Hi all - in April I agreed with my neurologist to switch from tecfidera to tysabri due to increased activity in my MRI. I’ve done the various tests that need to be done before starting Tysabri, but am still waiting for confirmation of when I’ll start, I’m conscious that I’ve been told I’ll have a month’s wash out period after stopping Tec, so realistically am not looking at starting for a while yet, but the lack of clarity from my MS team at UCLH is getting a bit frustrating. Does anyone have any experience for how long it’s taken to switch treatments? Am I just being an annoying patient? Thanks! Alice
