Brands like Sudafed®️ have these nasal sprays that just provide an immediate relief from nasal decongestion & was wondering what makes it so effective and why manufacturers only recommend using it for up to 3 days.
In: Chemistry
Nasal decongestants work by shrinking blood vessels, so the tissues immediately shrink. But if you use them for too long, your body will get used to them and need more and more to get the same effect… the tissues get really swollen and inflamed, and you might need strong steroids to be able to counteract it. So follow doctor’s orders and only use for 3 days at a time!
Nasal steroid sprays like Flonase, on the other hand, work best when used for long periods of time. So start using Flonase a month before allergy season and use it daily for best results.
