Newly added subsection:
5.10 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 ANJESO. 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
ANJESO and evaluate the patient immediately.

5.11 Fetal Toxicity
Premature Closure of Fetal Ductus Arteriosus
Avoid use of NSAIDs, including ANJESO, in pregnant
women at about 30 weeks gestation and later. NSAIDs, including
ANJESO, increase the risk of premature closure of the fetal ductus arteriosus
at approximately this gestational age.
Oligohydramnios/Neonatal Renal Impairment
Use of NSAIDs, including ANJESO, 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 ANJESO use to
the lowest effective dose and shortest duration possible. Consider ultrasound
monitoring of amniotic fluid if ANJESO treatment extends beyond 48 hours.
Discontinue ANJESO if oligohydramnios occurs and follow up according to
clinical practice
[see Use in Specific Populations (8.1)]

Risk Summary
Use of NSAIDs,
including ANJESO, 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
ANJESO use between about 20 and 30 weeks of gestation, and avoid ANJESO 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
ANJESO, 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 potential embryofetal risks of NSAID use in
women in the first or second trimesters of pregnancy are inconclusive.
In animal
reproduction studies, embryofetal death was observed in rats and rabbits
treated during the period of organogenesis with meloxicam at oral doses
equivalent to 0.32- and 3.24-times the maximum recommended human dose (MRHD) of
30 mg of ANJESO, based on body surface area (BSA) …
… 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
meloxicam, 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 ANJESO, 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 ANJESO treatment
extends beyond 48 hours, consider monitoring with ultrasound for
oligohydramnios. If oligohydramnios occurs, discontinue ANJESO 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.
