Revised: 11/2023
Shake can prior to use and turn can completely upside down to dispense. Apply Halobetasol Propionate Topical Foam as a thin uniform film to the affected skin twice daily for up to two weeks. Rub in gently. Wash hands after applying the product.
Discontinue therapy when control is achieved. If no improvement is seen within two weeks, reassessment of the diagnosis may be necessary.
Treatment beyond two weeks is not recommended and the total dosage should not exceed 50 grams per week because of the potential for the drug to suppress the hypothalamic-pituitary-adrenal (HPA) axis [see Warnings and Precautions (5.1)]. Do not use with occlusive dressings unless directed by a physician.
Avoid use on the face, groin, or axillae.
Avoid contact with eyes. Wash hands after each application, unless it is for treatment of the hands.
Halobetasol propionate topical foam is for topical use only.
Halobetasol propionate topical foam is not for ophthalmic, oral, or intravaginal use.
Halobetasol Propionate Topical Foam is a topical corticosteroid that has been shown to suppress the hypothalamic-pituitary-adrenal (HPA) axis.
Systemic effects of topical corticosteroids may include reversible HPA axis suppression, with the potential for glucocorticosteroid insufficiency. This may occur during treatment or upon withdrawal of treatment of the topical corticosteroid. The potential for hypothalamic-pituitary-adrenal (HPA) suppression with Halobetasol Propionate Topical Foam was evaluated in the following studies:
Because of the potential for systemic absorption, use of topical corticosteroids, including Halobetasol Propionate Topical Foam, may require that patients be evaluated periodically for evidence of HPA axis suppression. Factors that predispose a patient using a topical corticosteroid to HPA axis suppression include the use of more potent corticosteroids, use over large surface areas, prolonged use, occlusive use, use on an altered skin barrier, concomitant use of multiple corticosteroid-containing products, liver failure, and young age. An ACTH stimulation test may be helpful in evaluating patients for HPA axis suppression.
If HPA axis suppression is documented, attempt to gradually withdraw the drug, reduce the frequency of application, or substitute a less potent steroid. Manifestations of adrenal insufficiency may require supplemental systemic corticosteroids. Recovery of HPA axis function is generally prompt and complete upon discontinuation of topical corticosteroids.
Systemic effects of topical corticosteroids may also include Cushing's syndrome, hyperglycemia, and glucosuria. Use of more than one corticosteroid-containing product at the same time may increase the total systemic exposure to topical corticosteroids.
Pediatric patients may be more susceptible than adults to systemic toxicity from the use of topical corticosteroids due to their larger surface-to-body mass ratios [see Use in Specific Populations (8.4)].
Local adverse reactions from topical corticosteroids may include atrophy, striae, telangiectasias, burning, itching, irritation, dryness, folliculitis, acneiform eruptions, hypopigmentation, perioral dermatitis, allergic contact dermatitis, secondary infection, and miliaria. These may be more likely to occur with occlusive use, prolonged use, or use of higher potency corticosteroids, including Halobetasol Propionate Topical Foam. Some local adverse reactions may be irreversible.
Use of topical corticosteroids may increase the risk of posterior subcapsular cataracts and glaucoma. Cataracts and glaucoma have been reported in postmarketing experience with the use of topical corticosteroid products.
Advise patients to report any visual symptoms and consider referral to an ophthalmologist for evaluation.
Use an appropriate antimicrobial agent if a skin infection is present or develops. If a favorable response does not occur promptly, discontinue use of Halobetasol Propionate Topical Foam until the infection has been adequately treated.
Allergic contact dermatitis with corticosteroids is usually diagnosed by observing failure to heal rather than noting a clinical exacerbation. Consider confirmation of a clinical diagnosis of allergic contact dermatitis by appropriate patch testing. Discontinue Halobetasol Propionate Topical Foam if allergic contact dermatitis is established.
The following adverse reactions are discussed in greater detail in other sections of the label:
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
In randomized, multicenter, vehicle-controlled clinical trials, 351 adults with plaque psoriasis were treated with Halobetasol Propionate Topical Foam twice daily for up to two weeks (up to approximately 50 grams per week). Table 1 presents selected adverse reactions that occurred in at least 1% of subjects.

Because the reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
The following local adverse reactions have been reported with topical corticosteroids: folliculitis, acneiform eruptions, hypopigmentation, perioral dermatitis, allergic contact dermatitis, secondary infection, irritation, striae, and miliaria. They may occur more frequently with the use of occlusive dressings and higher potency corticosteroids, such as halobetasol propionate.
