Cluster headache is treated in three layers: fast acting acute treatment, usually high-flow oxygen or injectable sumatriptan; a short transitional course to break the bout quickly; and a preventive taken through the bout, most commonly verapamil. Because attacks reach full severity within minutes, oral tablets are usually too slow and acute treatment must be physically within reach including overnight.
Cluster headache is treated in three layers: fast acting acute treatment, usually high-flow oxygen or injectable sumatriptan; a short transitional course to break the bout quickly; and a preventive taken through the bout, most commonly verapamil. Because attacks reach full severity within minutes, oral tablets are usually too slow and acute treatment must be physically within reach including overnight.
Attacks reach full severity within minutes, so oral tablets are usually too slow to help. High-flow oxygen through a suitable mask aborts attacks for many people and has no systemic side effects, which makes it particularly valuable; arranging home oxygen requires a prescription and equipment, so raise it early. Injectable or nasal sumatriptan works faster than tablets. Whichever is used, it needs to be physically within reach including overnight, since attacks frequently wake people.
Because preventives take time to become effective, a short transitional course is often used to suppress attacks in the meantime; a tapering course of corticosteroids or an occipital nerve block are both used for this, and blocks are available within this practice. Verapamil is the most widely used preventive and requires ECG monitoring because it affects cardiac conduction. Other options include lithium and certain anti-seizure medications, and a CGRP-targeted antibody is approved for episodic cluster headache.
Most people have bouts lasting weeks to months with remission in between, so preventive treatment is typically started at the beginning of a bout and tapered once it ends rather than taken indefinitely. That makes recognising your own bout onset genuinely useful, because starting early shortens the period of uncontrolled attacks. Do not stop verapamil abruptly, and tell any clinician prescribing for you that you are taking it, since interactions matter.
