Botox for Chronic Migraine Prevention is Legalized
In an official statement issued October 15, 2010, FDA recommends the injection every 3 months for migraine prevention. The injection point is around the neck and head.
But the effects of botox is said to only be efficacious for chronic migraine. Other type of headaches or migraines that lasted less than 14 days can not be prevented by the drug which have generic name, onabotulinumtoxinA.
The FDA also warned of possible side effects that could arise. In clinical trials, botox injections cause neck pain and headache in 1 percent of patients while the same phenomenon experienced only 0.3 percent of patients who received placebo.
This is not the first time the use of Botox for medical purposes is approved by the FDA. Previously, the same drug was already approved to cope with strabismus and blepharospasm, 2 types of eye muscle disorders.
“In migraine, the efficacy of botox are not too powerful. But no matter how small, its influence can be very useful when someone can get back to activities,” said Dr. Elizabeth W. Loder, professor of neurology at Harvard University, according to Reuters.
Migraines are sometimes accompanied by nausea, vomiting and increased sensitivity to light or sound. It could be said chronic if it lasts at least 15 days with a duration of at least 4 hours a day.
World Health Organization (WHO), puts migraine in 19th place in the list of diseases which disturbs activity. Compared to men, women are 3 times more prone to get the symptoms.
