5.1 Endocrine
Systems Adverse Reactions

Additions and/or
revisions underlined:
Hypothalamic-Pituitary-Adrenal (HPA) Axis
Suppression
. . .
Cushing’s Syndrome, Hyperglycemia, and Glucosuria
Systemic effects of topical corticosteroids,
including ELOCON cream, may also manifest as Cushing’s syndrome, hyperglycemia,
and glucosuria.
Additional Considerations
Concomitant use of ELOCON cream with other
corticosteroid-containing products may increase total systemic corticosteroid
exposure, and result in increased risk for adverse reactions.
Pediatric patients may be more susceptible to
systemic toxicity from equivalent doses due to their larger skin surface to
body mass ratios [see Use in Specific Populations (8.4)].
Minimize the risk of adverse reactions by using
ELOCON cream as recommended [see Dosage and Administration (2)].
5.3 Allergic
Contact Dermatitis
Additions and/or
revisions underlined:
Use
of topical corticosteroids, including ELOCON cream, can cause allergic contact
dermatitis. Allergic
contact dermatitis with corticosteroids is usually diagnosed by observing a
failure to heal rather than noting a clinical exacerbation. Corroborate such an
observation with appropriate diagnostic patch testing. If allergic contact
dermatitis develops, discontinue ELOCON cream and institute appropriate therapy.
5.4 Concomitant
Skin Infections
Additions and/or
revisions underlined:
Use of topical corticosteroids, including ELOCON
cream, may delay healing or worsen concomitant skin infections.
If concomitant skin infections are present or develop,
treat with an
appropriate antimicrobial agent. If a favorable response does not occur
promptly,
gradually withdraw ELOCON cream and discontinue use until the
infection has been adequately controlled.

Risk Summary
There are no adequate and well-controlled studies in
pregnant women. Available data from postmarketing reports and published
observational studies over decades of use with mometasone furoate use during
pregnancy have not identified a drug-associated risk of major birth defects, miscarriage, or
adverse maternal outcomes. Maternal use of potent or very potent topical
corticosteroids may be associated with an
increased risk of low birth weight infants (see
Data). Advise pregnant women to use ELOCON cream on the smallest area of
skin and for the shortest duration possible.
When administered subcutaneously, orally, or
topically to pregnant rats, rabbits, and mice, mometasone furoate increased
fetal malformations. The doses that produced malformations also decreased fetal
growth, as measured by lower fetal weights and/or delayed ossification.
Mometasone furoate also caused dystocia and related complications when
administered to rats during the end of pregnancy (see Data). The available data do not allow the
calculation of relevant comparisons between the systemic exposure of mometasone
furoate observed in animal studies to the systemic exposure that would be
expected in humans after topical use of ELOCON cream.
The background risk of major birth defects and
miscarriage for the indicated population is unknown. All pregnancies have a
background risk of birth defect, loss, or other adverse outcomes. In the U.S.
general population, the estimated risk of major birth defects and miscarriage
in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively.
Data
Human Data
Published data from one observational study that
included 60,497 pregnancies exposed to topical corticosteroids, including
10,056 pregnancies exposed to topical mometasone, did not identify an increased
risk of low birth weight infants. However, data from other observational
studies demonstrate that maternal use of potent to very potent topical
corticosteroids was associated with an increased risk of low birth weight
infants, especially when the cumulative dosage throughout pregnancy was greater
than 300 grams. Available studies have limitations including confounding by
disease severity, imprecision in birth weight outcomes, and data reliance on
filled prescriptions rather than actual use.
Animal Data
In mice, mometasone furoate caused cleft palate at
subcutaneous doses of 60 mcg/kg and above.
Fetal survival was reduced at 180 mcg/kg. No
toxicity was observed at 20 mcg/kg.
In rats, mometasone furoate produced umbilical
hernias at topical doses of 600 mcg/kg and above.
Mometasone furoate produced
delays in ossification, but no malformations at 300 mcg/kg.
