Serious
Skin Reactions, Including DRESS
Advise
patients to stop VOLTAREN-XR immediately if they develop any type of rash or
fever and contact their healthcare provider as soon as possible (see
WARNINGS; Serious Skin Reactions).
Female
Fertility
Advise
females of reproductive potential who desire pregnancy that NSAIDs, including
VOLTAREN-XR, may be associated with a reversible delay in ovulation (see
PRECAUTIONS; Carcinogenesis, Mutagenesis, Impairment of Fertility).
Fetal
Toxicity
Inform
pregnant women to avoid use of VOLTAREN-XR and other NSAIDs, starting at 30-weeks’
gestation because of the risk of the premature closure of the fetal ductus
arteriosus. If treatment with VOLTAREN-XR 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.

Hepatotoxicity
In clinical trials of diclofenac- containing
products, meaningful elevations (i.e., more than 3 times the upper limit
of normal [ULN]) of aspartate aminotransferase (AST) (also known as SGOT)
were observed in about 2% of approximately 5700 patients at some time during
diclofenac treatment (ALT [alanine aminotransferase] was not measured in
all studies).

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

Risk Summary
Use of NSAIDs, including VOLTAREN-XR, 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 VOLTAREN-XR use between about 20 and
30 weeks of gestation, and avoid VOLTAREN-XR use at about 30 weeks of gestation
and later in pregnancy (see WARNINGS; Fetal Toxicity).
Premature Closure of Fetal Ductus Arteriosus
Use of NSAIDs, including VOLTAREN-XR, 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.
There
are no adequate and well-controlled studies of VOLTAREN-XR in pregnant women.
Data
from observational studies regarding potential embryo-fetal risks of
NSAID use in women in the first or second trimesters of pregnancy are
inconclusive.
In
animal reproduction studies, no evidence of teratogenicity was observed in
mice, rats, or rabbits given diclofenac daily during the period of
organogenesis at doses up to approximately 0.5, 0.5, and 1 times, respectively,
the maximum recommended human dose (MRHD) of VOLTAREN-XR, despite the presence
of maternal and fetal toxicity at these doses (see Data).
Based
on published 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 diclofenac, 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 VOLTAREN-XR, can cause premature closure of the fetal
ductus arteriosus (see WARNINGS; Fetal Toxicity).
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
VOLTAREN-XR treatment extends beyond 48 hours, consider monitoring with
ultrasound for oligohydramnios. If oligohydramnios occurs, discontinue
VOLTAREN-XR and follow up according to clinical practice (see WARNINGS; Fetal
Toxicity).
Labor or Delivery
There
are no studies on the effects of VOLTAREN-XR during labor or delivery. In
animal studies, NSAIDS, including diclofenac, inhibit prostaglandin synthesis,
cause delayed parturition, and increase the incidence of stillbirth.
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 post-marketing 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.
