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).
In the mid-1990s, people who received BOTOX for other conditions reported improvement in their chronic migraine pain. A two-phase study was conducted, treating patients who averaged 20 headache days a month. They received BOTOX injections every twelve weeks for 56 weeks. At the end of that period, 70% of the patients had fewer than half the number of headaches they had before treatment. The FDA officially approved BOTOX to treat chronic migraine in October of 2010. Since then, more than 100,000 patients have been treated.

Botulinum toxin (BTX) is a neurotoxic protein produced by the bacterium Clostridium botulinum and related species.[1] It prevents the release of the neurotransmitter acetylcholine from axon endings at the neuromuscular junction and thus causes flaccid paralysis. Infection with the bacterium causes the disease botulism. The toxin is also used commercially in medicine, cosmetics and research.

In patients who are not catheterizing, post-void residual (PVR) urine volume should be assessed within 2 weeks post treatment and periodically as medically appropriate up to 12 weeks, particularly in patients with multiple sclerosis or diabetes mellitus. Depending on patient symptoms, institute catheterization if PVR urine volume exceeds 200 mL and continue until PVR falls below 200 mL. Instruct patients to contact their physician if they experience difficulty in voiding as catheterization may be required.
Study 3 compared 3 doses of BOTOX with placebo and enrolled 88 patients [BOTOX 360 Units (N=23), BOTOX 180 Units (N=23), BOTOX 90 Units (N=23), and placebo (N=19)] with upper limb spasticity (expanded Ashworth score of at least 2 for elbow flexor tone and at least 3 for wrist flexor tone and/or finger flexor tone) who were at least 6 weeks post -stroke. BOTOX and placebo were injected with EMG guidance into the flexor digitorum profundus, flexor digitorum sublimi s, flexor carpi radialis, flexor carpi ulnaris, and biceps brachii (see Table 27).
This product contains albumin, a derivative of human blood. Based on effective donor screening and product manufacturi ng processes, it carries an extremely remote risk for transmission of viral diseases. A theoretical risk for transmission of Creutzfeldt -Jakob disease (CJD) is also considered extremely remote. No cases of transmission of viral diseases or CJD have ever be en reported for albumin.

The range of prices for a single unit of Botox range between $10 and $20 per unit. But the total cost of Botox treatment depends on exactly what you're trying to achieve. For example, the cost of treating horizontal forehead lines may range anywhere from $300 to $700 depending on the factors mentioned above. For other facial areas you may need fewer units.
Over time, the muscles above and between the eyebrows repeatedly contract and tighten, causing wrinkles. Botox Cosmetic works beneath the skin’s surface and targets the underlying muscle activity that causes frown lines and crow’s feet to form over time. Normally when we squint, frown, or make other facial expressions, our nerves release a neurotransmitter chemical, known as acetylcholine. This neurotransmitter binds to receptors within the muscle to make it contract. Wrinkle relaxers like Botox and DYSPORT® work by binding to the acetylcholine receptors, and blocking the signal from the nerve to the muscles.
It can also be expensive. Depending on your insurance, it can cost quite a lot of money — I've changed insurance providers since I first started, and my first provider was around $330 a month and charged me around $1,000 per Botox round (remember, that's four times a year). My new plan is much more expensive, around $600 a month, but the Botox copay is only $30 each time, so even if Botox is the only medical procedure I need to have done in the year, it made sense to switch.
This imbalance can affect a joint in varied ways such as at the ankle with foot position (always points toes or up on toes when walking) or at the wrist with hand position (hand in flexion with problems grasping). After a contracture occurs (not able to bring the joint through its full range of motion, even with forceful / prolonged stretching) it can be hard to re-establish full range of motion at that joint without surgery.
Prevention of contractures begins with finding out what is limiting a child from either actively (moving oneself) or passively (being moved by someone else) moving the joints through a full range of motion. In some cases, this can be due to destruction or abnormality of the bones around a joint. It can also be due to problems with the ligaments and tissue around that joint.
Ophthalmologists specializing in eye muscle disorders (strabismus) had developed the method of EMG-guided injection (using the electromyogram, the electrical signal from an activated muscle, to guide injection) of local anesthetics as a diagnostic technique for evaluating an individual muscle’s contribution to an eye movement.[44] Because strabismus surgery frequently needed repeating, a search was undertaken for non-surgical, injection treatments using various anesthetics, alcohols, enzymes, enzyme blockers, and snake neurotoxins. Finally, inspired by Daniel Drachman’s work with chicks at Johns Hopkins,[45] Alan B Scott and colleagues injected botulinum toxin into monkey extraocular muscles.[46] The result was remarkable: a few picograms induced paralysis that was confined to the target muscle, long in duration, and without side-effects.
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.
Treatment with botulinum toxins may weaken neck muscles that serve as accessory muscles of ventilation. This may result in a critical loss of breathing capacity in patients with respiratory disorders who may have become dependent upon these accessory muscles. There have been postmarketing reports of serious breathing difficulties, including respiratory failure.
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.

