Oral Corticosteroid Pregnancy: Compatible for significant indications — crosses placenta minimally (prednisolone metabolised to inactive form by placenta); monitor for neonatal adrenal insufficiency

Prednisolone (Oral — General Medicine)

Brand names: Prednisolone (generic)

Adult dose

Dose: Inflammatory/autoimmune conditions: 30–60 mg OD initially (or as per condition-specific protocol). Reduce by 5–10 mg every 1–2 weeks when improving. Maintenance: lowest effective dose.
Route: Oral
Frequency: Once daily in the morning (with food)
Max: 60–80 mg/day (acute high-dose); 5–15 mg/day maintenance
Always prescribe 'Prednisolone' — do not use 'steroids' alone on prescriptions. Prescribe with gastric protection (PPI) if at risk of peptic ulcer. Bone protection if >3 months use (bisphosphonate).

Paediatric dose

Dose: 1 mg/kg
Route: Oral
Frequency: OD–BD
Max: 60 mg/day
Concentration: 1 mg/mL or 5 mg/mL oral solution mg/ml
Asthma exacerbation: 1–2 mg/kg/day (max 40 mg) for 3–5 days. Nephrotic syndrome: 60 mg/m²/day or 2 mg/kg/day.

Dose adjustments

Renal

No dose adjustment required; may cause fluid retention in renal failure

Hepatic

Caution — increased risk of infection; active hepatitis is a relative contraindication without antiviral cover

Paediatric weight-based calculator

Asthma exacerbation: 1–2 mg/kg/day (max 40 mg) for 3–5 days. Nephrotic syndrome: 60 mg/m²/day or 2 mg/kg/day.

Clinical pearls

  • Sick day rules: never suddenly stop after >3 weeks use — adrenal suppression. Reduce gradually.
  • Bone protection: start bisphosphonate (alendronate) + calcium/vitamin D if course >3 months anticipated (FRAX-guided)
  • Steroid card: carry blue steroid card during any course >3 weeks or doses equivalent to >6 mg prednisolone/day
  • Hyperglycaemia: check random blood glucose after starting; may unmask T2DM or require insulin adjustment

Contraindications

  • Active systemic fungal infection (without antifungal cover)
  • Live vaccines contraindicated with immunosuppressive doses

Side effects

  • Hyperglycaemia (steroid-induced diabetes)
  • Hypertension
  • Weight gain/moon face/truncal obesity
  • Osteoporosis (long-term)
  • Adrenal suppression
  • Psychiatric effects (mania, depression, psychosis)
  • GI bleeding
  • Cataracts (long-term)
  • Increased infection susceptibility
  • Growth suppression (children)

Interactions

  • NSAIDs — additive GI bleeding risk
  • Anticoagulants — variable effect on INR (monitor)
  • Rifampicin — reduces prednisolone levels
  • Live vaccines — contraindicated
  • ACEi — hyperkalaemia risk
  • Antidiabetics — higher doses required

Monitoring

  • Blood glucose
  • Blood pressure
  • Weight
  • Bone density (long-term — DEXA)
  • Eye pressure (prolonged high-dose — glaucoma risk)
  • Signs of infection
  • Growth in children
