Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Hydrocortisone is a corticosteroid hormone that binds to glucocorticoid receptors, modulating gene expression to suppress inflammation, inhibit immune response, and regulate metabolism.
Aclovate (alclometasone dipropionate) is a synthetic corticosteroid with anti-inflammatory, antipruritic, and vasoconstrictive properties. Its mechanism involves binding to glucocorticoid receptors, modulating gene expression to inhibit phospholipase A2, reducing arachidonic acid release, and decreasing prostaglandin and leukotriene synthesis.
Adrenocortical insufficiency (primary and secondary),Congenital adrenal hyperplasia,Inflammatory conditions (e.g., rheumatoid arthritis, ulcerative colitis),Allergic reactions (severe),Asthma exacerbations,Dermatologic disorders (topical use),Ophthalmic inflammation (ophthalmic use)
Relief of inflammatory and pruritic manifestations of corticosteroid-responsive dermatoses (e.g., atopic dermatitis, contact dermatitis, eczema, psoriasis) - FDA approved,Off-label: Treatment of mild to moderate plaque psoriasis, seborrheic dermatitis, and lichen planus
Adrenal insufficiency: oral 20-30 mg/day in divided doses; inflammatory conditions: 5-60 mg/day oral; IV/IM: hydrocortisone sodium succinate 50-100 mg every 4-6 hours.
Apply a thin film to affected skin areas twice daily. Not for ophthalmic, oral, or intravaginal use.
Terminal half-life: 1.5-2 hours (cortisol); clinical effect persists 8-12 hours due to glucocorticoid receptor binding
Terminal elimination half-life: approximately 6-8 hours after topical application; systemic absorption is minimal under normal use.
Primarily hepatic via CYP3A4 and other CYP450 enzymes, with reduction in the A-ring to inactive metabolites (e.g., tetrahydrocortisol).
Aclovate is metabolized in the skin and liver via ester hydrolysis to inactive metabolites. Systemic metabolism primarily involves cytochrome P450 enzymes (CYP3A4) for any absorbed fraction, but extensive first-pass metabolism limits systemic exposure.
Renal (primarily as metabolites, <1% unchanged); biliary/fecal (<5%)
Renal (primarily as metabolites, <5% unchanged), biliary/fecal (minor).
90-95% bound to corticosteroid-binding globulin (CBG) and albumin
Approximately 90%, primarily to albumin and corticosteroid-binding globulin (CBG).
0.5-0.8 L/kg; represents distribution into total body water, higher in obesity
Not well-characterized in topical use; after systemic absorption, Vd is approximately 1-2 L/kg, indicating distribution into tissues.
Oral: 96% (well absorbed); IM/IV: 100%; topical: minimal systemic absorption (<1% with intact skin)
Topical: approximately 1-3% systemic absorption on intact skin; increased up to 15% on occluded or damaged skin.
No specific adjustment required; monitor fluid/electrolytes in severe renal impairment.
No dose adjustment required. Topical use with minimal systemic absorption.
Dose reduction may be necessary in severe hepatic impairment; caution as metabolism is hepatic.
No dose adjustment required. Topical use with minimal systemic absorption.
Doses are weight-based; for adrenal insufficiency: 0.5-0.75 mg/kg/day in divided doses; for anti-inflammatory: 0.5-10 mg/kg/day.
Use smallest amount effective for shortest duration. Avoid prolonged use, occlusive dressings, or application to large surface areas. Safety in children <1 year not established.
Use lowest effective dose; monitor for osteoporosis, hypertension, and glucose intolerance.
Use with caution due to increased risk of skin atrophy and systemic absorption. Limit frequency and duration; avoid occlusive dressings.
None.
No FDA black box warning.
