Max: 50 grams/week; do not use for longer than 2 weeks; do not use with occlusive dressings. Halobetasol has been used short-term off-label for selected conditions, such as localized eczema/atopic dermatitis. In a pediatric study (age 5 to 15 years), halobetasol cream was applied in a thin layer to the affected area(s) once daily in the morning, and halobetasol ointment was applied in a thin layer once daily in the evening for 14 days. Efficacy was documented in more than 90% with no systemic adverse events.

    For the treatment of moderate to severe chronic plaque-type psoriasis.
    Topical dosage (cream or ointment)
    Adults

    Apply a thin layer of cream or ointment to the affected skin area(s) once or twice daily; rub in gently and completely. Max: 50 grams/week; do not use for longer than 2 consecutive weeks. Discontinue when control is achieved. If no improvement in 2 weeks, reassess. Do not use with occlusive dressings.

    Children† and Adolescents† 5 years and older

    Safety and efficacy have not been established; however, off-label use for localized plaque psoriasis is reported. Apply topically twice daily to the affected skin area(s). Max: 50 grams/week; do not use for longer than 2 weeks; do not use with occlusive dressings. In a pediatric study (age 5 to 15 years), halobetasol cream was applied in a thin layer to the affected area(s) once daily in the morning, and halobetasol ointment was applied in a thin layer once daily in the evening for 14 days. Occlusion was not used. Success was documented in more than 90% with no systemic adverse events.

    Topical dosage (lotion)
    Adults

    Apply a thin layer to the affected skin area(s) twice daily. Limit treatment to 2 consecutive weeks. Max: 50 grams/week. Discontinue when control is achieved. If no improvement in 2 weeks, reassess.

    Topical dosage (foam)
    Adults

    Apply a thin layer topically to the affected skin area(s) twice daily for up to 2 weeks. Limit treatment to 2 consecutive weeks. Max: 50 grams/week. Discontinue when control is achieved. If no improvement in 2 weeks, reassess.

    For the treatment of cutaneous T-cell lymphoma (CTCL)† (also known as mycosis fungoides†).
    Topical dosage (cream or ointment)
    Adults and Adolescents 14 years and older

    Apply thoroughly and vigorously only to the lesioned skin areas twice daily. One study (n = 79) demonstrated complete remission in 88% of patients (age 14 to 84 years) with patch-stage mycosis fungoides treated with corticosteroids. Treatment was continued of 2 to 3 months before determining efficacy, and was continued for 1 month following clearing. The very high potency compounds studied, including halobetasol, were most effective. Thirteen percent of patients experienced reversible serum cortisol depression, but none had clinical symptoms. One patient discontinued therapy due to skin atrophy.

    Specific guidelines for dosage adjustments in renal impairment are not available; it appears that no dosage adjustments are needed.

    ADMINISTRATION

    Topical Administration

    For topical dermatologic use only. Not for ophthalmic, oral, or vaginal use.
    Avoid contact with the eyes. Halobetasol is not recommended for use on the face, scalp, groin, or in the axillae.

    Cream/Ointment/Lotion Formulations

    Restrict application to the active lesions or affected areas and try to avoid normal surrounding skin.
    The amount of cream, lotion, or ointment needed to cover a certain area can be calculated. A 1 gram application of cream covers 100 cm2 of skin. The entire skin surface of the average size adult will be covered by 30 grams of topical steroid cream.
    Do not use cream or ointment with occlusive dressings. The lotion should only be used with occlusion under prescription order.
    Very high potency corticosteroids such as halobetasol are not recommended for use in the diaper area of infants. If halobetasol is medically necessary, do not use tight fitting diapers or plastic pants on children, as these garments may constitute occlusive dressings.
    Apply sparingly in a thin film and rub gently into affected area. Use gloves if required by universal precautions.
    Wash hands after application. Patients should wash their hands after application unless the product is being used to treat the hands.

