Xylometazoline, also spelled xylomethazoline, is a medication used to reduce symptoms of nasal congestion, allergic rhinitis, and sinusitis.[2] Use is not recommended for more than seven days.[3] Use is also not recommended in those less than three months of age and some say not less than 6 years of age.[3][4] It is used directly in the nose as a spray or drops.[3]

Side effects include trouble sleeping, irritation of the nose, nausea, nosebleed (3%), period pain (10%) and headache (3%).[5][2][3] Long term use (> 10 days) is not recommended due to a rhinitis medicamentosa when stopped.[5][6] Use is not recommended during pregnancy.[2] Xylometazoline is in the decongestant and alpha-adrenergic agonist families of medication.[6][7]

One study classified it with selectivity ratios in alpha 2 adrenergic receptors of 151 for a2A vs a2B, 4.5 a2A vs a2C, and 33.9 a2B vs a2C.  Making it a highly selective a2A agonist.[8]

Xylometazoline was patented in 1956 and came into medical use in 1959.[9][10] It is on the World Health Organization's List of Essential Medicines.[4][11] Xylometazoline is available as a generic medication.[3]
