Dr. Engelman says preventative is legit. “Most certainly! I do micro-injections on patients who are just starting to show the finest expression lines in order to prevent them from ever making the wrinkle." NYC-based board-certified plastic surgeon Norman Rowe, MD, is also a fan. "While Botox has a fundamental use in treating wrinkles that are already formed, it has a role in the prophylactic, or prevention, of wrinkles. So, don't think that you don't need Botox because you don't have wrinkles. If you want to keep that smooth skin, start with Botox before they form."

With the outbreak of World War II, weaponization of botulinum toxin was investigated at Fort Detrick in Maryland. Carl Lamanna and James Duff[42] developed the concentration and crystallization techniques that Edward J. Schantz used to create the first clinical product. When the Army’s Chemical Corps was disbanded, Schantz moved to the Food Research Institute in Wisconsin, where he manufactured toxin for experimental use and generously provided it to the academic community.

The ideal needle to use is a 30G or 31G, half-inch needle. Longer needles are problematic as they encourage deeper injections, which can increase the risk of muscle weakness, and most of the side effects such as neck pain stem from muscle weakness. Perseverative-free normal saline is the only diluent that should be used. There is a case study of a patient who died when onabotulinumtoxinA was mixed with a local anesthetic agent. The pivotal trial established an effective dose using 2 mL/100 units of onabotulinumtoxinA. A fact that is often overlooked is that the mean dose in the trial was 165 units. The patients all received 155 units with a fixed dose, fixed-site injection protocol, and an option of an additional 40 units to follow the pain. This resulted in a mean dose of 165 units, which is the standard that should be used to achieve the efficacy results reviewed above.
Getting Botox takes only a few minutes and no anesthesia is required. Botox is injected with a fine needle into specific muscles with only minor discomfort. It generally takes three to seven days to take full effect and it is best to avoid alcohol at least one week prior to treatment. Aspirin and anti-inflammatory medications should be stopped two weeks before treatment as well in order to reduce bruising.
As with with plastic surgery or any other cosmetic procedure, what you are paying for is an injector who has experience and a proven track record of beautiful results. If you're looking for a precise estimate of what it will cost to achieve your Botox goals, I encourage you to meet with a board-certified plastic surgeon or dermatologist for an initial consultation.

Vials of BOTOX have a holographic film on the vial label that contains the name “Allergan” within horizontal lines of rainbow color. In order to see the hologram, rotate the vial back and forth between your fin gers under a desk lamp or fluorescent light source. (Note: the holographic film on the label is absent in the date/lot area.) If you do not see the lines of rainbow color or the name “Allergan”, do not use the product and contact Allergan for additional information at 1-800-890-4345 from 7:00 AM to 3:00 PM Pacific Time.

The FDA approved such usage in the late 1980s upon the discovery that Botox could stop ailments like blepharospasm (uncontrolled blinking) and strabismus (lazy eye). Doctors have been using Botox for years to successfully treat wrinkles and facial creases. In April 2002, Botox gained FDA approval for treatment of moderate-to-severe frown lines between the eyebrows - called glabellar lines. However, Botox is often used for other areas of the face as well.


"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.
It may be the most well known, but Botox is just one type of neurotoxin on the market. Other, next-level neurotoxins are Dysport, FDA-approved in 2009, and Xeomin, FDA-approved in 2011. “They all originate from the same strain of bacteria, therefore they work essentially in the same way,” explains Z. Paul Lorenc, MD, a board certified aesthetic plastic surgeon in Manhattan. “There are some nuanced differences between the three,” he adds. Xeomin is a purified neurotoxin, also called a “naked molecule,” because it doesn’t contain any extra surface proteins, the way Botox and Dysport do. This “pure” neurotoxin migrates deeper into skin, works faster, and poses less risk of an allergic reaction. “Theoretically, decreasing the protein load also lessens the chance of becoming a non-responder, meaning it lessens the chance that the patient will become immune to the neuromodulator being injected,” Dr. Lorenc says. Dysport tends to spread a little more than Botox, so it’s good for areas that would otherwise need multiple injections. It also kicks in faster than the other two, typically showing effects after two to three days opposed to seven to ten days with Botox, and five to six days with Xeomin. Once you try the different neurotoxins, you might decide you like one brand better than the others.
Botox injections for migraines have been proven to reduce the intensity and duration of migraines for those who suffer. Botox was developed in the 1970s by an ophthalmologist who was looking to develop a treatment for strabismus (crossed eyes). This simple migraine treatment was discovered accidentally when people undergoing plastic surgery also experienced migraine relief. While they don’t work for everyone, Botox injections for migraines offer another way to approach treatment of migraine headaches.

