Claritin D has the ephedrine in it.
That’s likely what has to be reported for being sold.
that would certainly do it. I prefer my decongestants on the side, that way I can adjust dosages more easily. Generally, none at all...
I've always had bad results with taking more than one or two doses of decongestant. I get a really bad rebound effect, usually by the 3rd or 4th dose. May be because I used to use them very heavily.
