Hormone therapy when you have migraines

Why hormones and migraine are linked

MedlinePlus notes that women are about three times more likely than men to get migraines, and the National Institute of Neurological Disorders and Stroke describes hormone changes around the menstrual cycle and pregnancy as an important trigger. Many women notice attacks before their period, when estrogen falls.

That pattern matters for menopause. It's often the drop and fluctuation of estrogen, rather than the level itself, that provokes attacks. Perimenopause, with its unpredictable hormone swings, can make migraines worse for a while, and some women find their migraines settle after menopause.

Why the birth control rules don't simply transfer

Combined birth control pills use ethinyl estradiol, a potent synthetic estrogen, at doses high enough to suppress ovulation. Guidelines generally advise women who have migraine with aura to avoid combined hormonal contraception, largely because of stroke concerns.

Menopausal hormone therapy usually uses estradiol, the same estrogen the ovaries make, at much lower replacement doses. The risk profile is different, which is why many menopause specialists don't treat migraine with aura as an automatic contraindication to hormone therapy. It's a reason for care, not a reflex 'no.'

Why route and steadiness matter

Transdermal estradiol, given through a patch, gel or cream, produces steadier blood levels than pills and avoids the first pass through the liver. The Menopause Society notes transdermal estrogen may carry a lower blood clot risk than oral estrogen. For women whose migraines respond to estrogen swings, steady delivery is the goal.

For the same reason, clinicians often prefer continuous regimens over cyclical ones that create monthly ups and downs, and start at a low dose.

Aura and stroke risk: the honest picture

Migraine with aura has been associated in research with a modestly higher risk of ischemic stroke, and smoking adds substantially to that risk. The National Cancer Institute notes hormone therapy is also associated with increased stroke risk while it's being taken. So for a woman with aura, the overall stroke picture is worth looking at carefully.

In practice, the biggest modifiable factors are usually smoking and blood pressure. Stopping smoking is the most valuable single step. Controlling blood pressure, cholesterol and blood sugar matters too.

What a careful assessment covers

• Whether your symptoms are true aura (visual zigzags, flashing lights, spreading numbness or speech changes before or during a headache) or something else.
• How often you get migraines, how long aura lasts, and whether the pattern has changed recently.
• Blood pressure, measured properly.
• Smoking status.
• Other cardiovascular risk factors: cholesterol, blood sugar, weight and family history.
• Current migraine medicines and how well they work.

Keeping a headache diary

A simple diary is one of the most useful tools you can bring to a hormone therapy conversation. Note the date, how long each headache lasted, whether aura came first and what it looked like, what you took and whether it worked. If you still have periods, mark those too.

Two or three months of notes before starting gives a baseline. Keeping the diary going after you start makes it easy to see whether hormone therapy is helping, making no difference or making things worse, and gives your clinician concrete information rather than impressions.

If migraines change after starting

Some women find their migraines improve on steady estrogen. Others notice more attacks at first. If headaches worsen, options include switching from oral to transdermal, moving from cyclical to continuous progestogen, or adjusting the dose. A diary helps your clinician see the pattern.

MedlinePlus advises calling your doctor about migraines or sudden vision loss while taking estrogen.

Symptoms that need urgent attention

• Aura for the first time, or aura that looks different from usual.
• Aura lasting longer than about an hour.
• Aura without a headache, appearing for the first time.
• The worst headache of your life, or a sudden, explosive headache.
• Headache with weakness, numbness, drooping face, trouble speaking or loss of vision. Call 911.

Hormone therapy and migraine at HealifyMD

Your clinician will ask detailed questions about your headaches and aura and check blood pressure and smoking before recommending a plan. When estrogen is appropriate, transdermal estradiol is usually preferred. Hormone Therapy for Women at HealifyMD is listed at $349 for the first month, including baseline labs, then $99/month, with estradiol (topical, cream or patch), estriol vaginal cream and progesterone included in the program rather than priced separately. Pricing is confirmed at your eligibility review and other labs are priced separately. Some of these, such as compounded estradiol cream, estriol vaginal cream and compounded progesterone, are compounded medications: they are not FDA-approved, FDA doesn't verify their safety, effectiveness or quality, and they aren't equivalent to branded products.
