-Name
-Date of birth
-Name of primary physician (I didn't include this on mine, since I have not seen the same doctor consistently) and any specialists you see
-Allergies to medications
-Allergies to foods (especially eggs or shellfish)
-Allergies to anything else (latex, soaps or detergents, animals, etc)
-All the medications you currently take, or have taken recently. This includes any over-the-counter medications or herbal supplements you take at home, or home remedies you use
-Any medical conditions you have (diabetes, heart disease, thyroid problems, GI issues: anything the people treating you might want to know about)
-Significant family history - some people may debate the relevance of this item on a medical alert card; I just would like to give all the information I can to help emergency workers make informed decisions
-Contact information for your emergency contact
-Date the card was updated (I will add this to mine after this post)
Below is my current alert card; as you can see, it is nothing special (especially with information blacked out for internet use), but it would nevertheless be helpful in an emergency.
