Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
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.
Selective beta-2 adrenergic receptor agonist; relaxes bronchial smooth muscle by increasing intracellular cyclic AMP.
FDA-approved for the treatment of eczematous dermatitis, atopic dermatitis, and other glucocorticoid-responsive dermatoses complicated by fungal or bacterial infections
Treatment or prevention of bronchospasm in patients with reversible obstructive airway disease,Prevention of exercise-induced bronchospasm
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.
Two inhalations (90 mcg each) via oral inhalation every 4-6 hours as needed; for prevention of exercise-induced bronchospasm, two inhalations 15-30 minutes before exercise.
1.5-2 hours (terminal) after intravenous administration; prolonged in hepatic impairment.
Terminal elimination half-life: 3.8 to 5 hours; clinically, this supports a dosing interval of every 4-6 hours as needed for symptom relief.
Hydrocortisone is primarily hepatic via CYP3A4; iodoquinol is not extensively metabolized, with partial glucuronidation and enterohepatic circulation.
Primarily metabolized by catechol-O-methyltransferase (COMT) and to a lesser extent by sulfation; not metabolized by CYP450 enzymes.
Renal (primarily as metabolites; <5% unchanged); fecal (biliary excretion of metabolites).
Renal: approximately 72% as unchanged drug and metabolites; fecal: approximately 10%; biliary: minimal.
90-95% (albumin and corticosteroid-binding globulin).
Approximately 94% bound to human serum albumin.
0.4-0.6 L/kg; indicates distribution into total body water and tissues.
Vd: 1.9 to 2.7 L/kg; this large Vd indicates extensive distribution into tissues, including lung tissue.
Oral: 80-90%; Intramuscular: 100%; Intravenous: 100%.
Inhalation: approximately 10-20% of the administered dose reaches the lungs; the remainder is swallowed and undergoes first-pass metabolism resulting in negligible oral bioavailability.
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 dosage adjustment required for renal impairment.
No specific adjustment for topical use. In Child-Pugh C cirrhosis, consider the risk of systemic corticosteroid accumulation; use with caution.
No dosage adjustment required for hepatic impairment.
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.
Children 4-11 years: Two inhalations (90 mcg each) via oral inhalation every 4-6 hours as needed; for exercise-induced bronchospasm, two inhalations 15-30 minutes before exercise. Children <4 years: Safety and efficacy not established.
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 specific dose adjustment; use with caution due to potential for decreased renal function and increased sensitivity to beta-agonists.
None
Not applicable; no black box warning.
Prolonged use may lead to systemic corticosteroid effects, including HPA axis suppression, Cushing's syndrome, and hyperglycemia.,Risk of secondary infection due to immunosuppression.,Local adverse reactions such as skin atrophy, striae, and perioral dermatitis.,Avoid use in diaper area or under occlusive dressings.
Paradoxical bronchospasm may occur,Cardiovascular effects: increased heart rate, blood pressure, or ECG changes,Immediate hypersensitivity reactions,Potentially severe hypokalemia,May exacerbate diabetes and ketoacidosis
Hypersensitivity to any component (hydrocortisone, iodoquinol, or sulfites).,Viral or fungal infections without appropriate antimicrobial coverage.,Immunocompromised patients (systemic use relative).,Pregnancy (category C, use only if benefit outweighs risk).
Hypersensitivity to albuterol or any component of the formulation
No clinically significant food interactions are reported for topical hydrocortisone/pramoxine. No dietary restrictions necessary.
No significant food interactions. Avoid caffeine and stimulants as they may increase cardiovascular side effects (tachycardia, palpitations). No dietary restrictions required.
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.
FDA Pregnancy Category C. No adequate well-controlled studies in pregnant women. In animal studies, albuterol sulfate caused fetal malformations (cleft palate, limb defects) at doses 0.4-1.2 times the maximum human daily inhalation dose. Risk cannot be ruled out; use only if potential benefit justifies potential risk. For trimester-specific risks: first trimester: potential for orofacial clefts and limb defects; second/third trimesters: risk of maternal tachycardia and hypoglycemia in neonate; labor inhibition near term; possible neonatal transient hypoglycemia.
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.
Albuterol is excreted into human breast milk in small amounts (M/P ratio not established). No reported adverse effects in nursing infants. Use with caution in lactating women; benefit of breastfeeding should outweigh potential risk to infant. Monitor infant for signs of beta-adrenergic stimulation (tachycardia, irritability).
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.
No specific dose adjustment required; however, pharmacokinetic changes in pregnancy (increased volume of distribution, increased clearance) may theoretically require dose frequency adjustment. Use the lowest effective dose and monitor clinical response. No dose adjustment needed based on current evidence.
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.
Primarily a rescue inhaler for acute asthma exacerbations. Not for maintenance therapy. Shake well before each use. Prime with 3 test sprays when new or not used for >2 weeks. Use spacer device to improve lung deposition and reduce oropharyngeal side effects. Monitor for paradoxical bronchospasm. Tachycardia and hypokalemia can occur with overuse. Replace canister after 200 actuations.
Apply a small amount to the affected area as directed, usually 2-4 times daily.,Do not cover the area with bandages or dressings unless instructed by your doctor.,Avoid use on broken skin, open wounds, or infected areas unless specifically prescribed.,Do not use for more than 2 weeks without medical supervision, especially in the anogenital region.,If symptoms do not improve or worsen, contact your healthcare provider.,Keep away from eyes, mouth, and other mucous membranes.,Wash hands after applying unless treating hands.,Inform your doctor if you are pregnant, planning to become pregnant, or breastfeeding.
Use only as needed for shortness of breath, wheezing, or chest tightness.,Do not use more frequently than prescribed; overuse can lead to serious side effects.,Shake the inhaler vigorously for 5 seconds before each spray.,Prime the inhaler by releasing 3 test sprays into the air before first use or if not used for more than 2 weeks.,Use a spacer device if prescribed to improve medication delivery to the lungs.,Rinse mouth with water after each use to prevent thrush (oral fungal infection).,Seek immediate medical help if symptoms worsen or if you need more than 2 puffs per week for relief.,Store at room temperature away from moisture and heat; do not freeze.
