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.
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).

Botox is a neurotoxin derived from the bacterium Clostridium botulinum. Ingested in contaminated food, it can interfere with key muscles in the body, causing paralysis and even death. But when injected in tiny doses into targeted areas, it can block signals between nerves and muscles, causing the muscles to relax. That's how it smooths wrinkles: when you immobilize the muscles that surround fine lines, those lines are less likely to move--making them less noticeable. It's also why it's FDA-approved to treat an overactive bladder: Botox can prevent involuntary muscle contractions that can cause people to feel like they have to pee even when they don't.
Wrinkles, whether they be fine line or deep furrows, typically appear on areas of the body that receive a high amount of exposure to the sun. Smoking, light skin type, hairstyle, the way you dress, your occupational and recreational habits, and heredity are all factors that promote wrinkling. Medical treatments for wrinkles include antioxidants, moisturizers, alpha-hydroxy acids, and vitamin A acid. Cosmetic procedures that treat wrinkles include dermabrasion, microdermabrasion, glycolic acid peels, laser resurfacing, Botox, and fillers.

But in a recent Fat Mascara podcast, NYC dermatologist Pat Wexler, MD, said this is a myth. And Dr. Matarasso falls somewhere in-between. “For aesthetic or cosmetic reasons, does a 19-year-old need this? No. Does a 26-year-old need this for aesthetic purposes? Highly doubtful. But, hey, listen, if you are like, ‘I am looking at my parents, I am looking at my genes, and I want to stay proactive,’ it is not unreasonable to introduce it in small amounts.”
Who is injecting your Botox? Injecting Botox is deceptively easy. After all, it looks like the nurse or physician just takes a little fluid and squirts into facial muscles, and Walla ! Perfection! The answer is No! You should choose a specialist with years of experience and the ability to assess your facial features to create the best treatment plan possible. Because when Botox is injected in the wrong place it can produce unwanted side-effects that you might find disturbing. For instance if the injector “chases” a wrinkle across your forehead and it happens to be too close to your central eyebrow then the Botox or Dysport can drift downward inhibiting a muscle that lifts your eyelid resulting in a drooped upper eyelid. I know you don’t want that! Or if the practitioner injects only your “11” frown lines between your brows and does not inject other areas of your brow to balance out the effect then you may get a “boomerang”brow – a “Spock”-like overarched  brow that looks hideous. So like everything else experience counts but more experience usually translates into a more expensive treatment sessions. However, avoiding complications can save you money and aggravation in the long run.
Botox lasts only around three months (or more when you first start getting injections), so get ready to go in for maintenance every three to six months. Because it’s only meant to temporarily relax your muscles, it wears off over time, and you’ll notice your wrinkle start to appear again. “As skin ages, the skin loses elasticity and collagen breaks down, so constant muscle and skin contraction can create more permanent creases (wrinkles). Within a few months of injecting the botox, the body makes new acetylcholine receptors, and the nerves are able to conduct their impulses again,” Dr. Shainhouse explains. “You must use neurotoxins continuously in order to reduce muscle movement and prevent long-term skin creasing.” Find out more secrets from dermatologists about how to prevent and treat wrinkles.
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.

Patients with diabetes mellitus treated with BOTOX® were more likely to develop urinary retention than nondiabetics. In clinical trials, 12.3% of patients (10/81) with diabetes developed urinary retention following treatment with BOTOX® 100 Units vs 0% of patients (0/69) treated with placebo. In patients without diabetes, 6.3% of patients (33/526) developed urinary retention following treatment with BOTOX® 100 Units vs 0.6% of patients (3/516) treated with placebo.


Most insurance providers now cover the expense of Botox injections when they’re used to treat chronic migraines. If you don’t have insurance, or your insurance won’t cover the cost of the procedure, it may cost you several thousand dollars. Before you begin receiving injections, talk to your insurance company. In some cases, they may require you to undergo other procedures or tests before they will cover the costs of Botox treatments.

