Pharmacologic Category

  • Corticosteroid, Topical


Topical corticosteroids have anti-inflammatory, antipruritic, and vasoconstrictive properties. May depress the formation, release, and activity of endogenous chemical mediators of inflammation (kinins, histamine, liposomal enzymes, prostaglandins) through the induction of phospholipase A2 inhibitory proteins (lipocortins) and sequential inhibition of the release of arachidonic acid. Fluocinolone has low to intermediate range potency (dosage-form dependent).


Dependent on formulation, amount applied, nature of skin at application site; may be increased with inflammation or occlusion




Primarily urine; bile

Use: Labeled Indications

Body oil: Treatment of moderate to severe atopic dermatitis in pediatric patients ≥3 months; treatment of atopic dermatitis in adults

Cream, ointment, topical solution: Relief of inflammatory and pruritic manifestations of corticosteroid-responsive dermatoses

Scalp oil: Treatment of psoriasis of the scalp in adults

Shampoo: Treatment of seborrheic dermatitis of the scalp


Hypersensitivity to fluocinolone or any component of the formulation

Documentation of allergenic cross-reactivity for corticosteroids is limited. However, because of similarities in chemical structure and/or pharmacologic actions, the possibility of cross-sensitivity cannot be ruled out with certainty.

Canadian labeling: Additional contraindications (not in US labeling): Viral (eg, herpes, varicella) lesions of the skin; bacterial or fungal skin infections; parasitic infections; skin manifestations relating to tuberculosis or syphilis; eruptions following vaccinations; application to the eye

Dosing: Adult

Note: Dosage should be based on severity of disease and patient response; use smallest amount for shortest period of time. Therapy should be discontinued when control is achieved.

Atopic dermatitis: Topical: Body oil: Apply thin film to affected area 3 times daily

Corticosteroid-responsive dermatoses: Topical: Cream, ointment, solution: Apply a thin layer to affected area 2 to 4 times daily; may use occlusive dressings to manage psoriasis or recalcitrant conditions

Scalp psoriasis: Topical: Scalp oil: Massage thoroughly into wet or dampened hair/scalp; cover with shower cap. Leave on overnight (or for at least 4 hours). Remove by washing hair with shampoo and rinsing thoroughly.

Seborrheic dermatitis of the scalp: Topical: Shampoo: Apply no more than 1 ounce to scalp once daily; work into lather and allow to remain on scalp for ~5 minutes. Remove from hair and scalp by rinsing thoroughly with water.

Dosing: Geriatric

Refer to adult dosing.

Dosing: Pediatric

Note: Dosage should be based on severity of disease and patient response; use smallest amount for shortest period of time to avoid HPA axis suppression. Therapy should be discontinued when control is achieved.

Atopic dermatitis, moderate to severe:

Derma-Smoothe/FS body oil (0.01%): Infants ≥3 months, Children, and Adolescents: Topical: Moisten skin; apply a thin film to affected area twice daily; do not use for longer than 4 weeks

Derma-Smoothe/FS scalp oil (0.01%): Limited data available: Children ≥2 years and Adolescents: Topical: Apply a thin film to affected area twice daily; do not use longer than 4 weeks

Corticosteroid-responsive dermatoses: Synalar cream (0.025%), ointment (0.025%), topical solution (0.01%): Children and Adolescents: Topical: Apply thin layer 2 to 4 times daily to affected area; may use occlusive dressings to manage psoriasis or recalcitrant conditions


Shampoo: Prior to dispensing, empty the contents of the capsule into the liquid shampoo; shake well.


Topical: Not for oral, ophthalmic, or intravaginal use; do not apply to the face, axillae, or groin unless directed by healthcare provider.

Body oil: Apply the least amount necessary to cover the affected area; do not apply to intertriginous areas.

Cream, ointment, topical solution: Apply sparingly in a thin film; rub in lightly. In hairy sites, the hair should be parted to allow direct contact with the lesion. Occlusive dressings may be helpful in managing psoriasis or recalcitrant conditions, but should not be used if an infection develops.

Shampoo: Shake well before use; do not bandage, wrap, or cover treated scalp area unless directed by healthcare provider.


