Quick answer: A hormonal migraine is a migraine attack triggered by shifting hormone levels, most often the drop in estrogen just before and during a period. These attacks tend to last longer and be harder to treat than other migraines. Options now range from timed short-term prevention and hormone strategies to newer CGRP-targeting medicines.
Migraine is about three times more common in women than in men, and hormones are a big reason why. Many women notice attacks cluster around their period, flare in perimenopause and ease during pregnancy or after menopause. If that sounds familiar, you may have hormonal (menstrual) migraine, and it is very treatable.
What causes hormonal migraines?
The leading explanation is estrogen withdrawal: the natural fall in estrogen before a period triggers attacks in people who are sensitive to it. The change matters more than a low level, which is why the hormone-free week of many birth-control pills can also bring on "pill-break" migraines.
Migraine is now understood as a disorder of the brain's pain-signaling network, not a blood-vessel problem. Estrogen influences this network and the release of CGRP, a protein that drives migraine pain. This is why CGRP-targeting medicines now play a role in treatment.
Types of hormonal (menstrual) migraine
The International Classification of Headache Disorders (ICHD-3) defines the menstrual window as 2 days before through the first 3 days of bleeding. Attacks must fall in that window in at least 2 of 3 cycles to count.
|
Type |
When attacks happen |
How common |
|---|---|---|
|
Menstrually related migraine |
During the menstrual window and at other times |
Most common; about 68% of menstrual migraine in a 2023 Danish study (Chalmer et al.) |
|
Pure menstrual migraine |
Only during the menstrual window |
Uncommon; under 10% of women with migraine in most studies |
Menstrual attacks feel like other migraines with throbbing pain, nausea, and sensitivity to light and sound, but are typically longer (often 2–3 days), more severe, more likely to return after treatment and less responsive to usual medicines. Most occur without aura.
How hormonal migraine is diagnosed
There is no lab or imaging test. Your doctor will ask you to keep a headache diary for at least three menstrual cycles, tracking headache days, symptoms, medicines and period dates. They will also ask whether you have aura, because that changes which hormonal treatments are safe.

How are hormonal migraines treated?
Treatment usually layers medicine to stop attacks, short-term prevention timed to your period and, if attacks are frequent, ongoing prevention. No drug is yet FDA-approved specifically for menstrual migraine, so doctors schedule proven migraine treatments around your cycle.
1. Acute treatment
- NSAIDs such as naproxen, which also target menstrual prostaglandins.
- Triptans such as sumatriptan or rizatriptan, the standard for moderate to severe attacks. A 2024 meta-analysis confirmed they outperform placebo for menstrual migraine (Khoo et al., Journal of Headache and Pain).
- Gepants (rimegepant, ubrogepant, zavegepant), CGRP blockers that don't narrow blood vessels, an option when triptans aren't suitable.
Treat early. Because menstrual attacks tend to return, your doctor may suggest a second dose or a longer-acting option.
2. Short-term ("mini") prevention
If your periods are regular, you can take a preventive for 5–7 days around your period instead of daily. This is often a long-acting triptan (frovatriptan or naratriptan) or a scheduled NSAID, starting about 2 days before bleeding.
New in 2026: In AbbVie's phase 3 LUNA trial, atogepant (Qulipta) taken for 7 days starting 3 days before a period cut perimenstrual migraine days by 1.2 versus 0.4 with placebo (NeurologyLive). It is the first CGRP-targeted treatment to succeed in a menstrual migraine trial; this cyclical use is not yet FDA-approved.
3. Ongoing prevention
If you also get migraines at other times of the month, continuous prevention may make more sense:
- CGRP-targeting medicines — monthly or quarterly injections or infusions (erenumab, fremanezumab, galcanezumab, eptinezumab) or pills (atogepant, rimegepant). Since 2024 the American Headache Society has listed them as a first-line option, with no need to fail older drugs first (AHS position statement).
- Traditional preventives such as certain blood-pressure, antidepressant or anti-seizure medicines.
- Botox® for chronic migraine (15+ headache days a month), and procedural options for carefully selected patients who don't respond to medication. [Link to treatments page]
4. Hormonal approaches
- Continuous or extended-cycle birth control (skipping the placebo week) removes the monthly estrogen drop, for people without aura only.
- Estrogen gel or patch around the period can help some, though evidence is limited and attacks may shift to when it stops.
- Progestin-only methods (implant, hormonal IUD, progestin-only pill) are considered safe with or without aura.
Safety note on aura: If you have migraine with aura, avoid estrogen-containing birth control (combined pill, patch or ring). The CDC's 2024 U.S. Medical Eligibility Criteria rate it an unacceptable health risk because aura and estrogen together raise stroke risk.
5. Lifestyle support
Around your period especially, keep regular sleep and meals, stay hydrated, limit alcohol, exercise regularly and manage stress. Track food triggers in your diary rather than cutting out whole food groups, and ask your doctor before starting supplements such as magnesium.
Hormonal migraines through life stages
|
Life stage |
What usually happens |
|---|---|
|
Pregnancy |
Most improve in the 2nd and 3rd trimesters as estrogen stays high and steady, with remission in roughly 77–79% of women without aura in one study. Attacks often return after delivery. |
|
Perimenopause |
Often the worst stretch: erratic estrogen and shorter cycles bring more frequent, harder attacks. |
|
Menopause |
About two-thirds of women improve after natural menopause; surgical menopause tends to worsen migraine at first. |
Migraine is not a reason to avoid menopausal hormone therapy. Low-dose transdermal estrogen (patch or gel) is preferred because it keeps levels steady.
When to see a doctor
See a migraine specialist if attacks disrupt work or family life, over-the-counter medicine isn't enough, or you need acute medicine more than 2–3 days a week. Get emergency care for a sudden "worst headache of your life," headache with weakness, confusion or trouble speaking, aura lasting over an hour, or a severe new headache during pregnancy or after delivery.
Frequently asked questions
Can birth control stop menstrual migraines?
For some people without aura, continuous combined birth control prevents the estrogen drop that triggers attacks. With aura, progestin-only methods are the safe choice.
Do hormonal migraines go away after menopause?
Often. About two-thirds of women improve once natural menopause is established, though perimenopause can be worse first.
How do I know if my migraines are hormonal?
Track headaches and periods for three cycles. If attacks land in the menstrual window in at least two of them, talk to your doctor.
