Question
Every month I get horrible migraine
headaches during my menstrual period. Is there
anything that can help?
-- Elizabeth
Answer
You’re not alone. Nearly one in
five women has migraines and about half of those who
seek treatment report that their headaches are
associated with their menstrual periods. Typically the
headaches begin anywhere from two days before the
start of menstruation to the first three days after
the onset. Results of a recent British study published
in the July 27, 2004 issue of Neurology showed
that menstrual migraines are 71 percent more likely to
occur during the two days before periods start.
The same issue of Neurology
also included results of a study showing that taking
the migraine drug frovatriptan (Frova) starting two
days before the anticipated start of migraines
associated with menstruation can prevent the headaches
in some women and diminish their severity and duration
in others. The study (which was sponsored by the
drug’s manufacturer) involved 443 women with
menstrual migraines who took Frova. Menstrual
migraines continued to occur in 67 percent of the
women who took a placebo. Of the women who took Frova
twice a day, 59 percent no longer got the headaches;
of those who took the drug once a day, 48 percent no
longer got headaches. That’s something, but hardly a
miracle cure.
Tennis great Serena Williams
recently announced that she suffers from menstrual
migraines, takes Frova to prevent them and is now
heading an educational campaign to raise awareness
among women that treatment is available for menstrual
migraines. (You can learn more about the campaign at
www.menstrualmigraine.org.)
Frova is one of several drugs called
triptans designed specifically to relieve migraines
(they don’t work for other types of pain). They are
not free of side effects, some of which are serious.
Many alternative treatments are available, both to
relieve and prevent these headaches. For example, a
new study indicates that the herb butterbur (Petasites
hybridus) is effective in preventing migraines.
Patients who took two 75 mg tablets of butterbur
extract cut headache occurrence by an average of 48
percent (compared to 26 percent among patients who got
a placebo). The study was published in the December
28, 2004 issue of Neurology. When buying butterbur, be
careful to choose extracts guaranteed to be free of
pyrrolizidine alkaloids (PAs) that are toxic to the
liver. The supplement should be taken with meals.
Other alternatives include dietary
measures as well as vitamin B-2. A Belgian study
published in the February 1998 issue of Neurologyfound
that 400 mg of B-2 reduces the frequency and duration
of migraines. You’ll need a doctor’s prescription
to get that dosage.
Biofeedback can also help. I urge
you to experiment with these alternatives before
seeking a prescription for Frova.
