Steroid Withdrawal & Glucocorticoid Tapering (Expanded)
Long-term glucocorticoid therapy suppresses the hypothalamic–pituitary–adrenal (HPA) axis. Abrupt discontinuation may cause adrenal insufficiency or adrenal crisis. Tapering must be individualized.
| Patients at Risk | Examples |
| High risk | Prednisolone ≥20 mg/day for >3–4 weeks |
| Moderate risk | Prednisolone 5–20 mg/day for several weeks to months |
| Additional risk factors | Repeated courses, evening dosing, dexamethasone, Cushingoid features |
Approximate Glucocorticoid Equivalence
| Drug | Approximate Equivalent Dose |
| Hydrocortisone | 20 mg |
| Prednisolone | 5 mg |
| Methylprednisolone | 4 mg |
| Dexamethasone | 0.75 mg |
Illustrative Tapering Strategy
| Current Prednisolone Dose | Example Taper |
| >20 mg/day | Reduce by 5–10 mg every 1–2 weeks if disease is controlled |
| 20–10 mg/day | Reduce by 2.5–5 mg every 2–4 weeks |
| 10–5 mg/day | Reduce by 1–2.5 mg every 2–4 weeks |
| <5 mg/day | Reduce by 0.5–1 mg every 2–4 weeks or consider physiologic hydrocortisone if indicated |
Important: This table is an example only. Tapering must be individualized according to the underlying disease, duration of therapy, relapse risk, and HPA-axis recovery.
Monitoring During Taper
| Assessment | Purpose |
| Symptoms | Fatigue, weakness, nausea, dizziness, hypotension |
| Underlying disease | Detect relapse |
| Morning serum cortisol | Assess HPA-axis recovery in selected patients |
| Dynamic testing | ACTH stimulation test when clinically indicated |
Sick-Day Rules
• Never stop replacement steroids abruptly.
• Increase glucocorticoid doses during significant illness according to your clinician’s instructions.
• Seek urgent medical care if vomiting prevents oral medication.
• Carry a steroid emergency card or medical alert identification.
