In the case of Botox, doctors who experiment off-label say they do so because they're looking for better treatment options for their patients. "In my 30 years of medical practice, Botox is one of the most impactful treatments I had ever seen," says Dr. Linda Brubaker, dean and chief diversity officer of the Loyola University Chicago Stritch School of Medicine, who independently studied Botox for overactive bladder before the FDA approved it for that condition in 2013.
Therefore, it is important to remember that if a clinic or medical spa states that they are providing Botox at a certain dollar amount per unit, it is quite possible that they are diluting the Botox and actually not providing the agreed-upon amount. This is much like the concept of a watered-down drink at a bar, but the costs are much larger when it comes to Botox or its alternatives, Dysport and Xeomin.
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.
Botulism toxins are produced by bacteria of the genus Clostridium, namely Clostridium botulinum, C. butyricum, C. baratii and C. argentinense, which are widely distributed, including in soil and dust. As well, the bacteria can be found inside homes on floors, carpet, and countertops even after cleaning. Some food products such as honey can contain amounts of the bacteria.
Botulinum toxin exerts its effect by cleaving key proteins required for nerve activation. First, the toxin binds specifically to nerves which use the neurotransmitter acetylcholine. Once bound to the nerve terminal, the neuron takes up the toxin into a vesicle. As the vesicle moves farther into the cell, it acidifies, activating a portion of the toxin which triggers it to push across the vesicle membrane and into the cell cytoplasm. Once inside the cytoplasm, the toxin cleaves SNARE proteins preventing the cell from releasing vesicles of neurotransmitter. This stops nerve signaling, leading to paralysis.
Table 14 presents the most frequently reported adverse reactions in a placebo-controlled, double-blind post-approval 52 week study with BOTOX 100 Units (Study NDO-3) conducted in MS patients with urinary incontinence due to detrusor overactivity associated with a neurologic condition. These patients were not adequately managed with at least one anticholinergic agent and not catheterized at baseline. The table below presents the most frequently reported adverse reactions within 12 weeks of injection.
BTX-A is now a common treatment for muscles affected by the upper motor neuron syndrome (UMNS), such as cerebral palsy, for muscles with an impaired ability to effectively lengthen. Muscles affected by UMNS frequently are limited by weakness, loss of reciprocal inhibition, decreased movement control and hypertonicity (including spasticity). In January 2014, Botulinum toxin was approved by UK's Medicines and Healthcare Products Regulatory Agency (MHRA) for the treatment of ankle disability due to lower limb spasticity associated with stroke in adults. Joint motion may be restricted by severe muscle imbalance related to the syndrome, when some muscles are markedly hypertonic, and lack effective active lengthening. Injecting an overactive muscle to decrease its level of contraction can allow improved reciprocal motion, so improved ability to move and exercise.
Tell your doctor about all your medical conditions, including: plans to have surgery; had surgery on your face; have trouble raising your eyebrows; drooping eyelids; any other abnormal facial change; are pregnant or plan to become pregnant (it is not known if BOTOX® Cosmetic can harm your unborn baby); are breast-feeding or plan to (it is not known if BOTOX® Cosmetic passes into breast milk).
