1. What is Prednisolone?
Prednisolone is a synthetic corticosteroid (glucocorticoid) that mimics the hormone cortisol produced by the adrenal glands. It has powerful anti‑inflammatory, antiproliferative, and immunosuppressive properties.

3. Typical Indications
| Condition | Typical Dose (Adults) | Notes |
|-----------|-----------------------|-------|
| Autoimmune diseases (e.g., rheumatoid arthritis, lupus) | 5–60 mg/day | Start low, titrate. |
| Allergic reactions (severe, anaphylaxis) | 10–30 mg IV/IM | Rapid onset. |
| Asthma exacerbations | 5–40 mg/day | Oral or IV; taper as symptoms improve. |
| Dermatologic conditions (eczema, psoriasis) | 0.1–1 mg/kg/day | Oral or topical. |
| Inflammatory bowel disease (Crohn’s, ulcerative colitis) | 0.5–1 mg/kg/day | Usually tapered. |
| Glucocorticoid‑resistant hypertension | 5–30 mg/day | Use cautiously. |
| Certain cancers (e.g., lymphoma) | 5–60 mg/day | Often part of combination chemotherapy. |
Never use high doses for prolonged periods without a clear indication—long‑term use can lead to serious side effects.

4. How It Works
1. Anti‑inflammatory – blocks prostaglandin and leukotriene synthesis, reduces edema and swelling.
2. Immunosuppressive – decreases T‑cell activation & cytokine release.
3. Metabolic effects – increases gluconeogenesis, promotes fat redistribution.
Because of these actions, prednisolone can alter many organ systems.

5. Common Side Effects
| System | Symptoms | Management |
|--------|----------|------------|
| Endocrine | Hyperglycemia, Cushingoid features | Monitor glucose; consider insulin or metformin. |
| Gastrointestinal | Peptic ulcer, gastritis | Give with food; consider proton pump inhibitor. |
| Musculoskeletal | Osteoporosis, muscle weakness | Calcium/vitamin D; bisphosphonates for high‑risk patients. |
| Immune | Infections, delayed wound healing | Avoid live vaccines; use prophylactic antibiotics if indicated. |
| Psychiatric | Mood swings, insomnia, psychosis | Dose adjustment; sleep hygiene; consult psychiatrist. |
| Dermatologic | Acne, skin thinning | Topical steroids; sun protection. |
| Hepatic | Elevated liver enzymes | Monitor LFTs. |
| Cardiovascular | Hypertension, fluid retention | Diuretics; monitor BP. |

7. Drug Interactions
| Drug | Interaction | Practical Tip |
|------|-------------|---------------|
| NSAIDs | ↑ GI bleeding risk | Use proton‑pump inhibitor. |
| Anticoagulants | ↑ bleeding risk | Monitor INR. |
| Antidiabetic agents | ↑ glucose | Adjust dose, monitor glucose. |
| Immunosuppressants | ↑ infection risk | Monitor for infections. |
| Stimulants (e.g., amphetamines) | ↑ blood pressure | Monitor BP. |
| Isoniazid | ↑ hepatotoxicity | Monitor liver enzymes. |

8. How to Take Prednisolone
1. Take with Food – reduces stomach irritation.
2. Same Time Daily – maintain steady blood levels.
3. Avoid Sudden Stop – taper gradually unless advised otherwise.
4. Hydrate – helps reduce fluid retention.
5. Keep a Diary – note mood changes, headaches, or new symptoms.

9. Tapering (Stopping the Medication)
| Situation | Typical Taper Schedule | Reason |
|-----------|-----------------------|--------|
| Short courses (<4 weeks) | 2–3 days after finishing | Avoid withdrawal. |
| Long courses (≥4 weeks) | Reduce dose by 10–25 % every 1–2 weeks | Prevent adrenal insufficiency. |
| Very high doses | Reduce by 10 % every 3–4 days | Adrenal suppression may need more gradual taper. |
Always follow your doctor’s exact taper plan; abrupt discontinuation can lead to adrenal crisis.

10. What to Do in an Emergency
- Severe allergic reaction – treat with antihistamine, epinephrine, and call emergency services.
- Signs of adrenal crisis (severe weakness, dizziness, low blood pressure) – urgent medical attention; may need IV hydrocortisone.
- Sudden severe headache or vision changes – could signal cerebral edema or hemorrhage; seek immediate care.

11. Frequently Asked Questions
| Question | Answer |
|----------|--------|
| Can I take prednisolone with other steroids? | Generally not recommended. If you’re already on another systemic steroid, adding prednisolone increases the risk of side effects. |
| Is it safe to travel while on prednisolone? | Yes—just remember to keep it in its original container, avoid extreme temperatures, and carry a copy of your prescription. |
| Can I drive or operate heavy machinery? | If you experience dizziness or cognitive changes, avoid driving or operating heavy machinery until you know how you react. |
| Will prednisolone affect my pregnancy? | It can cross the placenta. Use only if absolutely necessary and with medical supervision. |
| Can I drink alcohol while taking prednisolone? | Limit alcohol; it can worsen GI upset and liver toxicity. |
