DISEASE-MODIFYING
THERAPIES FOR MS
Updated July 2021. Please visit nationalMSsociety.org/DMT for the most current
version of this publication.

Although a cure for MS has not yet been discovered, a number of medications (also
called disease modifying therapies, or DMTs) have been approved to treat MS.
Permanent damage to the central nervous system (or CNS, which is made up of the
brain, spinal cord and optic nerves) can occur early in the disease, even when a
person has no symptoms and feels well. Early and ongoing treatment with DMTs may
help prevent permanent damage in the CNS. Research has demonstrated the DMTs
for relapsing forms of MS reduce the frequency and severity of MS relapses, reduce
the development of new areas of damage in the CNS and slow the accumulation of
disability. Disease modifying therapies don’t generally improve everyday symptoms.
Many symptoms of MS can be managed using other types of medications and non-
medication strategies. Combining DMT use, symptom management and a healthy
lifestyle is the optimal strategy for managing MS.

Working with your healthcare provider to find the
best choice for you
The decision to take a DMT should be a shared decision made jointly between you
and your healthcare provider. Each person’s body or disease can respond to DMTs
differently, and the DMT that is the best option for one person may not be the best for
another person. In addition, a DMT that adequately controls your disease today may
not do so in the future and you may need to change to a different DMT. Also make
sure your provider knows what other health conditions and medications (including
vitamins and supplements) you take as that can affect which DMTs are safe for you.

Help with DMT costs
Learn more about patient assistance programs to help with the cost of each DMT at

Understanding US Food and Drug Administration
(FDA) warnings
The chart below summarizes the side effects, warnings and precautions listed for
each DMT in the FDA required prescribing information. In some instances, a warning
is printed in a black box in the prescribing information to call attention to serious or
life-threatening risks. All black box warnings are in bold font in the column outlining
the ‘Side effects and warnings’ in the chart.

Each DMT can cause a serious allergic reaction, and some make it unsafe for you to
receive certain vaccines while you’re taking them. Prior to starting any DMT, talk
with your healthcare provider about any vaccines you should get or have recently
received. Each DMT requires some safety monitoring. Talk with your healthcare
provider about the monitoring that is required for the DMT you are taking and be
consistent with it.

None of the DMTs are approved by the FDA for women who are pregnant or plan to
become pregnant, or who are breastfeeding. It is important for women to discuss
their plans for pregnancy with their healthcare provider so that they can decide
together the best and safest treatment plan.
