I am 48 and perimenopausal. I never had a migraine until my hormones started to change; now I get 6 or so migraines per month. They are obviously linked to hormonal change because I am having 6 or so periods each month too! A compounding factor is altitude; I live at 6,000 feet and never have had a migraine at sea level. My doctor prescribed Yaz to normalize my periods, but i went off after three months because I am skeptical of the dangerous side effects of Yaz. Fortunately imitrex is usually effective during a migraine episode, and I am looking forward to menopause!
