There are many physicians who encourage their patients to either work the area several times during the next several days or, alternatively, to not use the affected muscles during the next several days. Many practitioners do not tell the patients to do anything in particular other than to avoid strenuous activity for several hours afterward because of an increased risk of bruising.
I had no idea my health insurance could take Botox away from me. I checked Cigna’s policy and found out that in order to continue receiving Botox coverage after one year, I need to get at least seven fewer migraine days — or at least 100 fewer migraine hours — per month compared to pre-Botox treatments. (I keep a diary to record when I have migraines.) Worse still, if I were to change my job — and therefore change my health insurance — my new insurance could ask me to run through the cheap medication gauntlet again before covering Botox.
It is not known whether BOTOX® is safe or effective to treat increased stiffness in upper limb muscles other than those in the elbow, wrist, fingers, and thumb, or in lower limb muscles other than those in the ankle and toes. BOTOX® has not been shown to help people perform task-specific functions with their upper limbs or increase movement in joints that are permanently fixed in position by stiff muscles. Treatment with BOTOX® is not meant to replace existing physical therapy or other rehabilitation that may have been prescribed.

Injections: They're a popular topic and yet still shrouded in mystery and a veritable amount of secrecy. Most of us venture to a consultation or decide against them without actually knowing much information—how much they cost, what to expect during an appointment, or what the results will be. Because we're not willing to openly and freely discuss it (or have been taught not to), more often than not these conversations occur through a series of unanswered questions. Like sexual education, relying on abstinence is never going to be enough. We want to feel confident, look good, and make our own choices, and as such, that often leads to investing in modern skincare techniques.
Above all, I try to be gentle with myself and my children. It’s easier said than done.  Mom guilt and migraine guilt weigh heavy on my heart, and I continue to remind myself that I’m doing my best. I give myself a break as I do with my children when they’re having a bad day. I’m patient with them and try to give myself the same respect.  As a mom, it seems like my job is never done and that I can always do better. The reality is, no one is perfect, and we all have our flaws. We don’t expect our children to be perfect, and we should not expect ourselves to be. We do what we can when we can and take each day as it comes. I find joy in the smallest things and find that being grateful and mindful remind me off all the blessings I have, despite my unpredictable and chronic migraine attacks.

In study 2, 320 adults with bilateral axillary primary hyperhidrosis were randomized to receive either 50 Units of BOTOX (n=2 42) or placebo (n=78). Treatment responders were defined as subjects showing at least a 50% reduction from baseline in axillary sweating measured by gravimetric measurement at 4 weeks. At week 4 post-injection, the percentages of responders were 91% (219/242) in the BOTOX group and 36% (28/78) in the placebo group, p<0.001. The difference in percentage of responders between BOTOX and placebo was 55% (95% CI=43.3, 65.9).

Botox is a brand name of a toxin produced by the bacterium Clostridium botulinum. There are other brand names for botulinum, such as Xeomin. In large amounts, this toxin can cause botulism, which you probably associate with food poisoning. Despite the fact that one of the most serious complications of botulism is paralysis, scientists have discovered a way to use it to human advantage. Small, diluted amounts can be directly injected into specific muscles causing controlled weakening of the muscles.
Botox (also known as Vistabel outside the U.S. and the U.K.) is an injection that temporarily relaxes facial muscles to reduce the appearance of fine lines and wrinkles, as well as prevent new lines from forming. Common injection sites include the forehead, the area between the eyebrows, the corners of the eyes, and the sides of the chin. Botox can also be used for a wide variety of other conditions, including migraines, excessive sweating, and psoriasis. LEARN MORE ›
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.

As with all therapeutic proteins, there is a potential for immunogenicity. The detection of antibody formation is highly dependent on the sensitivity and specificity of the assay. Additionally, the observed incidence of antibody (including neutralizing antibo dy) positivity in an assay may be influenced by several factors including assay methodology, sample handling, timing of sample collection, concomitant medications, and underlying disease. For these reasons, comparison of the incidence of antibodies to onabotulinumtoxinA in the studies described below with the incidence of antibodies in other studies or to other products may be misleading.


