My Step-Mother has started using Avonex in the past three months or so. In the last week she has started shouting and screaming at me, completely unprovoked. She also repeats things that are not true and seem very warped. (e.g. shouting "I'm a drug dealer" - I certainly know that she isn't!) Despite being very upset about the situation myself, I thought it best to first find out if these injections could be the cause, before I try to tackle it in another way.

I appreciate any answers as I unfortunately know nothing about this drug besides what she has told me.
