Headaches During Menopause: Why Migraine Flares, How Much Magnesium, Riboflavin, Water and Cold Packs Help, and Which Headaches Need Urgent Care

A question from a menopause group: what actually helps these headaches?

A member of a menopause support group asked what could ease the headaches she had been getting more often lately.
Several members shared what worked for them: magnesium together with B vitamins, sipping water often, a cold pack on the neck or forehead,
and one suggestion to first notice when and after what the headaches start before buying vitamins.

1. Why headaches increase around menopause

Estrogen swings, not just the decline

A classic study (Somerville 1972)
showed that a drop in estrogen triggers menstrual migraine.
In perimenopause, estrogen rises and falls unpredictably — high some months, plunging in others — so migraine can flare more often.
A review (MacGregor 2018)
concludes that estrogen withdrawal triggers migraine without aura, while very high estrogen levels can trigger aura.

Data from a survey of 3,664 women

The AMPP survey of women with migraine aged 35–65 (Martin 2016)
found headaches on 10 or more days a month in 8.0% of women with regular periods, 12.2% in perimenopause and 12.0% after menopause.
Perimenopause carried about 1.62 times the odds of frequent headache, still 1.42 times after adjusting for depression, weight and medication overuse.

After menopause, it often improves

A systematic review (Ripa 2015)
found that in the general population migraine often improves after menopause, more so after natural menopause than after surgical removal of the ovaries.
Some women with severe migraine treated at headache clinics do not improve. The hardest stretch is the transition, which often lasts several years.

Common contributors at this age

• Short sleep or night waking from hot flashes — sleep and migraine affect each other in both directions (Vgontzas 2018)
• Stress and tight neck and shoulder muscles — tension-type headache can overlap with migraine
• Frequent painkiller use — can make headaches more frequent (see section 4)
• Irregular coffee intake — stopping suddenly can cause headache; keep a similar amount each day and skip it in the afternoon
• Skipped or late meals and low fluid intake — common personal triggers

2. Non-drug relief: what has evidence

Start with a headache diary

The advice to “observe before buying vitamins” matches good headache care. For 1–2 months, record which days you have pain, how long and how bad,
how many hours you slept, what you ate or drank beforehand, whether your period came, and how many days you took painkillers.
This helps you find your own triggers and helps a doctor separate migraine from medication-overuse headache.

Water: some benefit, not the main treatment

In a randomized trial (Spigt 2012)
of 102 people with frequent headaches who drank less than 2.5 litres a day, one group added 1.5 litres daily for 3 months.
Quality-of-life scores improved by 4.5 points and 47% felt much better versus 25% of controls, but the number of headache days did not fall.

A cold pack on the neck

A crossover trial in 55 people with migraine (Sprouse-Blum 2013)
used a neck wrap with frozen gel packs over the carotid arteries at headache onset. Pain fell by about 32% at 30 minutes,
while the control condition saw pain rise. The study was small, but the method is cheap with few side effects. Wrap it in a thin cloth, never put ice directly on skin, and keep each session to 20 minutes or less.

Fixed sleep and wake times

Both too little and too much sleep can trigger migraine, and migraine itself worsens sleep (Vgontzas 2018).
Go to bed and get up at the same time every day, weekends included. If hot flashes badly disturb sleep, see
Perimenopause: insomnia and missed periods

Exercise and relaxation training

A randomized trial (Varkey 2011)
in 91 people with migraine compared 40 minutes of exercise 3 times a week, relaxation training, and a preventive migraine drug for 3 months.
All three reduced attacks by about one a month, with no significant difference between groups. Exercise is therefore an option for people who do not want a daily preventive pill.
Start with brisk walking or moderate cycling and warm up well, because sudden hard effort can trigger attacks in some people.

Thai massage and acupuncture

A Thai trial in 60 people with chronic tension-type headache (Damapong 2015)
found that 45-minute court-type Thai massage twice a week for 4 weeks reduced pain more than a low-dose preventive drug.
For migraine, a Cochrane review (Linde 2016)
of 22 trials and 4,985 people found headache frequency at least halved in 41% with acupuncture versus 17% without it,
but compared with sham acupuncture the difference was small (50% vs 41%).

3. How much magnesium and riboflavin help

Evidence level in guidelines

The American Academy of Neurology and American Headache Society guideline (Holland 2012)
rates magnesium, riboflavin (vitamin B2) and some NSAIDs as “probably effective” for migraine prevention (Level B).
That means good studies support them, but not enough for the top rating.