In clinical trials, 30.6% of patients (33/108) who were not using clean intermittent catheterization (CIC) prior to injection, required catheterization for urinary retention following treatment with BOTOX® 200 Units as compared to 6.7% of patients (7/104) treated with placebo. The median duration of postinjection catheterization for these patients treated with BOTOX® 200 Units (n = 33) was 289 days (minimum 1 day to maximum 530 days) as compared to a median duration of 358 days (minimum 2 days to maximum 379 days) for patients receiving placebo (n = 7).
Results will be evident within three to 10 days. Photographs may be taken before the procedure so that patients can check their results themselves rather than relying on their memory. It is surprising to see how many people do not recall how they looked before the procedure and are amazed at the difference when shown a picture. Prior to having the procedure done, the patient should realize that Botox does not actually erase lines but relaxes them. What this means is that deeper lines will become somewhat less deep and superficial lines will nearly disappear. This can be likened to the act of steaming a garment's wrinkles rather than ironing them.
In a recent Facebook Live, our new director Nim Lalvani introduced herself to the migraine community. If you missed our Facebook Live, watch the recording below or read on to learn more about Lalvani’s personal connection to migraine and her plans for the Foundation. [embed]https://www.facebook.com/americanmigrainefoundation/videos/290329171553466/[/embed] In the short time that Lalvani has worked at AMF, she’s been impressed by the strong and vibrant community of doctors, patients and advocates. Lalvani’s background is in public health, and she has dedicated her career to patient engagement. She has worked in the nonprofit and patient advocacy spaces for more than 12 years, helping patients at both the national and international level. “I've specifically focused my career on designing and providing the rights tools and resources for patients at the times that they need it most,” she shared, adding that her goal is to amplify patients’ voices in research and therapeutic development.
These injection sites have been carefully chosen to treat specific nerve endings that are sending pain signals. BOTOX for migraines has proven to be a highly-effective treatment for people who are living with the painful, debilitating symptoms of chronic migraines. BOTOX will be carefully and correctly injected into muscles just beneath the skin. The procedure is not particularly painful, with a sensation of pinpricks.
In some practices, the cost of the actual product determines the price, but in others, "The cost of the treatment is based on the skill set, not the product," says Day. In other words, seeing a trained aesthetic physician, who has the time and technique to give you tailored, micro injections, might actually be more costly than larger, more formulaic doses.
I don’t know what’s harder, being a mom or living with migraine. Having both can be overwhelming. Over the years, as a stay-at-home mom of two and chronic migraine fighter, I have learned to adapt my life and my children’s lives to migraine. I alter my family’s schedule around my children’s naps, meals and moods, while also keeping in mind my migraine attacks, sensitivities, triggers and abilities.
I tell my patients that it is not the total price that is important, but how many units are used. For instance, if a patient goes to a spa and pays $150 per area, that may sound like a great deal. However, when the patient ask how long the treatment is supposed to last, the spa responds "2 months". I have seen that many of those less expensive treatments often consist of around 10 units (and therefore carrying a "non-deal" $15 cost per unit!). So, what initially looks like a great bargain, is in fact just a treatment with an inadequate amount of Botox. Always ask your injector how many units they are using, so you can determine what price/unit you are getting. Experienced injectors know that there is no such thing as a standard amount of units, as everyone's facial anatomy and muscular strengths are variable, even from one side of the face to the other.

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).
Alternatively, bruising could occur, though is less likely, says Rowe, especially in the hands of an experienced doctor. While he says it's "dumb luck" whether or not one bruises from an injection, he also notes that good technique helps reduce the chances. Sobel says that "if you inject [the needle with Botox] too deep, very often you can hit a blood vessel and bruise." What you do after the injection can also make a difference: Take care not to rub or massage the treated areas, as this can cause the toxin to migrate.

Postmarketing reports indicate that the effects of BOTOX® Cosmetic and all botulinum toxin products may spread from the area of injection to produce symptoms consistent with botulinum toxin effects. These may include asthenia, generalized muscle weakness, diplopia, ptosis, dysphagia, dysphonia, dysarthria, urinary incontinence and breathing difficulties. These symptoms have been reported hours to weeks after injection. Swallowing and breathing difficulties can be life threatening and there have been reports of death. The risk of symptoms is probably greatest in children treated for spasticity but symptoms can also occur in adults treated for spasticity and other conditions, particularly in those patients who have an underlying condition that would predispose them to these symptoms. In unapproved uses, including spasticity in children, and in approved indications, cases of spread of effect have been reported at doses comparable to those used to treat cervical dystonia and spasticity and at lower doses.

The potency Units of BOTOX (onabotulinumtoxinA) for injection are specific to the preparation and assay method utilized. They are not interchangeable with other preparations of botulinum toxin products and, therefore, units of biological activity of BOTOX cannot be compared to nor converted into units of any other botulinum toxin products assessed with any other specific assay method [see WARNINGS AND PRECAUTIONS and DESCRIPTION] .
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."

