I use a kitchen cabinet with three shelves. The first shelf holds medicine; the second shelf holds paper plates, plastic cups, sandwich bags, freezer bags, etc.; the third shelf holds small board games.
DH attached two "spice racks" inside the cabinet door on the medicine shelf. These hold 8-10 bottles/boxes of meds. On the first rack, I keep all the prescription meds we use daily. The second rack holds seasonal meds. Inside the cabinet I use a shelf stacker and little baskets to store thermometers, thermometer covers, medicine cups/droppers, band-aids, first-aid creams, etc. In front, within easy reach, are pain relievers, cough syrups, etc. We also keep insect repellent, sunscreens, etc.
I really like this cabinet---it is probably the most organized place in my whole house!