Magnesium

A meta-analysis (Chiu 2016)
of 10 randomized trials with 789 people found that oral magnesium reduced both the frequency and intensity of migraine, although some trials had weak randomization.
Studies used several forms such as citrate, oxide and glycinate; no form has been shown to work better for migraine, so choose one you tolerate.
Study doses are usually about 400–600 mg of elemental magnesium a day, above the 350 mg/day supplement upper limit for the general public set by the
NIH Office of Dietary Supplements,
so use these doses with advice from a doctor or pharmacist.

Riboflavin (vitamin B2)

A randomized trial (Schoenen 1998)
gave riboflavin 400 mg a day or placebo for 3 months to 55 people with migraine.
Headache days fell by at least half in 59% versus 15%. Side effects were few, such as loose stools and frequent urination.
Urine turns bright yellow, which is harmless (more: NIH ODS: Riboflavin).
This dose is dozens of times higher than a typical B-complex tablet, so one multivitamin may not match the study effect.

Cautions before taking them

• Kidney disease — the kidneys clear less magnesium, so it can build up; do not take high doses without a doctor
• Loose stools — the most common magnesium side effect, especially with citrate and oxide; start low and increase slowly
• Medicines to space apart — tetracycline and quinolone antibiotics and bisphosphonate osteoporosis drugs should be taken at least 2 hours apart from magnesium
• Combination products — check the actual magnesium and riboflavin per tablet, not the product name, and do not stack several products

4. Painkillers, blood pressure and hormones: using them safely

Painkillers are not the enemy, but count the days

The International Classification of Headache Disorders, 3rd edition (ICHD-3)
states that in people with an existing headache disorder, using simple painkillers such as paracetamol or NSAIDs like ibuprofen or naproxen
on 15 or more days a month, or triptans or combination painkillers on 10 or more days a month, for more than 3 months,
can cause medication-overuse headache. A review (Diener 2019)
reports a 1-year prevalence of 1–2%, more common in women, treated with education, supervised reduction or withdrawal of the overused drug, and preventive treatment.

When to discuss preventive treatment

If headaches occur on several days a month, stop you from working, or push painkiller use toward the limits above, see a doctor about migraine prevention.
There are several preventive drug classes; the doctor chooses based on other conditions such as high blood pressure, insomnia or hot flashes.
For painkiller timing in cycle-related migraine, see
Severe headache and nausea before your period: menstrual migraine and medication

Blood pressure and headache

The US blood pressure guideline (Whelton 2017)
defines a hypertensive emergency as blood pressure above 180/120 mmHg with new organ damage, such as to the brain, heart, kidneys or eyes.
Mild to moderate high blood pressure is usually symptom-free, so do not assume every headache comes from blood pressure, or that a normal reading means a headache is harmless.

A new headache after 50

The SNNOOP10 red-flag list (Do 2019)
treats a new headache or a change in pattern as a sign to look for another cause.
Giant cell arteritis occurs almost only in people aged 50 and over. It causes temple pain, scalp tenderness, jaw pain when chewing,
and can cause blindness if treatment is delayed (Bosch 2024).
A woman who starts getting a headache like this for the first time after 50 should not assume it is just menopause.

Hormone therapy and migraine

A review (Ripa 2015)
found that in observational studies hormone therapy was linked with worse migraine in some women.
Meanwhile (MacGregor 2018)
advises that if hormones are needed for hot flashes, use the lowest dose of transdermal estrogen (patch or gel) that controls symptoms to keep levels stable.
Migraine with aura does not rule out physiological doses of natural estrogen, unlike combined contraceptive pills, and continuous rather than cyclical progestogen is preferred.
The position statement (NAMS 2022)
stresses individual benefit-risk decisions with a doctor.

5. Comparing ways to handle menopause headaches

This table compares common options, from self-care to doctor-prescribed medicines, using drug classes and generic names only. Shown as cards on mobile.

6. Shared beliefs: how accurate are they?

• “Migraine is caused by abnormally widened brain blood vessels” — an old idea; migraine now is understood to start in the brain and nerves, with vessel changes following
• “Low water intake thickens the blood and causes headache” — dehydration can trigger headache, but extra water in a trial did not reduce headache days; drink enough, no need to force large amounts
• “Painkillers damage everyone’s liver and kidneys, so never take them” — occasional use at the label dose is safe for most people; what to avoid is use on more than 10–15 days a month or above the maximum dose
• “Magnesium stops a headache straight away” — oral magnesium is for prevention and needs about 3 months; it is not a rescue painkiller
• “Blood pressure over 140/90 means go to the emergency room now” — it is the high blood pressure threshold that needs a doctor visit; the emergency level is 180/120 or higher with symptoms
• “Buy vitamins first when headaches start” — observe and keep a diary first, because some headaches come from sleep, coffee or frequent painkillers and can be fixed without buying anything

Frequently Asked Questions (FAQ)

Why do headaches become more frequent and migraine flare during menopause?

