Management of Steroid Withdrawal Syndrome
Corticosteroid withdrawal should follow a gradual decrease of doses over a period of at least 1 month to prevent withdrawal syndrome, with tapering not being too rapid to avoid recurrence or worsening of the underlying condition. 1
Understanding Steroid Withdrawal Syndrome
Steroid withdrawal syndrome can present with:
- Weakness, fatigue, loss of appetite
- Weight loss, nausea, vomiting
- Diarrhea and abdominal pain
- Myalgia (muscle pain) and arthralgia (joint pain)
- Mood changes, headache, fever
- Postural hypotension
This syndrome is under-recognized but occurs in approximately 50% of patients tested immediately after withdrawal of medium or high-dose prednisolone used for long periods 2. It can mimic the underlying disease being treated, making diagnosis challenging.
Risk Factors for Withdrawal Syndrome
- Duration of therapy >3 weeks
- Doses exceeding 7.5mg prednisolone equivalent daily
- Higher doses and longer duration correlate with more severe HPA axis suppression
- Abrupt discontinuation after prolonged use
- Pre-existing conditions such as cirrhosis increase risk of complications
Recommended Tapering Protocol
General Principles:
- Tapering should occur over at least 1 month 1
- Morning dosing is preferred to mimic natural cortisol rhythm 2
- Patients on long-term steroids should have a more gradual taper
Specific Tapering Schedule:
- Initial taper: Reduce from initial dose to 30mg daily for 5-7 days, then to 20mg daily for 5-7 days
- Intermediate taper: Reduce to 15mg daily for 5-7 days, then to 10mg daily for 5-7 days
- Final taper: Reduce to 7.5mg daily for 5-7 days, then to 5mg daily for 5-7 days, and finally to 2.5mg daily for 5-7 days before discontinuation 2
For patients on dexamethasone, a more gradual tapering is recommended due to higher risk of withdrawal symptoms (75% vs 51.4% with prednisone) 3.
Monitoring During Tapering
Regular clinical assessment for:
- Signs of the underlying disease reactivation
- Symptoms of adrenal insufficiency (fatigue, weakness, dizziness, nausea, hypotension)
- Psychiatric symptoms (mood changes, depression)
Laboratory monitoring as needed:
- Blood pressure measurements
- Serum electrolytes, particularly potassium 4
- Morning cortisol levels if adrenal insufficiency is suspected
Special Considerations
Stress Dosing
- Patients may require increased steroid doses during periods of stress (surgery, trauma, severe illness) both during treatment and for up to a year afterward 4
- Patients should carry medical identification indicating steroid dependence 4
Calcium and Vitamin D Supplementation
- All patients receiving corticosteroids should receive 800-1000 mg/day calcium and 800 IU/day vitamin D 1
- This can be achieved through oral supplements or dietary intake (for calcium) while on corticosteroids
Management of Persistent Withdrawal Symptoms
If withdrawal symptoms persist despite appropriate tapering:
- Temporarily increase the dose of glucocorticoid replacement therapy 5
- Resume the previous stable dose and attempt a slower taper
- Consider alternate-day therapy as a maintenance program for patients requiring high-dose glucocorticoid therapy over a prolonged period 6
Duration of Management
- The median duration of steroid withdrawal syndrome is approximately 10 months (range 6-10 months) 5
- Patients who have received 1-4 weeks of suppressive steroid treatment should be considered at risk for HPA axis dysfunction in stressful situations for up to one year 7
Prevention Strategies
- Use the lowest effective dose for the shortest duration possible
- Consider alternate-day therapy when appropriate
- Provide patient education about the importance of not stopping steroids abruptly
- Ensure adequate calcium and vitamin D intake
- Implement lifestyle modifications (regular physical exercise, smoking cessation) 1
Remember that steroid withdrawal syndrome is self-limiting and can be effectively managed with appropriate tapering and temporary increases in glucocorticoid replacement therapy when needed.
