Study responders were defined as patients who showed at least a 2-grade improvement from baseline value on the HDSS 4 weeks after both of the first two treatment sessions or had a sustained response after their first treatment session and did not receive re-treatment during the study. Spontaneous resting axillary sweat production was assessed by weighing a filter paper held in the axilla ov er a period of 5 minutes (gravimetric measurement). Sweat production responders were those patients who demonstrated a reduction in axillary sweating from baseline of at least 50% at week 4.

It’s been a little over three weeks. The neurologist said that after two weeks, my migraines and headaches should be substantially reduced. I haven’t spoken about it much even to people close to me because I didn’t want to jinx it, but right around the two-week mark, my headaches faded. I did have a migraine the day after the injections, followed by a lingering headache for about a week, but my neurologist didn’t think it was caused by the Botox. I know my body and have a feeling it was, especially because the introduction or removal of medication can exacerbate lupus symptoms and flares, so I was put on a prednisone taper just to be safe.
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]
The initial listed doses of the reconstituted BOTOX [see Preparation And Dilution Technique] typically create paralysis of the injected muscles beginning one to two days after injection and increasing in intensity during the first week. The paralysis lasts for 2-6 weeks and gradually resolves over a similar time period. Overcorrections lasting over six months have been rare. About one half of patients will require subsequent doses because of inadequate paralytic response of the muscle to the initial dose, or because of mechanical factors such as large deviations or restrictions, or because of the lack of binocular motor fusion to stabilize the alignment .

But it could be something else altogether. In 2008, Matteo Caleo, a researcher at the Italian National Research Council's Institute of Neuroscience in Pisa, published a controversial study showing that when he injected the muscles of rats with Botox, he found evidence of the drug in the brain stem. He also injected Botox into one side of the brain in mice and found that it spread to the opposite side. That suggested the toxin could access the nervous system and the brain.
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.

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.


When BOTOX (4, 8, or 16 Units/kg) was administered intramuscularly to pregnant mice or rats two times during the period of organogenesis (on gestation days 5 and 13), reductions in fetal body weight and decreased fetal skeletal ossification were ob served at the two highest doses. The no-effect dose for developmental toxicity in these studies (4 Units/kg) is approximately equal to the human dose of 400 Units, on a body weight basis (Units/kg).

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
It will not affect the nerves that cause sensation, or make you feel numb. When it is used correctly, it can lift the brow to give an appealing and sincere look. "But if too much is injected in the danger zone—the horizontal lines in the forehead—you can look Spocked, as in Spock from Star Trek," says Jean Carruthers, a Vancouver eye surgeon who, with her husband, Alastair, coauthored the first paper on the cosmetic benefits of Botox in 1989. That's why it's important to be treated by an experienced doctor who can judge the size of your muscles and how much Botox you will need.
Marrying ophthalmology to dermatology, Jean and Alistair Carruthers observed that blepharospasm patients who received injections around the eyes and upper face also enjoyed diminished facial glabellar lines (“frown lines” between the eyebrows), thereby initiating the highly-popular cosmetic use of the toxin.[52] Brin, and a group at Columbia University under Monte Keen made similar reports.[53] In 2002, following clinical trials, the FDA approved Botox Cosmetic, botulinum A toxin to temporarily improve the appearance of moderate-to-severe glabellar lines.[54] The FDA approved a fully in vitro assay for use in the stability and potency testing of Botox in response to increasing public concern that LD50 testing was required for each batch sold in the market.[55][56]
So let's talk about it, shall we? And before we do, let's also get one thing out of the way—I've had Botox. And it was free. As a result, I've found myself trying to field questions about the price and popularity of certain treatments, and many times my knowledge on the subject comes up short. To remedy that fact, I decided to do some research into the real, unexaggerated pricing for injections and what each formula and technique will actually do to your face. Below find the answers you may have been looking for but didn't feel comfortable asking.

"Neurotoxins and facial fillers are my most popular injectable treatments," notes Zeichner. "Neurotoxins like Botox and Dysport relax muscles under the skin that can lead to folding and lines, specifically frown lines between the eyebrows. Facial fillers are my favorite cosmetic procedure in the office—there's really an art to it. I exclusively use hyaluronic acid fillers because they are safe and long-lasting."

In 1986, Oculinum Inc, Scott's micromanufacturer and distributor of botulinum toxin, was unable to obtain product liability insurance, and could no longer supply the drug. As supplies became exhausted, patients who had come to rely on periodic injections became desperate. For 4 months, as liability issues were resolved, American blepharospasm patients traveled to Canadian eye centers for their injections.[48]

In both studies, significant improvements compared to placebo in the primary efficacy variable of change from baseline in daily frequency of urinary incontinence episodes were observed for BOTOX 100 Units at the primary time point of week 1 2. Significant improvements compared to placebo were also observed for the secondary efficacy variables of daily frequency of micturition episodes and volume voided per micturition. These primary and secondary variables are shown in Tables 19 and 20, and Figures 5 and 6.

