Prednisone 20 mg Taper Over Two Weeks
For a two-week prednisone taper starting at 20 mg daily, reduce to 10 mg daily after one week (days 1-7: 20 mg, days 8-14: 10 mg), then discontinue. This represents the most practical approach for a short-course steroid taper when the clinical context doesn't require prolonged therapy 1.
Rationale and Evidence Base
The FDA labeling emphasizes that dosage requirements must be individualized based on disease severity and patient response, with the fundamental principle being gradual dose reduction in small increments at appropriate intervals 1. For short-term therapy, the evidence supports:
Week 1 (Days 1-7): 20 mg daily
- Maintain initial dose to achieve therapeutic effect
- Take in the morning (before 9 AM) to minimize HPA axis suppression 1
- Administer with food or milk to reduce gastric irritation
Week 2 (Days 8-14): 10 mg daily
- Reduce by 50% after one week
- Continue morning dosing
- This allows for gradual HPA axis recovery while maintaining some anti-inflammatory effect
Context from Disease-Specific Guidelines
While your question doesn't specify the underlying condition, the evidence shows varying taper approaches depending on indication:
Polymyalgia rheumatica: Guidelines recommend tapering from initial doses to 10 mg within 4-8 weeks, then by 1 mg every 4 weeks 2. However, this is for higher initial doses (12.5-25 mg range).
Autoimmune hepatitis: Uses more aggressive initial dosing (30 mg reducing to 10 mg over 4 weeks) 3, 4, but this is for chronic management requiring months of therapy.
Immune checkpoint inhibitor toxicity: For grade 2 adverse events, uses 0.5-1 mg/kg with 4-6 week tapers once improved 5.
Critical Safety Considerations
Never abruptly discontinue prednisone - the FDA labeling explicitly warns against abrupt withdrawal after any duration of therapy 1. Even a two-week course warrants tapering, though the risk of HPA suppression is lower than with prolonged therapy.
Additional Protective Measures:
- Consider PPI for GI prophylaxis if risk factors present
- Counsel patient on signs of adrenal insufficiency (fatigue, weakness, hypotension)
- Advise to contact you if stressful situations arise during or shortly after taper
- Take with food to minimize gastric irritation
Alternative Approach for Higher-Risk Patients
If the patient has comorbidities (diabetes, osteoporosis, hypertension) or concerns about steroid toxicity, consider a more gradual taper:
- Days 1-5: 20 mg daily
- Days 6-9: 15 mg daily
- Days 10-12: 10 mg daily
- Days 13-14: 5 mg daily
This provides four dose reductions over 14 days rather than one, which may be safer in vulnerable populations, though it extends slightly beyond two weeks to complete discontinuation.
Monitoring
Watch for:
- Symptom recurrence indicating inadequate taper speed
- Steroid withdrawal symptoms (fatigue, myalgias, arthralgias) indicating too-rapid taper
- Hyperglycemia in diabetics or at-risk patients
- Blood pressure elevation
The two-week timeframe you've specified is relatively short for steroid therapy, suggesting either acute self-limited disease or a bridge to other therapy. The simple 20 mg × 7 days → 10 mg × 7 days → stop approach balances efficacy with safety for most clinical scenarios requiring brief steroid courses.
