13-Day Prednisone Taper Protocol
For a 13-day prednisone course, administer full-dose prednisone (typically 1 mg/kg/day, maximum 60 mg) for 7 days, then reduce by 10 mg every 2 days until completion. This provides approximately 540 mg total prednisone over the 13-14 day period and is the standard approach for acute inflammatory conditions requiring short-term high-dose intervention 1.
Specific Dosing Schedule
For a typical 60 mg starting dose:
- Days 1-7: 60 mg daily (single morning dose)
- Days 8-9: 50 mg daily
- Days 10-11: 40 mg daily
- Days 12-13: 30 mg daily
This schedule can be extended to 14 days by continuing the taper (20 mg on days 14-15,10 mg on days 16-17) if needed 1.
Critical Administration Principles
Administer as a single morning dose before 9 am to minimize HPA axis suppression and align with the body's natural cortisol peak between 2-8 am 2.
Take with food or milk to reduce gastric irritation 2.
No formal taper is required for courses ≤2 weeks when using this protocol, as adrenal insufficiency is not a significant concern with short courses 1, 3.
Evidence Supporting This Approach
The American Academy of Otolaryngology-Head and Neck Surgery specifically validates this 13-14 day regimen with 7 days of full-dose therapy followed by 10 mg reductions every 2 days 1. This approach provides adequate anti-inflammatory effect while minimizing adverse events.
Research demonstrates that tapering may be unnecessary for short courses (≤2-3 weeks), as multiple studies in acute asthma found no difference in relapse rates between tapered and non-tapered courses 4, 5. However, the gradual reduction approach remains standard practice for patient comfort and symptom control.
Common Pitfalls to Avoid
Do not use methylprednisolone dose packs as equivalent therapy - they provide only 105 mg prednisone equivalent total, which is grossly inadequate compared to the 540 mg needed 1.
Ensure the initial dose reaches 1 mg/kg/day (typically 60 mg for adults) to avoid underdosing and compromised efficacy 1.
Monitor for hyperglycemia and weight gain, the most frequent adverse events even in short courses 1.
Do not abruptly discontinue without following the taper schedule, as this may lead to symptom rebound even though adrenal insufficiency is unlikely 2.
Alternative Considerations
If the patient has been on corticosteroids for >3 weeks previously or has other risk factors for HPA axis suppression, a slower taper may be warranted. However, for a standard 13-day course in a steroid-naive patient, the rapid taper described above is appropriate and evidence-based 1, 3.
