The seven toxin types (A-G) have different tertiary structures and sequence differences. While the different toxin types all target members of the SNARE family, different toxin types target different SNARE family members. The A, B, and E serotypes cause human botulism, with the activities of types A and B enduring longest in vivo (from several weeks to months).
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).
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.
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.
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.
Costs to consider: immediate out-of-pocket costs, long-term higher cost of insurance, your time, and the pain of injections. Botox for migraine costs approximately $525 per vial (100 units) and a typical migraine dose is 155 units. Depending on what your doctor charges in addition to the Botox itself, it’ll set you back $1500 – $2300 to test it out. And then there’s the needle pain. Don’t make the mistake of going to get a Botox injection if you’re in the midst of an attack, because it’ll be more painful than ever. Better to reschedule.
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.
Two double-blind, placebo-controlled, randomized, multi-center, 24-week clinical studies were conducted in patients with OAB with symptoms of urge urinary incontinence, urgency, and frequency (Studies OAB -1 and OAB-2). Patients needed to have at least 3 urinary urgency incontinence episodes and at least 24 micturitions in 3 days to enter the studies. A total of 1105 patients, whose symptoms had not been adequately managed with anticholinergic therapy (inadequate response or intolerable side effects), were randomized to receive either 100 Units of BOTOX (n=557), or placebo (n=548). Patients received 20 injections of study drug (5 units of BOTOX or placebo) spaced approximately 1 cm apart into the detrusor muscle.
Dr. Matarasso says hardly a week goes by when he doesn’t see a patient with a botched Botox job. Why? People are getting it done by unexperienced, often unlicensed, practitioners who don’t know the shape of the face and how to correctly administer the toxin. “I just had a patient come in the other day who went to an ER doctor, and one that went to a psychiatrist,” he says. “They [also] have these Botox parties and I have seen scarring, significant bruising, not only functional, but aesthetic complications.”
* LS mean change, treatment difference and p-value are based on an analysis using an ANCOVA model with baseline weekly endpoint as covariate and treatment group, etiology at study entry (spinal cord injury or multiple sclerosis), concurrent anticholinergic therapy at screening, and investigator as factors. LOCF values were used to analyze the primary efficacy variable.
Once the protein stops functioning at the neuromuscular junction, it is broken down into its harmless components (amino acids) and either recycled for use in other proteins or excreted by the kidneys. "The bigger the muscle, the quicker you'll see motion return," says Rowe. "Likewise, the smaller the muscle, the longer the effect of botox lasts." It doesn't have a tolerance effect, either—your body never gets used to Botox.
Dermal fillers, as we’ve discussed in our previous post, vary on what you’re looking for and how long you’d like to see those results. According to the Plastic Surgeons Portal, the minimum you’ll pay for dermal fillers, like Juvederm and Restylane, is going to $1500, while the maximum you’re looking at is $2,500. It’s a small price to pay for radiance and confidence!
How Was the Botox Mixed? A factor that many patients are unaware of is that Botox and Dysport come in a powder form that must be mixed with sterile saline to reconstitute the vial. The amount of water that is mixed with the Botox or Dysport can vary and will determine the concentration of the medicine. Some doctors and nurses dilute the powder too much so that the final concentration of Botox or Dysport is weak. So if you go to a provider who advertises a cheap price (for instance below the wholesale price) the injections you may be getting may be very dilute and may not be as effective as a more concentrated (more expensive) injection.
Exploratory analyses of this study suggested that the majority of patients who had shown a beneficial response by week 6 had returned to their baseline status by 3 months after treatment. Exploratory analyses of subsets by patient sex and age suggest that both sexes receive benefit, although female patients may receive somewhat greater amounts than male patients. There is a consistent trea tmentassociated effect between subsets greater than and less than age 65. There were too few non-Caucasian patients enrolled to draw any conclusions regarding relative efficacy in racial subsets.
Our advice: if you’re going to try it, don’t give up on Botox for Migraine after the first try, and reconsider whether you’re a good candidate after three tries. Both Drs. Jackson and Kornel noted that there was a large placebo effect seen in many of the studies. “It’s hard to know if most of the benefit was from the drug or from the placebo effect,” said Jackson, who added, “but, patients don’t care if it’s a placebo effect.”
Autonomic dysreflexia in patients treated for overactive bladder due to neurologic disease. Autonomic dysreflexia associated with intradetrusor injections of BOTOX® could occur in patients treated for detrusor overactivity associated with a neurologic condition and may require prompt medical therapy. In clinical trials, the incidence of autonomic dysreflexia was greater in patients treated with BOTOX® 200 Units compared with placebo (1.5% versus 0.4%, respectively).
