1.1 Indication

CLOBEX® Spray, 0.05% is a super-high potent topical corticosteroid formulation indicated for the treatment of moderate to severe plaque psoriasis affecting up to 20% body surface area (BSA) in patients 18 years of age or older.

Patients should be instructed to use CLOBEX® Spray, 0.05% for the minimum amount of time necessary to achieve the desired results see [Dosage and Administration (2)].

Use in patients under 18 years of age is not recommended because safety has not been established and because numerically high rates of HPA axis suppression were seen with other clobetasol propionate topical formulations. [see Use in Specific Populations (8.4) ].

1.2 Limitations of Use

CLOBEX® Spray, 0.05% should not be used on the face, axillae, or groin. CLOBEX® Spray, 0.05% should not be used if there is atrophy at the treatment site. CLOBEX® Spray, 0.05% should not be used in the treatment of rosacea or perioral dermatitis.


CLOBEX® Spray, 0.05% is for topical use only, and not for ophthalmic, oral or intravaginal use.

CLOBEX® Spray, 0.05% should be sprayed directly onto the affected skin areas twice daily and rubbed in gently and completely.

The total dosage should not exceed 50 g (59 mL or 2 fluid ounces) per week because of the potential for the drug to suppress the hypothalamic-pituitary-adrenal (HPA) axis. Do not use more than 26 sprays per application or 52 sprays per day.

CLOBEX® Spray, 0.05% contains a topical corticosteroid; therefore treatment should be limited to 4 weeks. Therapy should be discontinued when control has been achieved. Treatment beyond 2 weeks should be limited to localized lesions of moderate to severe plaque psoriasis that have not sufficiently improved after the initial 2 weeks of treatment with CLOBEX® Spray, 0.05%. If no improvement is seen within 2 weeks, reassessment of diagnosis may be necessary. Before prescribing for more than 2 weeks, any additional benefits of extending treatment to 4 weeks should be weighed against the risk of HPA axis suppression.

Unless directed by physician, CLOBEX® Spray, 0.05% should not be used with occlusive dressings.


Spray, 0.05% w/w. Each gram of CLOBEX® Spray, 0.05% contains 0.5 mg of clobetasol propionate in a clear, colorless liquid.




5.1 Effects on the Endocrine System

Clobetasol propionate is a highly potent topical corticosteroid that has been shown to suppress the HPA axis at the lowest doses tested.

Systemic absorption of topical corticosteroids can produce reversible hypothalamic-pituitary-adrenal (HPA) axis suppression with the potential for clinical glucocorticosteroid insufficiency. This may occur during treatment or upon withdrawal of the topical corticosteroid.

In studies evaluating the potential for hypothalamic-pituitary-adrenal (HPA) axis suppression, using the Cosyntropin Stimulation Test, CLOBEX® Spray, 0.05% demonstrated rates of suppression that were comparable after 2 and 4 weeks of twice-daily use (19% and 15-20%, respectively), in adult patients with moderate to severe plaque psoriasis (≥ 20% BSA). In these studies, HPA axis suppression was defined as serum cortisol level ≤18 μg/dL 30-min post cosyntropin stimulation [see Clinical Pharmacology (12)].

Because of the potential for systemic absorption, use of topical corticosteroids may require that patients be periodically evaluated for HPA axis suppression. Factors that predispose a patient using a topical corticosteroid to HPA axis suppression include the use of more potent steroids, use over large surface areas, use over prolonged periods, use under occlusion, use on an altered skin barrier, and use in patients with liver failure.

An ACTH stimulation test may be helpful in evaluating patients for HPA axis suppression. If HPA axis suppression is documented, an attempt should be made to gradually withdraw the drug, to reduce the frequency of application, or to 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.

Cushing’s syndrome, hyperglycemia, and unmasking of latent diabetes mellitus can also result from systemic absorption of topical corticosteroids.

Use of more than one corticosteroid-containing product at the same time may increase the total systemic corticosteroid exposure.

Pediatric patients may be more susceptible to systemic toxicity from use of topical corticosteroids [see Use in Specific Populations (8.4)].

5.2 Ophthalmic Adverse Reactions

Use of topical corticosteroids, including CLOBEX Spray, may increase the risks of glaucoma and posterior subcapsular cataract. Glaucoma and cataracts have been reported in postmarketing experience with the use of topical corticosteroid products, including topical clobetasol products [see Adverse Reactions (6.2)].
Avoid contact of CLOBEX Spray with eyes. Advise patients to report any visual symptoms and consider referral to an ophthalmologist for evaluation.

5.3 Local Adverse Reactions with Topical Corticosteroids.

The following additional local adverse reactions have been reported with topical corticosteroids. They may occur more frequently with the use of occlusive dressings and higher potency corticosteroids, including clobetasol propionate. These reactions are listed in an approximate decreasing order of occurrence: folliculitis, acneiform eruptions, hypopigmentation, perioral dermatitis, allergic contact dermatitis, secondary infection, striae and miliaria.

5.4 Allergic Contact Dermatitis

Allergic contact dermatitis to any component of topical corticosteroids is usually diagnosed by a failure to heal rather than a clinical exacerbation. Clinical diagnosis of allergic contact dermatitis can be confirmed by patch testing.

5.5 Concomitant Skin Infections

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, use of CLOBEX® Spray, 0.05% should be discontinued until the infection has been adequately controlled.

5.6 Flammable Contents

CLOBEX® Spray, 0.05% is flammable; keep away from heat or flame.


6.1 Clinical Trials Experience

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 controlled, clinical trials with CLOBEX® Spray, 0.05%, the most common adverse reaction was burning at the site of application [40% of subjects treated with CLOBEX® Spray, 0.05% and 47% of subjects treated with Spray Vehicle]. Other commonly reported adverse reactions for CLOBEX® Spray, 0.05% and Spray Vehicle, respectively, are noted in Table 1.

Most local adverse reactions were rated as mild to moderate and they are not affected by age, race or gender.

Systemic absorption of topical corticosteroids has produced hypothalamic-pituitary-adrenal (HPA) axis suppression, manifestations of Cushing’s syndrome, hyperglycemia, and glucosuria in some patients.