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.

This product contains albumin, a derivative of human blood. Based on effective donor screening and product manufacturing processes, it carries an extremely remote risk for transmission of viral diseases and variant Creutzfeldt-Jakob disease (vCJD). There is a theoretical risk for transmission of Creutzfeldt-Jakob disease (CJD), but if that risk actually exists, the risk of transmission would also be considered extremely remote. No cases of transmission of viral diseases, CJD, or vCJD have ever been identified for licensed albumin or albumin contained in other licensed products.

The efficacy and safety of BOTOX for the treatment of primary axillary hyperhidrosis were evaluated in two randomized, multi center, double-blind, placebo-controlled studies. Study 1 included adult patients with persistent primary axillary hyperhidrosis who scored 3 or 4 on a Hyperhidrosis Disease Severity Scale (HDSS) and who produced at least 50 mg of sweat in each axilla at res t over 5 minutes. HDSS is a 4-point scale with 1 = “underarm sweating is never noticeable and never interferes with my daily activities”; to 4 = “underarm sweating is intolerable and always interferes with my daily activities”. A total of 322 patients were randomized in a 1:1:1 ratio to treatment in both axillae with either 50 Units of BOTOX, 75 Units of BOTOX, or placebo. Patients were evaluated at 4-week intervals. Patients who responded to the first injection were re-injected when they reported a re-increase in HDSS score to 3 or 4 and produced at least 50 mg sweat in each axilla by gravimetric measurement, but no sooner than 8 we eks after the initial injection.
Botox must be used only under a doctor's care. It's important that injections be placed precisely in order to avoid side effects. Botox therapy can be dangerous if it's administered incorrectly. Ask for a referral from your primary care doctor or look for a doctor who specializes in your condition and who has experience in administering Botox treatments.
"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."

The one side effect that we most commonly see with Botox for migraine, ironically, is increased headache pain in the days immediately following the injections. Interestingly, some patients have the opposite effect, noticing immediate pain relief. That may be due to an acupuncture-like response, where poking needles into unhappy muscles actually makes them feel better.

The primary efficacy variable was wrist flexors muscle tone at week 6, as measured by the Ashworth score. The Ashworth Scale is a 5-point scale with grades of 0 [no increase in muscle tone] to 4 [limb rigid in flexion or extension]. It is a clinical measure of the force required to move an extremity around a joint, with a reduction in score clinically representing a reduction in the force need ed to move a joint (i.e., improvement in spasticity).

Botulinum toxin exerts its effect by cleaving key proteins required for nerve activation. First, the toxin binds specifically to nerves which use the neurotransmitter acetylcholine. Once bound to the nerve terminal, the neuron takes up the toxin into a vesicle. As the vesicle moves farther into the cell, it acidifies, activating a portion of the toxin which triggers it to push across the vesicle membrane and into the cell cytoplasm.[1] Once inside the cytoplasm, the toxin cleaves SNARE proteins preventing the cell from releasing vesicles of neurotransmitter. This stops nerve signaling, leading to paralysis.[1]
In a double-blind, placebo-controlled, parallel group study in adult patients with detrusor overactivity associated with a neurologic condition and restrictive lung disease of neuromuscular etiology [defined as FVC 50-80% of predicted value in patients with spinal cord injury between C5 and C8, or MS] the event rate in change of Forced Vital Capacity ≥15% or ≥20% was generally greater in patients treated with BOTOX than in patients treated with placebo (see Table 6).
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.
In 1986, Scott's micromanufacturer and distributor of Botox was no longer able to supply the drug because of an inability to obtain product liability insurance. Patients became desperate, as supplies of Botox were gradually consumed, forcing him to abandon patients who would have been due for their next injection. For a period of four months, American blepharospasm patients had to arrange to have their injections performed by participating doctors at Canadian eye centers until the liability issues could be resolved.[48]
In general, you’ll find that Botox costs about $10-$20 per unit. While some offices and clinics charge a flat rate, depending on the area that they’re working on, you’ll more often find that you are charged based on how many units of Botox are used to achieve the results you’re looking for. You need around 20 units to treat your forehead and 5-6 units to treat crows feet, making Botox an affordable alternative to going under the knife.