    Other Topical Formulations

    Topical foam
    Prior to first application, remove cap and break the small tab at the base of the actuator; do not break the hinge on the actuator.
    Shake well prior to each use.
    Invert the can and dispense a small amount of the foam into the palm of the hand.
    Apply a thin layer to the affected area and rub in gently until foam disappears. Use gloves if required by universal precautions.
    Wash hands after application. Patients should wash their hands after application unless the foam is being used to treat the hands.
    This product is flammable; avoid heat, flame, or smoking during and immediately following application of the foam.

    CONTRAINDICATIONS / PRECAUTIONS

    Corticosteroid hypersensitivity, occlusive dressing

    Halobetasol is contraindicated in any patient with a history of hypersensitivity to any ingredients in the preparation; use with caution in patients with a history of severe corticosteroid hypersensitivity reactions to other corticosteroids. Halobetasol cream and ointment should not be used with an occlusive dressing. Do not use the foam or lotion with occlusive dressings unless directed by a physician.

    Cushing's syndrome, diabetes mellitus, hypothalamic-pituitary-adrenal (HPA) suppression, skin abrasion

    Systemic absorption of topical corticosteroids has produced reversible hypothalamic-pituitary-adrenal (HPA) suppression, manifestations of Cushing's syndrome, hyperglycemia, and glucosuria in some patients. Conditions which increase systemic absorption include application of very high-potency corticosteroids (such as halobetasol), use over large surface areas, prolonged use, use in areas where the epidermal barrier is disrupted (i.e., skin abrasion), and the use of an occlusive dressing. Patients receiving large doses of a potent topical corticosteroid applied to a large surface area or under an occlusive dressing should be evaluated periodically for evidence of HPA axis suppression using ACTH stimulation, AM plasma cortisol and urinary free-cortisol tests. If HPA axis suppression is noted, an attempt should be made to withdraw the drug, to reduce the frequency of application, or to substitute a less potent corticosteroid. HPA axis suppression has been reported in psoriasis patients using 7 grams/day of halobetasol for 1 week of treatment. In one study, 5 out of 20 (25%) adults receiving treatment with halobetasol lotion (mean dose of 3.5 grams applied twice daily for 2 weeks) developed HPA axis suppression. In this study, suppression was defined as serum cortisol concentration less than or equal to 18 mcg/dL, read 30 minutes after stimulation with cosyntropin. Recovery of HPA axis function is generally prompt and complete upon discontinuation of the topical corticosteroid. Infrequently, signs and symptoms of corticosteroid withdrawal may occur, requiring supplemental systemic corticosteroids. Due to the potential for glucose alterations, halobetasol should be used cautiously in patients with diabetes mellitus.

    Children, growth inhibition, increased intracranial pressure, infants, neonates

    Use halobetasol with caution in children. Administration of halobetasol cream and ointment to pediatric patients 12 years and older should be limited to the least amount compatible with an effective therapeutic regimen. The safety and efficacy of halobetasol cream and ointment in neonates, infants, and children less than 12 years of age have not been established, although off-label use has been reported in pediatric patients 5 years and older. The safety and effectiveness of halobetasol lotion or foam in patients younger than 18 years of age has not been established. Children may absorb proportionally larger amounts of topical corticosteroids due to a larger skin surface area to body weight ratio, and therefore are more susceptible to developing systemic toxicity, especially with very-high-potency products. Hypothalamic-pituitary-adrenal (HPA) axis suppression, Cushing's syndrome, growth inhibition (linear growth retardation and delayed weight gain), and increased intracranial pressure have been reported in children receiving topical corticosteroids. If children are being treated with topical corticosteroids in the diaper area, tight-fitting diapers or plastic pants should be avoided as these garments may act as an occlusive dressing and increase systemic absorption of the drug.

