The goal was to
help fade frown lines, but a number of studies have
found that a cosmetic treatment could have medical
benefits.
Tuesday at the annual gathering of the American Headache
Society, presenters are releasing findings of 13 studies
that indicate Botox, a wrinkle-smoothing drug, rid
a number of patients of severe headaches.
One particular project suggests that people plagued
with headaches who also had Botox injections for cosmetic
reasons suffered from fewer migraines, experienced
a reduction in the disabling effects of migraines
and used less pain medication.
Doctors who participated in the studies said they
were encouraged about the relatively few risks of
using Botox to curb headache pain.
"The biggest advantage
to Botox is its lack of side effects, especially
compared to other medications," Dr. William
Ondo of the Baylor College of Medicine said in an
AHS press release. "It really is extremely
safe and appears to be very effective for some people."
Taking a medication to treat an ailment for which
the Food and Drug Administration has not approved
it is known as "off label use," and a number
of drugs are used in that manner.
Results from tracking 650 migraine and tension headache
sufferers suggests that Botox has off-label benefits.
But it won't be the first off-label use of Botox.
Doctors have use it in treating crossed eyes, twisted
necks and stiff muscles
According to the American Headache Society, about
28 million Americans endure migraines and 10 million
more experience chronic daily headaches, which means
they hurt at least 15 days each month.
Handling headache
Doctors administer Botox by injecting
it as a liquid under patients' skin. Patients usually
get about 10 to 25 shots in the head, neck and shoulders.
The small needle feels like a pin prick or bug bite.
It is not really clear how Botox curbs headache pain
and stiffness. Researchers think Botox blocks sensory
nerves that relay pain messages to the brain and relaxes
muscles, making them less sensitive to pain.
According to results from a study conducted at Wake
Forest, Botox side effects are minimal. Doctors found
a small risk the skin around the injection site would
droop temporarily. The problem is avoidable if physicians
know what areas to avoid.
And sometimes patients experienced slight bruising,
bleeding at the injection site or a burning sensation.
Examining results
More than half of the 48 patients in a study at a
Mayo Clinic in Scottsdale, Arizona, said their migraine
occurrences dropped by 50 percent or more.
Of the ones who had a positive response, 61 percent
said they had headaches less frequently and almost
30 percent said the headaches were less severe.
At the Baylor College of Medicine Headache Clinic,
58 patients participated in a controlled trial. Some
received Botox and others had placebos.
After three months, 55 percent of the patients who
received Botox reported at least moderate improvement
in their headaches. Two of the 29 who got the placebo
water injections reported the same results.
The headache and Botox connection began emerging
in 1992 when a California physician noted his patients
who got Botox injections said they were having fewer
headaches.