"Botox inactivates the muscle," Rowe tells SELF, "and therefore the muscle doesn't fire and pull on skin, thus reducing animation." However, when I asked Sobel what was happening during the exact incubation, he told SELF that "I'm not sure if anyone can give you an answer&we've noticed that when we inject it, it just takes three of four days for you to see the muscle contract."

Botulinum toxin is used to treat a number of disorders characterized by overactive muscle movement, including post-stroke spasticity, post-spinal cord injury spasticity, spasms of the head and neck,[8] eyelid,[9] vagina,[10] limbs, jaw, and vocal cords.[11] Similarly, botulinum toxin is used to relax clenching of muscles, including those of the oesophagus,[12] jaw,[13] lower urinary tract and bladder,[14] or clenching of the anus which can exacerbate anal fissure.[15] It may also be used for improper eye alignment.[16] Botulinum toxin appears to be effective for refractory overactive bladder.[17]
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.

Simply put, "Baby Botox" uses a lower volume of Botox (a.k.a. botulinum toxin injections) than a traditional injection to smooth fine lines and wrinkles. "Instead of using 25 units in an area, you may use 10 units," Melissa Doft, a board-certified plastic surgeon in New York City, tells Allure. "I have many patients who ask for half the normal dose, as they do not want to look frozen but are tired of wrinkles in photos. First-time Botox patients are perfect for this."

Medicine to help the patient relax may be given in cases where the patient has not handled shots well in the past. If the patient has another procedure coming up, these shots can often be done at this time. Let the Rehabilitation Medicine office (513-636-7480) know if a procedure or surgery will be done in the future or if sedation is being discussed for injections in the clinic setting.