Immunosuppression and increased infection risk,Adrenal suppression with prolonged use,Cushing's syndrome with chronic use,Osteoporosis with long-term use,GI perforation risk in inflammatory bowel disease,Growth suppression in children,Fetal harm (category C),Ocular effects (cataracts, glaucoma),Fluid and electrolyte disturbances
Topical corticosteroids can cause hypothalamic-pituitary-adrenal (HPA) axis suppression, especially with prolonged use, large surface area, occlusion, or in pediatric patients.,Reversible HPA axis suppression may occur after discontinuation.,Systemic effects including Cushing's syndrome, hyperglycemia, and glucosuria have been reported.,Local adverse reactions: burning, itching, irritation, dryness, folliculitis, hypopigmentation, allergic contact dermatitis, maceration, secondary infection, skin atrophy, striae, and miliaria.,Use caution in patients with impaired skin integrity or areas of skin atrophy.,Pediatric patients may be more susceptible to systemic toxicity due to higher skin surface-to-body-weight ratio.
Systemic fungal infections,Hypersensitivity to hydrocortisone or any component,Administration of live or live-attenuated vaccines (relative),Herpes simplex keratitis (topical ophthalmic use),Peptic ulcer disease (relative),Uncontrolled hypertension (relative)
Hypersensitivity to alclometasone dipropionate or any component of the formulation.,Untreated bacterial, fungal, or viral skin infections (e.g., herpes simplex, varicella, tuberculosis of the skin).
No specific food interactions. However, high-sodium foods may exacerbate fluid retention; a low-sodium diet is recommended if edema occurs. Grapefruit juice does not significantly affect hydrocortisone. Avoid alcohol due to additive gastric irritation.
No known food interactions with topical Aclovate.
Hydrocortisone is a corticosteroid. Use during first trimester is associated with increased risk of oral clefts (odds ratio 1.5-3.0). Second and third trimester use may cause fetal adrenal suppression, growth restriction, and premature birth. Risk of premature rupture of membranes and intrauterine growth restriction increases with prolonged use.
Topical corticosteroids like ACLOVATE (alclometasone dipropionate) are generally considered low risk in pregnancy, but systemic absorption can occur. Class C: Fetal risk cannot be ruled out. Avoid extensive use or prolonged treatment, especially in first trimester. Second and third trimester: Use only if clearly needed, minimal area and duration.
Hydrocortisone is excreted into breast milk in low concentrations. M/P ratio approximately 0.4-1.0. Doses up to 20 mg/day are considered compatible with breastfeeding. Higher doses may suppress infant adrenal function; monitor infant for growth and adrenal suppression.
Safety unknown; likely minimal systemic absorption due to low potency. M/P ratio not established. Avoid application to breasts or large areas; use caution.
Due to increased clearance and protein binding changes, doses may need to be increased by 50-100% in the second and third trimesters. Monitor clinical response and adjust dose accordingly. Stress doses (e.g., 50-100 mg IV) should be given during labor and delivery.
No standard dose adjustment required; however, limit potency, frequency, and duration to lowest effective due to altered skin permeability. No pharmacokinetic changes necessitate dose change.
For acute adrenal insufficiency, give IV bolus of 100 mg hydrocortisone followed by 100 mg every 8 hours. Taper to oral replacement over days. In septic shock, stress-dose hydrocortisone (200 mg/day) may be used if vasopressor-dependent. Monitor for hyperglycemia, hypokalemia, and immunosuppression. Abrupt discontinuation can cause adrenal crisis.
Topical corticosteroids like Aclovate are classified as low-potency (Group VI). They are suitable for thin skin areas (e.g., face, flexures) and for children. Avoid prolonged use without interruption to minimize systemic absorption, especially in pediatric patients due to higher skin surface area-to-body weight ratio.
Take exactly as prescribed; do not stop suddenly without doctor's guidance.,Carry a medical alert card or bracelet indicating you take hydrocortisone.,Report signs of adrenal crisis: severe weakness, dizziness, nausea, vomiting, abdominal pain.,During illness or stress (e.g., surgery, infection), dose may need temporary increase; contact your doctor.,Avoid live vaccines during therapy.,Monitor for weight gain, swelling, mood changes, or high blood sugar symptoms (increased thirst, urination).
Apply a thin layer to affected skin only, not to normal surrounding skin.,Do not cover with bandages or dressings unless directed by your doctor.,Use for the prescribed duration; do not use longer than 2 weeks at a time.,Avoid contact with eyes, mouth, and open wounds.,Report any signs of skin thinning, redness, or irritation to your healthcare provider.
