Contraception
-
Combined hormonal contraception might worsen migraine in sensitive women, especially during the free-hormone interval, and raise concerns about the vascular risk. The characteristics of a contraceptive pill containing estradiol valerate/dienogest (E2V/DNG) might be of potential benefit in women with menstrually related migraine (MRM) who choose to use oral contraception for birth control. ⋯ The present diary-based pilot study indicates that the use of a pill containing EV2/DNG for six cycles has a positive effect in women with MRM and suggests an association between dysmenorrhea with COCs use as a potential feature of refractory head pain.
