What is the appropriate steroid tapering regimen for patients with different medical conditions, such as asthma or rheumatoid arthritis, who have been taking prednisone (corticosteroid) for an extended period?

Steroid Tapering for Different Medical Conditions

General Principles

For patients on corticosteroids longer than 3 weeks, gradual tapering is mandatory to prevent adrenal insufficiency, while courses under 3-4 weeks can be stopped abruptly without tapering. 1, 2

Key Physiologic Considerations

• Hypothalamic-pituitary-adrenal (HPA) axis suppression should be anticipated in any patient receiving more than 7.5 mg prednisone daily for more than 3 weeks. 1
• Single daily morning dosing (before 9 AM) is preferred to minimize adrenal suppression, except when prominent night pain occurs on low doses (<5 mg daily). 1, 3
• Patients remain vulnerable to adrenal crisis during tapering and for up to 12 months after discontinuation. 1, 4

Tapering Algorithms by Initial Dose

High-Dose Tapering (>30 mg/day)

For patients starting above 30 mg/day, reduce by 5-10 mg every 1-2 weeks until reaching 10 mg/day, then slow dramatically to 1 mg every 4 weeks. 4, 5

Specific schedule:

• Weeks 1-8: Reduce from starting dose to 10 mg/day by decreasing 5-10 mg every 1-2 weeks 5
• Below 10 mg/day: Reduce by 1 mg every 4 weeks until discontinuation 1, 4
• Alternative for very slow taper: Use alternate-day dosing (e.g., 10/7.5 mg on alternating days) when below 10 mg 4, 5

Medium-Dose Tapering (10-30 mg/day)

Taper by 5 mg weekly until reaching 10 mg/day, then slow to 2.5 mg every 2-4 weeks until reaching 5 mg/day, then 1 mg every 4 weeks. 4

Low-Dose Tapering (<10 mg/day)

For patients on long-term low-dose therapy, reduce by 1 mg every 4 weeks until discontinuation. 1, 4

If 1 mg tablets unavailable, use alternate-day schedules:

• Example: 5 mg and 4 mg on alternating days for 4 weeks, then 4 mg daily 1, 4

Disease-Specific Tapering Protocols

Polymyalgia Rheumatica (PMR)

Start with 12.5-25 mg prednisone daily, reduce to 10 mg/day within 4-8 weeks, then taper by 1 mg every 4 weeks until discontinuation. 1

• Initial dose selection: Use 25 mg for high relapse risk/low adverse event risk; use 12.5 mg for patients with diabetes, osteoporosis, or glaucoma 1
• Intramuscular methylprednisolone (120 mg every 3 weeks initially) may be considered for women with difficult-to-control hypertension, diabetes, osteoporosis, or glaucoma 1

Giant Cell Arteritis

Initial dose 40-60 mg/day, taper to 15-20 mg/day within 2-3 months, then to ≤5 mg/day after 1 year. 4

Inflammatory Myopathies

Start with 0.5-1 mg/kg/day (typically 60-80 mg/day) and follow this structured taper: 4

• Reduce by 10 mg every 2 weeks until reaching 30 mg/day
• Reduce by 5 mg every 2 weeks until reaching 20 mg/day
• Reduce by 2.5 mg every 2 weeks until reaching 10 mg/day
• At 10 mg/day, slow to 1 mg every 2-4 weeks until completed

Autoimmune Hepatitis

For adults: Start with 30 mg/day with azathioprine, taper to 10 mg/day for maintenance. 4

When azathioprine is established (after 2-3 months):

• Reduce by 5 mg weekly until reaching 10 mg/day 4
• Then reduce by 2.5 mg every 2-4 weeks 1, 4
• Monitor aminotransferases monthly during tapering 4

For children: Start with 1-2 mg/kg/day (up to 60 mg/day), taper over 6-8 weeks to 0.1-0.2 mg/kg daily or 5 mg daily. 4

Inflammatory Bowel Disease (IBD)

