General: Systemic absorption of topical corticosteroids has produced
reversible hypothalamic-pituitary-adrenal (HPA) axis suppression, manifestations
of Cushing's syndrome, hyperglycemia, and glucosuria in some patients.
Conditions which augment systemic absorption include the application of the more potent steroids, use over large surface areas, prolonged use, and the addition of occlusive dressings.
If HPA axis suppression is noted (by using the urinary free cortisol and ACTH stimulation tests) an attempt should be made to withdraw the drug or to reduce the frequency of application.
Recovery of HPA axis function is generally prompt and complete upon discontinuation of the drug. Infrequently, signs and symptoms of steroid withdrawal may occur, requiring supplemental systemic corticosteroids.
Pediatric patients may absorb proportionally larger amounts of topical corticosteroids
and thus be more susceptible to systemic toxicity (see PRECAUTIONS —
Pediatric Use).
If irritation develops, topical corticosteroids should be discontinued and appropriate therapy instituted. In the presence of dermatological infections, the use of an appropriate antifungal or antibacterial agent should be instituted.
If a favorable response does not occur promptly, the corticosteroid should be discontinued until the infection has been adequately controlled.
Laboratory Tests: The urinary free cortisol test and the ACTH stimulation
test may be helpful in evaluating the HPA axis suppression.
Carcinogenesis, Mutagenesis, and Impairment of Fertility: Long-term
animal studies have not been performed to evaluate the carcinogenic potential
or the effect on fertility of topical corticosteriods. Studies to determine
mutagenicity with hydrocortisone have revealed negative results.
Pregnancy Category C: Corticosteroids are generally teratogenic in laboratory
animals when administered systemically at relatively low dosage levels. The
more potent corticosteroids have been shown to be teratogenic after dermal application
in laboratory animals. There are no adequate and well-controlled studies in
pregnant women on teratogenic effects from topically applied corticosteroids.
Therefore, topical corticosteroids should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Drugs of this class should not be used extensively on pregnant patients, in large amounts, or for prolonged periods of time.
Nursing Mothers: It is not known whether topical administration of corticosteroids
could result in sufficient systemic absorption to produce detectable quantities
in breast milk. Systemically administered corticosteroids are secreted into
breast milk in quantities not likely to have a deleterious effect on the infant.
Nevertheless, caution should be exercised when topical corticosteroids are administered
to a nursing woman.
USE IN PEDIATRIC PATIENTS: PEDIATRIC PATIENTS MAY DEMONSTRATE GREATER
SUSCEPTIBILITY TO TOPICAL CORTICOSTEROID-INDUCED HPA AXIS SUPPRESSION AND CUSHING'S
SYNDROME THAN MATURE PATIENTS BECAUSE OF A LARGER SKIN SURFACE AREA TO BODY
WEIGHT RATIO.
Hypothalamic-pituitary-adrenal (HPA) axis suppression, Cushing's syndrome, and intracranial hypertension have been reported in pediatric patients receiving topical corticosteroids. Manifestations of adrenal suppression in pediatric patients include linear growth retardation, delayed weight gain, low plasma cortisol levels, and absence of response to ACTH stimulation. Manifestations of intracranial hypertension include bulging fontanelles, headaches, and bilateral papilledema.
Administration of topical corticosteroids to pediatric patients should be limited to the least amount compatible with an effective therapeutic regimen. Chronic corticosteroid therapy may interfere with the growth and development of pediatric patients.
