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).
The correct way to inject Botox is to always customize the treatment plan to solve the aesthetic issues that bother the person. Some patients need only limited areas injected such as the vertical lines between their brows, their “crow’s feet” at the outer aspects of their eyelids, the “bunny” lines that radiate on the sides of their nose, vertical and horizontal lip lines and rarely patients request a correction of their “gummy” smile where their upper gums show when a person smile. Yes, you usually can pay for specific areas of treatment or by the number of units injected. But if you only want single line or area of your forehead injected you may not be satisfied with the results in the end. Why? -because when Botox or Dysport is injected it will weaken only the muscles that are treated, there may be muscles that were not treated that are pulling in an opposite direction that will produce undesirable results(an example of an undesirable effect occurs when treating just the glabella “11” lines between your eyebrows that may produce an overarched brow contour that resembles Mr. Spock.) Therefore, a complete treatment plan that includes all muscle groups should be treated to balance the pull and counter-pull of facial muscles.In addition, injections around the mouth must be performed by an experienced injector because there is the potential for the mouth to droop afterwards which can cause you to drool or may impact your ability to eat, pucker and smile. These adverse effect may last several weeks.
Of 1242 overactive bladder patients in placebo-controlled clinical studies of BOTOX, 41.4% (n=514) were 65 years of age or older, and 14.7% (n=182) were 75 years of age or older. Adverse reactions of UTI and urinary retention were more common in patients 65 years of age or older in both placebo and BOTOX groups compared to younger patients (see Table 18). Otherwise, there were no overall differences in the safety profile following BOTOX treatment between patients aged 65 years and older compared to youn ger patients in these studies.
Why Botox works isn’t completely clear. There’s some evidence that it may reduce the production of neurotransmitters related to pain in the areas where it’s injected. There’s also some evidence that it may have a broader effect on the brain’s pain centers, reducing the sensitivity that causes migraine sufferers to react to migraine triggers. While the exact mechanisms are poorly understood, the studies, as well as many of my patients’ experiences, do show a real benefit for many people.
"The difference between using a cannula and a 'needle injection' technique is cannulas are a blunt tip needle that lets us place filler on a plane that allows it to last longer," explains Goodman. "They look better and preserve the 'untouched look' we're known for. Also, it's a more advanced technique that ensures the patient will not leave the office bruised."
Think about it this way: people make facial expressions every single day, whether it's expressing an emotion (i.e. smiling) or simply out of habit (i.e. raising your brows). Making facial expressions causes temporary dynamic lines to show up in your face. These lines go away when your face returns to rest. However, as you continue to make facial expressions, day after day and year after year, and as your skin ages, these lines start to get etched in your skin. That's when frown lines get progressively deeper for people who frown all the time. Or when crow's feet stay put even after you stop smiling or squinting. Eventually, what once were dynamic wrinkles become wrinkles that are just there, even when you don't make any facial expressions.
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.'”
Botox is administered by injection and dosing depends on the condition that it is used for. Administration of botulinum toxin with other agents (for example, aminoglycosides, curare) that affect neuromuscular function may increase the effect of botulinum toxin. There are no adequate studies of Botox in pregnant women and it has not been evaluated in nursing mothers.
Safety and effectiveness of BOTOX have not been established for the treatment of other upper or lower limb muscle groups. Safety and effectiveness of BOTOX have not been established for the treatment of spasticity in pediatric patients under age 18 years. BOTOX has not been shown to improve upper extremity functional abilities, or range of motion at a joint affected by a fixed contracture. Treatment with BOTOX is not intended to substitute for usual standard of care rehabilitation regimens.
Side effects from therapeutic use can be much more varied depending on the location of injection and the dose of toxin injected. In general, side effects from therapeutic use can be more serious than those that arise during cosmetic use. These can arise from paralysis of critical muscle groups and can include arrhythmia, heart attack, and in some cases seizures, respiratory arrest, and death. Additionally, side effects which are common in cosmetic use are also common in therapeutic use, including trouble swallowing, muscle weakness, allergic reactions, and flu-like syndromes.
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).
