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
I believe they’re basically steroids for the glands in your nose, forcing the nasal walls to contract shortly after contact.
As to why it’s bad to use them for longer than 3 days, your nose will develop rebound congestion, which is worse than the congestion that was treated initially and very uncomfortable.