In perimenopause, estrogen rises and falls unpredictably, and a drop in estrogen is a well-known migraine trigger. A survey of 3,664 women with migraine found that 12.2% of perimenopausal women had headaches on 10 or more days a month, compared with 8.0% of women with regular periods. Poor sleep from hot flashes and stress add to this. The good news is that population studies show migraine often improves once menopause is complete.

How much do magnesium and riboflavin help prevent migraine, and how much should I take?

The 2012 American Academy of Neurology and American Headache Society guideline rates both as probably effective for migraine prevention (Level B evidence). In a trial of riboflavin (vitamin B2) 400 mg a day for 3 months, headache days fell by at least half in 59% of patients versus 15% on placebo. Magnesium studies usually use about 400–600 mg a day, which is above the general supplement upper limit, so check with a doctor or pharmacist first, and people with kidney disease should not take it on their own. Both are for prevention, not for stopping an attack, and need about 3 months of daily use before judging the effect.

How can I relieve menopause headaches without medication?

Options with research support include a cold pack on the neck at the start of a headache, which cut pain by about 32% within 30 minutes in one trial; going to bed and waking at the same time; aerobic exercise for 40 minutes 3 days a week, which reduced migraine frequency about as much as a preventive drug in one trial; court-type Thai massage for tension-type headache; and acupuncture for migraine. Keep a diary of headache days, food, sleep and painkiller use to find your own triggers.

How often can I take painkillers before risking medication-overuse headache?

Under the International Classification of Headache Disorders, 3rd edition, using simple painkillers such as paracetamol or NSAIDs on 15 or more days a month, or triptans or combination painkillers on 10 or more days a month, for more than 3 months can make headaches more frequent because of the medicine itself. Painkillers are fine, but count the days you use them. If you are close to these limits, see a doctor about preventive treatment rather than stopping or increasing medicines on your own.

Does drinking more water really reduce headaches?

Somewhat. In a randomized trial, people with frequent headaches who drank less than 2.5 litres a day were asked to drink an extra 1.5 litres daily for 3 months. Quality of life improved and 47% felt much better versus 25% of controls, but the number of headache days did not fall. Extra water improved how people felt, but did not reduce headache days, so it is an add-on, not the main treatment. People with heart failure or kidney disease on a fluid limit should follow their doctor.

Do I need to go to hospital right away if my blood pressure is 140/90 with a headache?

Not to the emergency room if there are no other symptoms. 140/90 is the threshold for high blood pressure, not for an emergency. Re-measure after sitting for 5 minutes, record readings over several days and book a doctor visit. Go to hospital right away if blood pressure is 180/120 or higher with a severe headache, blurred vision, chest pain, breathlessness, confusion or weakness. Mild to moderate high blood pressure rarely causes headache, so do not assume every headache comes from blood pressure.

Does hormone therapy help migraine or make it worse?

It can go either way. Observational population studies link hormone therapy with worse migraine in some women. Migraine and menopause specialists advise that if hormones are needed for hot flashes, the lowest dose of transdermal estrogen (patch or gel) that controls symptoms keeps hormone levels stable and may reduce estrogen-withdrawal migraine. Migraine with aura does not rule out physiological doses of natural estrogen, unlike combined contraceptive pills. The decision should be made individually with a doctor.

Which headaches need hospital care right away?

Go to hospital or call emergency services (1669 in Thailand) right away for a sudden severe headache that peaks within a minute, a headache with weakness, facial droop, slurred speech, blurred or double vision, fever with a stiff neck, seizure or confusion. A new type of headache that starts after age 50, especially with scalp tenderness, jaw pain when chewing or visual changes, needs a same-day medical review because giant cell arteritis can cause blindness. A change in your usual pattern, steadily worsening headaches, or headaches that wake you at night with vomiting need a prompt appointment.

The science in brief

Summary by Asst. Prof. Dr. Norawit Raatpiboon:
Migraine starts in a brain that is more sensitive to triggers than usual. When triggered, the trigeminal nerve system supplying the brain’s coverings releases CGRP,
causing inflammation around nerve endings and sending pain signals to the brainstem and sensory brain areas. This system becomes more sensitive the more often it fires.
Estrogen helps regulate serotonin and trigeminal sensitivity, so a rapid fall in estrogen lowers the threshold for an attack.
In perimenopause, with hormones swinging unpredictably, the brain meets estrogen drops more often than before, so attacks become more frequent;
after menopause, hormone levels are low but stable, and this trigger fades.
Magnesium blocks NMDA receptors and reduces nerve-cell excitability, while riboflavin supports mitochondrial energy production, which appears reduced in the brains of people with migraine.
Overusing painkillers makes the brain’s pain-control system adapt and become more sensitive, so headaches become more frequent even as more pills are taken.