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 was evaluated in two randomized, multi-center, 24-week, 2 injection cycle, placebo-controlled double-blind studies. Study 1 and Study 2 included chronic migraine adults who were not using any concurrent headache prophylaxis, and during a 28 -day baseline period had ≥15 headache days lasting 4 hours or more, with ≥50% being migraine/probable migraine. In both studies, patients were randomized to receive placebo or 155 Units to 195 Units BOTOX injections every 12 weeks for the 2-cycle, double-blind phase. Patients were allowed to use acute headache treatments during the study. BOTOX treatment demonstrated statistically significa nt and clinically meaningful improvements from baseline compared to placebo for key efficacy variables (see Table 24).
Serious adverse reactions, including excessive weakness, dysphagia, and aspiration pneumonia, with some adverse reactions associated with fatal outcomes, have been reported in patients who received BOTOX injections for unapproved uses. In these cases, the adverse reactions were not necessarily related to distant spread of toxin, but may have resulted from the administration of BOTOX to the site of injection and/or adjacent structures. In several of the cases, patients had pre-existing dysphagia or other significant disabilities. There is insufficient information to identify factors associated with an increased risk for adverse reactions a ssociated with the unapproved uses of BOTOX. The safety and effectiveness of BOTOX for unapproved uses have not been established.

One of the most beneficial uses of BOTOX\for migraines is that it can serve as an indicator of how effective migraine surgery might be for you. BOTOX stops contracting muscles from irritating triggering nerves. If that gives you relief, you may benefit from surgery to “free up” pressure on those nerves. Using BOTOX may also help identify which nerves could be triggering your migraines, making surgical intervention more targeted.

According to the PREEMPT injection paradigm, 5 units of onabotulinumtoxinA is to be administered to two sites on each side for a total dose of 20 units across four sites in the cervical paraspinal muscle group near the midline. The first injection site is approximately 1 cm left of the midline of the cervical spine and approximately 3 cm (2 fingerbreadths) inferior to the occipital protuberance. The second site is measured approximately 1 fingerbreadth diagonally up at a 45° angle from the first injection. The injections should be administered in the most superficial aspect of the muscle, angling the needle 45° and superiorly. To aid in the placement of the injections, the patient should be positioned upright with the head in a neutral position. If the neck is flexed too far forward, injections may be too deep. Injections that are too low or too deep in this muscle group can lead to muscle weakness and neck pain. Injectors should use a suboccipital approach to ensure that the injection sites are not too low. In addition, a horizontal line can be visualized across the neck, approximately 2 fingerbreadths down from the occipital protuberance, to make certain the injections remain above the line and are not administered too low in the neck. The higher these injections are, the more likely that they will be in the muscle fascial condensation, which will minimize the potential for neck weakness. These injections should not be done below the hairline. Patients who have trigger points in the neck should not be injected at these sites as these are generally areas where muscles may be weakened and injections of onabotulinumtoxinA at these sites might worsen their neck issues.


OnabotulinumtoxinA is the only treatment approved by the United States Food and Drug Administration for the prevention of headaches in adult patients with chronic migraine (CM). CM assessment involves a detailed history to rule out secondary sources of headache, establish migraine features, and assess the total number of headache days. In order to diagnose migraine, the patient should have had at least five attacks that involve migraine features, as outlined below. In adults, untreated attacks usually last 4 or more hours.
As with with plastic surgery or any other cosmetic procedure, what you are paying for is an injector who has experience and a proven track record of beautiful results. If you're looking for a precise estimate of what it will cost to achieve your Botox goals, I encourage you to meet with a board-certified plastic surgeon or dermatologist for an initial consultation.
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).
Aesthetician Mary Schook is anti-Botox because she sees the long-term effects on her clients. “Everyone is always like, ‘Look how great this looks,’ and then there is the long-term and they are like, 'Fix me,'” she says. “Allergan [the company that owns Botox] says one in 100 patients gets eyelid-drop, so I always joke, ‘I must meet one in 100 patients, because everyone I see has that drop.'”
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.

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.
There are eight types of botulinum toxin, named type A–H. Types A and B are capable of causing disease in humans, and are also used commercially and medically.[3] Types C–G are less common; types E and F can cause disease in humans, while the other types cause disease in other animals.[4] Type H is considered the deadliest substance in the world – an injection of only 2 ng can cause death to an adult.[5] Botulinum toxin types A and B are used in medicine to treat various muscle spasms and diseases characterized by overactive muscle. Commercial forms are marketed under the brand names Botox and Dysport, among others.[6][7]
In 1895 (seventy-five years later), Émile van Ermengem, professor of bacteriology and a student of Robert Koch, correctly described Clostridium botulinum as the bacterial source of the toxin. Thirty-four attendees at a funeral were poisoned by eating partially salted ham, an extract of which was found to cause botulism-like paralysis in laboratory animals. Van Ermengem isolated and grew the bacterium, and described its toxin,[40] which was later purified by P Tessmer Snipe and Hermann Sommer.[41]

The cosmetic effect of BTX-A on wrinkles was originally documented by a plastic surgeon from Sacramento, California, Richard Clark, and published in the journal Plastic and Reconstructive Surgery in 1989.[51] Canadian husband and wife ophthalmologist and dermatologist physicians, JD and JA Carruthers, were the first to publish a study on BTX-A for the treatment of glabellar frown lines in 1992.[52] Similar effects had reportedly been observed by a number of independent groups (Brin, and the Columbia University group under Monte Keen.[53]) After formal trials, on April 12, 2002, the FDA announced regulatory approval of botulinum toxin type A (Botox Cosmetic) to temporarily improve the appearance of moderate-to-severe frown lines between the eyebrows (glabellar lines).[54] Subsequently, cosmetic use of botulinum toxin type A has become widespread.[78] The results of Botox Cosmetic can last up to four months and may vary with each patient.[79] The US Food and Drug Administration approved an alternative product-safety testing method in response to increasing public concern that LD50 testing was required for each batch sold in the market.[55][56]
Even though the procedure seems easy, it is still a medical procedure and requires a trained professional to administer the Botox solution. The credentials and experience of the doctors are critical regardless how much does Botox cost in their shop. Remember that a legit procedure is much safer and guarantees the end result which directly protects your investment.
