Prednisone Tapering Protocol
For most clinical situations, taper prednisone gradually using a dose-dependent approach: reduce by 5-10 mg weekly until reaching 10 mg/day, then slow to 1 mg every 4 weeks until discontinuation, with single morning dosing before 9 AM. 1, 2
Key Principles of Tapering
Single daily morning dosing (before 9 AM) is strongly preferred to align with the body's natural cortisol rhythm and minimize HPA axis suppression. 1, 3 The only exception is for prominent night pain while tapering below 5 mg daily, where divided dosing may be considered. 4
Duration of therapy determines tapering necessity:
- Courses <3 weeks: No taper required for most patients 1
- Courses >3 weeks: Gradual taper mandatory to prevent adrenal insufficiency 1, 2
Specific Tapering Schedules by Dose Range
High-Dose Tapering (>30 mg/day)
Initial rapid reduction phase:
Example for 40 mg starting dose:
- Week 1-2: 40 mg daily
- Week 3: 30 mg daily
- Week 4: 25 mg daily
- Week 5: 20 mg daily
- Week 6: 15 mg daily
- Week 7-8: 10 mg daily 1
Medium-Dose Tapering (10-30 mg/day)
Moderate reduction phase:
- Reduce by 5 mg every 1-2 weeks until reaching 10 mg/day 1, 2
- Then transition to slow taper protocol 2
Low-Dose Tapering (<10 mg/day)
Slow reduction phase (most critical):
- Reduce by 1 mg every 4 weeks until discontinuation 4, 1
- Alternative: Use 1.25 mg decrements with alternate-day schedules (e.g., 10/7.5 mg alternating days) if 1 mg tablets unavailable 2
Example taper from 10 mg:
- Weeks 1-4: 10 mg daily
- Weeks 5-8: 9 mg daily
- Weeks 9-12: 8 mg daily
- Continue reducing 1 mg every 4 weeks to zero 1, 2
Disease-Specific Modifications
Polymyalgia Rheumatica
- Initial dose: 12.5-25 mg daily (never exceed 30 mg) 4
- Taper to 10 mg within 4-8 weeks 4
- Then 1 mg every 4 weeks until discontinuation 4
Immune-Related Adverse Events (Checkpoint Inhibitors)
- Grade 2-3: Start 0.5-1 mg/kg/day 4
- Grade 3-4: Start 1-2 mg/kg/day 4
- Taper over 4-6 weeks once symptoms improve to grade ≤1 4
- Resume immunotherapy only when tapered to ≤10 mg/day and symptom-free 4
Autoimmune Hepatitis with Azathioprine
When azathioprine established (>2-3 months):
- Reduce by 5 mg weekly until 10 mg/day 2
- Then reduce by 2.5 mg every 2-4 weeks 2
- Monitor aminotransferases monthly during taper 2
Managing Relapse During Tapering
If symptoms recur at any point:
- Immediately return to the previous effective (pre-relapse) dose 4, 1
- Maintain that dose for 4-8 weeks until disease control re-established 4, 2
- Attempt slower taper (e.g., reduce by 1 mg every 6-8 weeks instead of 4 weeks) 1, 2
- Consider adding steroid-sparing agents if multiple relapses occur 2
Monitoring Requirements
During tapering, monitor for:
- Disease flare: Worsening of original symptoms, increased inflammatory markers 1, 2
- Adrenal insufficiency: Fatigue, weakness, dizziness, nausea, hypotension 1, 2
Follow-up schedule:
Stress Dosing Requirements
Patients require supplemental glucocorticoids during acute illness or stress:
- For minor illness: Double current prednisone dose for 3 days 1, 2
- For major stress/surgery: Hydrocortisone 50 mg 2-3 times daily 2
- This applies during tapering and up to 12 months after discontinuation 2
Special Population Considerations
Diabetes
- Require more frequent blood glucose monitoring throughout taper 1
- Consider lower initial doses when possible 1
Osteoporosis/Fracture Risk
- Consider lower initial doses in severe osteoporosis 1
- Ensure calcium 800-1000 mg/day and vitamin D 400-800 units/day 5
Elderly Patients
- Consider lower initial doses (10-20 mg daily for inflammatory conditions) 1
- May require slower taper rates 1
Critical Pitfalls to Avoid
Tapering too quickly is the most common error and leads to disease flare or symptomatic adrenal insufficiency. 1, 2 When in doubt, taper more slowly. 1
Underdosing at initiation: Standard methylprednisolone dose packs provide inadequate steroid exposure; for acute inflammatory conditions, use 40-60 mg daily initially. 1
Failing to provide written instructions: Patients must receive explicit daily dosing for each phase of the taper to ensure adherence. 1
Accelerating taper before steroid-sparing agents are established: If using azathioprine or other immunosuppressants, wait 2-3 months for therapeutic levels before aggressive steroid reduction. 2
Not educating patients about stress dosing: Patients must understand when and how to increase doses during illness, and consider medical alert bracelet for adrenal insufficiency. 2
Short-Course Exception
For acute conditions treated <3 weeks: A simple taper of 40 mg daily for 3-4 days, then reducing by 5 mg every 2-3 days until completion is appropriate. 1 Research shows that very short courses (7-10 days) for acute asthma may not require tapering at all. 6, 7
