A medical ID app has all your pertinent information in it, including any medical conditions you have. I have “in remission from pemphigus vulgaris,” along with my other conditions. You may want to state that you have one of the P/P rare diseases, or diabetes, or rheumatoid arthritis, or that you have a pacemaker. List your allergies and reactions, the name and phone number of your primary care physician or specialist, current medications, and an emergency contact. The app may also include your height and weight, which is important for medications given while in the care of a paramedic or the emergency room.
Even if you don’t have a medical condition, it’s always wise to have your medical information accessible “in case of emergency” (ICE). It’s a good idea to wear a medical alert bracelet or carry a medical ID with you, but since many people carry a cellphone at all times, it’s a great idea to use or install a health app. There may be a ♥ symbol as the health icon on your screen.