    Pregnancy

    Halobetasol should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Topical corticosteroids, including halobetasol, should not be used in large amounts, on large areas, or for prolonged periods of time in pregnant women. Guidelines recommend mild to moderate potency agents over potent corticosteroids, which should be used in short durations. Fetal growth restriction and a significantly increased risk of low birthweight has been reported with use of potent or very potent topical corticosteroids during the third trimester, particularly when using more than 300 grams. There are no adequate and well-controlled studies of teratogenic effects from topical application of halobetasol in pregnant women. Corticosteroids have been shown to be teratogenic after dermal, oral, and subcutaneous administration in animal studies. Halobetasol has greater potency, and thus greater teratogenic potential, than other topical corticosteroids. After systemic halobetasol propionate administration to pregnant mice and rabbits, increased malformations, such as cleft palate and skeletal abnormalities, were observed.

    Breast-feeding

    It is not known whether topical administration of halobetasol could result in sufficient systemic absorption to produce detectable quantities in breast milk. However, most dermatologists stress that topical corticosteroids can be safely used during lactation and breast-feeding. If applied topically, care should be used to ensure the infant will not come into direct contact with the area of application, such as the breast. Increased blood pressure has been reported in an infant whose mother applied a high potency topical corticosteroid ointment directly to the nipples. Consider the benefits of breast-feeding, the risk of potential infant drug exposure, and the risk of an untreated or inadequately treated condition.

    Fungal infection, herpes infection, infection, measles, tuberculosis, varicella, viral infection

    The normal inflammatory response to local infections can be masked by halobetasol. Application of topical corticosteroids to areas of infection, including tuberculosis of the skin, dermatologic fungal infection, and cutaneous or systemic viral infection (i.e., measles or varicella), should be initiated or continued only if the appropriate antiinfective treatment is instituted. Herpes infection may be transmitted to other sites, including the eye. If the infection does not respond to the antimicrobial therapy, the concurrent use of the topical corticosteroid should be discontinued until the infection is controlled. Topical corticosteroids may delay the healing of non-infected wounds, such as venous stasis ulcers.

    Acne rosacea, acne vulgaris, cataracts, glaucoma, ocular exposure, perioral dermatitis

    As with other potent fluorinated topical corticosteroids, halobetasol should not be used to treat acne vulgaris, acne rosacea, or perioral dermatitis. Halobetasol may aggravate these conditions. Halobetasol preparations should not be applied to the face, groin, or axillae. Care should be taken to avoid use around the eyes; ocular exposure should be avoided. Visual impairment and ocular hypertension have been reported with ocular exposure or facial application of other high potency topical corticosteroids. High potency corticosteroids have been noted to promote progression of cataracts. Preexisting glaucoma may be aggravated if halobetasol is used in the periorbital area.

    Geriatric, peripheral vascular disease, skin atrophy

    Topical corticosteroids, including halobetasol, should be used for brief periods or under close medical supervision in patients with evidence of pre-existing skin atrophy. Geriatric patients may be more likely to have preexisting skin atrophy secondary to aging. Purpura and skin lacerations that may raise the skin and subcutaneous tissue from deep fascia may be more likely to occur with the use of topical corticosteroids in geriatric patients. Use halobetasol preparations cautiously in patients with markedly impaired circulation or peripheral vascular disease due to the potential for skin ulcer. Use of lower potency topical corticosteroids also may be necessary in some patients.

    Tobacco smoking

    The foam formulation of halobetasol is flammable. Avoid use of the foam near a fire or flame, including tobacco smoking, during or immediately after application.[63282]

    PREGNANCY AND LACTATION

    Pregnancy

    Halobetasol should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Topical corticosteroids, including halobetasol, should not be used in large amounts, on large areas, or for prolonged periods of time in pregnant women. Guidelines recommend mild to moderate potency agents over potent corticosteroids, which should be used in short durations. Fetal growth restriction and a significantly increased risk of low birthweight has been reported with use of potent or very potent topical corticosteroids during the third trimester, particularly when using more than 300 grams. There are no adequate and well-controlled studies of teratogenic effects from topical application of halobetasol in pregnant women. Corticosteroids have been shown to be teratogenic after dermal, oral, and subcutaneous administration in animal studies. Halobetasol has greater potency, and thus greater teratogenic potential, than other topical corticosteroids. After systemic halobetasol propionate administration to pregnant mice and rabbits, increased malformations, such as cleft palate and skeletal abnormalities, were observed.

