I'm looking to buy a health allergy bracelet that lists what im allergic too. Now i know I am allergic to Novocaine, procaine, lidocaine (xylocaine) but i don't know the name of that drug group. I looked on wikipedia and it says that procaine is a drug of the amino ester group. I want to really make sure before putting this on a bracelet that can save my life. Anyone know for sure?
