The O2 User's Support Team is here to promote the use of oxygen as a first line cluster headache abortive and to provide information and answer questions on its proper usage.  The information provided in these pages come from scientific medical research and years of personal experience in the use of oxygen to stop the pain of CH.  

When used properly, 100% oxygen is effective for over 70% of sufferers and is less expensive and has fewer side effects than any other abortive medication on the market.  We recommend that all cluster headache sufferers talk to their healthcare providers about a prescription for medical O2.  We also invite you to share the resources provided here and discuss any recommendations we may give with your healthcare provider. 

You can submit questions or comments as they pertain to the use of medical O2 as a CH abortive by clicking on the Questions / Feedback link on the left or if you would rather contact us by e-mail, write to us at: o2help@ouch-us.org  Rest assured that we will never share your personal information with any outside person or organization. 

A Cluster Headache Sufferer’s Supplemental Guide To Aborting Cluster Headache Attacks With 100% O2 is available for download on the O2 Information page whose link is on the left.  We suggest you read through this document prior to submitting your questions as it addresses most of the common questions new and long-time users of medical O2 have generated over the years.
