Prednisone is a synthetic steroid that mimics the natural hormone cortisol. It’s a powerful anti‑inflammatory and immunosuppressive drug used to treat a wide variety of conditions, such as:
| Condition | How Prednisone Helps |
|-----------|----------------------|
| Autoimmune disorders (e.g., lupus, rheumatoid arthritis) | Suppresses the over‑active immune response. |
| Allergic reactions (e.g., severe asthma, anaphylaxis) | Reduces swelling, mucus production, and immune‑mediated inflammation. |
| Skin disorders (e.g., eczema, psoriasis) | Decreases redness, itching, and swelling. |
| Respiratory diseases (e.g., COPD exacerbations, asthma) | Improves breathing by reducing airway inflammation. |
| Certain cancers (e.g., leukemia, lymphoma) | Can help reduce tumor‑related inflammation and support chemotherapy. |
| Other (e.g., inflammatory bowel disease, some eye conditions) | Modulates immune activity and inflammation. |

Typical Dosage
- Adults: 5–60 mg daily, depending on the disease.
- Pediatrics: Often weight‑based (e.g., 0.5–1 mg/kg).
- Short courses: Often used for a few days to a week.
- Long‑term therapy: Usually tapered down gradually to minimize withdrawal and side‑effects.
Never alter your dose or stop taking prednisone without a doctor’s guidance—stopping abruptly can cause adrenal insufficiency.

Common Side‑Effects
| Category | Examples |
|----------|----------|
| Metabolic | Weight gain, fluid retention, increased appetite, high blood sugar. |
| Psychiatric | Mood swings, insomnia, anxiety, euphoria or depression. |
| Musculoskeletal | Muscle weakness, bone loss (osteoporosis) with long‑term use. |
| Gastro‑intestinal | Stomach irritation, ulcers, bleeding (especially if combined with NSAIDs). |
| Immune | Higher risk of infections, slow wound healing. |
| Ocular | Cataracts, glaucoma with chronic use. |
| Others | Acne, easy bruising, hypertension. |

Precautions & Contraindications
- Active infections (especially tuberculosis or fungal infections) – prednisone can worsen them.
- Glaucoma or cataract risk – monitor eye health.
- Bone disorders – consider calcium/vitamin D supplementation.
- Pregnancy – generally avoided in the first trimester; use only if benefits outweigh risks.
- Concurrent steroids – avoid combining with other systemic steroids unless prescribed.

Drug Interactions
| Drug | Interaction |
|------|-------------|
| NSAIDs, aspirin | ↑ risk of GI ulceration and bleeding. |
| Anticoagulants | May increase bleeding risk. |
| Metformin, insulin | Can worsen glucose control. |
| Immunosuppressants | Enhanced immunosuppression, increased infection risk. |
| CYP3A4 inhibitors/inducers (e.g., ketoconazole, rifampin) | Alter prednisone metabolism. |

Practical Tips
1. Take with food or a full glass of water to reduce stomach upset.
2. Take it in the morning (first thing in the day) to mimic the body’s natural cortisol rhythm.
3. Avoid abrupt discontinuation—taper slowly under your clinician’s guidance.
4. Watch for signs of infection—fever, new sore throat, urinary problems.
5. Keep a medication diary—note dose, timing, and any side‑effects.
6. Regular check‑ups—blood pressure, blood sugar, bone density, eye exams as recommended.

Bottom Line
Prednisone is a versatile steroid that can dramatically improve inflammation‑related conditions. Because it suppresses the immune system, it carries a risk of significant side‑effects, especially with prolonged use. Always follow your prescriber’s instructions, report any new symptoms, and schedule routine monitoring. If you have any specific concerns—like dosage, side‑effect management, or interactions with other meds—feel free to ask!
