medic alert bracelets are the way to go. as ex law enforcement & emt i recommend them..as an asthmatic, did etc i had one...they are standard, recognized, do have the 24 hr phone back up etc.

one that is home made is nice but it is just that...in an emergency it is still your word..& a home made card is like a bank robber saying it is ok for me to take this $$ because i need it...the card won't carry much weight.

medic alert items..the necklace, bracelet, etc are items that personnel are trained to look for when assessing people as they arrive to provide care. they list conditions right on them & provide a phone # for their services. once called they give access to anyone you want as far as family, friends, dr's t, etc. you list your meds...everything...

doesn't cost that much for an annual fee & it is so much worth it for peace of mind.

you can pretty much list anything on the form & send it in (or on line now i imagine) but it is what i would go for..i don't have one now but i do carry a list of all my meds, contacts, etc in my wallet for when i do need it (too many to remember)..but if i was as ill as i used to be..medic alert would be slapped on my wrist.

(i don't work there, or have any affiliation with them..just saying it made life so much easier when responding to an emergency...for everyone)
