Extavia Description
This medication is used to treat multiple sclerosis. Interferon is not a cure for multiple sclerosis, but it may help to decrease the number of attacks of weakness and slow the worsening of the disease.
This medication is the same as a protein that your body naturally produces (interferon). In the body, it is thought to work by affecting the body's natural defenses (immune system) in many ways. Adding more interferon may help your body fight the effects of multiple sclerosis.
