isopropyl alcohol
Treatment for Cluster Headache
Isopropyl alcohol, when inhaled nasally during a cluster headache attack, acts rapidly to constrict cerebral blood vessels and modulate neural pain pathways, potentially interrupting the trigeminal-autonomic reflex. Its quick absorption through the nasal mucosa allows for fast-acting vasoconstrictive and analgesic effects, which can provide acute symptomatic relief during cluster headache episodes.
