Pretty basic...

5, 1" x 3" Bandaids
2 butterfly closure bandages
1, 2" x 2" sterile gauze pad
5 antiseptic wipes
2 packets of antibiotic ointment
2 pieces of moleskin
1 sting relief wipe
1 small roll of medical tape
1 pair of tweezers

OTC meds: 1, single-dose packet each of Bayer aspirin (for heart attack, not pain), Immodium, antihistimine/decongestant, Pepto Bismol tablets.
3, single-dose packets of Advil.

I've never had to use anything other than the moleskin, Advil and Pepto.
