Hah, no actually, I’m half-joking here. I did get hives and bleeding from amoxicillin/clavulanate and my mother has had the same, so it’s probable, but I would definitely want to double-check anything I put on me!

The “If Dead” bit is tongue-in-cheek because it’s probably legally useless, although I guess something like that could function as a way to get in contact with the right people in the event of an emergency, whether for cryo or notifying kin.
