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.
“Most people in their twenties decide to try Botox simply because they want to enhance their appearance, such as relaxing the muscles in their forehead, or because they want to keep their skin looking fresh and young,” Shah says. “Starting earlier is better than later because as the lines get more and more embedded into the skin, Botox is not as effective in eliminating the lines.”
Study 4 included 170 patients (87 BOTOX and 83 placebo) with upper limb spasticity who were at least 6 months post-stroke. In Study 4, patients received 20 Units of BOTOX into the adductor pollicis and flexor pollicis longus (total BOTOX dose =40 Units in thumb muscles) or placebo (see Table 30). Study 5 included 109 patients with upper limb spasticity who were at least 6 months post-stroke. In Study 5, patients received 15 Units (low dose) or 20 Units (high dose) of BOTOX into the adductor pollicis and flexor pollicis longus under EMG guidance (total BOTOX low dose =30 Units, total BOTOX high dose =40 Units), or placebo (see Table 30). The duration of follow-up in Study 4 and Study 5 was 12 weeks.
With the outbreak of World War II, weaponization of botulinum toxin was investigated at Fort Detrick in Maryland. Carl Lamanna and James Duff developed the concentration and crystallization techniques that Edward J. Schantz used to create the first clinical product. When the Army’s Chemical Corps was disbanded, Schantz moved to the Food Research Institute in Wisconsin, where he manufactured toxin for experimental use and generously provided it to the academic community.
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
During treatment, very low doses of Botox® Cosmetic are administered via a few tiny injections directly into the muscles responsible for frown lines between the brows. By blocking the release of a chemical that causes them to contract, Botox® Cosmetic enables them to relax. The effects are very localized and, when administered by an experienced injector, do not affect your ability to smile, laugh, or otherwise show expression. Botox® Cosmetic is the only product of its kind that has been approved for use in this area.
The effects of botulinum toxin are different from those of nerve agents involved insofar in that botulism symptoms develop relatively slowly (over several days), while nerve agent effects are generally much more rapid and can be instantaneous. Evidence suggests that nerve exposure (simulated by injection of atropine and pralidoxime) will increase mortality by enhancing botulinum toxin's mechanism of toxicity.
There have been spontaneous reports of death, sometimes associated with dysphagia, pneumonia, and/or other significant debility or anaphylaxis, after treatment with botulinum toxin. There have also been reports of adverse events involving the cardiovascular system, including arrhythmia and myocardial infarction, some with fatal outcomes. Some of these patients had risk factors including cardiovascular disease. The exact relationship of these events to the botulinum toxin injection has not been established.
The company markets brand products in six therapeutic areas: aesthetics/dermatology/plastic surgery; neurosciences/CNS; eye care; women’s health and urology; GI and cystic fibrosis; and cardiovascular disease and infectious disease.

Some doctors and dermatologists recommend lying down and resting after a treatment, but Ravitz says she doesn't think there's any need for downtime unless a patient experiences pain. It can take about two weeks to work, though some patients start to feel relief from chronic migraines sooner than that. Ravitz tells me, "If it’s going to work for a patient, one round of the treatment typically lasts for around three months." Though everybody metabolizes it at a different rate, getting it done every three months or so has been found to be effective.
Forehead – The horizontal lines and furrows on your forehead will not magically disappear. Which is why you should consider getting a Botox injection before they start to set in permanently. These lines will become more excessive with age, and will age to your appearance.Over time by repeatedly injecting these lines the deeply etched lines will become progressively improved
Sometimes, because of these policies, patients are put on meds that are not approved by the FDA for the treatment of migraines, like the antidepressant amitriptyline and the high blood pressure drug verapamil. “In my experience, [verapamil is] not very effective,” says Elizabeth Loder, chief of the headache division at Brigham and Women’s Hospital in Boston and the former president of the American Headache Society. For the insurance companies, that doesn’t seem to matter. “It’s frustrating to patients, especially when it seems like some of the treatments that they’re required to try have a lot of side effects and haven’t really been tested that carefully for migraines.”
I love talking about migraines. I don't do it to be a downer; I do it because talking about dealing with my chronic migraines may lead to hearing tips from another fellow sufferer, and I've tried nearly everything at this point. I've dealt with migraines for almost two decades, and as anyone who deals with them knows, having a variety of remedies in your toolbox is crucial when the pain hits.
According to the PREEMPT paradigm, one injection of 5 units of onabotulinumtoxinA into four sites (total 20 units) into the frontalis muscle is done. The injection points are located by visually drawing a line up from the medial edge of the supraorbital rim. Patients will be injected into the muscle in the upper third of the forehead at least 1 to 2 fingerbreadths above the corrugator injection site. The lateral muscle injection areas are parallel and approximately 1 fingerbreadth lateral to the medial injection site, which is roughly in line with either the midpupillary line or the lateral edge of the cornea, which is the limbus line. In cases in which I am worried about ptosis, I inject the frontalis close to the hairline. In order to reduce the risk of these unwanted effects, injections should be administered in the upper third of the forehead only. The needle should be inserted at a 45° angle superiorly. Because the frontalis is an elevator muscle, weakening can cause brow ptosis or exacerbate preexisting brow ptosis.
An injection of BOTOX is prepared by drawing into an appropriately sized sterile syringe an amount of the properly reconstituted toxin slightly greater than the intended dose. Air bubbles in the syringe barrel are expelled and the syringe is attached to an appropriate injection needle. Patency of the needle should be confirmed. A new, sterile needle and syringe should be used to enter the vial on each occasion for removal of BOTOX.
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.
Unopened vials of BOTOX should be stored in a refrigerator (2° to 8°C) for up to 36 months. Do not use after the expiration d ate on the vial. Administer BOTOX within 24 hours of reconstitution; during this period reconstituted BOTOX should be stored in a refrigerator (2° to 8°C). Reconstituted BOTOX should be clear, colorless, and free of particulate matter.
Cornea problems have been reported. Cornea (surface of the eye) problems have been reported in some people receiving BOTOX® for their blepharospasm, especially in people with certain nerve disorders. BOTOX® may cause the eyelids to blink less, which could lead to the surface of the eye being exposed to air more than is usual. Tell your doctor if you experience any problems with your eyes while receiving BOTOX®. Your doctor may treat your eyes with drops, ointments, contact lenses, or with an eye patch.