What are Botox costs and benefits? Hands down, one of the most exciting cosmetic procedures in dermatology is Botox. It’s been over a decade that this miracle injectable has been approved for cosmetic use and the effects have been amazing. With one injection, Botox has the ability to iron out wrinkles and even prevent new ones from forming. Botox is completely safe and the perfect alternative to plastic surgery. Botox has even been shown to lift moods. A recent study showed that Botox had the ability to improve symptoms of depression when injected in the area in between and directly above the eyebrows. Other areas that can be treated with Botox are the crow’s feet, the upper forehead and around the hairline, to give the entire top half of the face a lift. Plus even more good news for Botox users! A new study shows that Botox injections not only get rid of wrinkles, but also make the overlying skin look and feel younger. So that means the overall appearance of your skin will look rejuvenated thanks to Botox injections. While the cost of Botox injections is certainly not cheap, it’s a sure thing and will produce real results that you can be happy with .


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.

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.
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 important to set up reasonable expectations for your Botox experience. “Botox does not get rid of all wrinkles on your face—it gets rid of wrinkles made from expressions,” Dr. Waibel explains. “It improves the appearance of these wrinkles by relaxing the muscles. It does not get rid of what we call static wrinkles—the ones that are seen at rest when looking in the mirror.” If those wrinkles bother you, talk to your dermatologist about the laser treatments that can help smooth them out. Find out the 13 craziest requests plastic surgeons have received.
Significant improvements compared to placebo in the primary efficacy variable of change from baseline in daily frequency of incontinence episodes were observed for BOTOX® (100 Units) at the primary efficacy time point at week 6. Increases in maximum cystometric capacity and reductions in maximum detrusor pressure during the first involuntary detrusor contraction were also observed. These primary and secondary endpoints are shown in Table 23.

Do not inject into blood vessels. Introduction of these products into the vasculature may lead to embolization, occlusion of the vessels, ischemia, or infarction. Take extra care when injecting soft-tissue fillers; for example, inject the product slowly and apply the least amount of pressure necessary. Rare, but serious, adverse events associated with the intravascular injection of soft-tissue fillers in the face have been reported and include temporary or permanent vision impairment, blindness, cerebral ischemia or cerebral hemorrhage leading to stroke, skin necrosis, and damage to underlying facial structures. Immediately stop the injection if a patient exhibits any of the following symptoms: changes in vision, signs of a stroke, blanching of the skin, unusual pain during or shortly after the procedure. Patients should receive prompt medical attention and, possibly, evaluation by an appropriate healthcare professional specialist should an intravascular injection occur

