I used Avonex for 10 years and have been on Tysabri for 16 months. I developed some retinal infarcts 2 weeks ago and had blood tests which show I am anemic. I have been stable and have had no adverse effects until now. My neurologist stopped the Tysabri until we can determine the cause for the anemia.
Today was the first day I have had any symptoms...wiped out all day and my wife says I look pale. As if MS doesn't cause enough fatigue
Has anyone else had any similar stories?
