I just want to reiterate this. Many, many older teens and young adults have no idea how to take care of themselves when they get sick. They don't know one OTC medication from another or when to take an illness or injury seriously. Most of them do not know the generic names for medications, so if you give them a
Walmart brand of tylenol, be sure you label it "same as tylenol."
My oldest left home at 18 for a tour with Disney On Ice. He was just clueless. So I made up a special first aid kit in a shoe box for him. Included were the usuals: bandaids, neosporin, thermometer, benedryl, Motrin, cough drops. I also made him a card file on an O-ring. Three 4"x6" cards.
**First card had all his emergency numbers on it, allergies, doctors' names & numbers, and routine medications. Also, a copy of the front and back of his insurance card. Instuctions in large letters "TAKE THIS TO THE HOSPITAL WITH YOU"
**Second card was "What to do if you get sick".
Vomiting--small sips of gatorade every 15 min.
Diarrhea--drink extra fluids, no milk or juice. Eat what you like.
Headache--take 2 motrin every 6 hours. Do not take more than 2 at a time(I had to spell it all out for him.)
I also hit cough, cold, rash, cuts and sprains.
**Third card was "When to go to the doctor or ER" .
Vomiting green stuff or more than 8 times in 8 hours--go to ER
Bleeding that you can't stop easily with pressure--go to ER.
Fever with sore throat or chest pain--go to doctor
Fever over 101 more than 24 hours--go to doctor
Head injury that knocks you out--go to ER(call 911)
Hard to breathe or painful breathing--go to ER or call 911
And other stuff that escapes me at the moment.
I put this card file in the first aid kit, on top. I instructed him to consult with the cards for instructions FIRST, but he could call me if he had questions. Well, one day he got really sick in Portland, Maine. Vomiting his head off for about 5hours, really miserable. He called and I told him what to do. 30 minutes later he called back, he feels much worse. I told him to ask the hotel clerk to help him find a doctor or hospital. 30 minutes later I get a call from the EMERGENCY ROOM!

Its the ER doc--he passed out in his room and they had to call 911! OMG! And I'm in Atlanta, over 1000 miles away!
Well, the ER doc said he was severely dehydrated and was getting some IV fluids, but she was most impressed with his card file--he somehow remembered to take it with him.

She said he had followed his directions to the letter, just didn't go to the hospital as soon as he should have(he was trying to make it to work.) She kept him there for about 8 hours, then let him go back to the hotel to finish sleeping off the illness.
DD16 will be going off to college in a little over a year and I plan to make something similar for her. It's certainly okay for my kids to call me when they're sick, but it really makes them feel adult-like when they can figure it out on their own.
