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.
Dysphagia occurred in 2% of subjects in the clinical trials in the setting of administration-site reactions, eg, pain, swelling, and induration of the submental area; all cases of dysphagia resolved spontaneously (range 1-81 days, median 3 days). Avoid use of KYBELLA® in patients with current or prior history of dysphagia as treatment may exacerbate the condition.
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.
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.
Just because not every cosmetic Botox procedure is FDA-approved doesn't mean it's not safe and effective, if done properly. Off-label procedures are still within the standard of care, and there are tons of them. “There are so many non-FDA-approved applications for Botox,” says dermatologist Dendy Engelman, MD. “It can be used to decrease scalp-sweating (which helps prolong blowouts), correct a droopy nasal tip (called nasal-tip ptosis), fix brow asymmetry, minimize bunny lines from wrinkling your nose, decrease skin oiliness, minimize the appearance of pores...” The list goes on and on.
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.
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. On August 10, the company acquired Oculeve for $125 million. On August 31, the company acquired Naurex for an upfront payment of $560 million. 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. On October 1, the company acquired Kythera Biopharmaceuticals, a company focused on the medical aesthetics market, for $2.1 billion. On November 4 the company announced the acquisition of Northwood Medical Innovation, developer of earFold, a medical device to correct protruding ears. 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.
When pregnant rats received single intramuscular injections (1, 4, or 16 Units/kg) at three different periods of development (prior to implantation, implantation, or organogenesis), no adverse effects on fetal develop ment were observed. The developmental no-effect level for a single maternal dose in rats (16 Units/kg) is approximately 2 times the human dose of 400 Units, based on Units/k g.
The safety and effectiveness for the treatment of anatomic regions other than the mid-face with JUVÉDERM VOLUMA® XC; facial wrinkles and folds with JUVÉDERM® Ultra XC, JUVÉDERM® Ultra Plus XC, and JUVÉDERM VOLLURE™ XC; and the lips and perioral area with JUVÉDERM® Ultra XC and JUVÉDERM VOLBELLA® XC have not been established in controlled clinical studies
Still, there have been enough concerns that the FDA instituted a REMS (Risk Evaluation and Mitigation Strategy) requirement for all botulinum toxin preparations that specifically addresses the issues of distant spread of the toxin and the risk of problems, leading to death, from swallowing or breathing issues in certain patients who may be susceptible after botulinum toxin treatment. All products, including Dysport, Myobloc, Xeomin, and Botox, are monitored via this strategy. This is specifically aimed at a certain population of patients receiving more than the usual doses of botulinum toxin and not aimed at the casual user of Botox, per se.
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:
Symptoms of overdose are likely not to be present immediately following injection. Should accidental injection or oral ingest ion occur or overdose be suspected, the person should be medically supervised for several weeks for signs and symptoms of systemic muscular weakness which could be local, or distant from the site of injection [see BOX WARNING and WARNINGS AND PRECAUTIONS]. These patients should be considered for further medical evaluation and appropriate medical therapy immediately instituted, which may include hospitalization.
I had a consult and the doctor quickly realized that I was a candidate for Botox. He ordered an MRI and doppler of my brain to make sure everything else was A-OK, and then the rest was just waiting on my insurance company. With Botox (I’m not sure if it’s all Botox or just prescription), the insurance company orders it from a pharmacy and sends it to the doctor.
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.
That Groupon offer might be tempting, but Dr. Tutela recommends doing a thorough vetting of your practitioner’s history and methods before signing up for treatment. “I think it is important to ask any provider if they perform that procedure frequently, to gauge their experience,” he says. He also suggests to ask if they’ve experienced any major complications and to check their online reviews. “You can get a sense of how you will be treated and what kind of experience other patients have had,” Dr. Tutela says. “Many of those low-cost, high-volume practices are loaded with horrible reviews from disappointed patients.”
Not much. Results begin to show in a couple of days and develop gradually over the course of two weeks. "I tell anyone preparing for a big event to have shots two weeks ahead of time," says Kane. Some observers believe Dysport sets in faster than Botox, but that has not been proven in a study. Patients taking medications that contain aspirin or NSAIDs can develop pinpoint blue bruising. Patients can wear makeup immediately but should avoid heavy workouts for 24 hours, says Carruthers.
Botox has not been approved for any pediatric use. It has, however, been used off-label by physicians for several conditions. including spastic conditions in pediatric patients with cerebral palsy, a therapeutic course that has resulted in patient deaths. In the case of treatment of infantile esotropia in patients younger than 12 years of age, several studies have yielded differing results.[better source needed]

In addition to glabellar lines, Botox is used to eradicate crow’s feet, frown lines, and lines and furrows in the forehead. Whereas treating crow's feet and forehead lines with Botox was for many years an off-label use, the toxin has since received FDA approval for both uses. Botox is also approved to treat a variety of medical conditions, including ocular muscle spasms, problems with eye coordination, severe armpit perspiration, migraine headaches, overactive bladder, urinary incontinence related to nerve damage from conditions such as multiple sclerosis and spine injury. Botox is being studied to determine if it might be useful in treating conditions such as knee and hip osteoarthritis, temporomandibular joint disorder (TMJ) and benign prostatic hyperplasia (BPH).
In detrusor overactivity associated with neurologic condition patients with analyzed specimens in the drug development program (including the open-label extension study), neutralizing antibodies developed in 3 of 300 patients (1.0%) after receiving only BOTOX 200 Unit doses and 5 of 258 patients (1.9%) after receiving at least one 300 Unit dose. Following development of neutralizing antibodies in these 8 patients, 4 continued to experience clinical benefit, 2 did not experience clinical benefit, and the effect on the response to BOTOX in the remaining 2 patients is not known.
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.
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).
Preventative Botox has been getting lots of buzz. “It can potentially have a preventive effect on dynamic wrinkles, which are caused by underlying muscle movement,” Shah explains. “That being said, muscle movement is only one factor that contributes to the development of wrinkles, so Botox may not be completely preventive.” (Some other wrinkle causes: sun exposure, smoking, and diet.)
Tell your doctor if you have received any other botulinum toxin product in the last 4 months; have received injections of botulinum toxin such as Myobloc®, Dysport®, or Xeomin® in the past (tell your doctor exactly which product you received); have recently received an antibiotic injection; take muscle relaxants; take allergy or cold medicines; take sleep medicine; take aspirin-like products or blood thinners.
