My military type dog tag medical warning simply has epilepsy on the backside. It was originally on a chain around my neck, but as put on a key ring and clipped to my waist belt. Police and emergency personnel find it easy, with more information available in my wallet.

I have one.. It reads:
Penecillin
PDA '83
Craniotomy '03

Pda is an open heart surgery I had at 9 months old (important to know about if Im unable to communicate with medical professionals)
My neurologist suggested I put 'craniotomy' rather than the more accurate 'right temporal lobectomy' because he said 'everyone knows what the cranium is, not everyone will recognize lobectomy as a brain surgery... Once they see your scar they will be able to figure out what happened'

Its not glamorous but I have a custom designed gold,whitegold, and silver bracelet that I have only removed for MRIs and surgery for the past 18 years.

If you have metal implants (VNS) adding a line like this might help:

Embedded metal
Or
VNS implant

Hope this helps a bit.

I have “No ambulance unless injured” and my ICE info

I had some military style dog tags made. They have my name, that I have partial complex seizures, VNS, emergency contact, and to look for additional medical info in my wallet.

I wrote that I'm epileptic and my meds I'm allergic 2 cause those dont change and one is a Popular Seizure med and others are popular meds they give out.
