Interferons for Secondary Progressive MS

Does this apply to me?

When deciding if this information applies to you it’s helpful to think about how similar you are to the people that were included in the studies.

What we know about the people included in the Interferons studies:

  • They had secondary progressive MS

If I am similar to the people in the studies, can I expect the same results?

It is important to remember that studies deal with averages and statistics. Even if you are a person with secondary progressive MS, we can’t know for sure that you will respond in the same way.

What we can say, is that, on average, people who have secondary progressive MS do not appear to benefit from taking interferons in terms of preventing worsening disability. However, people with SPMS, who still get relapses, may experience a reduction in relapses.

If you have other kinds of MS, please see our other summaries on the effects of interferons in people with clinically isolated syndrome (CIS) (coming soon), relapsing remitting MS (RRMS) and primary progressive MS (PPMS).
