Indications and Uses of Prednisolone

Prednisolone is indicated for a broad spectrum of inflammatory, autoimmune, and allergic conditions, leveraging its potent anti-inflammatory and immunosuppressive properties:

Rheumatoid Arthritis: Treats rheumatoid arthritis, reducing joint pain and swelling, often as a bridge therapy with DMARDs, per rheumatology guidelines, with long-term efficacy data.

Systemic Lupus Erythematosus (SLE): Manages SLE flares, controlling symptoms like rash and nephritis, used with immunosuppressants, supported by autoimmune disease studies.

Asthma: Controls acute asthma exacerbations, reducing airway inflammation, administered orally or via IV, per pulmonary guidelines.

Allergic Rhinitis: Treats severe allergic rhinitis unresponsive to antihistamines, alleviating nasal congestion and sneezing, with allergy research backing.

Ulcerative Colitis: Manages moderate to severe ulcerative colitis flares, reducing mucosal inflammation, often with 5-ASA agents, supported by gastroenterology trials.

Multiple Sclerosis (MS): Used for acute MS relapses, speeding recovery, administered as high-dose IV followed by oral taper, per neurology protocols.

Chronic Obstructive Pulmonary Disease (COPD): Treats acute COPD exacerbations, improving lung function, with pulmonology evidence.

Autoimmune Hepatitis: Controls autoimmune hepatitis, preventing liver damage, used with azathioprine, supported by hepatology studies.

Pemphigus Vulgaris: Manages pemphigus vulgaris, reducing blister formation, often with rituximab, per dermatology research.

Nephrotic Syndrome: Treats nephrotic syndrome in children and adults, reducing proteinuria, with nephrology data.

Sarcoidosis: Controls systemic sarcoidosis, particularly pulmonary and ocular involvement, with emerging data from rheumatology.

Temporal Arteritis: Manages temporal arteritis to prevent vision loss, used with long-term low-dose therapy, per ophthalmology guidelines.

Anaphylaxis (Adjunct): Used off-label as an adjunct in refractory anaphylaxis, stabilizing symptoms, with emergency medicine support.

Idiopathic Thrombocytopenic Purpura (ITP): Treats ITP to increase platelet counts, often with IVIG, supported by hematology studies.

Eczema: Controls severe eczema flares unresponsive to topical treatments, improving skin integrity, with dermatologic evidence.

Dosage of Prednisolone

Dosage for Adults

Rheumatoid Arthritis: Initial: 5–10 mg daily, tapered to 2.5–5 mg for maintenance, adjusted for disease activity.

Asthma (Acute): 40–60 mg daily for 5–10 days, then taper, or 1–2 mg/kg IV for severe cases.

Ulcerative Colitis: 40–60 mg daily for 1–2 weeks, tapered over 2–3 months, with monitoring.

Multiple Sclerosis (Relapse): 1,000 mg IV daily for 3–5 days, followed by oral taper (e.g., 60 mg daily, reduced by 10 mg weekly).

Dosage for Children

Nephrotic Syndrome: 2 mg/kg daily (max 60 mg) for 4–6 weeks, then alternate-day therapy (1 mg/kg), under pediatric nephrologist supervision.

Asthma or Allergic Reactions: 1–2 mg/kg daily for 3–10 days, tapered, not recommended under 1 year unless critical.

Juvenile Idiopathic Arthritis: 0.5–1 mg/kg daily, tapered based on response, under pediatric rheumatology care.

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: Reduce dose by 25–50% in severe cases (Child-Pugh C); monitor.

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 with food or milk to reduce gastrointestinal irritation.
• Use a tapering schedule for doses >5 mg/day to prevent adrenal crisis.

How to Use Prednisolone

Administration:

Swallow tablets or take oral solution with food or milk; shake solution well.

Inject IV forms slowly over 10–30 minutes in a clinical setting.

Timing: Use once or twice daily, as directed, with consistent timing.

Monitoring: Watch for weight gain, mood changes, or signs of infection (e.g., fever).

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 Prednisolone

Hypersensitivity: Patients with a known allergy to Prednisolone or corticosteroids.

Systemic Fungal Infections: Contraindicated due to immunosuppression risk.

Live Virus Vaccines: Avoid during therapy due to reduced efficacy.

Untreated Infections: Contraindicated until infection is controlled.

Side Effects of Prednisolone

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 (5–20%, monitored with support)
• Facial Swelling (5–15%, decreases with tapering)

These effects may subside with dose adjustment.

Serious Side Effects

Additional Notes

• Regular monitoring for bone density, glucose, and eye health is advised.
• Report any unusual symptoms (e.g., severe joint pain, vision loss) immediately to a healthcare provider.