Patients on prolonged corticosteroids must have a tapering course when stopping and should be warned about steroid withdrawal syndrome (weakness, nausea, arthralgia). 1

Acute Asthma Exacerbations

For acute asthma requiring hospitalization, a 7-10 day course of 40 mg prednisone daily can be stopped abruptly without tapering—tapering provides no benefit and increases side effects. 6, 7

• This applies specifically to acute exacerbations in patients not on chronic steroids 6, 7
• Research shows no difference in relapse rates between 1-week and 7-week tapers (41% vs 52%) 7
• HPA axis recovers within 1 week after short burst therapy 8

Rheumatoid Arthritis (RA)

For long-term low-dose therapy in RA, do not exceed 10 mg/day, often given as 5 mg twice daily, and taper by 1 mg every 2-4 weeks. 9

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. 1, 4, 5

• Consider adding steroid-sparing agents (methotrexate 7.5-10 mg/week) if multiple relapses occur 4, 5
• For autoimmune hepatitis, ensure azathioprine dose is adequate (2 mg/kg/day) before aggressive steroid reduction 4

Stress Dosing Requirements

During acute illness or physiologic stress while tapering or within 12 months of discontinuation, patients require supplemental glucocorticoids. 1, 4

Practical stress dosing:

• For patients on 10 mg prednisone daily: Increase to hydrocortisone 50 mg twice daily for 3 days during acute stress 4
• For patients on high-dose therapy: Use hydrocortisone 50 mg three times daily during acute illness 4
• For minor illness: Double the current prednisone dose for 3 days 4

Monitoring During Tapering

Follow-up visits every 4-8 weeks during the first year of tapering, then every 8-12 weeks thereafter. 4, 5

At each visit, monitor for:

• Blood pressure, glycemic control, and serum potassium 1
• Disease activity markers (ESR, CRP for inflammatory conditions) 4
• Signs of adrenal insufficiency (fatigue, weakness, nausea, hypotension) 1
• Body weight, peripheral edema, cardiac insufficiency 1
• Serum lipids, blood/urine glucose, ocular pressure 1

Prophylaxis Against Steroid-Related Complications

For patients on prednisone >7.5 mg daily for more than 3 months, prescribe calcium and vitamin D supplementation. 1

Bone protection:

• Calcium 800-1000 mg/day and vitamin D 400-800 units/day 1, 9
• Bisphosphonates based on risk factors and bone mineral density (T-score threshold -1.5 for IBD patients) 1
• Consider annual IV zoledronic acid for malabsorption or GI intolerance 1

Gastric protection:

• Proton pump inhibitors or misoprostol for patients on concurrent NSAIDs 1

Infection prophylaxis:

• Vaccinations as for immunomodulatory therapy 1
• Consider co-trimoxazole 960 mg three times weekly for patients on ≥20 mg prednisolone with triple therapy 1

Critical Pitfalls to Avoid

The most common error is tapering too quickly, especially below 10 mg/day, which leads to disease flare or symptomatic adrenal insufficiency. 4, 5

• Never use 5 mg weekly reductions after 2 months of therapy—this is only appropriate for short courses 4
• Do not accelerate taper if steroid-sparing agents started less than 2-3 months ago—therapeutic levels may not be established 4
• Never stop steroids abruptly after more than 3-4 weeks of therapy—this risks adrenal crisis 1, 2
• Failing to provide stress dosing education increases risk of adrenal crisis during intercurrent illness 1, 4
• Not monitoring disease activity during tapering may miss early signs of relapse 4

Patient Education Essentials

All patients on chronic glucocorticoids should receive:

• Written tapering schedule and clear instructions 1
• Education on stress dosing for sick days 1, 4
• Warning about steroid withdrawal syndrome (weakness, nausea, arthralgia) 1
• Glucocorticoid card documenting start date, initial dose, and tapering regimen 1
• Consider medical alert bracelet for adrenal insufficiency 4
• Information accessible to general practitioners on managing intercurrent illnesses 1
