Oxymetazoline is a decongestant that works by narrowing blood vessels in the nasal lining [2]. This mechanism differs from other types of nasal sprays, such as saline sprays, which moisturize the nasal passages, or corticosteroid sprays, which reduce inflammation over time and are used for conditions like allergies [3]. Unlike saline or corticosteroid sprays, oxymetazoline should not be used for more than three consecutive days to avoid rebound congestion [2].

Yes, prolonged or excessive use of oxymetazoline hydrochloride nasal solution can lead to rebound congestion, also known as rhinitis medicamentosa [2]. This occurs when the nasal tissues become dependent on the medication, and congestion worsens when the drug wears off [2]. To prevent this, it is generally recommended to use oxymetazoline for no more than three consecutive days [2].
