FULL PRESCRIBING INFORMATION: CONTENTS*
Clobetasol propionate foam is a corticosteroid indicated for treatment of moderate to severe plaque psoriasis of the scalp and mild to moderate plaque psoriasis of non-scalp regions of the body excluding the face and intertriginous areas in patients 12 years and older.
Apply a thin layer of clobetasol propionate foam to the affected skin areas twice daily.
Clobetasol propionate foam is a super-high-potency topical corticosteroid; therefore, limit treatment to 2 consecutive weeks. Patients should not use greater than 50 grams per week or more than 21 capfuls per week because of the potential for the drug to suppress the hypothalamic-pituitary-adrenal (HPA) axis [see Warnings and Precautions (5.1)].
Therapy should be discontinued when control is achieved.
Clobetasol propionate foam should not be used with occlusive dressings unless directed by a physician.
Clobetasol propionate foam is for topical use only. It is not for oral, ophthalmic, or intravaginal use.
Avoid contact with eyes. Wash hands after each application.
Avoid use on the face, groin, or axillae, or if skin atrophy is present at the treatment site.
Clobetasol propionate foam, 0.05% contains 0.5 mg of clobetasol propionate, USP per gram.
Clobetasol propionate foam can cause reversible hypothalamic-pituitary-adrenal (HPA) axis suppression with the potential for glucocorticosteroid insufficiency. This may occur during treatment or after withdrawal of treatment. Factors that predispose a patient to HPA axis suppression include the use of high-potency steroids, large treatment surface areas, prolonged use, use of occlusive dressings, altered skin barrier, liver failure, and young age. Evaluation for HPA axis suppression may be done by using the adrenocorticotropic hormone (ACTH) stimulation test.
In a trial evaluating the effects of clobetasol propionate foam on the HPA axis, 13 subjects applied clobetasol propionate foam to at least 20% of involved body surface area for 14 days. HPA axis suppression was identified in 5 out of 13 subjects (38%) [see Clinical Pharmacology (12.2)].
If HPA axis suppression is documented, gradually withdraw the drug, reduce the frequency of application, or substitute with a less potent corticosteroid.
Cushing's syndrome and hyperglycemia may also occur due to the systemic effects of the topical corticosteroid. These complications are rare and generally occur after prolonged exposure to excessively large doses, especially of high-potency topical corticosteroids.
Pediatric patients may be more susceptible to systemic toxicity due to their larger skin surface to body mass ratios [see Use in Specific Populations (8.4)].
Allergic contact dermatitis with corticosteroids is usually diagnosed by observing failure to heal rather than noting a clinical exacerbation. Such an observation should be corroborated with appropriate diagnostic patch testing.
The following adverse reactions are discussed in greater detail in other sections of the labeling:
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 clinical practice.
In a controlled clinical trial involving 188 subjects with psoriasis of the scalp, there were no localized scalp adverse reactions reported in the subjects treated with clobetasol propionate foam. In 2 controlled clinical trials with clobetasol propionate foam in 360 subjects with psoriasis of non-scalp regions, localized adverse events that occurred in the subjects treated with clobetasol propionate foam included application site burning (10%), application site dryness (<1%), and other application site reactions (4%).
In larger controlled trials with other clobetasol propionate formulations, the most frequently reported local adverse reactions have included burning, stinging, irritation, pruritus, erythema, folliculitis, cracking and fissuring of the skin, numbness of the fingers, skin atrophy, and telangiectasia (all less than 2%).
Because adverse 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.
Local adverse reactions to topical corticosteroids may include: striae, itching, acneiform eruptions, hypopigmentation, perioral dermatitis, allergic contact dermatitis, secondary infection, hypertrichosis, and miliaria.
Ophthalmic adverse reactions may include: cataracts, glaucoma, increased intraocular pressure, and central serous chorioretinopathy.
There are no available data on clobetasol propionate foam use in pregnant women to inform of a drug-associated risk for adverse developmental outcomes.
Published data report a significantly increased risk of low birthweight with the use of greater than 300 grams of potent or very potent topical corticosteroid during a pregnancy. Advise pregnant women of the potential risk to a fetus and to use clobetasol propionate foam on the smallest area of skin and for the shortest duration possible (see Data). In animal reproduction studies, increased malformations, such as cleft palate and skeletal abnormalities, were observed after subcutaneous administration of clobetasol propionate to pregnant mice and rabbits. No comparison of animal exposure with human exposure was computed.
The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively.
