Prednisone Tapering Recommendations
When Tapering is NOT Necessary
For prednisone courses lasting less than 3 weeks, no taper is required—simply stop the medication abruptly. 1
- Courses of 3-10 days do not require tapering, as HPA axis suppression is minimal and adrenal insufficiency risk is negligible 1
- The threshold for mandatory tapering is typically doses ≥20 mg/day for more than 3-4 weeks 1
- Research confirms no difference in relapse rates or adrenal suppression between tapered and non-tapered courses in acute asthma treated for 7-10 days 2, 3, 4, 5
Critical exception: Patients with prior chronic corticosteroid use within the past year may have residual HPA axis suppression and require tapering even for short courses 1
Tapering Schedule for Long-Term High-Dose Therapy
High Initial Doses (>30 mg/day)
Reduce to 10 mg/day within 4-8 weeks, then decrease by 1 mg every 4 weeks until discontinuation. 6
- For doses >30 mg/day: Taper by 5 mg every week until reaching 10 mg/day 6
- Once at 10 mg/day: Slow the taper to 2.5 mg/week until reaching 5 mg/day 6
- Below 5 mg/day: Reduce by 1 mg every 4 weeks 6
Medium Initial Doses (10-30 mg/day)
- Taper by 5 mg every week until reaching 10 mg/day 6
- Then reduce by 2.5 mg/week until reaching 5 mg/day 6
- Below 5 mg/day: Decrease by 1 mg every 4 weeks 6
Low Doses (<10 mg/day)
For patients on long-term low-dose prednisone (≤10 mg/day), taper by 1 mg every 4 weeks until discontinuation. 6
- If 1 mg tablets are unavailable, use alternate-day dosing schedules (e.g., 10/7.5 mg alternate days) to achieve gradual reductions 6
- Monitor disease activity every 4-8 weeks during the first year of tapering, then every 8-12 weeks thereafter 6
Special Considerations for Patients on Steroid-Sparing Agents
When azathioprine has been established for 2-3 months, you can accelerate the taper more aggressively. 6
- Reduce prednisone by 5 mg every week until reaching 10 mg/day (faster than standard tapering) 6
- Once at 10 mg/day, taper by 2.5 mg every 2-4 weeks 6
- Monitor aminotransferases monthly during this accelerated phase to detect disease flare 6
- Do not accelerate if azathioprine started less than 2-3 months ago, as therapeutic levels may not be established 6
Managing Relapse During Tapering
If disease flare occurs, immediately return to the pre-relapse dose and maintain for 4-8 weeks before attempting a slower taper. 6
- Gradually decrease within 4-8 weeks to the dose at which relapse occurred 6
- Consider adding steroid-sparing agents if multiple relapses occur 6
- The most common error is tapering too quickly, leading to disease flare or symptomatic adrenal insufficiency 6
Stress Dosing Requirements
Patients require supplemental glucocorticoids during acute illness or physiologic stress while tapering or within 12 months of discontinuation. 6
- For patients on 10 mg prednisone daily: Increase to hydrocortisone 50 mg twice daily for 3 days during acute stress 6
- For patients on high-dose therapy: Use hydrocortisone 50 mg three times daily during acute illness 6
- For minor illness: Double the current prednisone dose for 3 days 6
- Consider a medical alert bracelet for adrenal insufficiency 6
Administration Principles
Administer prednisone as a single morning dose before 9 AM to minimize HPA axis suppression. 7
- Single daily dosing is preferred over divided doses except for prominent night pain on low doses (<5 mg daily) 6
- Take before, during, or immediately after meals to reduce gastric irritation 7
- HPA axis suppression should be anticipated in any patient receiving >7.5 mg daily for >3 weeks 6
Common Pitfalls to Avoid
- Tapering too quickly leads to disease flare or adrenal insufficiency 6
- Failing to monitor for steroid-related side effects during tapering 6
- Not providing patients with clear instructions about tapering schedule and signs of adrenal insufficiency 6
- Inappropriately extrapolating long-term tapering guidelines to short courses (<3 weeks) 1
- Underdosing with inadequate initial therapy (e.g., using methylprednisolone dose packs that provide only 105 mg prednisone equivalent) 8
