PRECAUTIONS
Effects On Endocrine System
Systemic absorption of topical corticosteroids can
produce reversible hypothalamic-pituitary-adrenal (HPA) axis suppression with
the potential for glucocorticosteroid insufficiency. This may occur during
treatment or after withdrawal of treatment. Manifestations of Cushing's
syndrome, hyperglycemia, and glucosuria can also be produced in some patients
by systemic absorption of topical corticosteroids while on treatment. Factors
that predispose a patient using a topical corticosteroid to HPA axis
suppression include the use of high-potency steroids, large treatment surface
areas, prolonged use, use of occlusive dressings, altered skin barrier, liver
failure, and young age.
Because of the potential for systemic absorption, use of
topical corticosteroids may require that patients be periodically evaluated for
HPA axis suppression. This may be done by using the adrenocorticotropic hormone
(ACTH) stimulation test.
In a study evaluating the effects of mometasone furoate
ointment on the HPA axis, 15 grams were applied twice daily for 7 days to 6
adult subjects with psoriasis or atopic dermatitis. The results show that the
drug caused a slight lowering of adrenal corticosteroid secretion.
If HPA axis suppression is documented, an attempt should
be made to gradually withdraw the drug, to reduce the frequency of application,
or to substitute a less potent corticosteroid. Recovery of HPA axis function is
generally prompt upon discontinuation of topical corticosteroids. Infrequently,
signs and symptoms of glucocorticosteroid insufficiency may occur, requiring
supplemental systemic corticosteroids.
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].
Ophthalmic Adverse Reactions
Use of topical corticosteroids may increase the risk of
posterior subcapsular cataracts and glaucoma. Cataracts and glaucoma have been
reported in postmarketing experience with the use of topical corticosteroid
products, including the topical mometasone products [see ADVERSE REACTIONS].
Avoid contact of ELOCON Ointment with eyes. Advise
patients to report any visual symptoms and consider referral to an
ophthalmologist for evaluation.
Allergic Contact Dermatitis
If irritation develops, ELOCON Ointment should be
discontinued and appropriate therapy instituted. Allergic contact dermatitis
with corticosteroids is usually diagnosed by observing failure to heal rather
than noting a clinical exacerbation. Such an observation should be corroborated
with appropriate diagnostic patch testing.
Concomitant Skin Infections
If concomitant skin infections are present or develop, an
appropriate antifungal or antibacterial agent should be used. If a favorable
response does not occur promptly, use of ELOCON Ointment should be discontinued
until the infection has been adequately controlled.
Patient Counseling Information
Advise the patient to read the FDA-approved patient
labeling (PATIENT INFORMATION).
Inform patients of the following:
- Use ELOCON Ointment as directed by the physician. It is
for external use only.
- Avoid contact with the eyes.
- Advise patients to report any visual symptoms to their
healthcare providers.
- Do not use ELOCON Ointment on the face, underarms, or
groin areas.
- Do not use ELOCON Ointment for any disorder other than
that for which it was prescribed.
- Do not bandage or otherwise cover or wrap the treated
skin area so as to be occlusive, unless directed by the physician
- Report any signs of local adverse reactions to the
physician.
- Advise patients not to use ELOCON Ointment in the
treatment of diaper dermatitis. Do not apply ELOCON Ointment in the diaper
area, as diapers or plastic pants may constitute occlusive dressing.
- Discontinue therapy when control is achieved. If no
improvement is seen within 2 weeks, contact the physician.
- Do not use other corticosteroid-containing products with
ELOCON Ointment without first consulting with the physician.
Nonclinical Toxicology
Carcinogenesis, Mutagenesis, Impairment Of Fertility
Long-term animal studies have not been performed to
evaluate the carcinogenic potential of ELOCON Ointment. Long-term
carcinogenicity studies of mometasone furoate were conducted by the inhalation
route in rats and mice. In a 2-year carcinogenicity study in Sprague Dawley rats,
mometasone furoate demonstrated no statistically significant increase of tumors
at inhalation doses up to 67 mcg/kg (approximately 0.04 times the estimated
maximum clinical topical dose from ELOCON Ointment on a mcg/m² basis). In a
19-month carcinogenicity study in Swiss CD-1 mice, mometasone furoate
demonstrated no statistically significant increase in the incidence of tumors
at inhalation doses up to 160 mcg/kg (approximately 0.05 times the estimated
maximum clinical topical dose from ELOCON Ointment on a mcg/m² basis).
Mometasone furoate increased chromosomal aberrations in
an in vitro Chinese hamster ovary cell assay, but did not increase chromosomal
aberrations in an in vitro Chinese hamster lung cell assay. Mometasone furoate
was not mutagenic in the Ames test or mouse lymphoma assay, and was not
clastogenic in an in vivo mouse micronucleus assay, a rat bone marrow
chromosomal aberration assay, or a mouse male germ-cell chromosomal aberration
assay. Mometasone furoate also did not induce unscheduled DNA synthesis in vivo
in rat hepatocytes.
