Can you become addicted to nasal decongestant sprays?

Yes, you can develop a dependency on nasal decongestant sprays if you use them for longer than seven days. When you overuse these sprays, your nose becomes caught in a cycle where stopping the spray causes worse congestion than before, leading you to use it more frequently. This condition, called rebound congestion or rhinitis medicamentosa, involves both physical changes in your nasal passages and psychological reliance on the spray.

Key points:

Only decongestant sprays containing xylometazoline or oxymetazoline cause this dependency; steroid sprays and salt water sprays do not
The dependency develops because the spray initially clears congestion but then triggers increased congestion when you stop using it, trapping you in a cycle of repeated use
Using the spray for more than a week significantly increases your risk, with an estimated 5.5 million people in the UK having used these sprays long enough to risk dependency
Sleep problems, anxiety, and loss of smell are common experiences reported by people dependent on nasal decongestant sprays
