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.
BTX-A is now a common treatment for muscles affected by the upper motor neuron syndrome (UMNS), such as cerebral palsy, for muscles with an impaired ability to effectively lengthen. Muscles affected by UMNS frequently are limited by weakness, loss of reciprocal inhibition, decreased movement control and hypertonicity (including spasticity). In January 2014, Botulinum toxin was approved by UK's Medicines and Healthcare Products Regulatory Agency (MHRA) for the treatment of ankle disability due to lower limb spasticity associated with stroke in adults. Joint motion may be restricted by severe muscle imbalance related to the syndrome, when some muscles are markedly hypertonic, and lack effective active lengthening. Injecting an overactive muscle to decrease its level of contraction can allow improved reciprocal motion, so improved ability to move and exercise.
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.
Pharmaceutical companies are not without blame. One reason why insurers impose step therapy is high drug prices. Botox, which is made from the toxin of certain bacteria, is much more expensive than other migraine treatments like beta blockers, which are available as generics. Botox costs about $4,800 a year, but with injection fees, treatment can cost up to $10,000 a year. “They could lower the price,” says Loder. “Their goal is to maximize return on investment for their stockholders. That’s not the same thing as maximizing benefits for patients, unfortunately.”
If, however, you are on a budget, you might want to wait until the end of the year to get your Botox injections. Botox promotions, whether from the Brilliant Distinctions program or from individual doctor's offices, are more common towards the end of the year when people want to get touch ups and look their best for the holidays. However, if someone is offering Botox for a ridiculously cheap price (like you sometimes see on deal websites like Groupon.com), that should raise some red flags. You tend to get what you pay for and in my experience with my mom's Botox treatments, it is better to overpay than underpay. Don't get Botox from a shady place just because it's cheap. Remember, you are not only paying for the units of Botox per treatment, you are also paying for the skill and expertise of the doctor. So make sure you get Botox from a well-trained, reputable physician!
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.
Baby Botox can also be used as an upkeep strategy. "I really think of it as small maintenance doses of Botox over time instead of standard doses given at three- to six-month intervals," says Smith. "The other term that describes this well is 'tweakment' — subtle changes done over a longer period of time using lower doses of product at each treatment."
Postmarketing reports indicate that the effects of BOTOX® 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.
In 1998, David E.I. Pyott became CEO of Allergan. He was enthusiastic about Botox's wrinkle-reducing potential, he says, and pushed the company to conduct a series of studies on the matter. In 2002, Botox earned FDA approval for so-called frown lines--wrinkles between eyebrows--marking the first time a pharmaceutical drug was given the green light for a strictly cosmetic purpose. In 2001, the year before Botox was approved for wrinkles, it generated about $310 million in sales. By 2013, the year it was approved for overactive bladder, Allergan reported nearly $2 billion in revenue from Botox.
"As we get older, we lose volume in our face and hyaluronic acid filler can be used as a replacement,” explains Wexler. "For younger women, injections can be used to treat areas with acne scarring or hollowness under the eyes." During your ‘20s, when the face is at its fullest and healthiest, it has been argued that a shadowy gaze can even be quite charming. But in other cases, hereditary dark circles can result in a persistently tired look, which is where a few drops of filler under the eyes may be useful. As top dermatologist David Colbert, M.D. is quick to note, however, too much Botox and filler distorts the face and as a result will make you appear older. “When the line is crossed everyone starts looking like they are related," he also cautions of a uniform cookie-cutter appearance that lacks character or individuality. Or worse. “It’s a snowball effect of people liking something, coming back too soon [for even more], and then it gets too heavy,” adds Wexler.
When I wean patients off of treatment, I do not change the dose but rather delay the treatment cycle to 16 weeks and monitor headaches in the last 4 weeks. If the patient remains well-controlled, I increase the treatment window to 20 weeks, and so on. I use this method to establish the level at which patients need reinjection to prevent breakthrough headaches.11-13
Spread of toxin effects.The effect of botulinum toxin may affect areas away from the injection site and cause serious symptoms including: loss of strength and all-over muscle weakness, double vision, blurred vision and drooping eyelids, hoarseness or change or loss of voice, trouble saying words clearly, loss of bladder control, trouble breathing, trouble swallowing.
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.
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).
A double-blind, placebo-controlled study enrolled patients who had extended histories of receiving and tolerating BOTOX injections, with prior individualized adjustment of dose. The mean BOTOX dose administered to patients in this study was 236 Units (25th to 75th percentile range of 198 Units to 300 Units). The BOTOX dose was divided among the affected muscles [see Clinical Studies].