Exploratory analyses of this study suggested that the majority of patients who had shown a beneficial response by week 6 had returned to their baseline status by 3 months after treatment. Exploratory analyses of subsets by patient sex and age suggest that both sexes receive benefit, although female patients may receive somewhat greater amounts than male patients. There is a consistent trea tmentassociated effect between subsets greater than and less than age 65. There were too few non-Caucasian patients enrolled to draw any conclusions regarding relative efficacy in racial subsets.
The safe and effective use of BOTOX depends upon proper storage of the product, selection of the correct dose, and proper reconstitution and administration techniques. An understanding of standard electromyographic techniques is also required for treatment of strabismus, upper or lower limb spasticity, and may be useful for the treatment of cervical dystonia. Physicians administering BOTOX must understand the relevant neuromuscular and structural anatomy of the area involved and any alterations to the anatomy due to prior surgical procedures and disease, especially when injecting near the lungs.
The needle should be inserted approximately 2 mm into the detrusor, and 30 injections of 1 mL (~6.7 Units) each (total volume of 30 mL) should be spaced approximately 1 cm apart (see Figure 1). For the final injection, approximately 1 mL of sterile normal s aline should be injected so that the remaining BOTOX in the needle is delivered to the bladder. After the injections are given, the saline used for bladder wall visualization should be drained. The patient should be observed for at least 30 minutes post -injection.
The needle should be inserted approximately 2 mm into the detrusor, and 20 injections of 0.5 mL each (total volume of 10 mL) should be spaced approximately 1 cm apart (see Figure 1). For the final injection, approximately 1 mL of sterile normal saline should be injected so that the remaining BOTOX in the needle is delivered to the bladder. After the injections are given, patients shou ld demonstrate their ability to void prior to leaving the clinic. The patient should be obser ved for at least 30 minutes post-injection and until a spontaneous void has occurred.
Around The Eyes – It is common to see wrinkles and creases around your eyes, as the muscles around your eyes are constantly contracting when you talk or smile. The crow’s feet that have formed on the corner of your eyes can be effectively reduced with the help of Botox.  Moreover, a Botox can help diminish the fine creases that have formed under your eyes.
Each patient has their own goals for treatment of muscle spasticity made in our clinic. These goals can include decreasing pain from muscle spasms. This can be done by reducing both how often and how intense the spasms are. It can also be done by increasing the range of motion of joints to allow improved function. Improvement of range of motion can help to:
Investors have been unhappy with Allergan's stock performance over the last year, and some have expressed interest in seeing the pharma company explore splitting up. On Wednesday, Allergan announced it plans to sell its women's health and infectious disease businesses. The news sent Allergan's stock down 2%, suggesting the move didn't go as far as some would like.
One glaring example took place over the weekend, when someone on Twitter (TWTR) posted a photograph of an injured police officer, with a caption that he’d been “brutalized” by the migrant caravan on its way to the United States. “These pictures do not capture police officers who were brutalized by members of the immigrant caravan making its way toward the U.S. in October 2018,” Snopes explained.
BOTOX is administered about every three months, and must be injected at the site of each nerve trigger, relaxing the surrounding muscles so that they won’t compress the nerve and trigger a migraine. It is a potent drug, and we only recommend using it if other preventative treatment options haven’t helped you. It is generally only administered to patients who have at least 14 headaches a month, or don’t respond to other treatments.
Two double-blind, placebo-controlled, randomized, multi-center clinical studies were conducted in patients with urinary incontinence due to detrusor overactivity associated with a neurologic condition who were either spontaneously voiding or using catheterization (Studies NDO-1 and NDO-2). A total of 691 spinal cord injury (T1 or below) or multiple sclerosis patients, who had an inadequate response to or were intolerant of at least one anticholinergic medication, were enrolled. These patients were randomized to receive either 200 Units of BOTOX (n=227), 300 Units of BOTOX (n=223), or placebo (n=241).
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.
Botox® neurotoxin treatment helps control the symptoms of severe underarm sweating when topical medicines do not work well enough by temporarily blocking the chemical signals from the nerves that stimulate the sweat glands. When the sweat glands don’t receive chemical signals, the severe sweating stops. Botox® injections are expected to temporarily stop the production of excessive sweat in the treated areas only. Sweat continues to be produced elsewhere.
Since then, several randomized control trials have shown botulinum toxin type A to improve headache symptoms and quality of life when used prophylactically for patients with chronic migraine[88] who exhibit headache characteristics consistent with: pressure perceived from outside source, shorter total duration of chronic migraines (<30 years), "detoxification" of patients with coexisting chronic daily headache due to medication overuse, and no current history of other preventive headache medications.[89]

BOTOX blocks neuromuscular transmission by binding to acceptor sites on motor or sympathetic nerve terminals, entering the nerve terminals, and inhibiting the release of acetylcholine. This inhibition occurs as the neurotoxin cleaves SNAP -25, a protein integral to the successful docking and release of acetylcholine from vesicles situated within nerve endings. When injected intramuscularly at therapeutic doses, BOTOX produces partial chemical denervation of the muscle resulting in a localized reduction in muscle act ivity. In addition, the muscle may atrophy, axonal sprouting may occur, and extrajunctional acetylcholine receptors may develop. There is evidence that reinnervation of the muscle may occur, thus slowly reversing muscle denervation produced by BOTOX.
Many times, effects on spasticity are longer lasting. It is not clear if this is due to breaking down patterned movements (many muscles contracting together rather than singly) or from allowing weak muscles to get stronger over time (that were overpowered before by more spastic muscles pulling against them). It is vital to have close follow-up after the injections to figure out the best course of treatment.
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.
In response to the occurrence of these side effects, in 2008 the U.S. Food and Drug Administration notified the public of the potential dangers of the botulinum toxin as a therapeutic. Namely, they warned that the toxin can spread to areas distant from the site of injection and paralyze unintended muscle groups, especially when used for treating muscle spasticity in children treated for cerebral palsy.[28] In 2009, the FDA announced that boxed warnings would be added to available botulinum toxin products, warning of their ability to spread from the injection site.[29] Additionally, the FDA announced name changes to several botulinum toxin products, meant to emphasize that the products are not interchangeable and require different doses for proper use. Botox and Botox Cosmetic were renamed onabotulinumtoxinA, Myobloc was renamed rimabotulinumtoxinB, and Dysport name renamed abobotulinumtoxinA.[29] In conjunction with this, the FDA issued a communication to health care professionals reiterating the new drug names and the approved uses for each.[30] A similar warning was issued by Health Canada in 2009, warning that botulinum toxin products can spread to other parts of the body.[31]
