I only carry aspirin, Immodium, Benadryl, Ibuprophen, and Pepcid AC in my WSK. I repacked them all together in a waterproof vial with a label describing what they are by color. Evidently studies have been conducted which show that the shelf life of prescription and OTC meds are sometimes grossly underestimated by the manufacturer (I wonder why? <img src="/images/graemlins/grin.gif" alt="" />) Mention of these studies are made here:

In short, assuming my OTC meds are kept clean and dry, I'm not going to worry too much about expiration dates from now on. I'll probably check them every year and replace them every 3 years or so. Of course, if I had to carry any prescription meds I might be a bit more vigilant than that.
