroxetine
hydrochloride) has shown that
efficacy is maintained for
periods of up to 1 year with
doses that averaged about 30
mg.
Return to
top
For Obsessive-Compulsive
Disorder (OCD):
Adults: Seroxat (paroxetine
hydrochloride) should be
administered as a single daily
dose, usually in the morning.
The recommended dose of
Seroxat in the treatment of
OCD is 40 mg daily. Patients
should be started on 20 mg/day
and the dose can be increased
in 10 mg/day increments. Dose
changes should occur at
intervals of at least 1 week.
Patients were dosed in a range
of 20 to 60 mg/day in the
clinical trials demonstrating
the effectiveness of Seroxat
in the treatment of OCD.
Maintenance Therapy: It is
reasonable to consider
continuation for a responding
patient. Dosage adjustments
should be made to maintain the
patient on the lowest
effective dosage, and patients
should be periodically
reassessed to determine the
need for continued treatment.
For Panic Disorder:
Adults: Seroxat should be
administered as a single daily
dose, usually in the morning.
The target dose of Seroxat in
the treatment of panic
disorder is 40 mg/day.
Patients should be started on
10 mg/day. Dose changes should
occur in 10 mg/week increments
and at intervals of at least 1
week. Patients were dosed in a
range of 10 to 60 mg/day in
the clinical trials
demonstrating the
effectiveness of Seroxat. The
maximum dosage should not
exceed 60 mg/day.
Maintenance Therapy: Panic
disorder is a chronic
condition, and it is
reasonable to consider
continuation for a responding
patient. Dosage adjustments
should be made to maintain the
patient on the lowest
effective dosage, and patients
should be periodically
reassessed to determine the
need for continued treatment.
Elderly or Debilitated, and
Patients with Severe Renal or
Hepatic Impairment: The
recommended initial dose is 10
mg/ day for elderly patients,
debilitated patients, and/o(
patients with, severe renal or
hepatic impairment. Increases
may be made if indicated.
Dosage should not exceed 40
mg/day. Switching Patients to
or from a Monoamine Oxidese
Inhbitor: At least 14 days
should elapse between
discontinuation of a MACI and
initiation of Seroxat therapy.
Similarly, at least 14 days
should be allowed after
stopping Seroxat before
starting a MAOI.
Children under 18 years of
age: The use of paroxetine in
children under 18 years of age
is not recommended as safety
and efficacy have not been
established in this
population.
