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.
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).
Children do very well after having this procedure in our clinic and are not upset when they leave. We rarely use sedation. We use distraction and a quick injection method instead. In rare cases, localization of a muscle may be needed using an electromyograph (EMG) machine or electric stimulator. If this is needed we will discuss this before scheduling the injections.
When moving a spastic limb through its range of motion, one feels a resistance to movement that increases with the speed at which one moves the limb. This is the definition of spasticity, but other terms such as increased muscle tone, hypertonicity, spastic dystonia, or flexor / extensor spasms are used to describe this resistance. In clinic the term "muscle spasticity" will be used to reduce confusion of terms.
Reduced blinking from BOTOX injection of the orbicularis muscle can lead to corneal exposure, persistent epithelial defect, and corneal ulceration, especially in patients with VII nerve disorders. Vigorous treatment of any epithelial defect should be employed. This may require protective drops, ointment, therapeutic soft contact lenses, or closure of the eye by patching or other me ans.
Firstly, that is one of the most popular combination of areas for Botox treatment in my office. Like others on this panel, I happen to think the fairest method for charging for Botox is by the unit. Botox can only be purchased through Allergan here in the United States and comes in a 100 unit bottle typically. The only common denominator between offices is how many units of Botox are you...

The bacterium can also be found in the intestinal tracts of mammals and fish and in the gills and organs of crabs and other shellfish. Such naturally occurring instances of Clostridium botulinum bacteria and spores are generally harmless. Problems only arise when the spores transform into vegetative cells and the cell population increases. At a certain point, the bacteria begin producing botulinum toxin, the deadly neurotoxin responsible for botulism.

Botulinum toxin has been investigated for use in patients with blepharospasm in several studies. In an open label, historical ly controlled study, 27 patients with essential blepharospasm were injected with 2 Units of BOTOX at each of six sites on each side. Twenty-five of the 27 patients treated with botulinum toxin reported improvement within 48 hours. One patient was controlled with a higher dosage at 13 weeks post initial injection and one patient reported mild improvement but remained functionally impaired.


When my babies were little, I never discussed migraine with them. As they grew into preschool and elementary age, I found it necessary to explain it to them.  They had seen me experience migraine symptoms for a long time but understood it as just being sick. We went to a migraine walk where we talked about how others cope like I do, and they heard other stories that were similar to mine. They felt empowered that we had fundraised for a disease that affects millions and that we were fighting it as a family and community. My children want to help. Having ways they can help builds their confidence in their ability to take care of me, as I do them. They know to turn the lights off, get ice and talk quietly. I have taught them how to be self-sufficient. I’m so proud of how they take care of themselves and are willing to take care of others. The qualities that they’re learning and displaying will carry them through life.


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.
At the recent American Headache Society meeting in Washington DC, Allergan invested heavily in educating the board-certified headache physicians on the most effective injection sites and methods for Chronic Migraine patients. Find one here. Were I to repeat Botox for Migraine, I would absolutely find one of those Allergan-trained doctors and ask them exactly how many Botox for Migraine procedures they’d done.
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).
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:
In both studies, significant improvements compared to placebo in the primary efficacy variable of change from baseline in wee kly frequency of incontinence episodes were observed for BOTOX (200 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 we re also observed. These primary and secondary endpoints are shown in Tables 21 and 22, and Figures 7 and 8.
In cosmetic applications, botulinum toxin is considered safe and effective for reduction of facial wrinkles, especially in the uppermost third of the face.[23] Injection of botulinum toxin into the muscles under facial wrinkles causes relaxation of those muscles, resulting in the smoothing of the overlying skin.[23] Smoothing of wrinkles is usually visible three days after treatment and is maximally visible two weeks following injection.[23] The treated muscles gradually regain function, and generally return to their former appearance three to four months after treatment.[23] Muscles can be treated repeatedly to maintain the smoothed appearance.[23]
BOTOX may be an effective treatment for those who suffer from chronic migraines. Many patients have struggled to find a treatment that truly provides relief from this debilitating condition. While there are migraine medications and a host of natural remedies, for many people, none of these methods bring real relief. BOTOX may be the option that brings the relief from pain that patients have been seeking for so long.
As you noted in your question, the effects of Botox don't last forever. For some patients the short term effects of Botox are a ‘good thing,’ as it means that trying Botox is a relatively low risk/low commitment procedure. If you don't like your Botox results, there's not much to worry about: They will fade on their own in a few months. Generally speaking, the results last between three to five months -- but the duration of the Botox effect depends on the individual and on how many Botox units were used.

The procerus is a small triangular-shaped muscle that intermingles with the inferior aspect of the frontalis muscle. The muscle runs from the aponeurotic fascia on the nasal bones and inserts into the skin of the inferior forehead. The medial portion of the eyebrow and the skin of the lower forehead are drawn down by the procerus muscle, producing transverse wrinkle lines over the bridge of the nose.

The results showed that 34% of those who responded and tried Botox said it significantly helped them. Sixteen percent reported a slight benefit. Nine percent stated that it didn’t help at all. Eleven percent stated that they would like to try Botox but it is too expensive. About 10% said they had no plans to try Botox, and 18% said they hadn’t tried it yet.


If you undergo Botox treatments for migraines, your doctor will typically administer them once every three months. Depending on your response to Botox, your doctor will recommend a length of time for your treatment plan. Each session will last between 10 and 15 minutes. During the sessions, your doctor will inject multiple doses of the medicine into specific points along the bridge of your nose, your temples, your forehead, the back of your head, your neck, and your upper back.
It is not known whether BOTOX® is safe or effective to treat increased stiffness in upper limb muscles other than those in the elbow, wrist, fingers, and thumb, or in lower limb muscles other than those in the ankle and toes. BOTOX® has not been shown to help people perform task-specific functions with their upper limbs or increase movement in joints that are permanently fixed in position by stiff muscles. Treatment with BOTOX® is not meant to replace existing physical therapy or other rehabilitation that may have been prescribed.
