Is that the stuff that you can have withdrawal from? I remember after using a nasal spray when sick, if I used it too much for a week, the next two weeks id get really clogged up.
What you're talking about is oxymetazoline and its analogs, like in Afrin nasal spray.
Oxymetazoline is super potent and works immediately on nasal passages, but it can be risky to stay on for more than a few days straight.
Steroids like fluticasone don't work immediately, and take a couple of days to kick in, but you can use them indefinitely. Also, in addition to opening nasal passages, they have general anti-allergic effects -- i.e. they can help with itchy, watery eyes and facial swelling.
