I don't have that particular item in my medkit. But a huge medkit. Several, to be honest. One for the kid, one for travel, one (the biggest) at home in a cardboard box. And a good stash of all kinds of low-effect meds, and homeopathic stuff. I barely every use any, though.
And you're right. I should get my training updated. Last one was way too long ago.
