Abstract Objective We sought to assess factors associated with the frequency of self‐reported prescription opioid use in persons with migraine, including demographic variables, comorbidities, headache characteristics, and patterns of consultation. Background Despite the dose‐dependent effect of opioids on migraine progression and the association with negative outcomes, migraine treatment often includes opioids. The Migraine in America Symptoms and Treatment Study focuses on individuals with migraine who receive prescription acute medications, including those receiving and those not receiving opioids. Methods This web‐based panel survey identified people in the United States with migraine using a validated screener. This analysis stratified people with migraine into 4 groups based on days of monthly opioid use: non‐opioid users, ≤3 days, 4‒9 days, and ≥10 days per month. Results Of 15,133 respondents with migraine, 4701 (31%) reported acute prescription medication use for headache/migraine in the previous 3 months (mean age 45 years, 71.6% [3367/4701] female), of whom 32.5% (1528/4701) reported opioid use. About one‐third of respondents with primary care or neurology consults in the prior 6 months reported receiving an opioid, and more than half of respondents (209/391, 53.5%) with a pain clinic consultation did so. Models compared those using opioids ≤3 days/month (879/4701, 18.7%), 4‒9 days/month (304/4701, 6.5%), ≥10 days/month (345/4701, 7.3%) to non‐opioid users (3173/4701, 67.5%). Compared to non‐opioid users, infrequent users (≤3 days/month) were more likely to be male and less likely to have chronic migraine or to screen positive for anxiety and depression; and frequent opioid users (the 4‒9 days/month and the ≥10 days/month groups) were more likely to be male, to smoke, to be obese, to report greater pain interference, to have moderate to severe disability, to have symptoms of anxiety and depression, to use fewer triptans and nonsteroidal anti‐inflammatory drugs, and to have poor acute treatment optimization. Conclusion Among prescription medication users, this cross‐sectional analysis shows that increasing use of prescription opioids is associated with male gender, chronic migraine, more severe disability, anxiety and depression, poor acute treatment optimization, and treatment in a pain clinic.

Objectives The objectives of this study were to determine the rates of nausea, phonophobia, and photophobia reported overall and as the most bothersome symptom (MBS) in individuals with migraine and to identify individual characteristics associated with each of the 3 candidate MBSs. Background The MBS has emerged as an important coprimary efficacy endpoint in clinical trials of acute treatments for migraine, as recommended by the Food and Drug Administration. The current understanding of how persons with migraine designate an associated symptom as the most bothersome has been assessed primarily in the context of randomized trials. Methods Respondents (n = 95,821) in the cross‐sectional, observational Migraine in America Symptoms and Treatment (MAST) study were adults (aged ≥18 years) recruited from a US nationwide online research panel. A validated diagnostic screener identified 15,133 individuals who met modified International Classification of Headache Disorders (ICHD)‐3 beta criteria for migraine and reported at least 1 monthly headache day (MHD) over the previous 3 months. The survey ascertained sociodemographic variables, headache‐related disability, MHDs, cutaneous allodynia, medication overuse, a migraine symptom severity score, pain interference, noncephalic pain, anxiety and depression symptoms, visual aura over the previous year, and acute treatment optimization. The current analysis is based on respondents who also completed a 6‐month follow‐up assessment that included questions about their most bothersome headache symptom. Results A total of 7518 respondents completed the 6‐month follow‐up, and 6045 met inclusion criteria and were included in the analysis. The mean age of respondents was 47 (SD 13.4) years, 76.0% (4596/6045) were women, and 84.8% (5103/6017) were white. Among all respondents, 64.9% reported all 3 migraine symptoms. The MBS was photophobia in 49.1% (2967/6045), nausea in 28.1% (1697/6045), and phonophobia in 22.8% (1381/6045). Respondents reporting photophobia as the MBS were more likely to be men, to be obese, and to report visual aura. Those reporting nausea as the MBS were more likely to be women, to have lower incomes, and to report lower levels of treatment optimization. Respondents reporting phonophobia as the MBS were more likely to have cutaneous allodynia and less likely to have visual aura. Conclusion Most people with migraine in the MAST observational study reported all 3 cardinal symptoms of nausea, photophobia, and phonophobia. As in clinical trials, the most common MBS was photophobia. Patient profiles differed among the groups defined by their MBS.