It may be necessary for the patient to have additional procedures, such as the use of filler substances (for example, Restylane, Perlane, Juvederm, Sculptra, or Radiesse) in order to plump up the wrinkles that are now relaxed. Additionally, it may be necessary to have two or three sessions of Botox treatment for deeper wrinkles before results become optimal. The area of the crease between the eyes is a particularly ideal area for Botox use in conjunction with filler as these fixed wrinkles don't always respond optimally to Botox alone. There is some controversy about using filler in that area as it may block veins or arteries and result in loss of blood and a scar to the area. Generally, the smaller particle fillers, such as Restylane or Juvederm Ultra, are best in the area between the eyes for this reason.
Finding an experienced practitioner is particularly important if you’ve never had Botox treatments before as he or she will devise an optimal treatment plan to address your forehead wrinkles. Furthermore, with an experienced, board-certified plastic surgeon you’ll be far less likely to experience any side effects like pain, bruising around the injection site, droopy eyelids, or mistakenly be administered too much Botox, leaving your face looking frozen for the next several months.
When moving a spastic limb through its range of motion, one feels a resistance to movement that increases with the speed at which one moves the limb. This is the definition of spasticity, but other terms such as increased muscle tone, hypertonicity, spastic dystonia, or flexor / extensor spasms are used to describe this resistance. In clinic the term "muscle spasticity" will be used to reduce confusion of terms.
Side effects from cosmetic use generally result from unintended paralysis of facial muscles. These include partial facial paralysis, muscle weakness, and trouble swallowing. Side effects are not limited to direct paralysis however, and can also include headaches, flu-like symptoms, and allergic reactions.[27] Just as cosmetic treatments only last a number of months, paralysis side-effects can have the same durations.[citation needed] At least in some cases, these effects are reported to dissipate in the weeks after treatment.[citation needed] Bruising at the site of injection is not a side effect of the toxin but rather of the mode of administration, and is reported as preventable if the clinician applies pressure to the injection site; when it occurs, it is reported in specific cases to last 7–11 days.[citation needed] When injecting the masseter muscle of the jaw, loss of muscle function can result in a loss or reduction of power to chew solid foods.[27]

Study 3 compared 3 doses of BOTOX with placebo and enrolled 88 patients [BOTOX 360 Units (N=23), BOTOX 180 Units (N=23), BOTOX 90 Units (N=23), and placebo (N=19)] with upper limb spasticity (expanded Ashworth score of at least 2 for elbow flexor tone and at least 3 for wrist flexor tone and/or finger flexor tone) who were at least 6 weeks post -stroke. BOTOX and placebo were injected with EMG guidance into the flexor digitorum profundus, flexor digitorum sublimi s, flexor carpi radialis, flexor carpi ulnaris, and biceps brachii (see Table 27).

Unlike some resurfacing or surgical procedures, after which there is possible pigmentation or scarring, when Botox is done correctly, it can be done on all skin tones. “This is a procedure [and] product that crosses all divides,” says Dr. Matarasso. “Men, women, Caucasian, African-American, Asian, Indian. I don’t think there is a demographic that has not enjoyed the benefit of this product.”
Botox comes as a crystalline substance from the manufacturer, which then has to be reconstituted with saline or another liquid. Practitioners add varying amounts of liquid when reconstituting it. Although there is no right or wrong amount of liquid to add, most physicians add about 2 mL-3 mL (about a half a teaspoon) of liquid to each vial. Some add quite a bit more, which can lead patients to think they are getting more Botox when, in reality, they are getting the same or less amount of Botox than samples reconstituted in a stronger way. It is the total dose of medication, not the volume of liquid, that leads to the desired effect.
On November 23, 2015, Allergan and Pfizer announced their intention to merge in a $160 billion transaction, the largest pharmaceutical deal and the third largest merger in history.[19] On April 5, 2016, after the Obama administration announced its plan to ban tax inversions, Pfizer terminated the acquisition and paid Allergan a $150 million breakup fee.[20]

