Oxygen is recommended for the treatment of acute cluster headache attacks. However, it is not available worldwide.
Methods
The International Headache Society performed a survey among its national member societies on the availability and the restrictions for oxygen in the treatment of cluster headache.
Results
Oxygen is reimbursed in 50% of all countries responding (n = 22). There are additional restrictions in the reimbursement of the facial mask and with respect to age.
Conclusion
Oxygen for the treatment of cluster headache attack is not reimbursed worldwide. Headache societies should pressure national/public health authorities to reimburse oxygen for cluster headache in all countries.
