Migraine in Women

Migraine in Women · G43.9

Women are three times more likely than men to experience migraine, with hormonal fluctuations in estrogen playing a central role in menstrual migraine, pregnancy-related changes, and menopausal migraine patterns.

2026-03-29

At a Glance

Migraine affects approximately 18% of women compared to 6% of men. Estrogen withdrawal is the primary trigger for menstrual migraine, which occurs in 60% of female migraineurs. Pure menstrual migraine (without aura, days -2 to +3 of menstruation) is treated with perimenstrual triptans or naproxen. During pregnancy, migraine improves in 60-70% of women, particularly in the 2nd-3rd trimesters. Acetaminophen is the primary safe analgesic during pregnancy. Migraine with aura combined with estrogen-containing contraceptives doubles ischemic stroke risk. Menopausal migraine may worsen during perimenopause before improving after menopause.

Definition and Overview

Migraine affects approximately 18% of women compared to 6% of men, a three-fold difference that emerges after puberty and persists until menopause. Hormonal fluctuations, particularly estrogen withdrawal, play a central role in this sex difference and influence migraine patterns throughout a woman's reproductive life [1].

Hormonal Mechanisms

Estrogen withdrawal is the primary trigger for menstrual migraine. The rapid decline in estrogen levels during the late luteal phase triggers changes in serotonin metabolism, prostaglandin release, and trigeminovascular sensitization [2].

Stable high estrogen levels (pregnancy 2nd-3rd trimester) are protective, while fluctuating levels (perimenstrual, perimenopause) promote migraine. Progesterone has minimal direct effect on migraine but modulates estrogen effects.

Menstrual Migraine

Pure menstrual migraine (PMM): attacks exclusively during days -2 to +3 of menstruation without aura. Menstrually-related migraine (MRM): attacks during the perimenstrual window and at other times of the month [1].

Perimenstrual prevention: frovatriptan (2.5 mg BID, days -2 to +3), naproxen sodium (550 mg BID), or estradiol gel/patch during the late luteal phase can prevent menstrual attacks [3].

Pregnancy and Breastfeeding

Migraine improves in 60-70% of women during pregnancy, particularly in the 2nd and 3rd trimesters. Improvement is greatest for migraine without aura. Migraine with aura may persist or worsen [4].

Safe medications during pregnancy: acetaminophen (first-line), metoclopramide for nausea. Triptans: sumatriptan has the most safety data. NSAIDs: avoid in the 3rd trimester. Preventive options: magnesium, propranolol, amitriptyline (with caution).

During breastfeeding: sumatriptan and ibuprofen are considered compatible. Avoid ergotamine and aspirin.

Oral Contraceptives and Migraine

Migraine with aura combined with estrogen-containing contraceptives increases ischemic stroke risk 2-4 fold. Combined oral contraceptives are contraindicated in migraine with aura [5]. Progestin-only methods are safe alternatives for women with migraine with aura.

For migraine without aura, combined contraceptives may be used with careful risk assessment. Continuous or extended-cycle formulations may reduce menstrual migraine by minimizing estrogen withdrawal.

Menopause

Migraine often worsens during perimenopause due to erratic hormonal fluctuations. After menopause (stable low estrogen), migraine typically improves. Hormone replacement therapy (HRT) with stable estrogen delivery (transdermal patch) may help perimenopausal migraine while oral HRT may worsen it.
