@Kat919 - I actually got tricked by that! I bought a medicine that I had bought before and it didn't work as well for me because they had changed out the decongestant. Now I know to go the counter.
But apparently phenylephrine vs pseudophedrine is a personal choice. My sister really likes the new formulations because pseudophedrine makes her feel kind of wired, while the phenylephrine does not.
