What Is Halobetasol Propionate Used For?

INDICATIONS AND USAGE Halobetasol propionate ointment, 0.05% is a super-high potency corticosteroid indictated for the relief of the inflammatory and pruritic manifestations of corticosteroid-responsive dermatoses. Treatment beyond two consecutive weeks is not recommended, and the total dosage should not exceed 50 g/week because of the potential for the drug to suppress the hypothalamic-pituitary-adrenal (HPA) axis.

Dosage and Administration

DOSAGE AND ADMINISTRATION Apply a thin layer of halobetasol propionate ointment, 0.05% to the affected skin once or twice daily, as directed by your physician, and rub in gently and completely. Halobetasol propionate ointment, 0.05% is a high potency topical corticosteroid; therefore, treatment should be limited to two weeks, and amounts greater than 50g/wk should not be used. As with other corticosteroids, therapy should be discontinued when control is achieved. If no improvement is seen within 2 weeks, reassessment of diagnosis may be necessary. Halobetasol propionate ointment, 0.05% should not be used with occlusive dressings.

Side Effects (Adverse Reactions)

ADVERSE REACTIONS In controlled clinical trials, the most frequent adverse events reported for halobetasol propionate ointment, 0.05% included stinging or burning in 1.6% of the patients. Less frequently reported adverse reactions were pustulation, erythema, skin atrophy, leukoderma, acne, itching, secondary infection, telangiectasia, urticara, dry skin, miliaria, paresthesia, and rash. The following additional local adverse reactions are reported infrequently with topical corticosteroids, and they may occur more frequently with high potency corticosteroids, such as halobetasol propionate ointment, 0.05%. These reactions are listed in an approximate decreasing order of occurrence: folliculitis, hypertrichosis, acneiform eruptions, hypopigmentation, perioral dermatitis, allergic contact dermatitis, secondary infection, striae and miliaria.

Contraindications

CONTRAINDICATIONS Halobetasol propionate ointment, 0.05% is contraindicated in those patients with a history of hypersensitivity to any of the components of the preparation.

Pregnancy and Breastfeeding

Pregnancy Teratogenic effects: Pregnancy Catergory C: Corticosteroids have been shown to be teratogenic in laboratory animals when administered systemically at relatively low dosage levels. Some corticosteroids have been shown to be teratogenic after dermal application in laboratory animals. Halobetasol propionate has been shown to be teratogenic in SPF rats and chinchilla-type rabbits when given systemically during gestation at doses of 0.04 to 0.1 mg/kg in rats and 0.01 mg/kg in rabbits. These doses are approximately 13, 33 and 3 times, respectively, the human topical dose of halobetasol propionate ointment, 0.05%. Halobetasol propionate was embryotoxic in rabbits but not in rats. Cleft palate was observed in both rats and rabbits. Omphalocele was seen in rats, but not in rabbits. There are no adequate and well-controlled studies of teratogenic potential of halobetasol propionate in pregnant women. Halobetasol propionate ointment, 0.05% should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

Nursing Mothers Systemically administered corticosteroids appear in human milk and could suppress growth, interfere with endogenous corticosteroid production, or cause other untoward effects. It is not known whether topical administration of corticosteroids could result in sufficient systemic absorption to produce detectable quantities in human milk. Because many drugs are excreted in human milk, caution should be exercised when halobetasol propionate ointment, 0.05% is administered to a nursing woman.

Overdosage

OVERDOSAGE Topically applied halobetasol propionate ointment, 0.05% can be absorbed in sufficient amounts to produce systemic effects (see PRECAUTIONS ).
