Why were you put on Plavix in the beginning... for heart attack or stroke
? Absolutely going off of it can lead to a mini
/TIA, but going odd wont CAUSE one. Unfortunately you have to go off before a biopsy as it makes your blood thinner and there is too much risk of bleeding. Don't worry too much about the TIA, most have no long standing effects unless you have a LOT of them. So you want to go back on the Plavix and DON'T miss any doses! It should work right away.