The recommended dose is 50 Units per axilla. The hyperhidrotic area to be injected should be defined using standard staining techniques, e.g., Minor's Iodine-Starch Test. The recommended dilution is 100 Units/4 mL with 0.9% preservative -free sterile saline (see Table 1). Using a sterile 30 gauge needle, 50 Units of BOTOX (2 mL) is injected intradermally in 0.1 to 0.2 mL aliquots to each axilla evenly distributed in multiple sites (10-15) approximately 1-2 cm apart.
In the event of overdose, antitoxin raised against botulinum toxin is available from the Centers for Disease Control and Preventio n (CDC) in Atlanta, GA. However, the antitoxin will not reverse any botulinum toxin-induced effects already apparent by the time of antitoxin administration. In the event of suspected or actual cases of botulinum toxin poisoning, please contact your local o r state Health Department to process a request for antitoxin through the CDC. If you do not receive a response within 30 minutes, please contact the CDC directly at 1-770-488-7100. More information can be obtained at http://www.cdc.gov/mmwr/preview/mmwrhtml/mm5232a8.htm.
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.
Ratings on RealSelf.com (www.RealSelf.com) show a satisfaction rate of 65% for Botox, which is on par with other treatments such as Restylane, Juvederm, and Perlane and slightly higher than Xeomin and Dysport. Longer-term treatments, such as Ultherapy facial tightening and Liposuction/SmartLipo achieve ratings in the 80% and above area, while others such as CoolSculpting (Zeltiq) achieve ratings in the 70% area. This may reflect upon the short-term nature of all botulinum toxins versus the longer-term nature of these other procedures.
Micropigmentation, or permanent makeup, is a procedure in which iron oxide pigment is injected into the dermis. This procedure can improve the appearance of thin eyebrows and lips and may be beneficial for those with makeup allergies. Swelling is common after the procedure. The patient may be instructed to apply ice and/or ointment to the treated area.
BOTOX for migraines is an innovative, FDA-approved procedure. BOTOX is a unique approach to migraine relief that is proving to be highly effective for many patients living with the condition. Rather than reducing the symptoms of an existing headache, BOTOX works to prevent future headaches, and helps avoid the continued use of powerful prescription pain medications.
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]
Other potential adverse events that may occur with breast implant surgery include: asymmetry, breast pain, breast/skin sensation changes, capsular calcification, delayed wound healing, hematoma, hypertrophic scarring/scarring, implant extrusion, implant malposition, implant palpability/visibility, infection, nipple complications, redness, seroma, swelling, tissue/skin necrosis, wrinkling/rippling.
That’s enough to generate buzz on the patient forums like RealSelf among those who have tried it: “My neck is killing me” wrote one user;  I’ve got “Stiffness, pain in the neck, headache and can’t look down” reported another. Like anything, results vary widely. “I have since felt nauseous and dizzy on and off every day, as well as have blurry vision.
A migraine requires only two of the following headache features: a unilateral distribution (one-sided), pulsatile quality (throbbing), moderate or severe pain (more than 5 out of 10), and aggravation by physical activity (such as bending over). In addition, to diagnose migraine, only one of the following is required: nausea or vomiting or sensitivity to light and noise.
Though there's still more research to be done on Botox for migraines and doctors aren't yet completely sure why the procedure is effective, they have some ideas. Ravitz tells me, "What [Botox] does is paralyze nerve terminals. Essentially, nerve terminals transmit pain, but they also produce pain substances while they’re doing that, and it completely paralyzes that process." She says that it stops the process of pain patterning and it also relaxes the muscles.
There are no studies or adequate data from postmarketing surveillance on the developmental risk associated with use of BOTOX in pregnant women. In animal studies, administration of BOTOX during pregnancy resulted in adverse effects on fetal growth (decreased fetal weight and skeletal ossification) at clinically relevant doses, which were associated with maternal toxicity [see Data)].
Prior to injection, reconstitute each vacuum-dried vial of BOTOX with only sterile, preservative-free 0.9% Sodium Chloride Injection USP. Draw up the proper amount of diluent in the appropriate size syringe (see Table 1, or for specific instructions for detr usor overactivity associated with a neurologic condition see Section 2.3), and slowly inject the diluent into the vial. Discard the vial if a vacuum does not pull the diluent into the vial. Gently mix BOTOX with the saline by rotating the vial. Record the date and time of reconstitution on the space on the label. BOTOX should be administered within 24 hours after reconstitution. During this time period, reconstituted BOTOX should be stored in a refrigerator (2° to 8°C).
Not a Botox patient? Listen anyway. This is good practice for asking the price for other medical procedures like an MRI or a colonoscopy, where the information can be much harder to get. The common replies you could get: “What’s your insurance?” “We can’t tell you because it depends on your deductible.” “We don’t know.” “You’ll have to call billing.”

This is because the discretionary procedures tend to be out of pocket, and providers are used to answering the question: how much does it cost? An MRI, on the other hand, might have several prices: A sticker price, a negotiated or reimbursed rate (what the insurance company pays), the rate that Medicare and Medicaid pay for treatments for people who are older and those who have low income, an out-of-network price, and so on. We know about this because we’ve done pricing surveys for about 35 common procedures in seven U.S. metro areas, collecting cash or self-pay prices for both medically necessary procedures (an MRI, a colonoscopy) and discretionary procedures (Botox, Lasik).
Please note, there are no guaranteed results with BOTOX and results may vary from patients to patient. Though BOTOX is not effective for all types of headaches, about 90% of MRC’s patients report that their migraines are less frequent and not as severe after BOTOX treatment. In clinical trials, patients reported seven to nine fewer headaches per month. In a study by A. H. Elkind, P. O’Carroll, A. Blumenfeld, R. DeGryse, and R. Dimitrova, a standard course of treatment brought patients these results:
Don’t be a pill. You're more likely to get a bruise at the site of the needle injection if you're taking aspirin or ibuprofen; these medications thin the blood and increase bleeding which causes the bruise. Skip the pills for two weeks in advance of your treatment. You should also tell your doctor -- before treatment -- about any supplements you're taking, even if they're "natural," because some (such as fish oil pills, gingko, or vitamin E) also thin blood. Your doctor may ask you not to use those supplements for two weeks before your treatment.

