Menstrual migraine: A review of prophylactic therapies

Menstrual migraine is commonly encountered in women who are experiencing attacks of migraine without aura. It remains controversial whether attacks of menstrually associated migraine are more severe and have a longer duration than non-menstrually associated attacks. The pathogenesis of menstrual migraine is not understood completely, but it may be related to estrogen withdrawal or prostaglandin release. Preventative therapies may be considered in those who have failed abortive medications or have attacks lasting longer than 2 days. They can be administered short-term during the perimenstrual time period or continuously throughout the menstrual cycle. Short-term prophylactics should be tried first because menstrual migraines generally last for 1 to 4 days only. Continuous prophylactics may be considered in those with attacks refractory to short-term therapies. Copyright © 2004 by Current Science Inc.
