Menstruation is a common migraine trigger for women. The good news is that there are a number of options to treat your menstrual migraines, including combination birth control pills.

What is a Menstrual Migraine?

Menstrual migraines strike anywhere from two days before to three days after the start of menstrual flow. While scientists are not completely sure why these attacks occur, there is strong evidence that estrogen, a hormone that helps regulate the menstrual cycle, is involved.

One theory is that the drop in estrogen that occurs right before menstruation excites the brain regions that are involved in migraine, triggering an attack.

While some women experience pure menstrual migraines, which are attacks that only occur during menstruation, most women suffer from menstrual-associated migraines, which are attacks that occur during menstruation, as well as other times of the month.

How are Menstrual Migraines Prevented?

Menstrual migraines can be prevented with long-acting triptans, like frovatriptan or naratriptan. Usually they are taken for 5 to 6 days in the perimenstrual period, which begins two days prior to menstrual flow.

For some women, taking a combination birth control pill -- which consists of both estrogen and progestin-- can reduce the frequency of menstrual migraines. The theory behind using combination birth control pills is that the pills prevent any significant estrogen drop from occurring in your cycle.

Am I a Candidate for Combination Birth Control Pills for My Menstrual Migraines?

Certain factors of your medical history will need to be considered before your doctor will prescribe combination birth control pills. For instance, according to the American College of Obstetricians and Gynecologists, a woman with migraines may be prescribed combination estrogen-progesterone birth control only if she has migraines without aura.

This is because having migraine with aura is associated with an increased risk of stroke, and this risk may be further increased by taking a combination birth control pill. Other factors that contradict your ability to take combination birth control include smoking, age 35 or over, or certain health conditions, like high blood pressure or a history of a blood clot.

If your doctor does prescribe combination birth control pills for your migraines, you may take the pills continuously to keep your estrogen levels constant. This means skipping the placebo pills if you have a 28-day pill packs, or continuously taking them if you have 21 day pill packs.  

Though some continuous birth control methods can help prevent menstrual migraines, it should be noted that many people suffer attacks immediately after the pills are stopped, or during pill-free points of the month.

Bottom Line

It's important to keep in mind that combination birth control pills may not be the best method to treat your migraines.

Please consult with your doctor to determine what the best treatment strategy is for you. Your doctor may ask you to keep a diary of your attacks for several months, noting each time you experience a migraine and the dates of your menstrual flow. This way your doctor can decide whether few, some, or most of your migraines are triggered by menstruation
