What Is Prednisone?
Prednisone is a synthetic corticosteroid medication that mimics the effects of cortisol, a hormone naturally produced by the adrenal glands. As one of the most widely prescribed anti-inflammatory and immunosuppressive drugs globally, prednisone is used to treat a broad spectrum of conditions including autoimmune disorders, severe allergies, asthma exacerbations, inflammatory bowel disease, certain cancers, and organ transplant rejection. It is available in oral tablets, liquid solutions, and injectable formulations, with typical strengths ranging from 2.5 mg to 50 mg.
First approved by the FDA in 1955, prednisone remains a cornerstone of modern pharmacotherapy due to its potent glucocorticoid activity. It works by binding to glucocorticoid receptors inside cells, modulating gene expression to reduce the production of pro-inflammatory cytokines and immune cells. This makes it effective for conditions where the immune system overreacts or attacks healthy tissue.
Mechanism of Action
Prednisone is a prodrug that is converted by the liver into its active metabolite, prednisolone. Prednisolone then binds to the glucocorticoid receptor (GR) in the cytoplasm, forming a complex that translocates to the cell nucleus. There, it interacts with glucocorticoid response elements (GREs) on DNA to:
- Suppress transcription of pro-inflammatory genes (IL-1, IL-2, IL-6, TNF-alpha, IFN-gamma)
- Enhance transcription of anti-inflammatory proteins (lipocortin-1, IL-10)
- Inhibit phospholipase A2, reducing prostaglandin and leukotriene synthesis
- Decrease vascular permeability and leukocyte migration to inflamed tissues
- Suppress activation and proliferation of T-lymphocytes and other immune cells
These combined effects provide rapid and powerful anti-inflammatory and immunosuppressive action, typically within hours of oral administration.
Uses and Indications
Prednisone is FDA-approved and clinically used for a wide variety of conditions across multiple medical specialties:
| Category | Specific Conditions |
|---|---|
| Rheumatologic/Autoimmune | Rheumatoid arthritis, lupus erythematosus, polymyalgia rheumatica, vasculitis, sarcoidosis |
| Respiratory | Severe asthma, COPD exacerbations, aspiration pneumonia |
| Allergic/Immunologic | Severe allergic reactions, angioedema, drug hypersensitivity reactions |
| Dermatologic | Severe psoriasis, pemphigus, contact dermatitis, eczema flares |
| Gastrointestinal | Ulcerative colitis, Crohn’s disease, autoimmune hepatitis |
| Renal | Nephrotic syndrome, glomerulonephritis |
| Hematologic/Oncologic | Leukemia, lymphoma, multiple myeloma, autoimmune hemolytic anemia |
| Neurologic | Multiple sclerosis exacerbations, cerebral edema (from tumors) |
| Transplant | Immunosuppression post-organ transplant (combined with other agents) |
Dosage Information
Dosage of prednisone is highly individualized and depends on the condition being treated, severity, patient response, and duration of therapy. The general principle is to use the lowest effective dose for the shortest possible duration.
| Condition | Typical Starting Dose | Taper Schedule |
|---|---|---|
| Acute inflammation/allergy | 5–60 mg/day | Taper over 1–2 weeks |
| Rheumatologic conditions | 10–30 mg/day | Slow taper over 1–3 months |
| Severe autoimmune flares | 40–80 mg/day | Gradual reduction by 5–10 mg/week |
| Pulse therapy (acute organ rejection) | 250–1000 mg/day IV | Rapid taper over 3–7 days |
For children, dosing is typically weight-based at 0.1–2 mg/kg/day. High-dose or long-term therapy (over 3 weeks) requires a gradual tapering schedule to allow the adrenal glands to resume normal cortisol production and to avoid adrenal crisis. Never discontinue prednisone abruptly after prolonged use.
