What is Clobetasol (Clobetasol, a topical corticosteroid) used for?

From the Guidelines

Clobetasol is a highly effective treatment for various inflammatory skin conditions, including psoriasis, and should be used as a first-line treatment for up to two weeks, with a maximum dose of 50 grams per week, as supported by the guidelines of care for the management of psoriasis and psoriatic arthritis 1.

Key Points to Consider

• Clobetasol is a high-potency topical corticosteroid, classified as a class I steroid, with efficacy rates ranging from 58% to 92% for the treatment of psoriasis 1.
• The optimal duration of use for clobetasol is 2 to 4 weeks, with increased risk of cutaneous side effects and systemic absorption if used continuously for longer periods of time 1.
• When using clobetasol, it is recommended to apply a thin layer to affected areas once or twice daily, avoiding the face, groin, and underarms unless specifically directed by a healthcare provider 1.
• Clobetasol works by reducing inflammation, itching, and redness by suppressing the immune response in the skin, with potential side effects including skin thinning, stretch marks, easy bruising, and increased risk of infection with prolonged use 1.

Tapering and Maintenance

• When discontinuing clobetasol after prolonged use, it is essential to taper the medication rather than stopping abruptly to prevent rebound effects 1.
• For maintenance, a tapering schedule with dose adaptation can be used, with options including daily treatment in the first month, treatment every 2 days in the second month, and treatment twice per week in the third month 1.

Special Considerations

• Clobetasol can be used to treat other inflammatory skin conditions, such as lichen sclerosus, with a recommended regimen of once-daily application for 4 weeks, followed by alternate nights for 4 weeks, and then twice weekly for a further 4 weeks 1.
• Long-term use of clobetasol has been shown to be safe and effective in some studies, with most patients requiring 30-60 grams of clobetasol propionate 0.05% ointment annually 1.

From the FDA Drug Label

Clobetasol propionate topical solution, USP is indicated for short-term topical treatment of inflammatory and pruritic manifestations of moderate to severe corticosteroid-responsive dermatoses of the scalp. Treatment beyond 2 consecutive weeks is not recommended, and the total dosage should not exceed 50 mL/week because of the potential for the drug to suppress the HPA axis. Clobetasol propionate is a highly potent topical corticosteroid that has been shown to suppress the HPA axis at doses as low as 2 g (of ointment) per day. Systemic absorption of topical corticosteroids has resulted in reversible HPA axis suppression, manifestations of Cushing's syndrome, hyperglycemia, and glucosuria in some patients.

• Indications and Usage: Clobetasol propionate topical solution is used for short-term treatment of inflammatory and pruritic manifestations of moderate to severe corticosteroid-responsive dermatoses of the scalp.
• Dosage and Administration: Treatment should not be extended beyond 2 consecutive weeks, and the total dosage should not exceed 50 mL/week.
• HPA Axis Suppression: Clobetasol propionate can suppress the HPA axis, and systemic absorption has resulted in reversible HPA axis suppression, Cushing's syndrome, hyperglycemia, and glucosuria in some patients 2 2 2.

From the Research

Clobetasol Overview

• Clobetasol propionate is the most potent of all topical steroids, used in the treatment of various skin diseases such as atopic dermatitis, psoriasis, and vulvar lichen sclerosus 3.
• It exerts anti-inflammatory, immunosuppressive, and antimitotic effects, influencing the growth, differentiation, and function of various cells and inhibiting cytokine production 3.

Therapeutic Uses

• Clobetasol propionate is effective in the treatment of psoriasis, eczema, and other dermatoses, with a preventive effect reported in the treatment of vulvar lichen sclerosus 3, 4.
• It is also used in the treatment of dry, scaly, corticosteroid-responsive dermatoses, with an emollient added to the steroid helping to restore the normal moisturizing process of the skin 4.

Formulations and Efficacy

• Various formulations of clobetasol propionate are available, including creams, ointments, and sprays, with the choice of formulation affecting patient compliance and efficacy 3, 5, 6.
• Clobetasol propionate 0.05% cream and spray have been shown to be effective in the treatment of psoriasis and other dermatoses, with high response rates and significant improvements in disease severity scores 5, 6.

Safety and Side Effects

• Clobetasol propionate can cause local and systemic side effects, including skin atrophy and hypothalamic-pituitary-adrenal axis suppression, highlighting the need for careful patient instruction and monitoring 3.
• Adverse events such as burning, irritation, and dryness have been reported with the use of clobetasol propionate sprays, although these are generally similar to those seen with other topical corticosteroids 6.
