3-4 hours (terminal); prolonged in renal impairment (up to 8-10 hours) and in elderly patients.
Acetic acid: not applicable; hydrocortisone: plasma half-life ~1.5 hours (biologic half-life 8–12 hours). Due to low systemic absorption from topical application, systemic half-life is clinically irrelevant.
Metabolized in the liver via sulfonation (sulfotransferase enzymes) and to a minor extent by catechol-O-methyltransferase (COMT).
Acetic acid is metabolized via the Krebs cycle to carbon dioxide and water. Hydrocortisone is primarily metabolized in the liver.
Primarily renal (60-70% as unchanged drug and metabolites); fecal elimination accounts for a minor fraction (<5%).
Acetic acid: minimal systemic absorption; hydrocortisone: hepatic metabolism, renal excretion of metabolites (<5% unchanged). Less than 10% of applied dose excreted in urine as metabolites; biliary/fecal excretion negligible.
Approximately 25% bound to albumin.
Hydrocortisone: ~90% bound to corticosteroid-binding globulin (CBG) and albumin. Acetic acid: negligible binding.
~0.6 L/kg; indicates distribution into total body water.
Hydrocortisone: Vd ~0.3–0.5 L/kg (systemic); topical application results in negligible systemic distribution.
Inhalation: ~10-20% (dependent on device and technique); Oral: ~15-20% (due to extensive first-pass metabolism).
Topical: ~1–5% of hydrocortisone absorbed through intact skin; higher with inflamed skin or occlusion. Acetic acid: negligible systemic absorption.
No specific dose adjustment recommended for renal impairment; use with caution in severe renal impairment (e GFR <30 m L/min/1.73 m²) due to potential for increased systemic exposure.
No dose adjustment required for acetic acid. Hydrocortisone is minimally affected by renal impairment; no specific adjustment recommended.
No specific dose adjustment recommended; caution in severe hepatic impairment (Child-Pugh Class C) due to reduced clearance.
No dose adjustment required for acetic acid. For hydrocortisone, use with caution in severe hepatic impairment (Child-Pugh C) due to reduced metabolism; consider reducing frequency or dose, though no specific guidelines exist.
Subcutaneous: 5-10 mcg/kg every 1-2 hours as needed (max 0.5 mg); Intravenous: 5-10 mcg/kg over 1 minute (max 0.5 mg); Inhalation (MDI): 1-2 inhalations (0.2-0.4 mg) every 4-6 hours; Nebulized: 0.01-0.03 mg/kg (max 1 mg) every 6-8 hours.
Safety and efficacy not established in pediatric patients; use not recommended.
Initiate at lower end of dosing range (e.g., subcutaneous 0.125 mg); monitor for tachycardia, hypertension, and tremor; consider age-related decline in renal and hepatic function.
No specific dose adjustment required. Use caution due to potential skin atrophy and systemic absorption; limit duration to minimum effective course.

No significant food interactions. However, avoid excessive caffeine intake (coffee, tea, cola) as it may exacerbate beta-agonist side effects like palpitations and tremor.
No clinically relevant food interactions. No specific dietary restrictions.
Insufficient human data; animal studies show no evidence of teratogenicity at clinically relevant doses. Risk cannot be excluded; use only if clearly needed. First trimester: limited data suggest no major malformations. Second and third trimesters: may cause fetal tachycardia, hypoglycemia, and transient hypocalcemia. Avoid in preterm labor due to maternal and fetal adverse effects.
Topical corticosteroids are generally considered low risk in pregnancy. Hydrocortisone is a weak corticosteroid. No increased risk of congenital malformations has been observed with topical use. Systemic absorption is minimal with small-area application. Avoid prolonged use on large areas, occlusive dressings, or high-potency steroids. Acetic acid has no known teratogenic risk.
Excreted into breast milk in small amounts; M/P ratio approximately 2.5. No adverse effects reported in infants at therapeutic maternal doses. However, monitor infant for signs of beta-2 adrenergic stimulation (e.g., tachycardia, irritability). Consider risk-benefit.
Minimal systemic absorption of topical hydrocortisone and acetic acid; unlikely to affect the breastfed infant. Use on limited areas, avoid application to breast or nipple area. M/P ratio not established.
No specific dose adjustments recommended for asthma or COPD. However, in preterm labor (off-label), use lowest effective dose and shortest duration due to increased risk of maternal pulmonary edema, cardiac ischemia, and fetal effects. Monitor closely.
No dosing adjustments required for pregnancy. Use lowest effective dose for shortest duration to minimize systemic absorption.
BRICANYL (terbutaline sulfate) is a beta-2 adrenergic agonist used for bronchodilation in asthma and COPD. It can cause transient hypokalemia, hyperglycemia, and tremor. Use with caution in patients with diabetes, hypertension, or hyperthyroidism. Monitor serum potassium in patients on diuretics or with hypoxia. Not recommended for acute severe asthma as monotherapy; prefer short-acting beta-agonists like albuterol.
Combination otic suspension for external otitis. Ensure tympanic membrane is intact before use; perforation risks ototoxicity. Shake well before instillation. Use for no longer than 10 days to avoid fungal overgrowth or adrenal suppression. Warm bottle in hands to avoid caloric vertigo. Contraindicated in viral or fungal infections of the ear canal.

No interactions on record
"Hydrocortisone, a corticosteroid, may inhibit the hepatic metabolism of doxycycline, a tetracycline antibiotic, leading to increased doxycycline plasma concentrations. This elevation can potentiate doxycycline's adverse effects, such as gastrointestinal disturbance, photosensitivity, and hepatotoxicity. Clinically, this interaction may reduce the therapeutic window of doxycycline, requiring dose adjustment or alternative therapy selection."
"Fluconazole, a potent inhibitor of cytochrome P450 3A4 (CYP3A4), can significantly reduce the hepatic clearance of hydrocortisone, a corticosteroid metabolized primarily by CYP3A4. This interaction leads to increased systemic exposure to hydrocortisone, potentially resulting in exaggerated corticosteroid effects such as hyperglycemia, immunosuppression, and adrenal suppression. Clinically, patients may experience symptoms of Cushing's syndrome or require dose adjustments to avoid toxicity."
"Rifaximin, a non-systemic antibiotic primarily acting in the gastrointestinal tract, may inhibit intestinal P-glycoprotein (P-gp), reducing the efflux of corticosteroids like hydrocortisone. This can lead to increased systemic absorption and elevated serum concentrations of hydrocortisone, potentially enhancing both therapeutic and adverse effects such as hyperglycemia, immunosuppression, and adrenal suppression."
