I'm sensitive the the urushiol oil in poison ivy, typically suffer with outbreaks 6-8 times each year. That's a lot less than it used to be. I've been through many incidences with my eyes swollen shut and 1"+ diameter blisters all over face and arms. Prednisone was always the prescription that cleared it right up, I never messed with the anti-itch dopes and such. These days I wash down any exposed skin with rubbing alcohol after being out in the woods, every time. I still get it fairly often but the rubbing alcohol really cuts down on the severity, it works me.

I use glyphosate to kill it, I spray it as many times as necessary. Any brush with it on or in goes to a brush pile and burned, I just stay upwind. Good luck.
