Its exact mechanism involves binding to intracellular glucocorticoid receptors, leading to modulation of gene expression and subsequent reduction in inflammatory mediators. ## Primary Indications * Inflammatory conditions (e.g., severe asthma, allergic reactions, dermatitis) * Autoimmune diseases (e.g., rheumatoid arthritis, lupus erythematosus) * Certain hematologic and oncologic conditions * Adrenal insufficiency (as replacement therapy) ## Adult Dosing Dosing is highly variable and depends on the specific indication, severity of disease, and patient response. Doses can range from micrograms to hundreds of milligrams daily, administered orally, intravenously, topically, or via inhalation. Specific protocols are often followed for acute exacerbations or initial treatment. ## Pediatric Dosing Pediatric dosing is also highly individualized and often based on weight and severity of the condition. Doses may be lower than adult doses. For certain indications, specific pediatric guidelines exist. ## Dose Adjustments * **Renal Impairment:** No specific dose adjustment is typically required unless the formulation contains excipients that are renally cleared. * **Hepatic Impairment:** May require dose reduction due to decreased metabolism. * **Stress Doses:** Increased doses may be needed during periods of significant physiological stress (e.g., surgery, infection, trauma). ## Contraindications * Known hypersensitivity to the drug. * Active systemic fungal infections. * Live virus vaccinations (in immunosuppressed patients). * Caution in patients with: active peptic ulcer disease, osteoporosis, recent myocardial infarction, hypertension, diabetes mellitus, glaucoma, cataracts, infections. ## Adverse Effects Common: Hyperglycemia, insomnia, mood changes, increased appetite, weight gain, fluid retention, peptic ulceration, increased susceptibility to infection, adrenal suppression, growth suppression (in children), skin thinning, acne. Serious: Cushingoid effects, psychosis, osteoporotic fractures, avascular necrosis, opportunistic infections, anaphylaxis. ## Key Drug Interactions * **CYP3A4 Inhibitors (e.g., ketoconazole, ritonavir):** May increase Mega%25252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252520cv concentrations and side effects. * **CYP3A4 Inducers (e.g., rifampin, phenytoin):** May decrease Mega%25252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252520cv concentrations. * **Diuretics (potassium-depleting):** Increased risk of hypokalemia. * **Anticoagulants (e.g., warfarin):** May alter anticoagulant effect. * **Antidiabetics:** May increase blood glucose levels, requiring adjustment of antidiabetic therapy. * **Live Vaccines:** Reduced immune response and increased risk of complications. ## Monitoring * Blood glucose levels. * Electrolytes (especially potassium). * Signs of infection. * Growth and development in pediatric patients. * Bone density with prolonged use. * Ophthalmic exams (intraocular pressure, cataracts) with prolonged use. * Signs of adrenal suppression (e.g., during tapering or withdrawal). ## Clinical Pearls * Use the lowest effective dose for the shortest possible duration. * Taper gradually when discontinuing to avoid adrenal insufficiency. * Educate patients on signs of infection and hyperglycemia. * Consider "stress doses" during periods of illness or injury. * Advise patients to carry a medical alert card indicating corticosteroid use. *** *Disclaimer: This information is for educational purposes only and does not substitute professional medical advice.
