Brief summary: This study will evaluate the effectiveness of Treximet when taken for post traumatic headache by measuring any change in the number of headache days or any change in a subject's ability to think following treatment with study medication. Eligible subjects will complete 3 visits. Following Visit 1, subjects will treat with their usual medication and document headache symptoms and therapy in a Headache Diary. After 30 days, subjects will return for Visit 2 and be randomized (like the flip of a coin) to receive Treximet or matching placebo to treat at the same time each day. Treximet will be provided to treat any headache that occurs. Subjects will complete a daily Diary. After 30 days, subjects will exit the study at Visit 3.

Detailed description: Subjects will be enrolled at 3 investigative sites. At Visit 1, a medical, headache, and medication history will be collected and a physical and neurological exam with vital signs will be performed. An ECG will be completed if one has not been completed in the previous 6 months. Subjects will be administered a series of psychological tests to help the study doctor decide whether or not a subject is eligible. The Headache Impact Test-6 and Migraine Specific Quality of Life Questionnaire will be completed at each visit. During a 30-day Baseline Period, subjects will treat with their usual medication and complete a daily Diary documenting headache symptoms and treatment. At Visits 2 and 3 subjects will complete the Mental Efficiency Workload Test and Migraine Early Warning Tool. Following randomization at Visit 2, subjects will treat daily for 30 days with Treximet or a matching placebo. Subjects will be provided with Treximet for rescue of any persisting or recurring headache. During the Treatment Period, subjects will complete a daily Diary reporting headache symptoms and response to treatment. After the 30-day Treatment Period, subjects will exit the study at Visit 3 .

Eligibility criteria: Inclusion Criteria:

Subject

* is male or female between the ages of 18-65. A female is eligible to enter and participate in this study if she is of: a.non-childbearing potential (i.e., physiologically incapable of becoming pregnant); or,b. child-bearing potential, has a negative pregnancy test (urine or serum) at Visit 2, and agrees to one of the following: Complete abstinence from intercourse from 2 weeks prior to administration of the investigational product, throughout the study, and for a time interval (5 days) after completion or premature discontinuation from the study to account for elimination of the investigational drug; subjects utilizing this method must agree to use an alternate method of contraception if they should become sexually active and will be queried on whether they have been abstinent when they present to the clinic for the final visit or, Female sterilization; or, Sterilization of male partner; or, Implants of levonorgestrel; or, Injectable progestogen; or, Oral contraceptive (combined or progestogen only); or, Any intrauterine device (IUD) with published data showing that the highest expected failure rate is less than 1% per year (not all IUDs meet this criterion); or, Spermicide plus a mechanical barrier (e.g., spermicide plus a male condom or a female diaphragm); or, Any other barrier methods (only if used in combination with any of the above acceptable methods); or, Any other methods with published data showing that the highest expected failure rate for that method is less than 1% per year.

* has blood pressure ≥140/90 millimeters of mercury (mmHg) in 2 out of 3 BP measurements at screening or is taking any angiotensin-converting enzyme (ACE) inhibitor or angiotensin receptor blocker
* has a history of significant congenital heart disease, cardiac arrhythmias requiring medication, or a history of a clinically significant electrocardiogram abnormality that, in the investigator's opinion, contraindicates participation in this study
* has evidence or history of any ischemic vascular diseases including: ischemic heart disease, ischemic abdominal syndromes, peripheral vascular disease or Raynaud's Syndrome, or signs/symptoms consistent with any of the above

* has a recent history of regular use of opioids or barbiturates for treatment of their migraine headache and/or other non-migraine pain or any medication overuse that in the opinion of the investigator has exacerbated or contributed to the current headache pattern of the subject.
