I asked this question as Ravitz was putting the first needles in my face, which was probably a mistake as I get anxious easily. However, she assured me that the side effects of Botox typically don't happen at the doses prescribed for migraines, and even if the scary-sounding side effects you read about online do occur (such as one-side paralysis and eye droops), they aren't particularly dangerous and last four to six weeks.
In the mid- to late-1990’s dermatologists were the first to report headache relief to migraineurs who were receiving BOTOX injections to reduce facial (forehead) wrinkles. Initially there was significant controversy about whether BOTOX really did help migraine patients. The use of BOTOX for treatment of tension headaches was studied and found to be no more effective than placebo. With migraines, it was more complex. In 2009 the data showed that BOTOX injected in particular areas of the head and neck in patients who met the International Classification of Headache Disorders criteria for chronic migraine provided sufficient benefit to recommend the treatment modality. In 2010, the FDA approved BOTOX for chronic migraine and recommended the protocol of injections and treatment frequency that had been successful in the studies.
The cosmetic benefits came to light in the 1990s by happy coincidence. “The aesthetic indications were purely happenstance,” says board-certified surgeon and clinical professor Seth L. Matarasso, MD, who has been treating his clients with Botox since the 1990s but is not affiliated with the brand. “Dr. [Jean] Carruthers was working with patients with strabismus...[and] with diplopia [double vision], and her patients were coming in and saying, ‘Gee, my wrinkles are better.'" Soon enough, doctors were using Botox for what it is most commonly associated with today — nixing lines.
Individuals with peripheral motor neuropathic diseases, amyotrophic lateral sclerosis (ALS), or neuromuscular junction disorders (eg, myasthenia gravis or Lambert-Eaton syndrome) should be monitored when given botulinum toxin. Patients with known or unrecognized neuromuscular disorders or neuromuscular junction disorders may be at increased risk of clinically significant effects including generalized muscle weakness, diplopia, ptosis, dysphonia, dysarthria, severe dysphagia, and respiratory compromise from therapeutic doses of BOTOX® (see Warnings and Precautions).
Do not receive BOTOX® Cosmetic if you: are allergic to any of the ingredients in BOTOX® Cosmetic (see Medication Guide for ingredients); had an allergic reaction to any other botulinum toxin product such as Myobloc® (rimabotulinumtoxinB), Dysport® (abobotulinumtoxinA), or Xeomin® (incobotulinumtoxinA); have a skin infection at the planned injection site.
