Need Medical Oxygen for Cluster Headaches?
Breathing pure oxygen through a non-rebreather mask at 12–15+ liters per minute can stop a cluster headache in under 15 minutes. Use our free directory to find local oxygen suppliers, high-flow regulators, and prescription tips.

Because cluster attacks hit full strength within minutes, treating them usually takes a two-part approach: stopping the pain right away, and preventing the next attack from starting.
Stopping an Attack (Fast Relief)
The two fastest, most proven ways to stop an attack are breathing 100% pure oxygen at high flow rates (12–15+ L/min) and using injectable sumatriptan (Imitrex). While oxygen is highly effective and safe, some patients report that sumatriptan causes rebound headaches.
Preventing Attacks (Daily Meds)
Daily medications are used to keep attacks from starting during a cycle. The most common daily drug is verapamil (a blood pressure pill). Doctors also use short courses of steroids, nerve blocks, or newer monthly shots like Emgality to calm down active cycles.
Alternative & Emerging Options
When standard medications don’t work, patients and researchers look into nerve stimulators (like gammaCore), non-traditional therapies, and clinical trials exploring psilocybin (mushrooms) to break stubborn cycles.
What is a Cluster Headache?
A cluster headache is a neurological condition that causes excruciating, sharp, or burning pain on one side of the head almost always centered right behind or around one eye or temple.
It is entirely different from a typical headache or migraine. Attacks arrive without warning, peak within minutes, and generally last between 15 minutes and 3 hours. They strike in clusters occurring anywhere from once every other day up to eight times in a single 24-hour window, often waking people up at the exact same hour every night.
During an attack, the eye on the painful side often becomes red, bloodshot, and tears up, the eyelid may droop, and the nostril commonly congests or runs. Because the pain is ranked among the most severe known to medical science, patients rarely lie down; most pace, rock, or stay in constant motion until the episode subsides.