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.

For most of our guests, the effects of the treatment can last anywhere from 3-6 months. Many factors can influence how long the effects last. As the product wears off, muscle action returns gradually, & the previously treated lines & wrinkles may begin to reappear, and need to be treated again. With repeated treatment, the lines and wrinkles often appear less severe than before, as the muscles are being trained to relax.Some of these factors that may shorten or lengthen the effects include:
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.

If going back for additional treatments three or four times a year sounds like a lot of treatments, the good news is that the more Botox treatments you get, the fewer Botox units you'll need. With each repeat Botox session, the frontalis muscle and other facial muscles surrounding Botox injection sites get a little weaker and become "trained" to not contract.

Make sure your practitioner is very experienced at Botox injections and is a respected medical professional. A salon stylist, for example, is not an appropriate person to administer Botox, because he or she would not have emergency equipment or sufficient medical knowledge if something went wrong. Some disreputable people have reportedly administered injections that were over- or under-diluted with saline, as well as counterfeit solutions that didn't contain Botox at all.

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]

I usually keep my patients on migraine preventative medications until we have seen sufficient relief of migraine to warrant a taper to a lower dose or even an attempt at medication discontinuation. Patients are free to use their typical migraine abortive medications for breakthrough migraines. There are some patients that find that they still require their other anti-migraine medications for full migraine control.

I asked this question as Ravitz was putting the first needles in my face, which was probably a mistake as I get anxious easily. However, she assured me that the side effects of Botox typically don't happen at the doses prescribed for migraines, and even if the scary-sounding side effects you read about online do occur (such as one-side paralysis and eye droops), they aren't particularly dangerous and last four to six weeks.
Botox is an injectable drug made from a toxic bacterium called Clostridium botulinum. When you eat the toxin produced by this bacterium, it causes a life-threatening form of food poisoning, known as botulism. But when you inject it into your body, it causes different symptoms. It blocks certain chemical signals from your nerves, causing temporary paralysis of your muscles.
So when I first propositioned my husband about the idea of me getting a bit of Botox for the furrowed brow I've earned from a decade of writing and editing behind a computer screen, he was adamantly against it. And frankly, I was a bit scared too. I mean, isn't Botox poison? As an idealistic 21 year old, it was easy to say that I'd never put that stuff in my body, that "poison." Now, I'm not so sure.
“A younger face has a heart shape, and an older face is a little more bottom-heavy and square,” says Dr. Matarasso. “But if you put toxin in both sides, you are not reducing the movement of the muscle, you are thinning the muscle out a bit. You can restore a youthful look. It’s not as dramatic or quick-acting as other areas, but it can be a nice way to improve the contour of the face.”

Temporary bruising is the most common side effect of Botox. Headaches, which resolve in 24-48 hours, can occur, but this is rare. A small percentage of patients may develop eyelid drooping. This usually resolves in three weeks. This usually happens when the Botox moves around so you shouldn't rub the treated area for 12 hours after injection or lay down for three to four hours.

Proper refrigeration at temperatures below 3 °C (38 °F) retards the growth of Clostridium botulinum. The organism is also susceptible to high salt, high oxygen, and low pH levels.[citation needed] The toxin itself is rapidly destroyed by heat, such as in thorough cooking.[72] The spores that produce the toxin are heat-tolerant and will survive boiling water for an extended period of time.[73]


Patients with smaller neck muscle mass and patients who require bilateral injections into the sternocleidomastoid muscle for the treatment of cervical dystonia have been reported to be at greater risk for dysphagia. Limiting the dose injected into the sternocleidomastoid muscle may reduce the occurrence of dysphagia. Injections into the levator scapulae may be associated wit h an increased risk of upper respiratory infection and dysphagia.
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.

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.
Other side effects of BOTOX® and BOTOX® Cosmetic include: dry mouth, discomfort or pain at injection site, tiredness, headache, neck pain, eye problems: double vision, blurred vision, decreased eyesight, drooping eyelids, swelling of eyelids, dry eyes, and drooping eyebrows. In people being treated for urinary incontinence other side effects include: urinary tract infection, painful urination, and/or inability to empty your bladder on your own. If you have difficulty fully emptying your bladder after receiving BOTOX®, you may need to use disposable self-catheters to empty your bladder up to a few times each day until your bladder is able to start emptying again.
