Different Box, Same Drug?

So, last night I figured I better get to the store and pick up some cold medicine to get some help getting over the sore throat and other suspicious symptoms I was suffering. In the past, I've found Tylenol Cold to be helpful, so I started looking for that in the medicine aisle at Wal-mart. Turns out there are now several varieties of Tylenol Cold. The first one I found was Tylenol Cold - Head Congestion, which seemed about like what I wanted, except that I didn't have much congestion, and I was actually sensing maybe a touch of fever.



After some more looking I found Tylenol Cold - Multi-Symptom, which listed Fever as one of the things it was good for.



But now that I was holding both boxes, I realized that both boxes listed the same active ingredients. I thought, "hmm...maybe there's a different ratio of ingredients between these two." Further inspection of the packaging revealed that, at least as far as I could tell, there was absolutely no difference between the two products. The amounts of each active ingredient, the warnings, everything. Is that weird or what?
