General: TEMOVATE Cream and Ointment should not be used in the treatment
of rosacea or perioral dermatitis, and should not be used on the face, groin,
or axillae.
Systemic absorption of topical corticosteroids can produce reversible HPA axis
suppression with the potential for giucocorticosteroid insufficiency after withdrawal
from treatment. Manifestations of Cushing's syndrome, hyperglycemia, and glucosuria
can also be produced in some patients by systemic absorption of topical corticosteroids
while on therapy.
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. Patients receiving super-potent corticosteroids should not be treated for more than 2 weeks at a time, and only small areas should be treated at any one time due to the increased risk of HPA suppression.
TEMOVATE Cream and Ointment produced HPA axis suppression when used at doses
as low as 2 g/day for 1 week in patients with eczema.
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 that require 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 to body mass ratios (see PRECAUTIONS:
Pediatric Use).
If irritation develops, TEMOVATE Cream and Ointment should be discontinued
and appropriate therapy instituted. Allergic contact dermatitis with corticosteroids
is usually diagnosed by observing a failure to heat 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 TEMOVATE Cream and Ointment should be discontinued untii the
infection has been adequately controlled.
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: Long-term animal
studies have not been performed to evaluate the carcinogenic potential of clobetasol
propionate.
Studies in the rat following subcutaneous administration at dosage levels up to 50 mcg/kg per day revealed that the females exhibited an increase in the number of resorbed embryos and a decrease in the number of living fetuses at the highest dose.
Clobetasol propionate was nonmutagenic in 3 different test systems: the Ames
test, the Saccharomyces cecevisiae gene conversion assay, and the E
.coli B WP2 fluctuation test.
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 to laboratory animals.
Clobetasol propionate has not been tested for teratogenicity when applied topically;
however, it is absorbed percutaneously, and when administered subcutaneously
it was a significant teratogen in both the rabbit and mouse. Clobetasol propionate
has greater teratogenic potential than steroids that are less potent.
Teratogenicity studies in mice using the subcutaneous route resulted in fetotoxicity
at the highest dose tested (1 mg/kg) and teratogenicity at all dose levels tested
down to 0.03 mg/kg. These doses are approximately 1.4 and 0.04 times, respectively,
the human topical dose of TEMOVATE Cream and Ointment. Abnormalities seen included
cleft palate and skeletal abnormalities.
In rabbits, clobetasol propionate was teratogenic at doses of 3 and 10 mcg/kg. These doses are approximately 0.02 and 0.05 times, respectively, the human topical dose of TEMOVATE Cream and Ointment. Abnormalities seen included cleft palate, cranioschisis, and other skeletal abnormalities.
There are no adequate and well-controlled studies of the teratogenic potential
of clobetasol propionate in pregnant women. TEMOVATE Cream and 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 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 TEMOVATE Cream or Ointment is
administered to a nursing woman.
Pediatric Use: Safety and effectiveness of TEMOVATE Cream and Ointment
in pediatric patients have not been established. Use in pediatric patients under
12 years of age 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's syndrome when they are treated with topical corticosteroids.
They are therefore also at greater risk of adrenal insufficiency during or after
withdrawal of treatment. Adverse effects including striae have been reported
with inappropriate use of topical corticosteroids In infants and children.
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 an absence of response to ACTH stimulation. Manifestations
of intracranial hypertension include bulging fontanelles, headaches, and bilateral
papilledema.
Geriatric Use: A limited number of patients at or above 65 years of
age have been treated with TEMOVATE Cream (n = 231) and with TEMOVATE Ointment
(n = 101) in US and non-US clinical trials. While the number of patients is
too small to permit separate analysis of efficacy and safety, the adverse reactions
reported in this population were similar to those reported by younger patients.
Based on available data, no adjustment of dosage of TEMOVATE Cream and Ointment
in geriatric patients is warranted.
