Duration of response was calculated as the number of days between injection and the date of the first visit at which patients returned to 3 or 4 on the HDSS scale. The median duration of response following the first treatment in BOTOX treated patients with either dose was 201 days. Among those who received a second BOTOX injection, the median duration of response was similar to that observed after the first treatment.
* LS mean change, treatment difference and p-value are based on an analysis using an ANCOVA model with baseline weekly endpoint as covariate and treatment group, etiology at study entry (spinal cord injury or multiple sclerosis), concurrent anticholinergic therapy at screening, and investigator as factors. LOCF values were used to analyze the primary efficacy variable.
Botulinum toxin is used to treat certain eye disorders such as crossed eyes (strabismus) and uncontrolled blinking (blepharospasm), to treat muscle stiffness/spasms or movement disorders (such as cervical dystonia, torticollis), and to reduce the cosmetic appearance of wrinkles. It is also used to prevent headaches in people with very frequent migraines. Botulinum toxin relaxes muscle by blocking the release of a chemical called acetylcholine.
Migraine with visual aura involves visual effects that usually precede the headache and last at least 5 minutes. The visual aura is usually an expanding blinding spot or visual scintillations (shimmering objects in the visual field). Other aura features include reversible symptoms of speech and language difficulty such as word-finding problems and aphasia (inability to express words or comprehend words), sensory phenomena such as tingling in the extremities extending to the face, motor effects such as weakness, and brainstem problems such as unsteadiness and features of cranial nerve dysfunction. These aura symptoms usually last 5 to 60 minutes, can precede or start during the headache, and can also occur without a headache.
A double-blind, placebo-controlled study enrolled patients who had extended histories of receiving and tolerating BOTOX injections, with prior individualized adjustment of dose. The mean BOTOX dose administered to patients in this study was 236 Units (25th to 75th percentile range of 198 Units to 300 Units). The BOTOX dose was divided among the affected muscles [see Clinical Studies].
Can you use Botox under your eyes? Botox is often used to treat lines and wrinkles around the eyes and mouth. Can it also reduce dark circles or bags under the eyes? Using Botox under the eyes is not approved in the U.S. and researchers are unsure how well it may work and what side effects may occur. Here, learn about the procedure and its alternatives. Read now
Dr. Schwedt believes ARMR offers hope for patients living with migraine. “ARMR data could lead to breakthroughs in the field,” he says. One hope for ARMR is that it will contribute to the ability for health care providers to use precision medicine to treat their patients. Clinical trials show which migraine therapies are overall effective for groups of people with migraine; however, health care providers are still working to understand which specific therapy is ideal for a particular patient. “One of the challenges we have in this field right now is being able to determine which exact therapy is going to be best for which patient,” Dr. Schwedt says. “For example, we might know that about 50% of patients will benefit from a specific migraine preventive therapy, but we don’t know in advance which 50% that is. I believe the data we’re collecting in ARMR is going to help us get to the stage where we can practice precision medicine, knowing which therapy is most likely to help an individual patient prior to the patient starting that therapy.”
"In the majority of these cases, it's the doctors at the front line who start using Botox off-label, and then we see the treatment of things we never expected the toxin to work for," says Min Dong, a researcher at Harvard Medical School who studies botulinum toxins in the lab and has no financial ties to Allergan. "I meet with physicians who are using the toxin everywhere--for diseases you would never know about."
In the mid-1990s, people who received BOTOX for other conditions reported improvement in their chronic migraine pain. A two-phase study was conducted, treating patients who averaged 20 headache days a month. They received BOTOX injections every twelve weeks for 56 weeks. At the end of that period, 70% of the patients had fewer than half the number of headaches they had before treatment. The FDA officially approved BOTOX to treat chronic migraine in October of 2010. Since then, more than 100,000 patients have been treated.
BTX-A is now a common treatment for muscles affected by the upper motor neuron syndrome (UMNS), such as cerebral palsy, for muscles with an impaired ability to effectively lengthen. Muscles affected by UMNS frequently are limited by weakness, loss of reciprocal inhibition, decreased movement control and hypertonicity (including spasticity). In January 2014, Botulinum toxin was approved by UK's Medicines and Healthcare Products Regulatory Agency (MHRA) for the treatment of ankle disability due to lower limb spasticity associated with stroke in adults. Joint motion may be restricted by severe muscle imbalance related to the syndrome, when some muscles are markedly hypertonic, and lack effective active lengthening. Injecting an overactive muscle to decrease its level of contraction can allow improved reciprocal motion, so improved ability to move and exercise.
“ARMR is a longitudinal study. We’re collecting data over time, which will allow us to study changes in headache patterns, health care resource utilization, diagnostic and management strategies, development of co-morbidities and responses to therapies,” Dr. Schwedt says. The registry is comprised of multiple components: The first component is an online platform in which participants fill out a baseline and follow-up questionnaires and clinicians enter the participants’ headache diagnoses. There is also an ARMR headache diary mobile app in which participants share daily information about their migraine attacks, their level of function and their treatment, if any. The third component is a blood sample, which is processed and stored in the ARMR biobank and will be used for genetic analyses. Brain imaging data are collected in the ARMR Neuroimaging Repository, and electronic health record data are pulled and confidentially entered into a centralized ARMR database. “Oftentimes, research is done in silos,” Dr. Schwedt says. “So a group at one institution is doing their own work, collecting their own data, doing their own analysis. And a group at another institution is doing their own work. That isn’t the most efficient way to move forward in the field. We believe creating and sharing data from this large and comprehensive study is really going to improve the efficiency of research in the field.”
Botox only lasts three to six months—and yet what's less commonly discussed is this: Facial muscles naturally weaken over time and going overboard in a certain area could have unwanted consequences. "If you do too much Botox on your forehead for many, many years, the muscles will get weaker and flatter," cautions Wexler, adding that the skin can also appear thinner and looser. Moreover, as your muscles become weaker, they can start to recruit surrounding muscles when you make facial expressions. "If one stops using their forehead muscles, they may start squinting using their nose and have wrinkles along the side of their nose," she explains. Translation: You need even more Botox for the newly recruited muscles, says Wexler. To avoid these kind of missteps, researching a doctor diligently is essential, as is approaching injectables conservatively, and asking questions about how the treatment will be tailored to your needs.
There's been a pivotal shift in how women in their 20s look at their faces. And while the reasons are arguably as multi-faceted as this new generation itself, many would agree on one thing: The impact of social media, from selfies to YouTube videos to meticulously crafted Snapchat and Insta Stories, combined with endlessly retouched photographs in magazines and ad campaigns, can not be underestimated. From the constant stream of supernaturally smooth jawlines and chiseled cheekbones to celebrity plastic surgeons posting before-and-after images of their work, the age of 24/7 self-documentation has spurred a novel set of beauty ideals—and, with it, a dramatic increase in cosmetic procedures. For 20-somethings, there's no treatment more popular—or controversial—than Botox. Need proof? According to the American Society of Plastic Surgeons, botulinum toxin procedures have increased 28 percent since 2010 amongst 20 to 29-year-olds.
In rare cases, Botox toxin can spread to areas beyond the injection site. If this happens, you may experience muscle weakness, vision changes, difficulty swallowing, and drooping eyelids. To reduce your risk of serious side effects and complications, always make sure Botox is prescribed and administered by a trained healthcare professional who has experience in using Botox.

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.
