This page is inaccurate 

It actually said that prior to 2002, the cough and cold variety of coro contained pseudoephedrine rather than chlorpheniramine maleate? wtf? seriously, that is terrible. I remember even way back in like 1999, when i used to pop the skittles it had chlorpheniramine. i removed that. there are a whole lot of other things on this page that need sources/references.