I usually charge $12 a unit for botox. The number of units depends on the site. The "eleven" lines or glabellar area I usually use 20 units. Also I used 20-30 units for the forehead. In the crows feet I use about 15 units per side or 30 units total. To give a Botox brow lift I use 5 units total. Finally to give a patient a natural smile or soften the sad look of the mouth I use about 10 units. You can calculate the math to determine the cost depending on what you would like to get. Botox cost is going to vary by location as overhead will be different in different areas of the country. Maintaining a park avenue office is much more costly than an office in New Jersey so my price may be lower than someone in Manhattan. Someone in Bucks County Pennsylvania may have lower costs and thus lower prices still.

BOTOX® increases the incidence of urinary tract infection. Clinical trials for overactive bladder excluded patients with more than 2 UTIs in the past 6 months and those taking antibiotics chronically due to recurrent UTIs. Use of BOTOX® for the treatment of overactive bladder in such patients and in patients with multiple recurrent UTIs during treatment should only be considered when the benefit is likely to outweigh the potential risk.

Receiving Botox injections for migraines is a straightforward outpatient procedure. The skin in the area to be injected is cleaned. Most injections are administered in the forehead area, usually above the eyes or where “worry lines” might occur. Because this area may be sensitive or patients may be experiencing hypersensitivity to pain, a topical anesthetic may be applied before the injection.


I’ve been getting injections for migraine and cervical dystonia for a couple of years. Thank GAWD for Medicaid to cover it. I went 2 days ago for my 12 week appt. The relief was instantaneous. I’ve been under an immense amount of stress due to losing my only child 5 months ago. I’m still alive and virtually headache free. Botulism…who knew?! But…THANK YOU♡
Keep in mind that the price is often reflective of experience and quality. Botox injections gone wrong can lead to a  "Botox face", a droopy eyelid, migraine headaches, and frozen facial expressions. Unskilled or inexperienced injectors may also cause excessive bruising and more asymmetric results. Experienced plastic surgeons and dermatologists who are good Botox injectors can be much more expensive than injectors with limited experience.
Deaths as a complication of severe dysphagia have been reported after treatment with botulinum toxin. Dysphagia may persist f or several months, and require use of a feeding tube to maintain adequate nutrition and hydration. Aspiration may result from severe dysphagia and is a particular risk when treating patients in whom swallowing or respiratory function is already compromised.

Injection description is very important. It is best to describe the injections as a pinch rather than a bee sting, and to explain that the injections are shallow, with only a half-inch needle. As a result of the superficial technique used with the injections, deep anticoagulation can be continued. The procedure is short, and talking to the patient during the procedure about something other than the injections can help alleviate the patient’s anxiety. It is important to describe onabotulinumtoxinA as a purified protein rather than a toxin or a poison. In addition, stating that it relaxes muscles rather than causing paralysis will be reassuring to the patient. In a very anxious patient, the areas to be injected can be iced first or a local anesthetic cream can be applied. Starting with the trapezius muscle can also help, as these injections are the least painful, and the patient cannot see the needle. Finally, it is important to make sure the injections are performed with a sharp needle, and blunt needles are discarded. Thirty-gauge needles only remain sharp for six to eight needle sticks each.
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.
There were 214 subjects evaluated for the open label period, of which 170 progressed into the randomized, blinded treatment p eriod (88 in the BOTOX group, 82 in the placebo group). Patient evaluations continued for at least 10 weeks post-injection. The primary outcome for the study was a dual endpoint, requiring evidence of both a change in the Cervical Dystonia Severity Scale (CDSS) and an increase in the percentage of patients showing any improvement on the Physician Global Assessment Scale at 6 weeks after the injection session. The CDSS quantifies the severity of abnormal head positioning and was newly devised for this study. CDSS a llots 1 point for each 5 degrees (or part thereof) of head deviation in each of the three planes of head movement (range of scores up to theoretical maximum of 54). The Physician Global Assessment Scale is a 9 category scale scoring the physician's evaluation of the patients' status compared to baseline, ranging from 4 to +4 (very marked worsening to complete improvement), with 0 indicating no change from baseline and +1 slight improvement. Pain is also an important symptom of cervical dystonia and was evaluated by separate assessments of pain frequency and severity on scales of 0 (no pain) to 4 (constant in frequency or extremely severe in intensity). Study results on the primary endpoints and the pain-related secondary endpoints are shown in Table 35.
The potency Units of BOTOX 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 DESCRIPTION].
If you have eyelid drooping after a Botox procedure, it is a good idea to let the cosmetic surgeon know because there is a medicine available to help this condition. Any other difficulties, such as difficulty breathing or rashes, should be reported to the surgeon immediately. Bruises are generally gone within one to two weeks, there are other medications available for the treatment of these, such as vitamin K topical treatments (Dr. Holmquist Healthcare CytoActive Post-Procedural Bruise Relief, Revision Skincare Vitamin K Serum, Clinicians Complex Bruise Cream, Glymed Plus Arnica+ Healing Cream).

