Clobex lotion for moderate to severe plaque psoriasis and atopic dermatitis in adults

Clobex lotion contains clobetasol propionate, a very potent synthetic corticosteroid used on the skin to relieve inflammation and itching. It is formulated for topical use in adults to treat certain corticosteroid-responsive skin conditions when a strong anti-inflammatory effect is needed.

Clobex lotion is prescribed for adults 18 years and older to reduce inflammation and itching associated with corticosteroid-responsive dermatoses, specifically:

• Moderate to severe plaque psoriasis with localized lesions involving less than 10% of body surface area
• Moderate to severe atopic dermatitis

Treatment duration is limited: up to 2 consecutive weeks for most dermatoses, and up to 4 weeks total (with an additional 2 weeks) for localized moderate to severe plaque psoriasis if improvement is insufficient after the initial treatment.

clobetasol propionate 0.05%

Clobex lotion’s active ingredient, clobetasol propionate, is a super-high potency corticosteroid. It works by reducing inflammation and itching through mechanisms believed to involve the induction of lipocortin proteins that inhibit the enzyme phospholipase A2. This reduces the production of inflammatory mediators like prostaglandins and leukotrienes, ultimately decreasing skin inflammation and pruritus.

Apply Clobex lotion twice daily to affected skin areas, gently rubbing in completely.

• Treatment duration should not exceed 2 consecutive weeks for corticosteroid-responsive dermatoses.
• For moderate to severe plaque psoriasis with localized lesions (less than 10% body surface area) not improved after 2 weeks, treatment may be extended up to 2 additional weeks.
• The total amount used should not exceed 50 grams (50 mL or 1.75 fl. oz.) per week to reduce the risk of systemic corticosteroid effects.
• Discontinue use once control is achieved or if no improvement is seen after 2 weeks, and consult a physician for reassessment.
• Use in children under 18 years of age is not recommended due to risk of adrenal suppression.
• Do not use occlusive dressings unless prescribed by a doctor.

Clobex lotion is contraindicated in patients with known hypersensitivity to clobetasol propionate, other corticosteroids, or any ingredient in the formulation.

Important risks and precautions:

• Clobex is a highly potent corticosteroid and can cause hypothalamic-pituitary-adrenal (HPA) axis suppression, leading to adrenal insufficiency if absorbed in significant amounts.
• Systemic absorption risk increases with prolonged use, application over large areas, use under occlusion, or broken skin.
• Patients should be monitored for signs of adrenal suppression during therapy, especially if large amounts or extended treatment periods are used.
• Reactions such as burning, stinging, irritation, dryness, skin thinning, and widening of blood vessels (telangiectasia) may occur.
• Avoid use on the face, groin, or underarms; do not apply to rosacea or perioral dermatitis.
• Do not use in pediatric patients under 18 due to higher susceptibility to HPA axis suppression and other side effects like growth retardation.
• Not recommended for use longer than 2 weeks (except in limited psoriasis cases with additional 2 weeks).
• If irritation or allergic contact dermatitis develops, discontinue use immediately.
• Patients should inform their healthcare provider if planning surgery or if acutely ill or injured, as intermittent HPA suppression may increase morbidity.

Common side effects reported with Clobex lotion include:

• Mild burning or stinging at application site
• Skin dryness and irritation
• Pruritus (itching)
• Skin atrophy (thinning) in about 4.2% of patients
• Telangiectasia (dilated surface blood vessels) in about 3.2% of patients

Other less frequent reactions may include folliculitis, acne-like eruptions, hypopigmentation, perioral dermatitis, allergic contact dermatitis, secondary infection, striae, and miliaria, particularly with occlusive use or prolonged therapy.

Use caution when combining Clobex lotion with other topical or systemic corticosteroids due to additive risk of systemic corticosteroid side effects. Avoid occlusive dressings unless specifically directed by a healthcare provider as they can increase absorption and side effects.

Pregnancy: Animal studies show clobetasol propionate is teratogenic and fetotoxic at doses comparable to human topical use. There are no adequate controlled studies in pregnant women. Use only if the potential benefit justifies the potential risk to the fetus.

Breastfeeding: It is unknown whether topical clobetasol propionate is excreted in human milk. Exercise caution when administering to nursing women.

Excessive application can result in systemic corticosteroid effects including HPA axis suppression. Management includes monitoring adrenal function and providing supplemental systemic corticosteroids if indicated.

Store Clobex lotion at controlled room temperature between 68°F and 77°F (20°C to 25°C). Protect from freezing.
