What Is Interferon Beta-1b Used For?

How Does Interferon Beta-1b Work?

Even though interferon beta-1b is made using bacteria, it is almost exactly the same as human interferon. Interferons are naturally occurring proteins or glycoproteins (proteins attached to carbohydrates). In humans, interferons are produced by cells in response to certain situations (such as viral infections) and often play a key role in the immune system.
At this time, it is not fully understood how interferon beta-1b works to treat MS. Although the exact causes of MS are not known, it is often considered to be an autoimmune disease in which the immune system attacks and destroys the protective coating around nerve fibers. It is thought that interferon beta-1b may work by limiting this immune system response, decreasing the damage to the nerves.
Because interferon beta-1b is a protein, it would be broken down and destroyed by the digestive system if taken by mouth. For this reason, interferon beta-1b must be injected to bypass the digestive tract.

Interferon Beta-1b Use in Children and Teens

Interferon beta-1b is not approved for individuals under 18 years old. Talk to your healthcare provider about the benefits and risks of using interferon beta-1b in children or teens.

Off-Label Interferon Beta-1b Uses

On occasion, your healthcare provider may recommend interferon beta-1b for something other than treating relapsing MS. This is called an "off-label" use. At this time, using the medication to treat other types of MS is considered an off-label interferon beta-1b use.
