Indications and Uses of Prednisone
Prednisone is indicated for a broad spectrum of conditions, leveraging its anti-inflammatory and immunosuppressive properties:
Rheumatoid Arthritis: Treats rheumatoid arthritis by reducing joint inflammation and pain, often as a bridge therapy, supported by rheumatology guidelines.
Systemic Lupus Erythematosus (SLE): Manages SLE flares, controlling skin, joint, and organ involvement, per autoimmune disease protocols.
Asthma: Controls acute asthma exacerbations, reducing airway inflammation, used short-term with bronchodilators, per pulmonary guidelines.
Allergic Reactions: Treats severe allergies (e.g., anaphylaxis, angioedema), stabilizing symptoms, under allergist supervision.
Ulcerative Colitis: Induces remission in moderate to severe ulcerative colitis, reducing mucosal inflammation, supported by gastroenterology studies.
Crohn’s Disease: Manages Crohn’s disease flares, controlling intestinal inflammation, often with biologics, per IBD protocols.
Multiple Sclerosis (MS): Treats acute MS exacerbations, improving neurological function, used short-term, per neurology guidelines.
Chronic Obstructive Pulmonary Disease (COPD): Controls COPD exacerbations, reducing respiratory distress, with evidence from pulmonary research.
Immune Thrombocytopenia (ITP): Used off-label to increase platelet counts in ITP, managing bleeding risk, supported by hematology data.
Sarcoidosis: Manages pulmonary and systemic sarcoidosis, reducing granuloma formation, with evidence from pulmonology studies.
Polymyalgia Rheumatica: Treats polymyalgia rheumatica, alleviating stiffness and pain, often with low doses, per rheumatology protocols.
Graft-Versus-Host Disease (GVHD): Employed off-label post-transplant to control GVHD, reducing immune attack on host tissues, with transplant medicine evidence.
Pemphigus Vulgaris: Controls severe pemphigus vulgaris, healing blisters and erosions, under dermatology supervision.
Temporal Arteritis: Manages temporal arteritis, preventing vision loss, with rapid initiation, per rheumatology guidelines.

Dosage for Pregnant Women
Pregnancy Category C: Use only if benefits outweigh risks (e.g., severe autoimmune disease). Consult an obstetrician, with fetal monitoring.
Dosage Adjustments
Renal Impairment: No adjustment needed; monitor in severe cases (CrCl <30 mL/min).
Hepatic Impairment: No adjustment; monitor liver function in severe cases.
Elderly: Start with lower doses (e.g., 5 mg daily); increase cautiously.
Concomitant Medications: Adjust if combined with CYP3A4 inducers/inhibitors (e.g., rifampin, ketoconazole), altering metabolism.
Additional Considerations
- Take this active ingredient in the morning with food to mimic cortisol rhythm and reduce stomach irritation.
- Use a tapering schedule for doses above 5 mg daily to prevent adrenal crisis.
How to Use Prednisone
Administration:
Swallow tablets or take oral solution with food or milk; shake solution well before use.
Take delayed-release tablets in the morning on an empty stomach if directed.
Timing: Use once daily in the morning or as prescribed (e.g., every other day), maintaining consistency.
Monitoring: Watch for weight gain, mood changes, or signs of infection (e.g., sore throat).
Additional Tips:
- Store at 20–25°C (68–77°F), protecting from moisture and heat.
- Keep out of reach of children due to toxicity risk.
- Report severe swelling, vision changes, or signs of allergic reaction immediately.
Contraindications for Prednisone
Hypersensitivity: Patients with a known allergy to Prednisone or corticosteroids.
Systemic Fungal Infections: Contraindicated due to immunosuppression risk.
Live Virus Vaccines: Avoid during therapy due to reduced efficacy.
Untreated Active Infections: Contraindicated unless infection is controlled.
Side Effects of Prednisone
Common Side Effects
- Weight Gain (20–40%, manageable with diet)
- Insomnia (15–30%, reduced with evening dosing)
- Increased Appetite (10–25%, controlled with nutrition)
- Mood Changes (10–20%, monitored with support)
- Facial Swelling (5–15%, decreases with tapering)
These effects may subside with dose adjustment or tapering.
