I've certainly found it useless, and when I need a decongestant I make certain I'm getting actual pseudoephedrine. The 12 and 24 hour slow-release versions are fantastic. I've never done a proper blind trial on myself, but I feel quite certain that I could tell the difference.

I suppose people must be buying it, and given how strong placebo effects are in general I guess it's doing something for them.

Same here. Actual Sudafed works for me and anything else I think generally only tends to work with whatever NSAID they bundle with it.

The Wikipedia article they link to [0] has a pretty long list of brandnames. Many of them are the "-D" version of whatever the thing is. Claritin-D, Zyrtec-D and so on. I think the version without the "-D" doesn't have Pseudoephedrine?

My assumption has always been: people know pseudoephedrine works, so that's what they want to buy, but you can no longer sell pseudoephedrine over the counter. However, you can offer phenylephrine, which still lets you reasonably name the drug "Sudafed PE" or whatever. Customer browses the shelves, sees "PE" in the drug name, this triggers a vague impression that it contains pseudoephedrine and thus will actually work well.