Botox treatments can help reduce symptoms of migraine headaches, including nausea, vomiting, and sensitivity to lights, sounds, and smells. After you receive Botox injections, it may take as long as 10 to 14 days for you to experience relief. In some cases, you may not experience any relief from your symptoms following your first set of injections. Additional treatments may prove more effective.
Onabotulinumtoxin A (trade name Botox) received FDA approval for treatment of chronic migraines on October 15, 2010. The toxin is injected into the head and neck to treat these chronic headaches. Approval followed evidence presented to the agency from two studies funded by Allergan showing a very slight improvement in incidence of chronic migraines for migraine sufferers undergoing the Botox treatment.
Remember that the skill of the injector is extremely important when considering Botox injections. Because Botox can have some very obvious and embarrassing side effects like drooping eyelids, blurry vision, and excessive bruising around the injection site, it's important to consult with an experienced injector. Unlike dermal fillers which can be melted away with a follow-up injection of hyaluronidase, there's not much you can do about a bad Botox experience other than wait it out.

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.
“Your doctor still has to be willing to do the work of filing a waiver and they don’t get reimbursed for that work, so they don’t like to do it,” Hoffman says. Plus, there’s a federal law called ERISA that exempts certain types of employer-provided health plans, called self-funded plans, from the requirements of state laws. So, for roughly a quarter of Americans who have these health plans, the state limitations to step therapy don’t apply.
I would caution against shopping around for cheap Botox. There are practitioners than offer bargain prices that are not sustainable from a business standpoint. They may be diluting their Botox or injecting less units than advertised. Also, some practitioners charge less per unit of Botox but inject significantly more Botox than is required to achieve the optimal outcome. For instance, 60 units of Botox at $10/unit is more expensive than 45 well placed units at $12/unit.
Patients with compromised respiratory status treated with BOTOX for spasticity should be monitored closely. In a double-blind, placebo-controlled, parallel group study in patients treated for upper limb spasticity with stable reduced pulmonary function (defined as FEV1 40-80% of predicted value and FEV1/FVC ≤0.75), the event rate in change of Forced Vital Capacity (FVC) ≥15% or ≥20% was generally greater in patients treated with BOTOX than in patients treated with placebo (see Table 5).
In overactive bladder patients with analyzed specimens from the two phase 3 studies and the open-label extension study, neutralizing antibodies developed in 0 of 954 patients (0.0%) while receiving BOTOX 100 Unit doses and 3 of 260 patients (1.2%) after subsequently receiving at least one 150 Unit dose. Response to subsequent BOTOX treatment was not different following seroconversion in these three patients.
Ray Chester, an attorney in Austin who has represented several plaintiffs in lawsuits against Allergan, says that just about all the cases he has handled involved off-label use of the drug. In 2014 a New York couple argued that Botox, which they chose to try off-label to treat their son's cerebral-palsy symptoms, caused life-threatening complications. The family was awarded $6.75 million by a jury. Allergan, which initially planned to appeal, ended up privately settling the case with the family, and the terms of the settlement have been kept confidential.
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.
Dr. Schwedt believes ARMR offers hope for patients living with migraine. “ARMR data could lead to breakthroughs in the field,” he says. One hope for ARMR is that it will contribute to the ability for health care providers to use precision medicine to treat their patients. Clinical trials show which migraine therapies are overall effective for groups of people with migraine; however, health care providers are still working to understand which specific therapy is ideal for a particular patient. “One of the challenges we have in this field right now is being able to determine which exact therapy is going to be best for which patient,” Dr. Schwedt says. “For example, we might know that about 50% of patients will benefit from a specific migraine preventive therapy, but we don’t know in advance which 50% that is. I believe the data we’re collecting in ARMR is going to help us get to the stage where we can practice precision medicine, knowing which therapy is most likely to help an individual patient prior to the patient starting that therapy.”
"I had 25 units of Botox done by Dr. Goldberg on my forehead and frown lines. Few days later I could see the result with which I was very happy! [...] I have done Botox few times before with other specialists, after which my face would resemble a doll [...] However, after procedure with Dr. Goldberg, I am still able to lift my eyebrows and frown without forming any wrinkles." – from Dinara D.'s review of Alexander Golberg Physician PC in New York.
Facelift: What you need to know A facelift aims to make the face look more youthful. The procedure can remove excess skin from the face and smooth wrinkles. However, it may not be suitable for everyone. Complications can occur, for example, infections, especially in people with existing health conditions. Relapse and scarring are also possible. Read now
