Halcinonide

Trade Names:
Halog
- Ointment 0.1%
- Cream 0.1%
- Solution 0.1%

Mechanism of Action

Pharmacology

Produces anti-inflammatory, antipruritic, and vasoconstrictive effects by an unknown mechanism.

Pharmacokinetics

Absorption

Topical steroids can be absorbed from intact skin. Occlusive dressings, inflammation, and other disease processes in the skin increase percutaneous absorption of topical steroids.

Distribution

Once absorbed, corticosteroids are variably bound to plasma protein.

Metabolism

Corticosteroids are metabolized primarily in the liver.

Elimination

Corticosteroids are excreted primarily by the kidneys and to varying amounts into the bile.

Indications and Usage

Relief of inflammation and pruritus caused by corticosteroid-responsive dermatoses.

Contraindications

Standard considerations.

Dosage and Administration

Topical Apply thin film to affected area bid to tid.

General Advice

• For topical use only. Not for ophthalmic, oral, or intravaginal use.
• Do not apply to face, groin, or axillae unless directed by health care provider.
• Apply medication sparingly but in sufficient quantity to cover affected area(s); rub in gently.
• If using solution on scalp, part the hair, apply a small amount of the medicine on the affected area, rub it in gently, and protect the area from washing and rubbing until the solution dries. Advise patient that they may wash hair as usual but not immediately after applying the medicine.
• Avoid contact with the eyes. If medication does come into contact with the eyes, wash them with large amounts of cool water.

Adverse Reactions

Dermatologic

Acneiform eruptions; allergic contact dermatitis; burning; dryness; folliculitis; hypertrichosis; hypopigmentation; itching; irritation; maceration of the skin; miliaria; perioral dermatitis; secondary infection; skin atrophy; striae.

Precautions

Pregnancy

Category C .

Lactation

Undetermined effect. Exercise caution when topical corticosteroids are administered to a breastfeeding woman.

Children

Safety and efficacy not established for children younger than 12 yr of age. Because of higher ratio of skin surface area to body mass, children are at higher risk than adults for hypothalamic-pituitary-adrenal (HPA) axis suppression and Cushing syndrome when they are treated with topical corticosteroids.

Adrenal suppression

Large doses applied to large surface area or under an occlusive dressing may lead to HPA suppression. If HPA axis suppression is noted, consider drug withdrawal, reduced frequency of application, or substitution of a less potent steroid. Recovery of HPA axis function is generally prompt and complete upon discontinuation of the corticosteroid. Signs and symptoms of withdrawal may require supplemental systemic corticosteroids.

Atrophy

Prolonged use of topical corticosteroids may produce atrophy of the skin and subcutaneous tissues.

Occlusive dressings

Adverse effects are more common when occlusive dressings are used.

Advise patient that instead of using plastic wrap, plastic gloves may be used for the hands, plastic bags for the feet, or a shower cap for the scalp; leave the plastic wrapping or covering in place as long as instructed by health care provider.
