Serious Skin Reactions, including
DRESS
Advise
patients to stop taking EQUAGESIC immediately if they
develop any type of rash or fever and to contact
their healthcare provider
as soon as possible [see
WARNINGS].
Pregnancy
Embryo-Fetal Toxicity
Inform pregnant women to
avoid use of aspirin and other NSAIDs starting
at 30 weeks gestation because of the
risk of the premature closing
of the
fetal ductus arteriosus. If treatment
with EQUAGESIC is needed for
a pregnant woman between about 20 to 30 weeks gestation,
advise her that she may need to be monitored for oligohydramnios, if treatment continues for longer than 48 hours
[see
WARNINGS; Fetal Toxicity, PRECAUTIONS; Pregnancy].

Fetal Toxicity
Premature Closure of Fetal
Ductus Arteriosus
Avoid
use of NSAIDs, including EQUAGESIC, in pregnant women at about 30 weeks gestation
and later. NSAIDs, including
EQUAGESIC, increase the risk of premature
closure of the fetal ductus
arteriosus at approximately this gestational age.
Oligohydramnios/Neonatal Renal
Impairment
Use of NSAIDs, including EQUAGESIC, at about
20 weeks gestation or later in pregnancy may cause fetal renal
dysfunction leading to oligohydramnios and, in some
cases, neonatal renal impairment. These adverse outcomes
are seen, on average,
after days to weeks of treatment, although oligohydramnios has been infrequently reported as soon as 48 hours after NSAID initiation. Oligohydramnios is often,
but not always, reversible with
treatment discontinuation. Complications of prolonged oligohydramnios
may, for example, include limb contractures
and delayed lung maturation. In some postmarketing cases of impaired neonatal renal
function, invasive procedures such as exchange transfusion or dialysis were required.
If NSAID treatment is necessary between about 20 weeks and 30 weeks gestation, limit EQUAGESIC use to the lowest effective
dose and shortest duration possible.
Consider ultrasound monitoring of amniotic fluid if EQUAGESIC
treatment extends beyond 48
hours. Discontinue EQUAGESIC
if oligohydramnios occurs and follow up according
to clinical practice [see PRECAUTIONS; Pregnancy].
Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS)
Drug Reaction with Eosinophilia
and Systemic
Symptoms (DRESS) has been reported
in patients taking NSAIDs
such as EQUAGESIC. Some of these
events have been fatal or
life-threatening. DRESS
typically, although not exclusively, presents
with fever, rash, lymphadenopathy, and/or facial
swelling. Other clinical
manifestations may include
hepatitis, nephritis, hematological abnormalities,
myocarditis, or myositis. Sometimes symptoms of
DRESS may resemble an acute viral
infection. Eosinophilia is often present. Because
this disorder is variable in
its presentation, other organ systems not noted here may be involved. It is important to note that
early manifestations of hypersensitivity, such as fever or lymphadenopathy,
may be present even though rash is not
evident. If such signs or symptoms are present, discontinue EQUAGESIC and evaluate the patient immediately.

Risk Summary
Use of NSAIDs, including EQUAGESIC, can cause premature closure of the fetal ductus arteriosus and fetal
renal dysfunction leading to oligohydramnios
and, in some cases, neonatal renal impairment. Because
of these risks, limit dose and
duration of EQUAGESIC use between about 20 and
30 weeks of gestation, and avoid EQUAGESIC use at about 30 weeks of gestation and later in pregnancy (see Clinical Considerations, Data).
Premature Closure of Fetal Ductus Arteriosus
Use of NSAIDs, including EQUAGESIC, at about
30 weeks gestation or later in pregnancy increases the risk of premature closure of the fetal ductus arteriosus.
Oligohydramnios/Neonatal Renal
Impairment
Use of NSAIDs at
about 20 weeks gestation or later in pregnancy has been associated with cases of fetal renal
dysfunction leading to oligohydramnios,
and in some cases, neonatal renal
impairment.
Data from observational studies regarding other potential embryofetal
risks of NSAID use in women
in the first or second trimesters of pregnancy are inconclusive.
Based on animal data, prostaglandins
have been shown to have an important
role in endometrial vascular permeability, blastocyst
implantation, and decidualization. In animal studies, administration
of prostaglandin synthesis
inhibitors such as aspirin, resulted
in increased
pre- and post-implantation loss.
Prostaglandins
also have been shown to have an important role in fetal
kidney development. In published animal studies,
prostaglandin synthesis inhibitors have been reported to impair kidney development when administered
at clinically relevant
doses.
The estimated background risk of major birth defects and miscarriage for the indicated
population(s) is unknown. All
pregnancies have a background
risk of birth defect, loss,
or other adverse outcomes. In the
U.S. general population, the estimated
background risk of major birth defects
and miscarriage
in clinically recognized pregnancies
is 2% to 4% and 15% to 20%, respectively.
Clinical Considerations
Fetal/Neonatal Adverse Reactions
Premature Closure of
Fetal Ductus Arteriosus:
Avoid use of NSAIDs
in women at about 30 weeks gestation
and later in pregnancy, because NSAIDs, including EQUAGESIC, can cause premature closure of the fetal ductus
arteriosus (see Data).
Oligohydramnios/Neonatal
Renal Impairment:
If an NSAID is necessary at
about 20 weeks gestation or later in pregnancy, limit the use to the lowest effective
dose and shortest duration possible.
If EQUAGESIC treatment extends beyond 48 hours, consider monitoring with ultrasound for oligohydramnios. If oligohydramnios occurs, discontinue EQUAGESIC and follow up according to clinical
practice (see Data).
Data
Human Data
Premature Closure of
Fetal Ductus Arteriosus:
Published literature reports that the use of NSAIDs
at about 30 weeks of gestation and later
in pregnancy may cause premature closure of the fetal
ductus arteriosus.
Oligohydramnios/Neonatal
Renal Impairment:
Published studies and
postmarketing reports describe maternal NSAID use at about 20 weeks gestation
or later in pregnancy associated with fetal renal
dysfunction leading to oligohydramnios, and in some cases, neonatal renal impairment. These adverse outcomes
are seen, on average, after days to weeks
of treatment, although oligohydramnios
has been infrequently reported
as soon as 48 hours after NSAID
initiation. In many cases, but not all, the decrease
in amniotic
fluid was transient
and reversible with cessation
of the drug. There have been a limited number of case reports
of maternal
NSAID use and neonatal renal
dysfunction without oligohydramnios, some of
which were irreversible. Some cases of neonatal
renal dysfunction required treatment with invasive procedures, such as exchange
transfusion or dialysis.
Methodological limitations of these
postmarketing studies and reports
include lack of a control
group; limited information regarding dose, duration, and timing of drug exposure;
and concomitant use of other medications. These limitations preclude establishing
a reliable estimate of the risk
of adverse fetal and neonatal outcomes with maternal NSAID use. Because the published
safety data on neonatal outcomes
involved mostly preterm infants,
the generalizability of certain
reported risks to
the full-term infant exposed to NSAIDs through maternal use
is uncertain.