On April 6, 2016, the company announced it would partner with Heptares Therapeutics in a deal valued up to $3.3 billion to collaborate on the development of a subtype-selective muscarinic agonists for Alzheimer's disease and other major neurological disorders.[21] On April 21, the company announced the acquisition of Topokine Therapeutics for at least $85 million, gaining the phase IIb/III compound XAF5 - a treatment for dermatochalasis.[22] On August 2, the company sold its generic drugs business to Teva Pharmaceutical Industries for $33.4 billion and 100.3 million shares of Teva.[23] On August 11, the company announced the acquisition of ForSight VISION5 for more than $95 million.[24] On September 6, the company acquired RetroSense Therapeutics for more than $60 million, gaining the positive photosensitivity gene therapy treatment, RST-001. RST-001 is to be used in retinas in which rod and cone photoreceptors have degenerated over time, causing in increase in the sensitivity of light hitting the retina.[25] On September 20, the company announced the acquisition of Tobira Therapeutics for $1.695 billion[26] and, a day later, the acquisition of Akarna Therapeutics for $50 million.[27] On October 3, the company sold Anda, its generic drug distribution business, to Teva for $500 million.[28] On October 25, the company acquired Vitae Pharmaceuticals, focused on dermatology treatments, for $639 million.[29] On October 27, the company announced it would acquire Motus Therapeutics, a developer of treatments for gastrointestinal disorders, for $200 million.[30] On November 22, 2016, the company acquired Chase Pharmaceuticals for an upfront payment of $125 million.[31]


The FDA approved such usage in the late 1980s when it was discovered that BOTOX® could stop ailments such as blepharospasm (uncontrolled blinking) and strabismus (lazy eye). Cosmetic physicians have been using BOTOX® for years to successfully treat wrinkles and facial creases. BOTOX® is approved for treatment of frown lines on the forehead, crow’s feet (lines around the eye), and axillary hyperhidrosis (increased sweating of the armpits). Within the past few years, new products that have similar preparations have been introduced into the U.S. market and have been well-received by patients.
The toxin itself is released from the bacterium as a single chain, then becomes activated when cleaved by its own proteases.[11] The active form consists of a two-chain protein composed of a 100-kDa heavy chain polypeptide joined via disulfide bond to a 50-kDa light chain polypeptide.[35] The heavy chain contains domains with several functions: it has the domain responsible for binding specifically to presynaptic nerve terminals, as well as the domain responsible for mediating translocation of the light chain into the cell cytoplasm as the vacuole acidifies.[1][35] The light chain is a zinc metalloprotease and is the active part of the toxin. It is translocated into the host cell cytoplasm where it cleaves the host protein SNAP-25, a member of the SNARE protein family which is responsible for fusion. The cleaved SNAP-25 is unable to mediate fusion of vesicles with the host cell membrane, thus preventing the release of the neurotransmitter acetylcholine from axon endings.[1] This blockage is slowly reversed as the toxin loses activity and the SNARE proteins are slowly regenerated by the affected cell.[1]
