Initial Treatment Orders for Multiple Sclerosis Relapse
High-dose methylprednisolone (1000 mg daily for 3 days) is the first-line treatment for MS relapse, with oral administration being as effective as intravenous administration and should be initiated immediately upon diagnosis of a relapse. 1
Corticosteroid Therapy
First-Line Treatment
- Methylprednisolone dosing options:
- Oral methylprednisolone: 1000 mg once daily for 3 days
- Intravenous methylprednisolone: 1000 mg once daily for 3 days
- Both routes have equivalent efficacy for improvement of disability scores at 1 month 1
Administration Considerations
- Oral administration advantages:
Monitoring During Treatment
- Monitor for common adverse effects:
- Insomnia (more common with oral administration - 77% vs 64% for IV) 1
- Mood changes
- Increased appetite
- Gastrointestinal disturbances
MRI Assessment
Baseline MRI recommended with the following sequences 3:
- T2-weighted FLAIR sequences
- T2-weighted fast/turbo spin echo sequences
- Gadolinium-enhanced T1-weighted sequences
- Diffusion-weighted imaging (for patients at risk of PML)
Technical considerations 3:
- Field strength of at least 1.5T
- Slice thickness no more than 3mm
- Consistent positioning between scans
Adjunctive Treatments to Consider
For Severe Relapses
- Plasma exchange may be considered as adjunctive therapy in severe cases not responding to high-dose corticosteroids 3
For Specific Symptoms
- Symptomatic management based on presenting symptoms:
- Spasticity management
- Pain control
- Bladder/bowel dysfunction management
- Fatigue management
Clinical Assessment
- Document baseline Expanded Disability Status Scale (EDSS) score
- Schedule follow-up assessment at 4 weeks post-treatment to evaluate response 1
- Consider combining EDSS with Multiple Sclerosis Functional Composite (MSFC) for better sensitivity 3
Important Considerations
Timing of Treatment
- Initiate treatment as soon as possible after relapse diagnosis
- Early treatment (within first 2-10 years of symptom onset) is critical to prevent long-term disability 3
Patient Education
- Inform patients about expected side effects
- Advise on the importance of completing the full course of treatment
- Discuss disease-modifying therapy options if not already on treatment
Pitfalls to Avoid
- Delaying treatment - Early intervention is critical to prevent long-term disability
- Underestimating subclinical disease activity - Regular monitoring with MRI is important even in the absence of clinical symptoms 3
- Inadequate follow-up - Schedule appropriate follow-up to assess treatment response
- Neglecting to assess for disease-modifying therapy - Relapse indicates active disease and may warrant initiation or change of disease-modifying therapy
The evidence strongly supports that oral high-dose methylprednisolone is non-inferior to intravenous administration for MS relapses, making it a practical and effective option that can be initiated immediately upon diagnosis of a relapse 1, 4.
