Abstract

Adherence to a therapy, though a key factor for successful treatment, is low among patients with chronic conditions such as migraine. Dose frequency plays a major role in adherence. This study evaluated the impact of having flexible dosing options on acceptance of and adherence to a new migraine preventive therapy class among adults with migraine.In this observational study, two 20-min online surveys were completed: one by physicians currently treating adult patients with migraine and the other by adults with migraine. Both surveys presented the participants with three scenarios: 1) only monthly, 2) only quarterly, and 3) both dosing options of the new medication are available. Physicians estimated the proportion of their migraine patients who would receive the new medication in each scenario. Patients were asked about their dosing preference when either or both options are available. Respondents were asked to rate the likelihood of their acceptance of and adherence to the therapy.400 physicians and 417 US adults with migraine completed the surveys. The availability of both dosing options yielded a significant increase in the proportion of patients expected to receive the new medication. The overall proportion of patients favoring monthly dosing (35%) was similar to the proportion favoring quarterly dosing (40%). Among those who preferred monthly dosing (n =?147), a greater proportion indicated they are more likely to fill the prescription (77% vs 56%, P