Multiple observational studies found no significant associations between maternal use of topical corticosteroids of any potency and congenital malformations, preterm delivery, or fetal mortality. However, when the dispensed amount of potent or very potent topical corticosteroid exceeded 300 g during the entire pregnancy, use was associated with an increase in low birth weight infants [adjusted RR, 7.74 (95% CI, 1.49 to 40.11)]. In addition, a small cohort study, in which 28 sub-Saharan women using potent topical corticosteroids (27/28 used clobetasol propionate 0.05%) for skin lightening during pregnancy, noted a higher incidence of low birth weight infants in the exposed group. The majority of exposed subjects treated large areas of the body (a mean quantity of 60 g/month (range, 12 to 170 g) over long periods of time.
Embryofetal development studies conducted with clobetasol propionate in mice using the subcutaneous route resulted in fetotoxicity at the highest dose tested (1 mg/kg) and malformations at all dose levels tested down to 0.03 mg/kg. Malformations seen included cleft palate and skeletal abnormalities.
In an embryofetal development study in rabbits, subcutaneous administration of clobetasol propionate resulted in malformations at doses of 0.003 and 0.01 mg/kg. Malformations seen included cleft palate, cranioschisis, and other skeletal abnormalities.
There is no information regarding the presence of clobetasol propionate in breast milk or its effects on the breastfed infant or on milk production.
Systemically administered corticosteroids appear in human milk and can suppress growth, interfere with endogenous corticosteroid production, or cause other untoward effects. It is not known whether topical administration of clobetasol propionate 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 clobetasol propionate foam and any potential adverse effects on the breastfed infant from clobetasol propionate foam or from the underlying maternal condition.
To minimize potential exposure to the breastfed infant via breast milk, use clobetasol propionate foam on the smallest area of skin and for the shortest duration possible while breastfeeding. Advise breastfeeding women not to apply clobetasol propionate foam directly to the nipple and areola to avoid direct infant exposure.
Safety and effectiveness of clobetasol propionate foam in patients younger than 12 years of age have not been established; therefore, use in children younger than 12 years 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 systemic toxicity when they are treated with topical drugs. They are, therefore, also at greater risk of adrenal insufficiency upon the use of topical corticosteroids.
Rare systemic toxicities such as Cushing's syndrome, linear growth retardation, delayed weight gain, and intracranial hypertension have been reported in pediatric patients especially those with prolonged exposure to large doses of high potency topical corticosteroids.
Local adverse reactions including striae have also been reported with use of topical corticosteroids in pediatric patients.
Avoid use of clobetasol propionate foam in the treatment of diaper dermatitis.
Clinical studies of clobetasol propionate foam 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. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range.
Clobetasol propionate foam, 0.05%, is a white thermolabile hydroethanolic aerosol foam containing the active ingredient, clobetasol propionate, USP, a synthetic corticosteroid, for topical use. Clobetasol, an analog of prednisolone, has a high degree of glucocorticoid activity and a slight degree of mineralocorticoid activity.
Clobetasol propionate is 21-chloro-9-fluoro-11β,17-dihydroxy-16β-methylpregna-1,4-diene-3,20-dione 17-propionate, with the empirical formula C25H32CIFO5, a molecular weight of 466.97.
The following is the chemical structure:
Clobetasol propionate is a white to almost white crystalline powder, practically insoluble in water.
Each gram of clobetasol propionate foam contains 0.5 mg clobetasol propionate, USP. The foam also contains cetyl alcohol, citric acid anhydrous, dehydrated alcohol (60%), polysorbate 60, potassium citrate, propylene glycol, purified water, and stearyl alcohol pressurized with a hydrocarbon (propane/butane) propellant.
Corticosteroids play a role in cellular signaling, immune function, inflammation, and protein regulation; however, the precise mechanism of action in corticosteroid-responsive dermatoses is unknown.
In a controlled pharmacokinetic trial, 5 of 13 subjects experienced reversible suppression of the adrenals at any time during the 14 days of therapy with clobetasol propionate foam applied to at least 20% of involved body surface area. Of the 13 subjects studied, 1 of 9 with psoriasis was suppressed after 14 days and all 4 of the subjects with atopic dermatitis had abnormal cortisol levels indicative of adrenal suppression at some time after starting therapy with clobetasol propionate foam (See Table 1 below).

