I can also vouch for the special band aid blister. They work extremely well.
I have a few emergency medical things I bring on every trip, but I also hit up pharmacies outside the US. I have a list of favorites and always make a point to hit City Pharma in Paris (I think it lives up to the hype!) and any pharmacy in Germany or Switzerland. Switzerland is the best (I love dropa but its only in certain regions). Russia was good too, I found my favorite throat medicine there and nasal spray and it was dirt cheap too.
