Corticosteroid (ICU/Septic Shock) Pregnancy: Use with caution — short-term use acceptable in septic shock; crosses placenta minimally

Hydrocortisone (ICU — Stress Dosing)

Brand names: Solu-Cortef

Adult dose

Dose: Septic shock: 200 mg/day IV (50 mg every 6h or 200 mg/24h infusion); Addisonian crisis: 100 mg IV bolus then 200 mg/24h
Route: IV
Frequency: Every 6 hours or continuous infusion
Max: 200 mg/day (septic shock protocol)
Used in refractory septic shock not responding to vasopressors. Continues for 5–7 days then taper. Add fludrocortisone 50 mcg once daily orally if available (APROCCHSS trial). Continuous infusion preferred to bolus dosing (avoids glucose spikes).

Paediatric dose

Dose: 1–2 mg/day/kg
Route: IV
Frequency: Divided every 6 hours
Max: 200 mg/day
Paediatric septic shock: 1–2 mg/kg/day in divided doses under specialist guidance.

Clinical pearls

  • APROCCHSS trial (2018): hydrocortisone + fludrocortisone in septic shock — significant mortality reduction (43% vs 49%); ADRENAL trial (2018): hydrocortisone alone — no mortality benefit but faster vasopressor weaning. Current practice: use in vasopressor-dependent refractory shock.
  • Surviving Sepsis 2021: suggest IV hydrocortisone 200 mg/day if haemodynamic stability not achieved with fluids and vasopressors
  • Strict glucose control required — target 6–10 mmol/L in ICU; hyperglycaemia worsens outcomes

Contraindications

  • Systemic infection without adequate antimicrobial cover

Side effects

  • Hyperglycaemia (requires insulin infusion)
  • Hypokalaemia
  • Fluid retention
  • Immunosuppression
  • GI bleeding (especially with NSAIDs)
  • Delirium (high doses)
  • Adrenal suppression on withdrawal

Interactions

  • Amphotericin B (additive hypokalaemia)
  • NSAIDs (increased GI bleeding)
  • Rifampicin (reduces steroid effect)
  • Antidiabetics (hyperglycaemia antagonism)

Monitoring

  • Blood glucose (4-hourly minimum)
  • Serum potassium
  • Vasopressor requirements (weaning marker)
  • Signs of secondary infection
