My anecdata is that, though it's not as effective as pseudoephedrine, phenylephrine actually is effective in an inhaler, and a helluva lot better at clearing up a stuffy nose than "scents and essential oils". Of course, a cylindrical inhaler with a wick inside it doesn't go near my digestive tract... Now I'll have to look around for a replacement inhaler, something quick enough to avert choking-panic. Thanks, CVS.
