- Severe allergic reactions and anaphylaxis
- Asthma exacerbations and COPD flares
- Multiple sclerosis relapses
- Lupus (SLE), vasculitis, dermatomyositis
- Inflammatory bowel disease (Crohn’s, ulcerative colitis)

Comparative Table: Glucocorticoids (2025 Data)
| Drug | Anti-inflammatory Potency | Mineralocorticoid Activity | Duration of Action | Equivalent Dose |
|---|---|---|---|---|
| Methylprednisolone | 5 | 0.5 | Intermediate (12–36 h) | 4 mg |
| Prednisone | 4 | 0.8 | Intermediate | 5 mg |

| Hydrocortisone | 1 | 1 | Short (8–12 h) | 20 mg |
Mechanism of Action
Methylprednisolone binds to glucocorticoid receptors, altering gene transcription to inhibit pro-inflammatory cytokines (IL-1, IL-6, TNF-α), reduce immune cell migration, and suppress phospholipase A2, resulting in profound anti-inflammatory and immunosuppressive effects.
Side Effects & Monitoring (2025)
Short-term (<2 weeks): insomnia, mood changes, increased appetite, fluid retention.
Long-term: osteoporosis, adrenal suppression, hyperglycemia, cataracts, increased infection risk.
