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.
Hydrocortisone valerate cream USP, 0.2% and hydrocortisone valerate ointment
USP, 0.2% have produced mild, reversible adrenal suppression in adult patients
when used under occlusion for 5 days, 15 grams twice a day over 25 to 60% body
surface area or when used three times a day over 20 to 30% body surface area to
treat psoriasis for 3-4 weeks.
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 these 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, hydrocortisone valerate cream USP, 0.2% or
hydrocortisone valerate ointment USP, 0.2% 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 hydrocortisone valerate cream USP, 0.2% or
hydrocortisone valerate ointment USP, 0.2% should be discontinued until the
infection has been adequately controlled.
Information for Patients
Patients using topical corticosteroids should receive the
following information and instructions:
- This medication is to be used as directed by the physician. It is for
external use only. Avoid contact with the eyes.
- This medication should not be used for any disorder other than that for
which it was prescribed.
- The treated skin area should not be bandaged, otherwise covered or wrapped,
so as to be occlusive unless directed by the physician.
- Patients should report to their physician any signs of local adverse
reactions.
- Hydrocortisone valerate cream USP, 0.2% or hydrocortisone valerate ointment
USP, 0.2% should not be applied in the diaper areas as diapers or plastic pants
may constitute occlusive dressings. (See DOSAGE
AND ADMINISTRATION.)
- This medication should not be used on the face, underarms, or groin areas
unless directed by the physician.
- As with other corticosteroids, therapy should be discontinued when control
is achieved. If no improvement is seen within 2 weeks, contact the
physician.
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 hydrocortisone valerate. Hydrocortisone valerate cream
USP, 0.2% and hydrocortisone valerate ointment USP, 0.2% were shown to be
non-mutagenic in the Ames-Salmonella/Microsome Plate Test. There are no studies
which assess the effects of hydrocortisone valerate on fertility and general
reproductive performance.
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.
Dermal embryofetal developmental studies were conducted in rabbits and rats
with hydrocortisone valerate cream, 0.2%. Hydrocortisone valerate cream, 0.2%,
was administered topically for 4 hours/day, rather than the preferred 24
hours/day, during the period of organogenesis in rats (gestational days 5-16)
and rabbits (gestational days 6-19). Topical doses of hydrocortisone valerate up
to 9 mg/kg/day (54 mg/m2/day) were administered to rats
and 5 mg/kg/day (60 mg/m2/day) were administered to
rabbits. In the absence of maternal toxicity, a significant increase in delayed
skeletal ossification in fetuses was noted at 9 mg/kg/day [2.5× the Maximum
Recommended Human Dose (MRHD) based on body surface area (BSA) comparisons] in
the rat study. No malformations in the fetuses were noted at 9 mg/kg/day (2.5×
MRHD based on BSA comparisons) in the rat study. Indicators of embryofetal
toxicity, significant decrease in fetal weight at 2 mg/kg/day (1× MRHD based on
BSA) and a significant increase in post-implantation loss and embryo resorption
at 5 mg/kg (3× MRHD based on BSA), were noted in the rabbit study. A significant
increase in delayed skeletal ossification in fetuses was noted at 5 mg/kg/day
(3× the MRHD based on BSA comparisons) in the rabbit study. Increased numbers of
fetal malformations (e.g., cleft palate, omphalocele and clubbed feet) were
noted at 5 mg/kg/day (3× MRHD based on BSA comparisons) in the rabbit study.
There are no adequate and well-controlled studies in pregnant women.
Hydrocortisone valerate cream USP, 0.2% or hydrocortisone valerate ointment USP,
0.2% 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 hydrocortisone valerate cream USP, 0.2%
or hydrocortisone valerate ointment USP, 0.2% is administered to a nursing
woman.
Pediatric Use
Safety of this product in pediatric patients has not been
established. There is no data on adrenal suppression and/or growth
suppression.
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 a 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. (See PRECAUTIONS)
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
Clinical studies of hydrocortisone valerate cream USP, 0.2% and
hydrocortisone valerate ointment USP, 0.2% did not include sufficient numbers of
subjects aged 65 and over to determine whether they respond differently from
younger subjects. Other reported clinical experience has not identified
differences in responses between the elderly and younger patients.
