The primary goals of prophylactic drugs are to prevent migraine attacks and to reduce the frequency and severity of attacks. Half of all patients experience at most a 50% reduction in migraines. Most prophylactic migraine medications have potential adverse effects; therefore, consider only patients with 1-2 attacks per week (4 or more headache days monthly) for prophylaxis.
