Hi everyone! I just wondered if anyone had any experiences to share of the washout period when swapping DMTs? Currently on tysabri with a high JCV so need to look at swapping to possibly ocrevus or kesimpta. Is there a period where I need to be aware of catching infections from others? How does the wash out period effect you? I have my tysabri every 8 weeks at the moment so how long would I have to wait between a last tysabri and a new drug? Thanks all
