June 29, 2005—A common procedure that reduces wrinkles may also help prevent frequent headaches, new findings suggest. Researchers found that giving a series of injections with Botox, already used by millions concerned about looking their best, could cut the incidence of severe migraines by more than half. Those who used Botox also had less need for over-the-counter pain medications when they did suffer a headache.
The results, which were presented at the American Headache Society meeting last week, have been criticized by some migraine experts. "There is no proof that Botox works," said Michael Welch, MD, a neurologist with the Rosalind Franklin University of Medicine and Science in Chicago.
He complained that the new results were based on a review of a previous trial that failed to show Botox could help prevent migraines overall. Finding that it works on a smaller group of patients in the same study is not considered reliable, he said. "We have to be very cautious."
Still, the latest news is bound to add to the strange fortunes of botulism toxin A, a purified food poison that has now become a runaway cosmetic hit as the main ingredient in Botox. The anti-wrinkle treatment was first approved for use against eye muscle disorders, and it has since been found to relieve everything from nerve problems to excess underarm sweat. The toxin quickly gained popularity with so-called "Botox parties," where plastic surgeons injected wrinkled volunteers in front of small gatherings.
