The goals of preventive therapy are to decrease the frequency, severity, and duration of migraine attacks. Preventive therapy may also improve responsiveness to acute migraine therapy and enhance patients' quality of life. Indications for prophylactic migraine therapy may include:
Frequency of migraine attacks: more than two per month
Duration of individual attacks: longer than 24 hours
Major disruptions in the patient's lifestyle, with significant disability that lasts 3 days or more
Failure or overuse of abortive therapy
Contraindications or inefficacy of symptomatic medications
Use of abortive medications more than twice per week
Preventive therapy may also be indicated in patients who experience hemiplegic migraine or rare headache attacks that produce profound disruption or risk for permanent neurologic injury.
