Interesting discussion! I have a small kitchen drawer in which I keep aspirin, ibuprofen, tylenol, allergy medicine, antacid tabs, alka seltzer, pepto bismol tabs, antibiotic ointment, cortisone ointment, and sunscreen, and a variety of bandaids. But I'm rethinking it based on the comments in this thread. I have to say it has been very popular and I've had positive comments on it, and the medicines are being used at a slow rate. I also have a store-bought first aid kit which is kept under the sink. I have a gadget which keeps the cabinets closed when children are present.
I know about aspirin allergy (also applies to pepto-bismol, which contains a similar substance), but I had assumed people with that allergy would know about it and stay away from the aspirin. But I may take those out. Food for thought! I'm not far from a pharmacy so no one should have to suffer for too long if they really needed something.