In 2016, the stock price of Tobira Pharmaceuticals stumbled on the release of the top-line data of the Phase 2b CENTAUR study of CVC therapy in NASH because the clinical trial missed its primary clinical outcome of improvement in NASH resolution without worsening of liver fibrosis. However, CVC therapy achieved its secondary clinical outcome of improvement in liver fibrosis without worsening of NASH resolution. The clinical efficacy of CVC on NASH liver fibrosis is currently being further researched in the ongoing Phase 3 AURORA clinical trial.
As you noted in your question, the effects of Botox don't last forever. For some patients the short term effects of Botox are a ‘good thing,’ as it means that trying Botox is a relatively low risk/low commitment procedure. If you don't like your Botox results, there's not much to worry about: They will fade on their own in a few months. Generally speaking, the results last between three to five months -- but the duration of the Botox effect depends on the individual and on how many Botox units were used.
Of 1242 overactive bladder patients in placebo-controlled clinical studies of BOTOX, 41.4% (n=514) were 65 years of age or older, and 14.7% (n=182) were 75 years of age or older. Adverse reactions of UTI and urinary retention were more common in patients 65 years of age or older in both placebo and BOTOX groups compared to younger patients (see Table 18). Otherwise, there were no overall differences in the safety profile following BOTOX treatment between patients aged 65 years and older compared to youn ger patients in these studies.
Launched in 2002, Practical Neurology is a publication uniquely dedicated to presenting current approaches to patient management, synthesis of emerging research and data, and analysis of industry news with a goal to facilitate practical application and improved clinical practice for all neurologists. Our straightforward articles give neurologists tools they can immediately put into practice.
Unopened vials of BOTOX should be stored in a refrigerator (2° to 8°C) for up to 36 months. Do not use after the expiration d ate on the vial. Administer BOTOX within 24 hours of reconstitution; during this period reconstituted BOTOX should be stored in a refrigerator (2° to 8°C). Reconstituted BOTOX should be clear, colorless, and free of particulate matter.
On July 7, 2015, the company acquired the rights to the late stage CGRP migraine portfolio of Merck & Co, as well as two experimental drugs (MK-1602 and MK-8031) for an upfront payment of $250 million.[12] On August 10, the company acquired Oculeve for $125 million.[13] On August 31, the company acquired Naurex for an upfront payment of $560 million.[14] On October 19, the company acquired AqueSys, developer of ocular implants that reduce intraocular pressure associated with glaucoma, for an initial payment of $300 million.[15] On October 1, the company acquired Kythera Biopharmaceuticals, a company focused on the medical aesthetics market, for $2.1 billion.[16] On November 4 the company announced the acquisition of Northwood Medical Innovation, developer of earFold, a medical device to correct protruding ears.[17] On November 25, 2015, the company announced it would partner with Rugen Therapeutic to develop new therapies for autism spectrum disorder, rabies and obsessive compulsive disorder.[18]
When my babies were little, I never discussed migraine with them. As they grew into preschool and elementary age, I found it necessary to explain it to them.  They had seen me experience migraine symptoms for a long time but understood it as just being sick. We went to a migraine walk where we talked about how others cope like I do, and they heard other stories that were similar to mine. They felt empowered that we had fundraised for a disease that affects millions and that we were fighting it as a family and community. My children want to help. Having ways they can help builds their confidence in their ability to take care of me, as I do them. They know to turn the lights off, get ice and talk quietly. I have taught them how to be self-sufficient. I’m so proud of how they take care of themselves and are willing to take care of others. The qualities that they’re learning and displaying will carry them through life.
Botox stays only where injected, it does not roam through the body. "If I inject it in your face, it's not going to work [or show up in] your toe," says Rowe. "It does not have a systemic effect." However, it may migrate up to 3 cm from where it was injected. But even if some molecules were to go into the bloodstream and travel to distant sites in the body, the cosmetic doses (typically less than 100 units) used are significantly lower than the toxic dose that would be harmful systemically (2,500-3,000 units).

It's safe to say that the mouth is the clearest giveaway of work done too early. Youthful lips tend to have substantial volume and turn up naturally at the corners, meaning the best strategy for flattering them often comes down to a good signature lip color. For women who remain self conscious about the size or symmetry of their lips—think a slightly lopsided appearance, for instance—Botox can be injected into the orbicularis oris muscle along the lip line as an alternative to lip fillers. "When certain individuals smile, the lip flips in and they lose that upper volume," says Dara Liotta, a New York City-based plastic and cosmetic surgeon. "This relaxes the outer layers of the circular muscle around the lips and looks much more natural than filler." Additionally, injections along the jawline—or more specifically, the masseter muscle—have risen in popularity to relieve stress-induced jaw clenching and have also been known to refine the area. "A lot of people hold tension in the jaw area and when you relax that muscle, the chin comes out of the shadow of your lower lip,” explains Liotta. But the best advice of all? Forget about those self-perceived imperfections and smile. You're only in your '20s once.
How long the results from a Botox treatment last depends on the dosage and application. If Botox is too diluted and you don't get the proper units of Botox injected, the results might not last very long at all. If you get Botox for the wrong kind of wrinkles (i.e. static wrinkles) or an improper dose for your anatomy, you might not see much improvement either. In general, if the right amount of Botox is injected by a skilled doctor in the right muscles, Botox results can last 3-4 months.
Safety and effectiveness of BOTOX® have not been established for the treatment of other upper or lower limb muscle groups or for the treatment of spasticity in pediatric patients under age 18 years. BOTOX® has not been shown to improve upper extremity functional abilities, or range of motion at a joint affected by a fixed contracture. Treatment with BOTOX® is not intended to substitute for usual standard of care rehabilitation regimens.
BOTOX is indicated for the treatment of upper limb spasticity in adult patients, to decrease the severity of increased muscle tone in elbow flexors (biceps), wrist flexors (flexor carpi radialis and flexor carpi ulnaris) , finger flexors (flexor digitorum profundus and flexor digitorum sublimis), and thumb flexors (adductor pollicis and flexor pollicis longus).