Side Effects and Safety
Prednisone is associated with a wide range of potential side effects, particularly with long-term use (more than 3 weeks) or at high doses. Side effects are generally dose-dependent and may be minimized by using the lowest effective dose and limiting duration of therapy.
| System | Common Side Effects | Management |
|---|---|---|
| Endocrine/Metabolic | Weight gain, hyperglycemia, diabetes mellitus, Cushing’s syndrome (moon face, buffalo hump), adrenal suppression | Monitor blood glucose; slow taper to avoid adrenal crisis |
| Musculoskeletal | Osteoporosis, muscle wasting, avascular necrosis of hip | Calcium + vitamin D supplementation; bisphosphonates if high risk |
| Cardiovascular | Hypertension, fluid retention, electrolyte imbalances | Monitor blood pressure and electrolytes; sodium restriction |
| Gastrointestinal | Gastric ulcers, pancreatitis, increased appetite | Consider proton pump inhibitor (PPI) prophylaxis |
| Neuropsychiatric | Insomnia, mood swings, anxiety, depression, psychosis (rare) | Dose reduction; psychiatric referral if needed |
| Immunologic | Increased infection risk (bacterial, fungal, viral), impaired wound healing | Monitor for infections; avoid live vaccines |
| Ocular | Glaucoma, posterior subcapsular cataracts | Regular eye exams |
| Dermatologic | Thin skin, easy bruising, acne, hirsutism | Supportive skin care |
Prednisone vs Other Corticosteroids
| Corticosteroid | Relative Anti-inflammatory Potency | Mineralocorticoid Activity | Duration of Action | Key Differences |
|---|---|---|---|---|
| Prednisone | 4 | 0.8 | Intermediate (12–36h) | Prodrug (requires hepatic conversion); good oral bioavailability |
| Prednisolone | 4 | 0.8 | Intermediate | Active metabolite; preferred in liver impairment |
| Methylprednisolone | 5 | 0.5 | Intermediate | Slightly stronger; less mineralocorticoid; IV formulation available |
| Dexamethasone | 25–30 | 0 | Long (36–72h) | Very potent; no salt retention; used for cerebral edema |
| Hydrocortisone | 1 | 1 | Short (8–12h) | Natural hormone; more mineralocorticoid; used for adrenal replacement |
| Betamethasone | 25–30 | 0 | Long | Similar to dexamethasone |

Frequently Asked Questions (FAQ)
Can prednisone be taken long-term?
Long-term use is possible but carries significant risks including osteoporosis, diabetes, adrenal suppression, and increased infection risk. Doctors prescribe the lowest effective dose for the shortest duration and monitor closely for adverse effects.
How do I taper off prednisone?
Tapering schedules vary depending on dose and duration of therapy. A typical schedule after 2–3 weeks of use reduces the dose by 2.5–5 mg every 3–7 days. Always follow your doctor’s specific tapering plan.
Can I take ibuprofen with prednisone?
Combining NSAIDs like ibuprofen with prednisone increases the risk of gastrointestinal bleeding and ulcers. If concomitant use is necessary, a proton pump inhibitor (PPI) such as omeprazole is often prescribed for gastric protection.
Does prednisone cause weight gain?
Yes, prednisone often causes increased appetite and fluid retention, leading to weight gain. This is dose-dependent and partially reversible upon discontinuation. Dietary modifications and sodium restriction can help manage this side effect.
Is prednisone safe during pregnancy?
Prednisone is classified as FDA Pregnancy Category C. While it may be used when benefits outweigh risks (e.g., severe autoimmune disease during pregnancy), it should be used at the lowest effective dose. Maternal steroid use has been associated with a small increased risk of oral clefts and preterm birth.
Safety Precautions
Before starting prednisone, inform your healthcare provider about all medical conditions, especially: diabetes, hypertension, osteoporosis, glaucoma, tuberculosis, fungal infections, peptic ulcer disease, and recent vaccinations. Live vaccines should be avoided during therapy. Regular monitoring of blood glucose, blood pressure, bone density (if long-term), and eye exams are recommended. Prednisone should be stored at room temperature (20–25°C) away from moisture.
Drug Interactions
Prednisone has clinically significant interactions with several drug classes. Anticoagulants (warfarin) may have altered effect; cyclosporine increases risk of seizure and toxicity; NSAIDs and aspirin increase GI bleeding risk; antidiabetic drugs may require dose adjustment due to hyperglycemic effect; CYP3A4 inducers (rifampin, phenytoin, carbamazepine) reduce prednisone efficacy; CYP3A4 inhibitors (ketoconazole, ritonavir) increase prednisone exposure.
