PRECAUTIONS
General
Systemic absorption of topical corticosteroids can produce
reversible hypothalamic-pituitary-adrenal (HPA) axis suppression with the
potential for glucocorticosteroid insufficiency after withdrawal of treatment.
Manifestations of Cushing syndrome, hyperglycemia, and glucosuria can also be
produced in some patients by systemic absorption of topical corticosteroids
while on treatment. Patients applying a topical steroid to a large surface area
or to areas under occlusion should be evaluated periodically for evidence of
HPA axis suppression. This may be done by using the ACTH stimulation, A.M. plasma cortisol, and urinary free cortisol tests.
The effects of ACLOVATE® (alclometasone dipropionate) Cream and Ointment on the HPA axis
have been evaluated. In one study, ACLOVATE® (alclometasone dipropionate) Cream and Ointment were applied to
30% of the body twice daily for 7 days, and occlusive dressings were used in
selected patients either 12 hours or 24 hours daily. In another study,
ACLOVATE® (alclometasone dipropionate) Cream was applied to 80% of the body surface of normal subjects twice
daily for 21 days with daily 12-hour periods of whole body occlusion. Average
plasma and urinary free cortisol levels and urinary levels of
17-hydroxysteroids were decreased (about 10%), suggesting suppression of the
HPA axis under these conditions. Plasma cortisol levels have also been
demonstrated to decrease in pediatric patients treated twice daily for 3 weeks
without occlusion.
If HPA axis suppression is noted, an attempt should be made
to 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. For information on systemic supplementation, see prescribing
information for those products.
Pediatric patients may be more susceptible to systemic
toxicity from equivalent doses due to their larger skin surface area to body
mass ratios (see PRECAUTIONS: Pediatric Use).
If irritation develops, ACLOVATE® (alclometasone dipropionate) Cream or Ointment should
be discontinued and appropriate therapy instituted. Allergic contact dermatitis
with corticosteroids is usually diagnosed by observing a failure to heal
rather than noting a clinical exacerbation, as with most topical products not
containing corticosteroids. Such an observation should be corroborated with
appropriate diagnostic patch testing. 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 ACLOVATE® (alclometasone dipropionate) Cream
or Ointment should be discontinued until the infection has been adequately
controlled.
In a transgenic mouse study, chronic use of Aclovate (alclometasone dipropionate) cream
led to an increased number of animals with benign neoplasms of the skin at the
treatment site (see PRECAUTIONS: Carcinogenesis, Mutagenesis, and
Impairment of Fertility). The clinical relevance of the findings in animal
studies to humans is not clear.
Laboratory Tests
The following tests may be helpful in evaluating patients
for HPA axis suppression:
ACTH stimulation test
A.M. plasma cortisol test
Urinary free cortisol test
Carcinogenesis, Mutagenesis, Impairment of Fertility
Systemic long-term animal studies have not been performed to
evaluate the carcinogenic potential of alclometasone dipropionate. The effects
of alclometasone dipropionate on mutagenesis or fertility have not been
evaluated.
In a 26-week dermal carcinogenicity study conducted in transgenic
(Tg.AC) mice, topical application once daily of both the vehicle cream and the
0.05% alclometasone dipropionate cream significantly increased the incidence of
benign neoplasms of the skin in both sexes at the treatment site when compared
to untreated controls. This suggests that the positive effect may be associated
with the vehicle application. The clinical relevance of the findings in animals
to humans is not clear.
Pregnancy
Teratogenic Effects
Pregnancy Category C. 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. There are no adequate and
well-controlled studies in pregnant women. ACLOVATE® (alclometasone dipropionate) Cream or Ointment should
be used during pregnancy only if the potential benefit justifies the potential
risk to the fetus.
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 topical 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 ACLOVATE® (alclometasone dipropionate) Cream or
Ointment is administered to a nursing woman.
Pediatric Use
ACLOVATE® (alclometasone dipropionate) Cream and Ointment may be used with caution in
pediatric patients 1 year of age or older, although the safety and efficacy of
drug use for longer than 3 weeks have not been established. Use of ACLOVATE® (alclometasone dipropionate)
Cream and Ointment is supported by results from adequate and well-controlled
studies in pediatric patients with corticosteroid-responsive dermatoses. Since
the safety and efficacy of ACLOVATE® (alclometasone dipropionate) Cream and Ointment have not been
established in pediatric patients below 1 year of age, its use in this
age-group is not recommended. 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 syndrome when they are treated with topical
corticosteroids. They are therefore also at greater risk of adrenal
insufficiency during and/or after withdrawal of treatment. Adverse effects,
including striae, have been reported with inappropriate use of topical
corticosteroids in infants and children. Pediatric patients applying ACLOVATE® (alclometasone dipropionate)
Cream or Ointment to > 20% of the body surface area are at higher risk for
HPA axis suppression.
HPA axis suppression, Cushing syndrome, linear growth
retardation, delayed weight gain, and intracranial hypertension have been
reported in pediatric patients receiving topical corticosteroids.
Manifestations of adrenal suppression in pediatric patients include low plasma
cortisol levels and absence of response to ACTH stimulation. Manifestations of
intracranial hypertension include bulging fontanelles, headaches, and bilateral papilledema.
ACLOVATE® (alclometasone dipropionate) Cream or Ointment should not be used in the treatment
of diaper dermatitis.
Geriatric Use
A limited number of patients at or above 65 years of age
have been treated with ACLOVATE® (alclometasone dipropionate) Cream and Ointment in US clinical trials. The
number of patients is too small to permit separate analysis of efficacy and
safety. No adverse events were reported with ACLOVATE® (alclometasone dipropionate) Ointment in geriatric
patients, and the single adverse reaction reported with ACLOVATE® (alclometasone dipropionate) Cream in this
population was similar to those reactions reported by younger patients. Based
on available data, no adjustment of dosage of ACLOVATE® (alclometasone dipropionate) Cream and Ointment in
geriatric patients is warranted.
