Damn. I didn’t realize. I have had it recommended by a doctor for mild sinus infections along with an anti inflammatory and it seemed to help, but I must admit I didn’t check any studies. I will say that the few I did find were about coughs, which could be different
I think Mucinex has been demonstrated to be as effective as phenylephrine (i.e., not).
Mucinex is recommended due to it having guaifenesin, it helps loosen up the mucus.
Phenylephrine is the stuff that doesn’t work, but it is usually found in Mucinex too.
Generic Guaifenesin syrup, ask the pharmacist. It’s OTC but sometimes it’s behind the counter
Phenylephrine isn’t the only OTC medication that doesn’t work.
