## Overview
This drug is a synthetic corticosteroid with potent anti-inflammatory and immunosuppressive properties.
## Primary Indications
* Management of inflammatory conditions (e.g., allergic reactions, dermatological disorders, rheumatoid arthritis, inflammatory bowel disease).
* Treatment of immunosuppression (e.g., organ transplant recipients).
* Management of certain endocrine disorders.
## Adult Dosing
Dosing is highly individualized and depends on the condition being treated, severity, and patient response. Typical starting doses range from **1 mg to 9 mg daily**, administered orally in a single dose or divided doses. For acute exacerbations or severe disease, higher doses may be necessary, with typical ranges of **10 mg to 40 mg daily**. Specific protocols may dictate higher initial doses.
## Pediatric Dosing
Pediatric dosing is not well established and should be determined by a specialist. Dosing is typically based on the child's weight and the severity of the condition.
## Dose Adjustments
* **Renal Impairment:** No specific dose adjustment is typically required, but monitor for increased corticosteroid effects.
* **Hepatic Impairment:** Dose adjustments may be necessary due to altered metabolism. Monitor closely.
* **Adrenal Suppression:** Patients on chronic therapy may require stress-dose corticosteroids during illness, surgery, or trauma.
## Contraindications
* Systemic fungal infections.
* Known hypersensitivity to the drug.
* Use with caution in patients with active infections (bacterial, viral, parasitic).
## Adverse Effects
Common adverse effects include hyperglycemia, insomnia, mood changes, increased appetite, weight gain, and fluid retention. Long-term or high-dose use can lead to Cushingoid features, osteoporosis, adrenal suppression, impaired wound healing, peptic ulceration, cataracts, glaucoma, and increased susceptibility to infections.
## Key Drug Interactions
* **CYP3A4 Inducers (e.g., rifampin, phenytoin, phenobarbital):** May increase corticosteroid metabolism and reduce efficacy.
* **CYP3A4 Inhibitors (e.g., ketoconazole, protease inhibitors):** May decrease corticosteroid metabolism and increase risk of toxicity.
* **Diuretics (Thiazide, Loop):** Increased risk of hypokalemia.
* **Vaccines:** Live vaccines should be avoided in patients receiving immunosuppressive doses.
* **Antidiabetics:** May require increased doses to maintain glycemic control.
## Monitoring
* **Glucose levels:** Especially in patients with diabetes or at risk.
* **Electrolytes:** Particularly potassium.
* **Blood pressure:** Corticosteroids can cause hypertension.
* **Bone mineral density:** With long-term use.
* **Ophthalmologic examinations:** For signs of glaucoma or cataracts.
* **Signs of infection:** Corticosteroids can mask infection.
* **Growth and development:** In pediatric patients.
## Clinical Pearls
* Administer oral doses with food to minimize gastrointestinal upset.
* For patients requiring long-term therapy, consider alternate-day dosing to minimize adrenal suppression and side effects, though efficacy may be reduced.
* Taper the dose gradually when discontinuing therapy to prevent adrenal insufficiency.
* Educate patients on the signs and symptoms of infection and the importance of reporting them promptly.
