I have been researching oxymetazoline for some time now and have been using as a substitute for sumatriptan for nearly 3 years.
I am 100% certain that this aborts my cluster headaches.
Oxymetazoline as an α-adrenoceptor agonist, however it works as a full and potent agonist of serotonin receptor types 5-HT1A, 5-HT1B AND 5-HT1D, and is a partial agonist of 5-HT1C.
Sumatriptan works as an agonist of serotonin receptor types 5-HT1B and 5-HT1D.
It is believed that sumatriptan aborts cluster headaches because of cerebral vasoconstriction caused by its action as an agonist on serotonin receptor type 5-HT1D
So I firmly believe oxymetazoline aborts cluster headaches.
So far you are my first confirmation.
