Prevention of migraine.

Preventing migraines, decreasing their frequency, intensity, or severity, or even making them more responsive to acute medications are important goals for every migraine sufferer. Ideally, the choice of preventive strategy should be matched to the individual patient. Many times preventive medications can help treat another problem, such as high blood pressure, depression, anxiety, or trouble sleeping. A preventive strategy is best formulated with a team approach involving the patient and caregiver, balancing effectiveness, side effects, and potential nonmigraine benefits.
