Detailed Description:
This multi-center, adaptively randomized, double-blind, placebo-controlled trial will evaluate the efficacy and safety of a nasal, non-inhaled administration of carbon dioxide (CO2) in the treatment of mild headaches. An estimated 250 patients who meet the eligibility criteria will be enrolled into this study at approximately 15 sites to ensure that about 220 patients are randomized and complete the study.
Eligibility| Ages Eligible for Study: | 18 Years to 65 Years (Adult) |
| Sexes Eligible for Study: | All |
| Accepts Healthy Volunteers: | No |

- History of 2-8 migraine attacks per month during the 3 months prior to randomization
- Have a typical migraine which progresses from a distinct mild headache to a moderate or severe migraine
- Able to recognize a mild headache that could develop into a moderate or severe migraine
