Over here in Germany, when you ask for a decongestant, you usually get Xylometazolin as a spray. As I understand, that's both more effective and has fewer side effects (due to being local). You can also get pseudoephedrine, but I don't think it's as commonly used as these nasal sprays.
> As of 2021, no consumer products containing xylometazoline are marketed in the United States, however imported products containing xylometazoline are available online.
From the wikipedia article. Fascinating, it's the most common drug I use and it's not even available in US stores!
Is that not an option in the US?
