Multiple sclerosis (MS) is an unpredictable disorder that can cause a variety of symptoms, which for many, can flare-up and then subside over the course of days, months, or even years. Most individuals are initially diagnosed with one of the relapsing forms of MS, causing these flare-ups. A much smaller percentage of individuals begin with one of the progressive forms, exhibiting a more steady progression of symptoms. For details on types of MS, please visit Types of Multiple Sclerosis | MSAA.

The treatments for multiple sclerosis (MS) are divided into three main categories:

A Quick Overview of Long-Term Treatments for MS

  • Although initially approved only for the treatment of relapsing forms of MS in adults, disease-modifying therapies (DMTs) are now available for progressive forms as well as for clinically isolated syndrome (CIS), and for pediatric MS.
  • DMTs were developed to slow disease activity. They work by reducing the number and severity of relapses, reducing areas of inflammation within the central nervous system (CNS) as seen on magnetic resonance imaging (MRI) scans, and delaying disease progression and/or disability.
  • Depending on the specific DMT prescribed, the medication may be given via self-injection, intravenous (IV) infusion, or by oral administration.
  • When appropriate, most neurologists recommend starting a DMT as soon as possible after diagnosis.

A Quick Overview of Treating MS Relapses

  • Treating relapses helps to control the sudden flare-up of symptoms, also referred to as exacerbations or attacks.
  • Relapses usually range in length from a few days to a few months before subsiding.
  • While treatments may shorten the length of the relapse and lessen its severity, treating a relapse does not appear to affect the long-term progression of the disease or its symptoms – although studies continue to evaluate the long-term outcomes of treating relapses.
  • The first line of treatment for moderate to severe relapses is typically a course of high-dose steroids given intravenously (IV) over a period of three to five days. As an alternative to IV steroids, treatment for a moderate to severe relapse also includes an equivalent, high-dose, oral regimen of steroids.
  • Mild relapses not impacting one’s ability to perform daily activities are often treated using symptom-management medications and strategies, reserving steroid treatments for more significant relapses.

A Quick Overview of Treating the Symptoms of MS

  • Symptom management is another important area in the overall treatment of MS. Symptoms vary greatly from one individual to another, and each symptom needs to be addressed by a healthcare professional.
  • Common symptoms range from fatigue, weakness, and reduced mobility, to visual problems, numbness, and bladder issues. For a full list of common symptoms, please visit MSAA’s Symptom Listing [link].
  • In addition to medications prescribed for a specific symptom, other treatment therapies – such as rehabilitation, counseling, and exercise, for example – may be recommended by the healthcare team to increase the effectiveness of managing certain symptoms.
  • Most of the medications used to treat symptoms are available by prescription only, but even with over-the-counter medications, those considering making a change to their present regimen should consult a physician.
  • Women who are pregnant or planning to become pregnant need to discuss any medications they are taking and any new medications they are considering with their doctor.