Risk Summary
There are no available data on Halobetasol Propionate Topical Foam use in pregnant women to inform a drug-associated risk for adverse developmental outcomes. In animal reproduction studies, increased malformations, including cleft palate and omphalocele, were observed after oral administration of halobetasol propionate during organogenesis to pregnant rats and rabbits. No comparisons of animal exposure with human exposure may be calculated due to minimal systemic exposure in humans after topical administration of Halobetasol Propionate Topical Foam [see Clinical Pharmacology (12.3)].
The background risk of major birth defects and miscarriage for the indicated population are unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively.
Data
Animal Data
Halobetasol propionate has been shown to cause malformations in rats and rabbits when given orally during organogenesis at doses of 0.04 to 0.1 mg/kg/day in rats and 0.01 mg/kg/day in rabbits. 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.
Risk Summary
There are no data on the presence of halobetasol propionate or its metabolites in human milk, the effects on the breastfed infant, or the effects on milk production after topical application to women who are breastfeeding.
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. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for Halobetasol Propionate Topical Foam and any potential adverse effects on the breastfed infant from Halobetasol Propionate Topical Foam or from the underlying maternal condition.
Safety and effectiveness of Halobetasol Propionate Topical Toam in patients younger than 12 years of age have not been established; therefore, use in children younger than 12 years is not recommended.
The safety and effectiveness of Halobetasol Propionate Topical Foam for the treatment of stable plaque psoriasis in subjects 12 to less than 18 years of age is supported by evidence from adequate and well-controlled studies in adults and from one open-label safety study in 24 subjects aged 12 to less than 18 years. Subjects 12 to less than 18 years with stable plaque psoriasis covering a minimum of 10% of the total body surface area at baseline were treated twice daily for 2 weeks with Halobetasol Propionate Topical Foam. Hypothalamic-pituitary adrenal (HPA) axis function (ACTH stimulation test) was evaluated in a subset of 23 subjects. After 2 weeks of treatment, 6 of 23 subjects (26.1%) experienced laboratory evidence of adrenal suppression (i.e., cortisol serum level of ≤18 µg/dL) that recovered upon retesting after at least 4 weeks of stopping the treatment [see Clinical Pharmacology (12.2)].
Because of higher skin surface area to body mass ratios, 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 reactions including striae have been reported with use of topical corticosteroids in infants and children [see Warnings and Precautions (5.1)].
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 [see Warnings and Precautions (5.1)].
Topically applied Halobetasol Propionate Topical Foam can be absorbed in sufficient amounts to produce systemic effects [see Warnings and Precautions (5.1)].
Halobetasol Propionate Topical Foam is a hydroethanolic aerosol foam that contains a corticosteroid, halobetasol propionate. The chemical name of halobetasol propionate is 21-chloro-6α, 9-difluoro-11β, 17-dihydroxy-16β-methylpregna-1, 4-diene-3,20-dione 17-propionate. Halobetasol propionate is a white to off-white crystalline powder with a molecular weight of 484.96 and a molecular formula of C25H31ClF2O5. It has the following structural formula:
It is practically insoluble in water and freely soluble in dichloromethane and in acetone. Each gram of Halobetasol Propionate Topical Foam contains 0.5 mg of halobetasol propionate in a white to off-white foam base consisting of alcohol (dehydrated), benzoic acid, cetostearyl alcohol, emulsifying wax, polyoxyl 20 cetostearyl ether, propylene glycol and purified water. Halobetasol Propionate Topical Foam is dispensed from an aluminum can pressurized with a hydrocarbon (isobutane and propane) propellant.
Corticosteroids play a role in cellular signaling, immune function, inflammation, and protein regulation; however, the precise mechanism of action in plaque psoriasis is unknown.
Vasoconstrictor Assay
A vasoconstrictor assay in healthy patients with Halobetasol Propionate Topical Foam, 0.05% indicated that the formulation is in the super-high range of potency as compared to other topical corticosteroids; however, similar blanching scores do not necessarily imply therapeutic equivalence.
Hypothalamic-pituitary-adrenal (HPA) axis suppression
The potential for hypothalamic-pituitary-adrenal (HPA) suppression was evaluated in the following two studies. In both studies, the criteria for HPA-axis suppression was a serum cortisol level of less than or equal to 18 micrograms per deciliter 30 minutes after stimulation with cosyntropin (adrenocorticotropic hormone, ACTH). In the first study, Halobetasol Propionate Topical Foam was applied to 25 adult subjects with moderate to severe plaque psoriasis involving a mean body surface area of 18.4%. A mean dose of 3.7 g of Halobetasol Propionate Topical Foam was applied twice daily for two weeks and produced laboratory evidence of HPA axis suppression in 6 of 25 (24%) subjects. All subjects returned to normal HPA axis function at follow-up at least 4 weeks after stopping the treatment.
