Cluster headache is the most severe primary headache — intense unilateral pain with autonomic symptoms. Treatment includes high-flow oxygen (most effective acute), triptans, and preventive medications (verapamil, corticosteroids, lithium). Cluster headache requires specialist care for optimal management.
Acute treatment for cluster headache
High-flow oxygen: 100% oxygen at 12–15 L/min for 15–20 minutes — most effective acute treatment, ~70% respond. Triptans: sumatriptan injection or nasal spray — effective, fast-acting. Injectable sumatriptan: 6mg SC — rapid relief. Nasal spray: zolmitriptan, sumatriptan — faster than oral. Limit: triptans limited by MOH risk — use cautiously. Combination: oxygen + triptans — may be more effective. Avoid: oral triptans — too slow for cluster attacks.
Preventive treatment for cluster headache
Verapamil: calcium channel blocker — first-line preventive, requires monitoring (ECG, BP). Corticosteroids: short-term bridge — prednisone during transition. Lithium: mood stabilizer — effective for chronic cluster. Occipital nerve block: greater occipital nerve injection — aborts cluster. Galcanezumab: CGRP inhibitor — new, effective for episodic cluster. Topiramate: anticonvulsant — alternative preventive. Combination: may need multiple preventives — individualized.
Cluster period management
Episodic cluster: clusters last weeks to months — then remission. Chronic cluster: attacks >1 year without remission — more difficult. Transition: preventive treatment during cluster period — suppresses attacks. Tapering: gradual reduction of preventives — avoid rebound. Monitoring: regular follow-up — adjust treatment. Trigger avoidance: alcohol, nitroglycerin — can trigger attacks. Lifestyle: regular sleep, avoid alcohol — reduces triggers.
Cluster headache vs migraine
Severity: cluster is more severe — 'suicide headache' due to intensity. Duration: cluster is shorter — 15–180 minutes vs migraine 4–72 hours. Frequency: cluster is daily during cluster — vs migraine episodic. Autonomic symptoms: cluster has prominent autonomic — eye tearing, nasal congestion, ptosis. Restlessness: cluster patients are restless — vs migraine patients who prefer lying still. Treatment: cluster responds to oxygen — migraine does not. Misdiagnosis: cluster often misdiagnosed as migraine — specialist evaluation important.
When cluster headache needs specialist care
If you have severe unilateral headache with autonomic symptoms, suspected cluster headache, or cluster not responding to treatment — see a headache specialist immediately. Cluster headache requires specialist management.

Frequently asked questions
Answers reviewed by Dr. Jitendra Prasad Yadav • MBBS, MD (Internal Medicine), FICN (Neurology), FCNV, FIHM • NMC 8029
No; they are distinct disorders with different attack duration, features, and management.
Attacks occur in clusters — multiple attacks within a short time span, separated by pain-free periods lasting weeks to months.
Migraine is a neurological condition; headache is one feature. Associated symptoms and functional impact are important for diagnosis.
Aura refers to visual, sensory, or speech symptoms that precede the headache in some people. Both types are migraine; the presence of aura may influence management discussion.
Yes. Short or fragmented sleep impairs memory consolidation and lowers migraine threshold. Snoring with apneas fragments sleep and fragments cognition. Dr. Jitendra screens sleep duration, regularity, snoring and caffeine, and refers for sleep study when indicated — often before escalating headache or memory medicines.