In reproductive studies in rats, impairment of fertility
was not produced in male or female rats by subcutaneous doses up to 15 mcg/kg
(approximately 0.01 times the estimated maximum clinical topical dose from
ELOCON Ointment on a mcg/m² basis).
Use In Specific Populations
Pregnancy
Teratogenic Effects
Pregnancy Category C
There are no adequate and well-controlled studies in
pregnant women. Therefore, ELOCON Ointment should be used during pregnancy only
if the potential benefit justifies the potential risk to the fetus.
Corticosteroids have been shown to be teratogenic in
laboratory animals when administered systemically at relatively low dosage
levels. Some corticosteroids have been shown to be teratogenic after dermal
application in laboratory animals.
When administered 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.
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. (Doses of 20, 60, and 180 mcg/kg
in the mouse are approximately 0.01, 0.02, and 0.05 times the estimated maximum
clinical topical dose from ELOCON Ointment on a mcg/m² basis.)
In rats, mometasone furoate produced umbilical hernias at
topical doses of 600 mcg/kg and above. A dose of 300 mcg/kg produced delays in
ossification, but no malformations. (Doses of 300 and 600 mcg/kg in the rat are
approximately 0.2 and 0.4 times the estimated maximum clinical topical dose
from ELOCON Ointment on a mcg/m² basis.)
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 (approximately 0.2 times
the estimated maximum clinical topical dose from ELOCON Ointment on a mcg/m² basis).
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. (Doses of 140, 700, and 2800 mcg/kg in the rabbit are
approximately 0.2, 0.9, and 3.6 times the estimated maximum clinical topical
dose from ELOCON Ointment on a mcg/m² basis.)
When rats received subcutaneous doses of mometasone
furoate throughout pregnancy or during the later stages of pregnancy, 15 mcg/kg
caused prolonged and difficult labor and reduced the number of live births,
birth weight, and early pup survival. Similar effects were not observed at 7.5
mcg/kg. (Doses of 7.5 and 15 mcg/kg in the rat are approximately 0.005 and 0.01
times the estimated maximum clinical topical dose from ELOCON Ointment on a
mcg/m² basis.)
Nursing Mothers
Systemically administered corticosteroids appear in human
milk and could suppress growth, interfere with endogenous corticosteroid
production, or cause other untoward effects. It is not known whether topical
administration of corticosteroids could result in sufficient systemic
absorption to produce detectable quantities in human milk. Because many drugs
are excreted in human milk, caution should be exercised when ELOCON Ointment is
administered to a nursing woman.
Pediatric Use
ELOCON Ointment may be used with caution in pediatric
patients 2 years of age or older, although the safety and efficacy of drug use
for longer than 3 weeks have not been established. Since safety and efficacy of
ELOCON Ointment have not been established in pediatric patients below 2 years
of age, its use in this age group is not recommended.
ELOCON Ointment caused HPA axis suppression in
approximately 27% of pediatric subjects ages 6 to 23 months, who showed normal
adrenal function by Cortrosyn test before starting treatment, and were treated
for approximately 3 weeks over a mean body surface area of 39% (range 15%-99%).
The criteria for suppression were: basal cortisol level of ≤5 mcg/dL,
30-minute post-stimulation level of ≤18 mcg/dL, or an increase of <7
mcg/dL. Follow-up testing 2 to 4 weeks after stopping treatment, available for
8 of the subjects, demonstrated suppressed HPA axis function in 3 subjects,
using these same criteria. Long-term use of topical corticosteroids has not
been studied in this population [see CLINICAL PHARMACOLOGY].
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. They are, therefore, also at greater risk of
glucocorticosteroid 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. Pediatric
patients applying topical corticosteroids to greater than 20% of body surface
are at higher risk of HPA axis suppression.
HPA axis suppression, Cushing's syndrome, linear growth
retardation, delayed weight gain, and intracranial hypertension have been
reported in children receiving topical corticosteroids. Manifestations of
adrenal suppression in children include low plasma cortisol levels and absence
of response to ACTH stimulation. Manifestations of intracranial hypertension
include bulging fontanelles, headaches, and bilateral papilledema.
ELOCON Ointment should not be used in the treatment of
diaper dermatitis.
Geriatric Use
Clinical trials of ELOCON Ointment included 310 subjects
who were 65 years of age and over and 57 subjects who were 75 years of age and
over. No overall differences in safety or effectiveness were observed between
these subjects and younger subjects, and other reported clinical experience has
not identified differences in responses between the elderly and younger
subjects. However, greater sensitivity of some older individuals cannot be
ruled out.
