3. Migraine-associated nausea with ≥half of migraine attacks.
4. 5-8 migraine/probable migraine headache days on average per month in the three months prior to Visit 1 and during the Baseline Period.
5. The patient agrees to refrain from taking opiate medications from Visit 1 to 7 days after the last dose of the study drug.
6. The patient is able to complete study questionnaires, comply with the study requirements and restrictions, and willing to provide written informed consent and authorize HIPAA.
7. The patient has been taking a stable dose of a medication with migraine prevention potential for at least 3 month prior to the screening visit and agrees to not start, stop, or change dosage of any medication with migraine prevention potential during the study period. (E.g., beta-blockers, calcium channel blockers, tricyclic antidepressants, anticonvulsants, selective serotonin re-uptake inhibitors (SSRIs), serotonin-norepinephrine re-uptake inhibitors (SNRIs), magnesium or riboflavin supplements at high doses, herbal preparations (e.g. feverfew or St. john's wort)), Botulinum toxin must be discontinued one year prior to Visit 1.
8. The patient agrees to forgo any elective surgery for the duration of the study.
9. The female patient who is premenopausal or postmenopausal less than 1 year, or have not had surgical sterilization (i.e., tubal ligation, partial or complete hysterectomy) must have a negative urine pregnancy test, be non-lactating, and commit to using 2 methods of adequate and reliable contraception throughout the study and for 28 days after taking the last dose of the study drug (e.g., barrier with additional spermicidal, intra-uterine device, hormonal contraception). Male patients must be surgically sterile or commit to the use of 2 different methods of birth control during the study and for 28 days after the study.

Exclusion Criteria:

1. Usage of acetaminophen and non-steroidal anti-inflammatory drugs (NSAIDs) ≥15 days/month, or ergotamine and triptans \>10 days/month, or opioids and barbiturates \>2 days/month in the 3 months prior to Visit 1 or during the Baseline Period.
2. Tension-type-like, and/or migraine-like headache on ≥15 days per month in the 3 months prior to Visit 1 or during the Baseline Period. Diagnosis of chronic migraine, cluster headache or neurologically complicated migraine (hemiplegic, basilar, retinal, ophthalmoplegic migraine).
3. Regular use of the following medications for any reason: acetaminophen, non-steroidal anti-inflammatory drugs (NSAIDs), antipsychotic drugs, monoamine oxidase inhibitors, benzodiazepines, sleep medications, muscle relaxants, anti-emetic medications, blood thinning medications (e.g., warfarin or heparin), cannabinoids, or botulinum toxin to head and neck regions. Low-dose aspirin for cardiovascular disease prophylaxis is permitted.
4. Confounding painful conditions, (e.g. fibromyalgia, chronic low back pain, complex regional pain syndrome, etc.).
5. Diagnosis of any concurrent medical or psychiatric condition; this includes, chronic unstable debilitating diseases such as Parkinson's disease, multiple sclerosis, cancer, significant renal impairment, significant hepatic impairment, etc.
6. The patient has a history or diagnosis of moderate-to-severe hepatic or renal impairment (\>2 × the upper limit of normal \[ULN\] for alanine transaminase or aspartate transaminase. ≥1.5 × ULN for alkaline Phosphatase, bilirubin, BUN, or creatinine). (Patients with elevated bilirubin level due to Gilbert's syndrome are allowed).
7. The patient has a history within the previous 5 years of abuse of any drug, prescription, illicit, or alcohol.
8. The Female patient is pregnant, actively trying to become pregnant, or breast-feeding.

9. The patient has known-allergy to any of the components of the investigational drug.
10. Participation in another study with an investigational drug within 30 days before Visit 1 or during the study.
11. Use of emergency care treatment more than 3 times in the previous 6 months.
12. The patient is in the opinion of the investigator, is unsuitable to participate in this study for any other reason.
