Seishin, I have a medical alert "card" in my purse/wallet. It's more like a medical alert anthology.
The basics you should have on it are:
Name, date of birth, address, emergency contact name/numbers and health insurance coverage information.
You should have any drugs you are on, their doses and when they are taken.
I have the names and phone numbers of all of my doctors, including what their specialties are.
You should list your current conditions, any past surgeries and hospitalizations and any allergies or contraindicated drugs/foods. If you've had reactions to foods or drugs, list what they were (i.e., hives).
I have a very basic list of drugs and foods contraindicated in MG.
And, yes, I have a special little box that describes the basics about an MG crisis. I also have, "When in doubt, call my neurologist and pulmonologist."
The hospital closest to where I live has this information. I don't rely on that since it does change, so that's why I keep a copy with me.
While we're on the subject, if you guys don't have a health directive or wills in place, that's a good idea too.
