WARNINGS
No information provided.
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's 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. 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.
ULTRAVATE (halobetasol propionate cream) Cream produced
HPA axis suppression
when used in divided doses at 7 grams per
day for one week in patients with psoriasis. These effects
were reversible
upon discontinuation of treatment.
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 to body
mass ratios (See Pediatric
Use).
If irritation develops,
ULTRAVATE (halobetasol propionate cream) Cream 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
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 ULTRAVATE (halobetasol propionate
cream) Cream should be discontinued until the infection
has been adequately controlled.
ULTRAVATE (halobetasol propionate cream) Cream should not
be used in the treatment
of rosacea or perioral
dermatitis, and it should not be used on the face, groin,
or in the axillae.
Information for Patients
See PATIENT INFORMATION
section.
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, and Impairment of Fertility
Long-term animal studies
have not been performed to evaluate the carcinogenic
potential of halobetasol
propionate.
Positive mutagenicity effects were observed in two genotoxicity
assays. Halobetasol propionate was positive
in a Chinese hamster
micronucleus
test, and in a mouse
lymphoma gene
mutation assay
in vitro.
Studies in the rat following
oral administration
at dose levels up to
50 mg/kg/day indicated no impairment
of fertility or
general reproductive
performance.
In other genotoxicity testing, halobetasol propionate was
not found to be genotoxic
in the Ames/Salmonella assay, in the sister
chromatid exchange
test in somatic
cells of the Chinese hamster, in chromosome
aberration studies
of germinal and somatic
cells of rodents, and in a mammalian spot
test to determine point
mutations.
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.
Halobetasol propionate has been shown to be teratogenic
in SPF rats and chinchilla-type rabbits when given systemically
during gestation
at doses of 0.04 to 0.1 mg/kg in rats and 0.01 mg/kg in
rabbits. These doses are approximately 13, 33 and 3 times,
respectively, the human
topical dose
of ULTRAVATE (halobetasol propionate cream) Cream. Halobetasol
propionate was embryotoxic in rabbits but not in rats.
Cleft palate was observed
in both rats and rabbits. Omphalocele was seen in rats,
but not in rabbits.
There are no adequate and well-controlled studies of the
teratogenic potential
of halobetasol propionate in pregnant
women. ULTRAVATE (halobetasol propionate cream) Cream 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 ULTRAVATE (halobetasol
propionate cream) Cream is administered to a nursing
woman.
Pediatric Use
Safety and effectiveness
of ULTRAVATE (halobetasol propionate cream) Cream in pediatric
patients have not been established and use in pediatric
patients under 12 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.