Topical corticosteroids can be absorbed from intact healthy skin. The extent of percutaneous absorption of topical corticosteroids is determined by many factors, including the product formulation and the integrity of the epidermal barrier. Occlusion, inflammation, and/or other disease processes in the skin may also increase percutaneous absorption. Once absorbed through the skin, topical corticosteroids are metabolized, primarily in the liver, and are then excreted by the kidneys. Some corticosteroids and their metabolites are also excreted in the bile.
Long-term animal studies have not been performed to evaluate the carcinogenic potential of clobetasol propionate foam or clobetasol propionate.
In a 90-day repeat-dose toxicity study in rats, topical administration of clobetasol propionate foam at dose concentrations from 0.001% to 0.1% or from 0.03 mg/kg/day to 0.3 mg/kg/day of clobetasol 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 for carcinogenesis.
Clobetasol propionate was nonmutagenic in the Ames test, the mouse lymphoma test, the Saccharomyces cerevisiae gene conversion assay, and the E. coli B WP2 fluctuation test. In the in vivo mouse micronucleus test, a positive finding was observed at 24 hours, but not at 48 hours, following oral administration at a dose of 2,000 mg/kg.
Studies in the rat following subcutaneous administration of clobetasol propionate at dosage levels up to 0.05 mg/kg per day revealed that the females exhibited an increase in the number of resorbed embryos and a decrease in the number of living fetuses at the highest dose.
A well-controlled clinical trial evaluated 188 subjects with moderate to severe scalp psoriasis. Subjects were treated twice daily for 2 weeks with one of 4 treatments: clobetasol propionate foam, vehicle foam, a commercially available clobetasol propionate solution (TEMOVATE® Scalp Application), or vehicle solution. The efficacy of clobetasol propionate foam in treating scalp psoriasis at the end of the 2 weeks' treatment was superior to that of vehicle (foam and solution), and was comparable to that of TEMOVATE Scalp Application (Table 2).

Another well-controlled clinical trial evaluated 279 subjects with mild to moderate plaque-type psoriasis (mean body surface area at baseline was 6.7% with a range from 1% to 20%) of non-scalp regions. Subjects were treated twice daily for 2 weeks with clobetasol propionate foam or vehicle foam. The face and intertriginous areas were excluded from treatment. The efficacy of clobetasol propionate foam in treating non-scalp psoriasis at the end of 2 weeks' treatment was superior to that of vehicle foam (Table 3).

Effects on Endocrine System
Clobetasol propionate foam may cause HPA axis suppression. Advise patients that use of topical corticosteroids, including clobetasol propionate foam, may require periodic evaluation for HPA axis suppression. Topical corticosteroids may have other endocrine effects. Concomitant use of multiple corticosteroid-containing products may increase the total systemic exposure to topical corticosteroids. Patients should inform their physician(s) that they are using clobetasol propionate foam if surgery is contemplated [see Warnings and Precautions (5.1)].
Ophthalmic Adverse Reactions
Advise patients to report any visual symptoms to their healthcare providers [see Warnings and Precautions (5.2)].
Local Adverse Reactions
Report any signs of local adverse reactions to the physician. Advise patients that local reactions and skin atrophy are more likely to occur with occlusive use or prolonged use [see Warnings and Precautions (5.3)].
Advise pregnant women of the potential risk to a fetus and to use clobetasol propionate foam on the smallest area of skin and for the shortest duration possible [see Use in Specific Populations (8.1)].
Advise a woman to use clobetasol propionate foam on the smallest area of skin and for the shortest duration possible while breastfeeding. Advise breastfeeding women not to apply clobetasol propionate foam directly to the nipple and areola to avoid direct infant exposure [see Use in Specific Populations (8.2)].

Important: Clobetasol propionate foam is for use on the skin only. Do not get clobetasol propionate foam in your eyes, mouth or vagina.
How to apply clobetasol propionate foam:
Step 1: Remove the cap and save for further use.
Step 2: Turn the can upside down. Push the button firmly to dispense a small amount of clobetasol propionate foam into the cap of the can, or on your affected skin area. (see Figure A) This amount should be no more than 1½ capfuls, about the size of a golf ball.
Step 4: If you are treating areas with hair, such as the scalp, move any hair away so that the foam can be applied directly to the affected areas. (see Figure D)
Keep the foam away from your eyes, as it will sting and may cause eye problems if there is frequent contact with your eyes. If the foam gets in your eyes, rinse them well with cold water right away. If the stinging continues, contact your healthcare provider right away.
Step 5: Wash your hands after applying clobetasol propionate foam. (see Figure E)
