If you are congested, a nasal spray can be a useful tool to ease the stuffy feeling.
It’s a common occurrence, however.
Over-the-counter nasal sprays are only made to be used for three days, according toHealthline.

Using them for longer can lead to a condition called rhinitis medicamentosa, or rebound congestion.
This is simply congestion that is the result of medication rather than an irritant or virus.
Nasal sprays work by reducing inflammation of blood vessels that cause congestion.

This is not considered addiction, but rather dependence on the drug used in the nasal spray.
The only way to clear up the congestion is to stop using the nasal spray.
Flushing withsaline rinsehas been proven effective at clearing out blocked airways and is something you may want to try.
For congestion lasting longer, speak with your doctor about avenues of relief (viaHealthline).
