Tysabri and the heart

Has anyone noticed any heart problems whilst on Tysabri? I started having episodes of heart palpitations/irregular heart beats after my 4th infusion but my doctor dismissed it, that it’s not a side effect of the infusion just a coincidence… has anyone had anything similar? Thank you!

Hey! Im about to start Tysabri, so I unfortunately don't have any input currently. Keep us updated! Ill check back in too if I get similar side effects.


Yes actually! Never thought of it though!