In the second study, Halobetasol Propionate Topical Foam was applied to 24 subjects 12 to less than 18 years of age with stable plaque psoriasis with a mean percent BSA of 15.1% (range of 11% to 23%). The mean dose of Halobetasol Propionate Topical Foam used was 3.1 grams, which was applied twice daily for two weeks. In the study, 24 subjects completed the study, and 23 subjects had evaluable ACTH stimulation tests. HPA axis suppression was observed in 6 of the 23 subjects (26.1%), and all subjects returned to normal HPA axis function at follow-up at least 4 weeks after stopping the treatment.
The extent of percutaneous absorption of topical corticosteroids is determined by many factors, including the vehicle, the integrity of the epidermal barrier, and the use of occlusive dressings. Topical corticosteroids can be absorbed from normal intact skin. Inflammation and/or other disease processes in the skin may increase percutaneous absorption.
In the HPA-axis and pharmacokinetic study, as described above in Clinical Pharmacology (12.2), pharmacokinetics was evaluated in a subgroup of 23 adult subjects with moderate to severe plaque psoriasis following twice daily treatment for 14 days. Plasma concentration of halobetasol propionate (HBP) was measurable in all subjects and steady state was achieved by Day 14. The mean (± standard deviation) Cmax concentration for HBP on Day 14 was 199.7 ± 217.3 pg/mL, with the corresponding median Tmax value of 1 hour (range 0 – 12 hours); mean area under the halobetasol propionate concentration versus time curve over the dosing interval (AUCt) was 1434.9 ± 1310.6 pg∙h/mL.
In the HPA axis study in subjects 12 to less than 18 years [see Clinical Pharmacology (12.2)], trough plasma concentrations of HBP were measured on Day 8 and Day 15 in 23 subjects following twice daily treatment for 14 days. On Day 8, nine (9) of the 23 evaluable subjects had morning trough concentrations of halobetasol propionate in plasma that were above the quantifiable limit (≥20.0 pg/mL); mean halobetasol concentration was 154.6 ± 308.67 pg/mL. Similarly, on Day 15, nine (9) of the 23 evaluable subjects had morning trough concentrations of halobetasol propionate above the quantifiable limit; mean halobetasol concentration was 59.9 ± 90.15 pg/mL. Of the 9 subjects with quantifiable plasma concentrations at Day 15, seven (7) also had quantifiable plasma concentrations at Day 8.
Long-term animal studies have not been performed to evaluate the carcinogenic potential of halobetasol propionate.
In a 90-day repeat-dose toxicity study in rats, topical administration of Halobetasol Propionate Topical Foam at dose concentrations from 0.005% to 0.05% or from 0.011 to 0.11 mg/kg/day of halobetasol propionate resulted in a toxicity profile consistent with long-term exposure to corticosteroids including adrenal atrophy, histopathological changes in several organ systems indicative of severe immune suppression, and opportunistic fungal and bacterial infections. A no observable adverse effect level could not be determined in this study. Although the clinical relevance of the findings in animals to humans is not clear, sustained glucocorticoid-related immune suppression may increase the risk of infection and possibly the risk of carcinogenesis.
Halobetasol propionate was not found to be genotoxic in the Ames/Salmonella assay, in the Chinese hamster CHO/HGPRT assay, in the mouse micronucleus test, in the sister chromatid exchange test in somatic cells of the Chinese hamster, or in the chromosome aberration test in somatic cells of Chinese hamsters. Positive mutagenicity effects were observed in two genotoxicity assays: Chinese hamster nuclear anomaly test and mouse lymphoma gene mutation assay in vitro.
Studies in the rat following oral administration at dose levels up to 0.05 mg/kg/day indicated no impairment of fertility or general reproductive performance.
Halobetasol Propionate Topical Foam was evaluated for the treatment of moderate to severe plaque psoriasis in two multicenter, randomized, double-blind, vehicle-controlled studies (Study 1 [NCT02368210] and Study 2 [NCT02742441]).
These studies were conducted in 560 subjects 18 years of age and older with plaque psoriasis involving between 2% and 12% body surface area. Baseline disease severity was determined using a static, five-level Investigator's Global Assessment (IGA) scale, on which a subject scored either moderate or severe. Overall, approximately 60% of subjects were male and approximately 90% were Caucasian.
Subjects applied Halobetasol Propionate Topical Foam or vehicle to all affected areas twice daily for up to 14 consecutive days.
The primary measure of efficacy was Overall Treatment Success, defined as the proportion of subjects who were cleared or almost cleared with at least a two-grade improvement from baseline at Week 2 (end of treatment) based on the IGA. The studies also evaluated treatment success for the individual signs of psoriasis (plaque elevation, scaling, and erythema) at the end of treatment. Table 2 presents these results.
