What approach do you take to updating your first aid kit? I checked my kits, and all the small packets of over-the-counter meds have expired. There are also some items that have no expiration date, which makes me suspicious. The antibiotic cream doesn't have an expiration date? That doesn't seem right?

Also, I keep a kit in my car, and it gets really hot in there in the summer. I'd think meds have a shorter life.

Buying individually packaged pills is pricey for what you get. I wonder whether it might not be better just to buy a new kit. So do you "refill" your kit, or do you just, at some point, settle for a new one?
