Betaferon
How does it work?
This injection contains interferon beta-1b. Interferons are a family of small protein molecules that are produced and secreted by cells in response to viral infections or various synthetic and biological inducers. Three major classes of interferons have been identified: alfa, beta and gamma. They work in a complicated way that is not fully understood, but are thought to boost the immune system, causing it to attack infected or cancerous cells. Interferon beta is used to treat multiple sclerosis. In some patients multiple sclerosis follows a course of relapse and remission, where symptoms worsen for a while then improve before worsening again. It is these patients who can benefit from interferon beta, which helps to reduce the frequency and severity of the relapses. As interferon beta is not effective in all patients with multiple sclerosis, and because it can have significant side effects, it is recommended that all paitents are assessed by a neurologist before starting treatment. Frequent blood tests are also needed to monitor the interferon's effect on blood composition and liver function.
