Oxygen therapy for headache is, first, high-flow normobaric oxygen: 100% oxygen through a non-rebreather mask for fifteen to twenty minutes. It is a first-line abortive for cluster headache. It does not treat migraine. Hyperbaric oxygen is a separate treatment with limited evidence.
We offer two different oxygen treatments. They are not interchangeable. The evidence behind them is not comparable. And they are used for different things.
Does high-flow oxygen stop a cluster headache?
Strong evidence
One hundred percent oxygen, delivered at high flow through a non-rebreather mask. You breathe it for fifteen to twenty minutes at the onset of an attack. “Normobaric” simply means at ordinary room pressure — you sit in a chair and breathe through a mask.
This is a first-line abortive treatment for cluster headache. It is one of the genuinely unusual treatments in headache medicine. It is highly effective for the right patient. And it has essentially no systemic (whole-body) side effects, no interactions and no ceiling on how often it can be used. A randomized controlled trial published in JAMA in 2009 established that high-flow oxygen aborts cluster attacks substantially more often than air within fifteen minutes. It has been a guideline-recommended treatment since.
It has to be actual high-flow oxygen through a non-rebreather. A nasal cannula at a few liters per minute does not reproduce the effect. That is the single most common reason someone tells us “oxygen didn’t work for me.”
It does not treat migraine. If your diagnosis is migraine, this is not the treatment for you and we will say so.
Does hyperbaric oxygen (HBOT) help headaches?
Limited evidence
Hyperbaric oxygen is different in kind, not just in degree. You are enclosed in a chamber, and the pressure around you is raised above atmospheric pressure. That dissolves considerably more oxygen into the blood than breathing oxygen at room pressure can.
We will be straight about where this stands. Systematic reviews of hyperbaric oxygen for headache have found some evidence that it can relieve an acute migraine attack. But the trials are small, older, and of low methodological quality. Reviewers have consistently declined to recommend it as routine acute treatment. There is no good evidence that it prevents future attacks. There is also no good evidence supporting it for cluster headache. In cluster headache, normobaric oxygen already works well and costs a fraction as much in time and money.
That is not a reason it is never appropriate. It is a reason it should not be anyone’s first option for a headache. It is also a reason we will talk you out of it if a better-supported treatment has not been tried. Maybe you have been offered hyperbaric oxygen for migraine somewhere that did not tell you the evidence is thin. If so, that is worth knowing.
Which oxygen treatment do you need?
If you have cluster headache, you want high-flow normobaric oxygen. You likely also want a home setup, so you can use it at the first sign of an attack rather than driving somewhere. We can start it here and arrange the prescription.

A note on coverage, and on timing. Same-day treatment and prior authorization do not run on the same clock. Many insurers take days to weeks to decide, and some acute headache treatments are not covered at all. Your headache will not wait for that process.
We will verify your benefits and, where a treatment needs prior authorization, we will attempt to obtain it. An authorization confirms that a service meets criteria for review — it is not a guarantee of payment, and no clinic can make that promise on your insurer’s behalf. Where something is unlikely to be covered, or cannot be certified in time to treat you today, we will tell you before we treat rather than after, so the decision is yours. Payment is due at the time of service.
Frequently asked questions
How long do you breathe oxygen for a cluster headache?
Fifteen to twenty minutes, started at the onset of the attack. The oxygen is 100%, delivered at high flow through a non-rebreather mask. You sit in a chair and breathe at ordinary room pressure. It has essentially no systemic side effects and no interactions. Because of that, there is no ceiling on how often you can use it.
How do you get oxygen at home for cluster headaches?
We can start high-flow oxygen here and arrange the prescription for a home setup. That matters because an abortive treatment works best at the first sign of an attack, not after a drive to a clinic. The home setup has to be the right equipment: high-flow oxygen with a non-rebreather mask, not a low-flow nasal cannula.
Why didn’t oxygen work for my cluster headache?
The most common reason is the delivery, not the oxygen. A nasal cannula at a few liters per minute does not reproduce the effect. It has to be 100% oxygen at high flow through a non-rebreather mask, breathed for fifteen to twenty minutes at the onset of the attack. If you were never given that setup, oxygen has not really been tried.
Does oxygen therapy help migraine?
High-flow normobaric oxygen does not treat migraine. It is a treatment for cluster headache, and if your diagnosis is migraine we will say so. Hyperbaric oxygen is breathed inside a pressurized chamber. It has limited evidence for relieving an acute migraine attack. It has no good evidence for preventing future attacks. So it should not be anyone’s first option.
