Does estrogen cause headaches or migraines?

Fluctuating estrogen — not steady estrogen — is what triggers migraines. Oral estrogen pills produce daily peaks and troughs that can worsen migraine for sensitive patients. Transdermal estradiol (patch or gel) delivers a steady serum level and most migraine-with-aura specialists consider it the preferred route. For women with menstrual or perimenopausal migraine, smoothing out hormonal swings with continuous transdermal estradiol often reduces both migraine frequency and severity. Aura is not an absolute contraindication to transdermal HRT, but it is to combined oral contraceptives — these are different molecules at different doses.
