Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Topical corticosteroid that induces phospholipase A2 inhibitory proteins, collectively called lipocortins, which inhibit the release of arachidonic acid, thereby reducing prostaglandin and leukotriene synthesis, and exerting anti-inflammatory, antipruritic, and vasoconstrictive effects.
AEROSEB-HC (hydrocortisone/iodoquinol) exerts anti-inflammatory, antipruritic, and antifungal actions. Hydrocortisone suppresses inflammatory mediators via glucocorticoid receptor binding, while iodoquinol provides antimicrobial activity against dermatophytes and bacteria.
Relief of inflammatory and pruritic manifestations of corticosteroid-responsive dermatoses (FDA),Off-label: Atopic dermatitis, psoriasis, contact dermatitis, lichen planus, discoid lupus erythematosus
FDA-approved for the treatment of eczematous dermatitis, atopic dermatitis, and other glucocorticoid-responsive dermatoses complicated by fungal or bacterial infections
Topical: Apply a thin film to affected area 3-4 times daily. Dosage strength: 0.5% cream or ointment.
AEROSEB-HC (hydrocortisone/iodoquinol) topical cream: Apply a thin film to affected area twice daily for up to 7 days. Not for ophthalmic or oral use.
Terminal elimination half-life: 1–2 hours for hydrocortisone (active component), prolonged in liver disease or with concurrent CYP3A4 inhibitors.
1.5-2 hours (terminal) after intravenous administration; prolonged in hepatic impairment.
Topically applied; systemic absorption is minimal but can be increased with use on large areas, occlusive dressings, or damaged skin. Absorbed portion is metabolized primarily in the liver via hepatic microsomal enzymes (CYP3A4) and excreted by the kidneys.
Hydrocortisone is primarily hepatic via CYP3A4; iodoquinol is not extensively metabolized, with partial glucuronidation and enterohepatic circulation.
Primarily hepatic metabolism (approximately 95%) followed by renal excretion of inactive metabolites (<5% unchanged). Biliary/fecal excretion is negligible.
Renal (primarily as metabolites; <5% unchanged); fecal (biliary excretion of metabolites).
Hydrocortisone is approximately 90–95% bound to corticosteroid-binding globulin (CBG, transcortin) and albumin.
90-95% (albumin and corticosteroid-binding globulin).
Apparent volume of distribution (Vd) is approximately 0.4–0.6 L/kg, indicating moderate tissue distribution and limited penetration into CNS.
0.4-0.6 L/kg; indicates distribution into total body water and tissues.
Topical: Bioavailability is negligible (<1%) through intact skin; may increase (up to 30%) with damaged skin or occlusive dressings. Rectal: Bioavailability is approximately 10–20% via mucosal absorption, with first-pass metabolism reducing systemic exposure.
Oral: 80-90%; Intramuscular: 100%; Intravenous: 100%.
No adjustment required for topical use; systemic absorption minimal.
No adjustment required for topical application. Systemic absorption is minimal; however, in severe renal impairment (GFR <30 m L/min), use caution due to potential systemic corticosteroid effects.
No adjustment required for topical use; hepatic metabolism negligible.
No specific adjustment for topical use. In Child-Pugh C cirrhosis, consider the risk of systemic corticosteroid accumulation; use with caution.
Children ≥2 years: Apply a thin film to affected area 2-3 times daily. Use lowest potency preparation; avoid prolonged use.
Children >2 years: Apply a thin film to affected area twice daily for up to 7 days. Avoid prolonged use, occlusion, or application to large body surface areas. Safety in children <2 years not established.
Use lowest effective dose; monitor for skin atrophy and systemic effects due to thinner skin and increased percutaneous absorption.
Elderly patients: Use the lowest effective duration and avoid prolonged use due to increased risk of skin atrophy and systemic absorption. Apply sparingly to limited areas.

No known food interactions with topical ALA-CORT.
No clinically significant food interactions are reported for topical hydrocortisone/pramoxine. No dietary restrictions necessary.
FDA Pregnancy Category C. First trimester: No adequate human studies; animal studies show increased risk of cleft palate. Second/third trimester: Risk of intrauterine growth restriction, adrenal suppression in fetus. Avoid prolonged use.
FDA Pregnancy Category C. First trimester: limited data, no increased risk of major malformations identified in small studies. Second and third trimesters: potential for fetal adrenal suppression with prolonged use; avoid high doses and prolonged exposure.
Provides small amounts in breast milk; M/P ratio unknown. At maternal doses up to 80 mg/day, no adverse effects reported in infants. Consider risk-benefit with high doses or prolonged therapy.
Present in breast milk in low concentrations. M/P ratio not determined. Use with caution, especially with high doses or prolonged treatment; risk of infant adrenal suppression theoretical.
Pregnancy-induced pharmacokinetic changes (increased clearance, volume of distribution) may require increased dosing, but clinical response should guide adjustment. Avoid high doses and prolonged use.
No standard dose adjustments required for pregnancy-related pharmacokinetic changes. Use lowest effective dose for shortest duration. Avoid high-dose or prolonged use in pregnancy.
ALA-CORT (hydrocortisone acetate 2.5% and pramoxine HCl 1%) is a topical corticosteroid with anesthetic. Use for short-term relief of pruritus and inflammation in corticosteroid-responsive dermatoses. Avoid prolonged use on intertriginous or occluded areas. Limit to <2 weeks continuous use in adults to avoid skin atrophy. Not recommended for children <2 years.
AEROSEB-HC is a combination aerosol foam containing hydrocortisone acetate 1% and pramoxine hydrochloride 1% for topical use. It is indicated for the relief of inflammatory and pruritic manifestations of corticosteroid-responsive dermatoses, particularly in anogenital areas. The foam formulation enhances penetration and is less messy than ointments. Advise patients to avoid contact with eyes and mucous membranes. Use with caution in patients with skin infections or atrophy. Prolonged use in intertriginous areas may increase risk of local and systemic adverse effects.
