Hi guys hope everyone is keeping safe in this new world order we are going through! I am writing this post as I have rrms and have been receiving natalizumab ( tysabri ) at monthly treatments for last 9 years and I am switching to every 6 weeks instead of 4. Can anyone out there describe in any way what that change will be like? I resisted for a while as I'm a "ain't broke, dont fix it" kinda person but due to pml risks and the current health crisis I have changed my treatment plan and was hoping anyone could give some tips on what to expect? Keep safe and remember rule 32 of the zombie apocalypse!
