From the Research

The first-line treatment for a multiple sclerosis (MS) flare is high-dose corticosteroids, typically methylprednisolone administered orally at 1000 mg daily for 3-5 days, as this route has been shown to be as effective as intravenous administration in recent studies 1.

Key Considerations

  • The treatment goal is to reduce inflammation and suppress immune system activity, thereby resolving the acute inflammation in the central nervous system during an MS flare.
  • Corticosteroids can shorten the duration of symptoms and accelerate recovery, though they do not affect the long-term course of the disease.
  • Common side effects include insomnia, metallic taste, facial flushing, increased appetite, and elevated blood glucose levels.
  • Patients should be monitored for mood changes, infection risk, and stomach irritation.

Treatment Approach

  • Treatment should begin promptly after confirming a true relapse, characterized by new or worsening neurological symptoms lasting more than 24 hours in the absence of fever or infection.
  • Oral methylprednisolone or high-dose oral prednisone (1250 mg daily for 3-5 days) can be used as alternatives to intravenous corticosteroids, with similar efficacy and safety profiles 2, 1.
  • The choice between oral and intravenous routes may depend on individual patient factors, such as the severity of symptoms and the risk of complications.

Evidence Base

  • Recent studies have demonstrated the effectiveness and safety of oral corticosteroids for treating MS relapses, with no significant differences in clinical outcomes compared to intravenous administration 2, 1.
  • The use of oral corticosteroids may be particularly beneficial during the COVID-19 pandemic, as it reduces the need for hospitalization and minimizes the risk of viral exposure 1.
