"We were very skeptical," says Edwin Chapman, a professor of neuroscience at the University of Wisconsin--Madison, after reading Caleo's study. But in August 2016, Chapman and his graduate student Ewa Bomba-Warczak published a study in the journal Cell Reports showing similar spreading effects in animal cells in the lab. For Chapman, it explained what he was hearing anecdotally from doctors: that Botox might be influencing the central nervous system and not just the area where it's being injected.
The primary release procedure for BOTOX uses a cell-based potency assay to determine the potency relative to a reference standard. The assay is specific to Allergan's products BOTOX and BOTOX Cosmetic. One Unit of BOTOX corresponds to the calculated median intraperitoneal lethal dose (LD50) in mice. Due to specific details of this assay such as the vehicle, dilution scheme, and laboratory protocols, Units of biological activity of BOTOX cannot be compared to nor converted into Units of any other botulinum toxin or any toxin assessed with any other specific assay method. The specific activity of BOTOX is approximately 20 Units/nanogram of neurotoxin protein complex.
Other side effects of BOTOX® and BOTOX® Cosmetic include: dry mouth, discomfort or pain at injection site, tiredness, headache, neck pain, eye problems: double vision, blurred vision, decreased eyesight, drooping eyelids, swelling of eyelids, dry eyes, and drooping eyebrows. In people being treated for urinary incontinence other side effects include: urinary tract infection, painful urination, and/or inability to empty your bladder on your own. If you have difficulty fully emptying your bladder after receiving BOTOX®, you may need to use disposable self-catheters to empty your bladder up to a few times each day until your bladder is able to start emptying again.

There are numerous areas where Botox may be used, including the forehead, crow's feet, gummy smile, chin, neck, and other areas of the body. Many of these are under investigation at this time for approval by the FDA. Additionally, topical forms of botulinum toxin (Revance) are under study at present. With time, these will likely come to market and be absorbed into the body of treatments for which Botox is used.
“Botox is a completely cosmetic procedure, so if and when someone ‘needs’ it is a purely personal decision,” Shah says. “Some people are not bothered by developing fine lines and wrinkles. For those who are, I generally advise starting treatments just when they start to see the lines develop, or when the wrinkles linger even after the movement has stopped.”
Most insurance providers now recognize BOTOX as treatment for migraines. Some have specific criteria that patients must meet, or require documentation that you have gone through other treatment protocols before trying BOTOX. It can take several weeks to receive authorization to begin treatment. Check with your insurance provider to make sure you fulfill their requirements, and to begin the approval process.
Richard Clark, a plastic surgeon from Sacramento (CA), was the first to document a cosmetic use for botulinum toxin. He treated forehead asymmetry caused by left sided forehead nerve paralysis that occurred during a cosmetic facelift. Since the injured nerve could possibly regenerate by 24 months, a two-year waiting period was necessary before definitive surgical treatment could be done. Clark realized that botulinum toxin, which had been previously used only for cross eyed babies and facial tics, could also be injected to smooth the wrinkles of the right forehead to match her paralyzed left. He received FDA approval for this cosmetic application of the toxin and successfully treated the person and published the case study in 1989.
Lalvani previously worked in organizations dedicated to diabetes, breast cancer and kidney disease, but strongly identifies with our community because she is living with migraine. She recalls first getting what she thought were terribly debilitating headaches when she was 18. “I had no idea what a migraine was,” she said, “and I never saw anyone around me have a migraine, so I had no idea what I was dealing with, and no one else around me knew what I was dealing with.” Lalvani is excited to see the progress that’s been made recently in migraine care and the tremendous effort that AMF has put forth in helping advance research to produce therapies at a faster rate. As you know, the mission for AMF is to drive and support impactful research that translates into treatment advances as well as mobilize the community for patient support and advocacy.
In many children, there are a few muscle groups that can have very active spasticity. A more focal approach to these muscles would be better than a widespread approach. In this case a doctor may advise a nerve block to interrupt the signal to the muscle that is spastic. Once the signal that is carried to the muscle by the nerve is interrupted, the spasticity will decrease.
With small children, I find that being prepared allows us to function better. My family food preps for the week with fruits, veggies and snack-size portions. I keep the snacks on a shelf that my children can easily reach, so they can choose a healthy option if they’re hungry and I’m unable to get up. Meals are well-thought-out and prepared ahead of time, in case of a migraine attack. I always have a back-up plan for my children. I have alternative arrangements for them after school if I am unable to care for them or myself. I also have activities planned. I keep crafts around that occupy my children’s time but also keep sound and stress to a minimum. We color, build Legos and play with Play-Doh all while sitting in rooms with strategically placed lights and brightness. I save screen time for when I need a few moments of quiet. We keep a routine and schedule, but also stay flexible. A schedule allows my family to know what to expect for our days and evenings. My children are able to continue their day if I have a migraine attack because they know what needs to be done and in what order. We have strict bedtimes that allow my children’s brains to grow and mine to recover. Along with this, I have taught them that moms don’t always feel well, and we may need to adjust the schedule from time to time to accommodate my migraine. I keep medication that can fight a migraine attack with me for use on the go and safely at home. I see a neurologist on a regular basis who helps me manage my migraine symptoms and medication.
In 2010, Allergan pleaded guilty and agreed to pay $600 million to resolve allegations that it unlawfully promoted Botox for conditions--including headaches, pain, spasticity and juvenile cerebral palsy--that at the time were not approved by the FDA. In one of the complaints, prosecutors said that Allergan "illegally, vigorously and without any thought to the possible negative health effects to which it subjected patients, promoted off-label uses of Botox." The U.S. Department of Justice also argued that Allergan exploited on-label uses for cervical dystonia--a disorder characterized by extreme neck-muscle contractions--to "grow off-label pain and headache sales." Prosecutors also argued that Allergan paid doctors to give presentations and trainings to other physicians about Botox uses that at the time were off-label.
"Botox is a toxin that is extracted from a certain bacteria. It's been used for a couple of hundred years in medicine. It was first used in neurological conditions rather than cosmetic ones. It was first approved to treat spasms of the face and eye muscles. Only later was it discovered coincidentally that it could world for cosmetic purposes, like wrinkles," he says.
After Hoffman’s husband was diagnosed with Parkinson’s at 55, his health insurance decided to stop paying for the drug he had taken successfully unless he tried cheaper alternatives. She appealed on behalf of her husband and was eventually able to get approval for the drug, which would have cost them $8,000 a year otherwise. “I felt terrible and I had to fight and it took a long time,” Hoffman tells The Verge. “It caused a lot of anxiety and a lot of these patients don’t have a law professor wife to fight for them.”
BOTOX® treats the symptoms of severe underarm sweating when topical medicines do not work well enough in people 18 years and older. It is not known whether BOTOX® is safe or effective for severe sweating anywhere other than your armpits. BOTOX® treatments temporarily block the chemical signals from the nerves that stimulate the sweat glands, resulting in reduced sweating.