It's a remarkable arc for a drug that only a few years ago was associated with Hollywood cocktail parties where guests came for Bellinis and left with a forehead full of Botox injections. It highlights the advances that can occur when physicians, seeking new therapies for their patients, explore creative new uses for approved drugs--basically, real-world experiments that take place largely beyond the reach of federal regulators. That, in turn, raises questions about the risks of deploying medicines in ways that have not been fully vetted. But it happens all the time.
In the third study, 25 patients with chronic migraine were injected with 12.5 doses of botox into each trigger point twice, during a period of 3 months. Frequency (main variable), intensity and scales of migraine crises were recorded one month before and one month after the treatment to compare the changes experienced. In addition, side effects were also recorded during the experiment, and they were found to be mild and temporary.

According to the PREEMPT injection paradigm, one injection of 5 units of onabotulinumtoxinA is administered to one site in the procerus muscle. The procerus injection site is approximately midway between the two corrugator injections. In order to confirm the location of the procerus muscle, the patient is asked to furrow the brow, which will activate the belly of the muscle causing the medial furrowing to occur. Once identified, 5 units of onabotulinumtoxinA is injected superficially into the belly of the muscle at a 90° angle to ensure the injection is administered into the procerus rather than the frontalis. Injections placed too superiorly may inadvertently lead to penetration of the frontalis muscle.
Allergan’s Phase 3 hypothesis for securing conditional accelerated approval is to demonstrate that CVC treatment therapeutically initiates and induces improvement in histological hepatic fibrosis without worsening of NASH resolution. Notably, establishing improvement in NASH resolution after CVC therapy in NASH is not a prerequisite for attaining FDA conditional accelerated approval. A Phase 3 interim data readout for FDA Subpart H conditional accelerated approval is anticipated possibly in H1/2019.
Serious and/or immediate hypersensitivity reactions have been reported. These reactions include anaphylaxis, serum sickness, urticaria, soft tissue edema, and dyspnea. If such a reaction occurs, further injection of BOTOX should be discontinued and appropriate medical therapy immediately instituted. One fatal case of anaphylaxis has been reported in which lidocaine was us ed as the diluent, and consequently the causal agent cannot be reliably determined.

The overall cost of  the injection is charged either at a flat rate or per unit. In terms of per unit, the overall cost of the treatment will depend on the total volume or a total number of units used in the procedure. But service charged at a flat rate depends on the area to be treated. The most expensive area is around the underarm for treating hyperhidrosis.


A BOTOX “treatment” consists of 31 injections to the head and neck areas, if adherence to the FDA approved protocol is followed. Except for injection into the procerus, which is in the midline, all others are paired sets of injections on the left and right sides. Muscles included are the frontalis and temporalis areas as well as the occipitalis, upper cervical paraspinals, and trapezii. The amount injected at each of the 31 injection sites is small—5 units of BOTOX in a volume of 0.1 mL normal saline or sterile water. A total of 155 units is are typically used.
When BOTOX was administered intramuscularly to pregnant rats (0.125, 0.25, 0.5, 1, 4, or 8 Units/kg) or rabbits (0.063, 0.125 , 0.25, or 0.5 Units/kg) daily during the period of organogenesis (total of 12 doses in rats, 13 doses in rabbits), reduced fetal body weights and decreased fetal skeletal ossification were observed at the two highest doses in rats and at the highest dose in rabbit s. These doses were also associated with significant maternal toxicity, including abortions, early deliveries, and maternal death. The developmen tal no-effect doses in these studies of 1 Unit/kg in rats and 0.25 Units/kg in rabbits are less than the human dose of 400 Units, based on Units/kg.
In a study to evaluate inadvertent peribladder administration, bladder stones were observed in 1 of 4 mal e monkeys that were injected with a total of 6.8 Units/kg divided into the prostatic urethra and proximal rectum (single administration). No bladder stones were observed in male or female monkeys following injection of up to 36 Units/kg (~12X the highest human bladder dose) directly to the bladder as either single or 4 repeat dose injections or in female rats for single injections up to 100 Units/kg (~33X the highest human bladder dose).

