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.
Halobetasol propionate ointment, 0.05% 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 PRECAUTIONS: Pediatric Use).
If irritation develops, halobetasol propionate ointment, 0.05% 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 halobetasol propionate ointment, 0.05% should be
discontinued until the infection has been adequately controlled.
Halobetasol propionate cream, 0.05% 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.
