afrin
Treatment for Cluster Headache
Afrin (oxymetazoline), a sympathomimetic alpha-adrenergic agonist, causes vasoconstriction of nasal and perinasal blood vessels, which can provide rapid relief in cluster headaches by reducing inflammation and congestion. Its direct vasoconstrictive action helps to alleviate the intense pain and autonomic symptoms associated with cluster headache episodes by modulating regional blood flow and reducing vascular dilation.
