Trials Experience
Additions and/or
revisions underlined:
Because clinical trials are conducted under widely
varying conditions, adverse reaction rates observed in the clinical trials of a
drug cannot be directly compared with rates in the clinical trials of another
drug and may not reflect the rates observed in practice.
Adult Clinical Trials
Experience
A
total of 874 subjects were exposed to one or more doses of LICART in eleven
clinical studies, including approximately 500 subjects who were treated with
LICART in six controlled multiple-dose trials. Approximately 400 of these were
exposed to the once-a-day 24-hour application, for up to one week in 288
subjects and up to two weeks in 121 subjects.

Pediatric Clinical
Trials Experience
In one open-label trial,
101 male and female pediatric patients 6 to 16 years
old and 50 adult patients
presenting with minor sprains,
strains, and contusions received LICART once daily for a mean duration of 12 days (range
2 to 25 days). The adverse reactions
reported in the pediatric study
population were application site erythema (1%),
appetite disorder (1%), and pollakiuria (1%).
6.2 Postmarketing
Experience
Additions and/or
revisions underlined:
The following adverse reactions
have been identified during post-approval use of LICART or other diclofenac
topical system products. Because these reactions are reported voluntarily from a population of uncertain size, it
is not always possible to reliably estimate
their frequency or establish a causal relationship to drug exposure.

Cases suggesting dermal allergic reactions
and photoallergic reactions

Use in Specific Populations
8.4 Pediatric Use
Additions and/or
revisions underlined:
The
safety and effectiveness of LICART for the topical treatment of acute pain due
to minor strains, sprains, and contusions have been established in pediatric
patients 6 years and older. Use of LICART for this indication is supported by
evidence from adequate and well-controlled studies with LICART in adults, as
well as an open-label study in 101 pediatric patients
6 years and older. One LICART was applied daily
to the injury site until pain
resolved or for a maximum of 14 days, whichever occurred first. Based on the available data from the pediatric study, the safety profile of
LICART topical system in pediatric patients is similar to that in adults. The
safety and effectiveness of LICART have not been investigated in pediatric
patients less than 6 years old. [see Clinical Trials Experience (6.1), Clinical
Pharmacology (12.3)].

Warnings and Precautions
5.9 Serious Skin Reactions
Additions and/or
revisions underlined:
NSAIDs, including diclofenac, can cause serious
skin adverse reactions such as exfoliative dermatitis, Stevens-Johnson Syndrome
(SJS), and toxic epidermal necrolysis (TEN), which can be fatal. NSAIDs can
also cause fixed drug eruption (FDE). FDE may present as a more severe variant
known as generalized bullous fixed drug eruption (GBFDE),
which can be life-threatening. These serious
events may occur without warning. Inform patients about the signs and symptoms
of serious skin reactions, and to discontinue the use of LICART at the first
appearance of skin rash or any other sign of hypersensitivity.
LICART is contraindicated in patients with previous
serious skin reactions to NSAIDs [see Contraindications (4)].

Warnings and Precautions
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 LICART. 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 LICART and evaluate
the patient immediately.

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

Risk Summary
Use of NSAIDs,
including LICART, 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
LICART use between about 20 and 30 weeks of gestation, and avoid LICART use at
about 30 weeks of gestation and later in pregnancy (see Clinical Considerations and Data).
Premature
Closure of Fetal Ductus Arteriosus
Use of NSAIDs,
including LICART, 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.
In animal
reproduction studies, diclofenac epolamine administered orally to pregnant rats
and rabbits during the period of organogenesis produced embryotoxicity at
approximately 3 and 7 times, respectively, the topical exposure from the
maximum recommended human dose (MRHD) of LICART … 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 …
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 LICART, 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 LICART treatment
extends beyond 48 hours, consider monitoring with ultrasound for
oligohydramnios. If oligohydramnios occurs, discontinue LICART 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.

MEDICATION GUIDE
Additions and/or
revisions underlined:
Before
taking NSAIDS, tell your healthcare provider about all of your medical
conditions, including if you:
are pregnant or
plan to become pregnant. Taking NSAIDs at about 20 weeks of pregnancy or
later may harm your unborn baby. If you need to take NSAIDs for more than 2
days when you are between 20 and 30 weeks of pregnancy, your healthcare
provider may need to monitor the amount of fluid in your womb around your baby.
You should not take NSAIDs after about 30 weeks of pregnancy.
PATIENT COUNSELING INFORMATION
Additions
and/or revisions underlined:
Serious Skin Reactions, including DRESS
Advise patients to stop using LICART immediately if they develop
any type of rash or fever and to contact their healthcare provider as
soon as possible [see Warnings and Precautions (5.9, 5.10)].
Fetal Toxicity
Inform pregnant women to avoid use of LICART and other
NSAIDs starting at 30 weeks’ gestation because of the risk of the premature
closure of the fetal ductus arteriosus. If treatment with LICART 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 and Precautions (5.11) and
Use in Specific Populations (8.1)].
