Explanation

Nasal decongestants are helpful for short-term relief from stuffy noses, but using them for too long can cause issues. Rebound Congestion: If you use nasal sprays for more than 3-5 days, your nose might become more congested when you stop. This is called rebound congestion or rhinitis medicamentosa.

Why Limit Use?: According to the studies, extended use of nasal decongestants can lead to a cycle where your nose becomes dependent on the spray to stay clear. This means you might need to use it more often, which can make things worse.

What to Do: If your nose is still stuffy after a few days, it might be better to talk to a doctor. They can help find another solution that won’t cause these problems. Remember, it's important to follow the instructions on the medicine label and not use it longer than suggested.