    It is not known whether topical administration of halobetasol could result in sufficient systemic absorption to produce detectable quantities in breast milk. However, most dermatologists stress that topical corticosteroids can be safely used during lactation and breast-feeding. If applied topically, care should be used to ensure the infant will not come into direct contact with the area of application, such as the breast. Increased blood pressure has been reported in an infant whose mother applied a high potency topical corticosteroid ointment directly to the nipples. Consider the benefits of breast-feeding, the risk of potential infant drug exposure, and the risk of an untreated or inadequately treated condition.

    MECHANISM OF ACTION

    Topical corticosteroids exhibit anti-inflammatory, antipruritic, and vasoconstrictive properties. At the cellular level, corticosteroids induce peptides called lipocortins. Lipocortins antagonize phospholipase A2, an enzyme which causes the breakdown of leukocyte lysosomal membranes to release arachidonic acid. This action decreases the subsequent formation and release of endogenous inflammatory mediators including prostaglandins, kinins, histamine, liposomal enzymes and the complement system. Early anti-inflammatory effects of topical corticosteroids include the inhibition of macrophage and leukocyte movement and activity in the inflamed area by reversing vascular dilation and permeability. Later inflammatory processes such as capillary production, collagen deposition, keloid (scar) formation also are inhibited by corticosteroids. Clinically, these actions correspond to decreased edema, erythema, pruritus, plaque formation and scaling of the affected skin.

    PHARMACOKINETICS

    Halobetasol is administered topically to the skin; a variety of formulations are available for topical use. Once in the systemic circulation, halobetasol is metabolized in the liver, but systemic metabolism has not been fully quantified. Excretion of halobetasol and its metabolites occurs via the urine and bile.

    Topical Route

    The extent of percutaneous absorption of the topical corticosteroids is dependent on many factors, including the vehicle, integrity of the epidermis, and use of occlusive dressing. Absorption after topical application of halobetasol is increased in areas that have skin damage, inflammation, or occlusion, or in areas where the stratum corneum is thin such as the eyelids, genitalia, axillae, and face. The use of occlusive dressings with the application of halobetasol enhances penetration into the skin, and may increase the chance of systemic absorption. Ointments have a hydrating effect, are lipophilic, and enhance the penetration of halobetasol into the skin. Anti-inflammatory effects are usually not seen for hours after halobetasol application, since the mechanism of action requires alterations in synthesis of proteins. Because halobetasol is fluorinated and also contains a substituted 17-hydroxyl group, it is not metabolized in the skin. Repeated application results in a cumulative depot effect in the skin, which may lead to a prolonged duration of action and increased systemic absorption.
    cream and ointment: Human and animal studies indicate that less than 6% of the applied dose of halobetasol propionate enters the circulation within 96 hours following topical administration.
    lotion: Based on data obtained from 12 adult administered halobetasol lotion, the drug was detectable in the plasma in all study subjects, and steady-state concentrations were achieved by treatment day 8. The median time to reach maximum concentration (Tmax) is 3 hours (range, 0 to 6 hours).
    topical foam: In a study of 23 adults with moderate to severe plaque psoriasis receiving twice daily halobetasol foam for 14 days (mean dose of 7.4 grams/day), steady-state was achieved by day 14 with a mean Cmax of 199.7 +/- 217.3 pg/mL and corresponding median time to maximum concentration (Tmax) of 1 hour (range 0 to 12 hours); mean AUC was 1,434 +/- 1,310.6 pg/hour/mL.
