I got my husband a bracelet from Medic Alert Foundation https://www.medicalert.org/ after his kidney transplant. Being able to have an account with them, we can load in his drs, his medications, etc., that is all accessible by first responders calling the 800 number and getting information. I have the same set-up, useful in an emergency.

Another thing that I have done, is that I carry a current list of medications he is on, in my wallet, and he does the same for me both OTC and Rx]. Decades ago, my mother had a mini-stroke while out of town, and had combined all her medications in to one bottle. When we got her to the ER, it was havoc to determine what she was taking, and speak clearly to attending doctors.
