Were you looking for information about Avonex? Avinex is a common misspelling of Avonex.
Avonex® is a multiple sclerosis medication available by prescription. It is thought that the drug works by preventing the immune system from attacking and destroying the protective coating around nerve fibers. Since Avonex would be digested and inactivated by the digestive system if taken by mouth, it must be injected into a muscle once weekly. Potential side effects of Avonex include headache, weakness, and fever.