Body oil, scalp oil, shampoo: Store between 20°C and 25°C (68°F and 77°F); excursions are permitted to 15°C to 30°C (59°F to 86°F). Discard shampoo after 2 months.

Cream, ointment, topical solution: Store between 15°C and 25°C (59°F and 77°F); avoid freezing and excessive heat above 40°C (104°F).

Drug Interactions

Aldesleukin: Corticosteroids may diminish the antineoplastic effect of Aldesleukin. Avoid combination

Adverse Reactions

The following adverse drug reactions and incidences are derived from product labeling unless otherwise specified.

Frequency not defined.

Cardiovascular: Intracranial hypertension (rare)

Central nervous system: Telangiectasia

Dermatologic: Acneiform eruptions, allergic contact dermatitis, atopic dermatitis (secondary), burning, dryness, erythema, folliculitis, irritation, itching, hypertrichosis, hypopigmentation, keratosis pilaris, miliaria, papules, perioral dermatitis, pustules, shiny skin, skin atrophy, striae

Endocrine & metabolic: Cushing's syndrome, HPA axis suppression

Otic: Ear infection

Miscellaneous: Herpes simplex, secondary infection


Concerns related to adverse effects:

• Adrenal suppression: May cause hypercortisolism or suppression of hypothalamic-pituitary-adrenal (HPA) axis, particularly in younger children or in patients receiving high doses for prolonged periods. HPA axis suppression may lead to adrenal crisis.

• Contact dermatitis: Allergic contact dermatitis can occur, it is usually diagnosed by failure to heal rather than clinical exacerbation.

• Kaposi sarcoma: Prolonged treatment with corticosteroids has been associated with the development of Kaposi sarcoma (case reports); if noted, discontinuation of therapy should be considered (Goedert 2002).

• Local effects: Local adverse reactions may occur (eg, skin atrophy, striae, telangiectasias, burning, itching, irritation, dryness, folliculitis, acneiform eruptions, hypopigmentation, perioral dermatitis, allergic contact dermatitis, secondary infection miliaria); may be irreversible. Local adverse reactions are more likely to occur with occlusive and/or prolonged use. If irritation develops, discontinued use and institute appropriate therapy.

• Skin infections: Concomitant skin infections may be present or develop during therapy; discontinue if dermatological infection persists despite appropriate antimicrobial therapy.

• Systemic effects: Topical corticosteroids may be absorbed percutaneously. Absorption of topical corticosteroids may cause manifestations of Cushing syndrome, hyperglycemia, or glycosuria. Absorption is increased by the use of occlusive dressings, application to denuded skin, or application to large surface areas.

Special populations:

• Pediatric: Children may absorb proportionally larger amounts after topical application and may be more prone to systemic effects. HPA axis suppression, intracranial hypertension, and Cushing syndrome have been reported in children receiving topical corticosteroids. Prolonged use may affect growth velocity; growth should be routinely monitored in pediatric patients.

Dosage form specific issues:

• Peanut oil: Derma-Smoothe/FS products may contain peanut oil; use caution in peanut-sensitive individuals.

Other warnings/precautions:

• Appropriate use: Not for oral, ophthalmic, or intravaginal use; do not apply to the face, axillae, groin, or diaper area unless directed by health care provider. Use the least amount needed to cover the affected area; discontinue when control is achieved. If improvement is not seen within 2 weeks, reassess.

• Appropriate use: Shampoo: Has not been proven to be effective in corticosteroid responsive dermatoses other than seborrheic dermatitis of the scalp.

Monitoring Parameters

Growth in pediatric patients; HPA axis suppression (eg, ACTH stimulation test, morning plasma cortisol test, urinary free cortisol test); signs of bacterial or fungal infection

Pregnancy Risk Factor


Pregnancy Considerations

Adverse events have been observed with corticosteroids in animal reproduction studies. In general, the use of topical corticosteroids during pregnancy is not considered to have significant risk; however, intrauterine growth retardation in the infant has been reported (rare). The use of large amounts or for prolonged periods of time should be avoided (Reed 1997).
