Medical ID card for a parent: what to put on it

If your mom or dad collapses at the grocery store, the people helping them have a few minutes and no history. A medical ID card in the wallet, next to the insurance card, gives paramedics and the ER team the facts your parent may not be able to say. This guide covers what to write on it, what to leave off, and how to put the same information on their phone.

What a medical ID card is (and isn't)

A medical ID card (also called an emergency medical card, medical alert card or "in case of emergency" card) is a wallet-sized card with the health facts someone would need if your parent couldn't speak for themselves.

It is different from:

• A medical alert bracelet or necklace. Engraved, worn on the body, room for only a few words.
• A Vial of Life or File of Life form. A longer form kept on the fridge at home. See our Vial of Life guide.
• A full medication list. The complete list, with doses and prescribers, belongs on a separate page. See how to make a medication list for an elderly parent.

The card is the version that travels with your parent. Ready.gov's emergency advice for older adults lists exactly this kind of information: a list of medicines with dosage instructions and any allergies, "need-to-know information for first responders," and contact information for important people and care providers.

What to put on a medical ID card

Keep it to what a stranger needs in the first ten minutes. Here is the order that reads fastest:

1. Full name and date of birth. Exactly as on their insurance card, so the hospital can match records.
2. Critical conditions. Things that change what a responder does: heart conditions, diabetes, epilepsy, dementia, COPD, a pacemaker or other implanted device, recent stroke, kidney disease.
3. Allergies. Especially drug allergies (penicillin, sulfa, contrast dye) and serious food or latex allergies. Write "No known drug allergies" if that is true. A blank space is ambiguous.
4. Key medications. Blood thinners, insulin, seizure medications and heart medications first. If the full list does not fit, write: "Full medication list on the fridge and in the phone."
5. Emergency contacts. One or two people, with relationship and a mobile number. Pick people who will actually answer.
6. Primary doctor. Name and phone number.
7. Where the documents are. For example: "Healthcare proxy and POLST: in the blue folder, kitchen drawer" or "Copy with daughter Sarah." You don't need to attach them, just say where they are.
8. Language and communication needs if relevant: hearing aids, limited English, speaks Spanish.
9. Date updated. A card from three years ago may be worse than no card.

What to leave off

• Social Security number and full insurance member numbers. A lost wallet should not become identity theft. The insurance card is already in the wallet.
• Home address. It is usually on the driver's license already.
• Long medical history. Old surgeries that don't affect care today only slow the reader down.
• Anything you aren't sure about. A wrong dose is worse than "see full list."

A simple wallet card template

You can copy this layout onto an index card cut to wallet size (about 3.4 × 2.1 inches, a standard business card), or fold a half sheet of paper in quarters.

Front

• MEDICAL INFORMATION – Name: ______ DOB: ______
• Conditions: ______
• Allergies: ______
• Key medications: ______ (full list: ______)

Back

• In case of emergency call: ______ (relationship) ______ (mobile)
• Second contact: ______
• Doctor: ______ (phone) ______
• Documents (healthcare proxy / POLST): ______
• Updated: ______

Tips that make it last:

• Print or write in dark ink, no smaller than you can read without glasses.
• Laminate it, or put it in a plastic sleeve, so it survives the wallet.
• Make two: one in the wallet behind the ID, one in the car's glove box.
• Put a sticker or note on the front of the wallet: "Medical info inside."

If you want a full page for home as well, our free one-page ER sheet has room for the complete medication list, doctors and insurance, in US Letter and A4.

Put the same information on your parent's phone

Paramedics and ER staff often check a patient's phone. Both major phone systems can show medical information without the passcode:

• iPhone: in the Health app, set up Medical ID. It can include medications, allergies, conditions and emergency contacts. Turn on Show When Locked so it can be read from the lock screen, and Share During Emergency Call so it can be shared with emergency services where that is available (Apple Support).
• Android: in the Safety app (or Settings on some phones), open Your info to add medical information and emergency contacts. Anyone can view it from the lock screen by swiping up, tapping Emergency, then View emergency info (Google Android Help). Some steps need Android 12 or later.

Set it up together with your parent, on their phone, so they know it is there and agree to what it shows.

Keep it current

A medical ID card is only useful if it matches reality. Update it:

• After every hospital stay or ER visit. Discharge often changes medications.
• When a dose, medication or doctor changes.
• When an emergency contact changes phone number or moves away.
• On a regular check, for example every three months.

When you update the card, update the phone and the fridge copy the same day. Three versions that disagree cause more confusion than one.

How siblings can share one version

If several of you help, decide who owns the card and where the master copy lives. A shared document or a tool that keeps one current version means nobody prints a card from an old list. Whoever goes with your parent to the ER should also know what to bring to the ER.

ParentFile turns photos of the pill bottles, insurance cards and discharge papers into a one-page ER sheet, wallet cards and a medication list that siblings can open through a view-only link. You confirm every item before anything is printed. See what's in the ParentFile kit.
