Intravenous methylprednisolone is considered the preferred steroid for treating acute multiple sclerosis (MS) relapses due to its rapid onset, high potency, and effectiveness in reducing inflammation. Here’s why:

1. Rapid Action: Administered intravenously, methylprednisolone bypasses the digestive system, allowing for immediate absorption into the bloodstream and faster delivery to inflamed areas in the central nervous system.
2. Potent Anti-Inflammatory Effect: Methylprednisolone is a powerful corticosteroid that suppresses the immune response, reducing inflammation and edema in the brain and spinal cord caused by MS relapses. This helps alleviate symptoms like weakness, numbness, or vision problems.
3. Evidence-Based Efficacy: Clinical studies, such as those referenced in MS treatment guidelines (e.g., from the National Multiple Sclerosis Society), show that high-dose IV methylprednisolone (typically 500–1000 mg/day for 3–5 days) significantly shortens the duration and severity of MS relapses compared to oral steroids or placebo.
4. Minimized Systemic Side Effects: While not free of side effects (e.g., mood changes, insomnia, or gastrointestinal upset), the short duration of high-dose IV therapy limits prolonged exposure compared to longer-term oral steroid regimens, reducing risks like osteoporosis or weight gain.
5. Standardized Protocol: IV methylprednisolone is the gold standard in MS relapse management, as it has been extensively studied and is part of established treatment protocols globally, ensuring consistent dosing and outcomes.

Comparison to Other Steroids: Oral prednisone or dexamethasone may be used in some cases, but they are less preferred. Oral steroids have slower absorption and may require higher cumulative doses, potentially increasing side effects. IV methylprednisolone’s direct delivery and standardized high-dose regimen make it more effective for acute MS flares.

Note: It’s not a cure for MS, and it doesn’t alter long-term disease progression. It’s specifically used for acute relapses. Always consult a neurologist for personalized treatment decisions.