In rabbits, mometasone furoate caused multiple
malformations (e.g., flexed front paws, gallbladder agenesis, umbilical hernia,
hydrocephaly) at topical doses of 150 mcg/kg and above. In an oral study,
mometasone furoate increased resorptions and caused cleft palate and/or head
malformations (hydrocephaly and domed head) at 700 mcg/kg. At 2800 mcg/kg most
litters were aborted or resorbed. No toxicity was observed at 140 mcg/kg.
When rats received subcutaneous doses of mometasone
furoate throughout pregnancy or during the later stages of pregnancy, prolonged
and difficult labor and reduced the number of live births, birth weight, and
early pup survival were observed at 15 mcg/kg. Similar effects were not
observed at 7.5 mcg/kg.
8.2 Lactation
PLLR Conversion
Additions and/or revisions underlined:
Risk
Summary
There
are no data on the presence of mometasone furoate following topical
administration in animal or human milk, the effects on the breastfed infant, or
the effects on milk production. It is not known whether topical
administration of corticosteroids could result in sufficient systemic
absorption to produce detectable quantities in breast milk. To minimize
potential exposure to the breastfed infant via breast milk, use ELOCON cream on
the smallest area of skin and for the shortest duration possible while
breastfeeding. Advise breastfeeding women not to apply ELOCON cream directly to
the nipple and areola to avoid direct infant exposure [see Warnings and Precautions (5.1) and Use in Specific Populations (8.4)]. The developmental and health
benefits of breastfeeding should be considered along with the mother’s clinical
need for ELOCON cream and any potential adverse effects on the breastfed infant
from ELOCON cream or from the underlying maternal condition.
8.3 Pediatric Use
Additions and/or revisions underlined:
The
safety and effectiveness of ELOCON cream for the relief of the inflammatory and
pruritic manifestations of corticosteroid-responsive dermatoses have been
established in
pediatric patients 2 years of age and older. Use of ELOCON cream for this
indication is supported by evidence from a clinical trial in 24 subjects (19
subjects 2 to 12 years of age) with atopic dermatitis treated with ELOCON cream
once daily [see Adverse Reactions (6.1)
and Clinical Studies (14)].
The
safety and efficacy of ELOCON cream have not been established in pediatric
patients younger than 2 years of age. The safety and efficacy of ELOCON cream
use for longer than three weeks have not been established in pediatric patients
2 years of age and older.
The
following adverse reactions were reported to be possibly or probably related to
treatment with ELOCON cream during clinical trials in 4% of 182 pediatric
subjects 6 months to 2 years of age: decreased glucocorticoid levels, 2;
paresthesia, 2; folliculitis, 1; moniliasis, 1; bacterial infection, 1; skin
depigmentation, 1. The following signs of skin atrophy were also observed among
97 subjects treated with ELOCON cream in a clinical trial: shininess, 4;
telangiectasia, 1; loss of elasticity, 4; loss of normal skin markings, 4;
thinness, 1; and bruising, 1.
Endocrine
Adverse Reactions
Ninety-seven
pediatric subjects ages 6 to 23 months with atopic dermatitis were enrolled in
an open-label HPA axis safety study. ELOCON cream caused HPA axis
suppression in approximately 16% of pediatric subjects ages 6 to 23 months, who
showed normal adrenal function by Cortrosyn test before starting treatment, and
applied ELOCON over a mean body surface area of 41% (range 15%-94%). The criteria
for suppression were: basal cortisol level of less than or equal to 5 mcg/dL,
30-minute post-stimulation level of less than or equal to 18 mcg/dL, or an
increase of less than 7 mcg/dL. Follow-up testing 2 to 4 weeks after trial
completion, available for 5 of the subjects, demonstrated suppressed HPA axis
function in 1 subject, using these same criteria.
ELOCON
cream is not indicated for use in pediatric patients younger than 2 years of
age [see Clinical Pharmacology (12.2)].
Because
of a higher ratio of skin surface area to body mass, pediatric patients are at
a greater risk than adults of HPA axis suppression and Cushing’s syndrome when
they are treated with topical corticosteroids [see Warnings and Precautions (5.1)]. They are, therefore, also at
greater risk of adrenal insufficiency during and/or after withdrawal of
treatment. Pediatric patients may be more susceptible than adults to skin
atrophy, including striae, when they are treated with topical
corticosteroids.
