Engrave your medical ID with any allergies that may cause a medical emergency, such as ALGYS: BEES & PEANUTS. People often also engrave instructions to call 911 and give epinephrine, as this information is helpful for bystanders and good samaritans to have before emergency personnel arrives. It is also a good idea to engrave allergies that impact your treatment, for example: ALGYS: LATEX & MORPHINE.
