Hmm, wonder if I need these?

I was looking through the medicine cabinet to try and find out when a prescription of Hannah's expires. I found three prescription information sheets from January of 2002! I wonder if I still need them? I really can't figure out where they came from because I have cleaned that cabinet out numerous times since then. The only thing I can figure is they were on the top shelf, which I don't really use, and someone moved them down or they fell down. Well, at least it was only the information sheets and not the actual medicine!