Treatment with BOTOX® and other botulinum toxin products can result in swallowing or breathing difficulties. Patients with pre-existing swallowing or breathing difficulties may be more susceptible to these complications. In most cases, this is a consequence of weakening of muscles in the area of injection that are involved in breathing or oropharyngeal muscles that control swallowing or breathing (see Boxed Warning).

On Wednesday, Saunders said at a conference that Allergan is planning to sell its women's health and infectious disease businesses, putting more attention on Allergan's four "core" businesses, which are eye care, aesthetics, diseases of the central nervous system, and gastrointestinal conditions. Allergan's stock fell on the news, suggesting investors haven't been appeased yet.
The recommended dilution is 200 Units/4 mL or 100 Units/2 mL, with a final concentration of 5 Units per 0.1 mL (see Table 1). The recommended dose for treating chronic migraine is 155 Units ad ministered intramuscularly using a sterile 30-gauge, 0.5 inch needle as 0.1 mL (5 Units) injections per each site. Injections should be divided across 7 specific head/neck muscle areas as specified in the diagrams and Table 2 below. A one inch needle may be needed in the neck region for patients with thick neck muscles. With the exception of the procerus muscle, which should be injected at one site (midline), all muscles should be injected bilaterally with half the number of injection sites administered to the left, and half to the right side of the head and neck. The recommended re-treatment schedule is every 12 weeks.
The American Migraine Foundation recently launched the American Registry for Migraine Research, or ARMR. ARMR collects information and biospecimens from patients living with migraine and other disorders that cause head pain. ARMR will be used to help health care providers and scientists better understand the causes, characteristics, and management of migraine and other headache types. Anonymized ARMR data will be made available to researchers who apply for access, enhancing the efficiency by which headache research can be conducted. Dr. Todd Schwedt, Professor of Neurology at the Mayo Clinic in Scottsdale, Arizona, and co-principal investigator of ARMR, expands on the registry.

The cost of Botox injections varies widely, with most clinics in the United States charging between $9 and $20 per unit. The variation in cost can be influenced by a number of factors, including the location of the clinic or medspa, and the reputation and expertise of the injector. For example, board-certified plastic surgeons who specialize in administering Botox and dermal fillers are likely to charge more because they generally guarantee better results. That is not to say, however, that injectors charging $10 per unit aren’t capable of delivering excellent results as well, but there is far less risk of any complications arising when you choose an injector who has been board-certified. It is always the smartest, safest way to proceed with any cosmetic enhancement.
That said, there are a few things I'd make sure everyone knows before trying it. For one thing, it can be pretty painful. I have a pretty high pain tolerance, but getting 30 to 40 shots every three months is pretty rough — it feels a bit like getting tattooed with a bee's stinger, but once the needle is out of your skin, the pain goes away, and if it works for you, it's worth it. It's also important to know that it can take some time to work. The first treatment barely worked at all for me, and the second round took a few weeks. If you're going to try it out, be patient.

I’ve had migraines since I was 12, but in 2015 my attacks got much worse. Without migraine-specific painkillers, my migraines make me queasy and tired, forcing me to go to bed with a freezing wet towel on my head. For the last two years, I’ve tried different medications, switched birth control pills, made lifestyle changes (less stress, more swimming, no alcohol) — to little avail. My migraines would improve for a while, but then they came back, worse than ever. Then this year, I finally discovered a treatment that works — Botox.

Botulinum toxin has been investigated for use in patients with blepharospasm in several studies. In an open label, historical ly controlled study, 27 patients with essential blepharospasm were injected with 2 Units of BOTOX at each of six sites on each side. Twenty-five of the 27 patients treated with botulinum toxin reported improvement within 48 hours. One patient was controlled with a higher dosage at 13 weeks post initial injection and one patient reported mild improvement but remained functionally impaired.
The seven toxin types (A-G) have different tertiary structures and sequence differences.[35][36] While the different toxin types all target members of the SNARE family, different toxin types target different SNARE family members.[34] The A, B, and E serotypes cause human botulism, with the activities of types A and B enduring longest in vivo (from several weeks to months).[35]
