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.
Relaxes bronchial smooth muscle by stimulating beta2-adrenergic receptors, increasing cyclic AMP, and inhibiting mediator release from mast cells.
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,Acute prophylaxis against 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.
Inhaled: Nebulized solution 0.63 mg or 1.25 mg three times daily every 6-8 hours; or 0.63 mg twice daily in patients with asthma. Alternatively, 2.5 mg three times daily via nebulization.
1.5-2 hours (terminal) after intravenous administration; prolonged in hepatic impairment.
2-5 hours (procainamide); 6-8 hours (N-acetylprocainamide); prolonged in renal impairment (up to 20 hours)
Hydrocortisone is primarily hepatic via CYP3A4; iodoquinol is not extensively metabolized, with partial glucuronidation and enterohepatic circulation.
Metabolized primarily by catechol-O-methyltransferase (COMT) and to a lesser extent by sulfatase enzymes in the gastrointestinal tract.
Renal (primarily as metabolites; <5% unchanged); fecal (biliary excretion of metabolites).
Renal: ~70% as unchanged drug and active metabolite (N-acetylprocainamide) within 24 hours; biliary/fecal: minimal (<5%)
90-95% (albumin and corticosteroid-binding globulin).
15-20% bound to albumin and alpha-1-acid glycoprotein
0.4-0.6 L/kg; indicates distribution into total body water and tissues.
1.5-2.5 L/kg; distributes widely into tissues with high affinity for cardiac tissue
Oral: 80-90%; Intramuscular: 100%; Intravenous: 100%.
Oral immediate-release: 75-95%; IM: 100%; IV: 100%
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 specific dose adjustment required; drug undergoes minimal renal excretion. Use with caution in severe renal impairment (Cr Cl <30 m L/min) due to potential for systemic accumulation.
No specific adjustment for topical use. In Child-Pugh C cirrhosis, consider the risk of systemic corticosteroid accumulation; use with caution.
No specific dose adjustment for Child-Pugh Class A or B. For Child-Pugh Class C, consider dose reduction by 50% due to reduced clearance.
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 2-12 years: Nebulized solution 0.31 mg, 0.63 mg, or 1.25 mg three times daily every 6-8 hours based on severity. For children ≥12 years, same as adult dosing.
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.
Start at lower end of dosing range (0.63 mg three times daily) due to potential age-related renal impairment and increased sensitivity to beta-agonists. Monitor for tachycardia and tremors.

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,Cardiovascular effects including increased heart rate and blood pressure,Hypokalemia,Immediate hypersensitivity reactions
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 levalbuterol or any component of the product
No clinically significant food interactions are reported for topical hydrocortisone/pramoxine. No dietary restrictions necessary.
No specific food interactions. Avoid caffeine and other stimulants as they may increase side effects like nervousness and rapid heartbeat.
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.
ACCUNEB (levalbuterol) is a beta-2 adrenergic agonist. Based on animal studies and human data, there is no evidence of teratogenicity. However, during the second and third trimesters, beta-agonists may cause fetal tachycardia, hypoglycemia, and hypocalcemia. Use only if potential benefit justifies risk.
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.
Levalbuterol is excreted into breast milk in small amounts. The M/P ratio is unknown. Caution is advised; monitor infant for signs of beta-adrenergic stimulation (e.g., 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.
Pharmacokinetic changes in pregnancy (e.g., increased volume of distribution, clearance) may require dose adjustments. Titrate to clinical effect; monitor for bronchospasm and side effects. No specific dose adjustment guidelines are established; use lowest effective dose.
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.
ACCUNEB (levalbuterol) is the R-isomer of albuterol, designed to reduce beta-adrenergic side effects. It is preferred in patients with tachycardia or sensitivity to beta-agonists. Monitor for paradoxical bronchospasm; discontinue immediately if occurs. Nebulized solution should be used with a jet nebulizer connected to an air compressor. Not for acute deterioration unless patient is already on regular therapy.
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 prescribed; do not increase dose or frequency without consulting your doctor.,Shake the nebulizer solution well before use. Do not mix with other medications unless instructed.,If you experience worsening breathing, chest tightness, or hives, stop the medication and seek medical help immediately.,Rinse mouth with water after each use to prevent throat irritation and thrush.,Store at room temperature away from light and moisture.
