From someone (me) that treats many patients on an ambulance: PLEASE keep a current list in your wallet of 1: your name and birthdate (not all people carry their driver's licenses while adverturing), 2: your medications with dosages and how often, 3: your past medical history (hint: if you take medication for high blood pressure and it's now controlled, you still have high blood pressure), 4: allergies to medications and food, 5: someone to call in case you are unconscious (this person needs to know all about your medical history and have a list in front of them they can read to us AND preferably fax to the hospital we are taking you to). The list can be printed by the doctor. You don't have to hand write it (except for #5). If the list is changed by the doctor, ask for a print out before you leave the office. It is easy, just takes the click of a mouse. Makes life for the ambulance personnel so much easier. DON'T count on us to be able to find or work your cell phone. They are all different. Chances of your phone being lost or damaged are pretty good if you are unconscious. Paper is easier and quicker to use. If you are carrying medications that are NOT in the prescription bottle, that list from above is a must. One last thing, PLEASE take your medications as prescribed. You've asked the doctor to help keep you alive. Follow his/her advice or find another doctor whose opinion you like better.
