Botox Approved to Treat Chronic Migraines
October 16, 2010
(ChattahBox Health News) – The Food and Drug Administration has approved the use of anti-wrinkle injection Botox to treat chronic migraines. The green light was based on two studies funded by its manufacturer, Allergan, which involved 1,384 adult patients who received Botox injections experienced between 7.8 and 9.2 fewer days of headaches than those who didn’t. Chronic migraines , defined as those that occur 15 or more days per month, “are one of the most disabling forms of headache,” said Dr. Russell Katz, a member of the FDA’s drug-evaluation team, and they affect about 3.2 million Americans. The drug, which is a purified form of the deadly toxin that causes botulism, whose generic name is onabotulinumtoxinA, has not been proven to prevent migraines that occur with less frequency, is also used to treat various muscle-spasm conditions, such as severe neck spasms.
