Though there's still more research to be done on Botox for migraines and doctors aren't yet completely sure why the procedure is effective, they have some ideas. Ravitz tells me, "What [Botox] does is paralyze nerve terminals. Essentially, nerve terminals transmit pain, but they also produce pain substances while they’re doing that, and it completely paralyzes that process." She says that it stops the process of pain patterning and it also relaxes the muscles.
Tell your doctor about all your medical conditions, including if you: have or have had bleeding problems; have plans to have surgery; had surgery on your face; weakness of forehead muscles; trouble raising your eyebrows; drooping eyelids; any other abnormal facial change; have symptoms of a urinary tract infection (UTI) and are being treated for urinary incontinence (symptoms of a urinary tract infection may include pain or burning with urination, frequent urination, or fever); have problems emptying your bladder on your own and are being treated for urinary incontinence; are pregnant or plan to become pregnant (it is not known if BOTOX® or BOTOX® Cosmetic can harm your unborn baby); are breastfeeding or plan to (it is not known if BOTOX® or BOTOX® Cosmetic passes into breast milk).
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.
The frontalis muscle attaches to the skin of the lower forehead and ascends to join the fronto-occipital aponeurosis. The action of the frontalis muscle involves elevation of the eyebrows to produce expressions such as surprise, and can cause deep transverse wrinkles on the forehead. The antagonists for brow depression are the corrugators, procerus, and orbicularis oculi muscles.
In 1998, David E.I. Pyott became CEO of Allergan. He was enthusiastic about Botox's wrinkle-reducing potential, he says, and pushed the company to conduct a series of studies on the matter. In 2002, Botox earned FDA approval for so-called frown lines--wrinkles between eyebrows--marking the first time a pharmaceutical drug was given the green light for a strictly cosmetic purpose. In 2001, the year before Botox was approved for wrinkles, it generated about $310 million in sales. By 2013, the year it was approved for overactive bladder, Allergan reported nearly $2 billion in revenue from Botox.
Allergan’s Phase 3 hypothesis for securing conditional accelerated approval is to demonstrate that CVC treatment therapeutically initiates and induces improvement in histological hepatic fibrosis without worsening of NASH resolution. Notably, establishing improvement in NASH resolution after CVC therapy in NASH is not a prerequisite for attaining FDA conditional accelerated approval. A Phase 3 interim data readout for FDA Subpart H conditional accelerated approval is anticipated possibly in H1/2019.
In double-blind, placebo-controlled chronic migraine efficacy trials (Study 1 and Study 2), the discontinuation rate was 12% in the BOTOX treated group and 10% in the placebo-treated group. Discontinuations due to an adverse event were 4% in the BOTOX group and 1% in the placebo group. The most frequent adverse events leading to discontinuation in the BOTOX group were neck pain, headache, worsening migraine, muscular weakness and eyelid ptosis.
"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."
The effects of botulinum toxin are different from those of nerve agents involved insofar in that botulism symptoms develop relatively slowly (over several days), while nerve agent effects are generally much more rapid and can be instantaneous. Evidence suggests that nerve exposure (simulated by injection of atropine and pralidoxime) will increase mortality by enhancing botulinum toxin's mechanism of toxicity.
Just like any medical procedure the Botox treatment rarely comes with a few possible side-effects that are temporary. The frequency of complications generally decreases the more knowledge of facial anatomy that your injector possesses and the greater the experience of knowing where and how much to inject.That is not to say that complications can occur in anyones hands but the incidence decreases with greater experience.Allergic reactions to Botox or Dysport is exceedingly rare in my experience.
There are many physicians who encourage their patients to either work the area several times during the next several days or, alternatively, to not use the affected muscles during the next several days. Many practitioners do not tell the patients to do anything in particular other than to avoid strenuous activity for several hours afterward because of an increased risk of bruising.
As the only Facial Plastic Surgeon in North Texas to have Diamond status with Allergan, we have found that in today's economic environment, patients want value as well as quality. Understand that when you go to a non-physician med-spa for injectible treatments, there are more hands in the "cookie jar" diluting the price for your treatment. For example, the med-spa that is owned by a non-physician, with a nurse injector, is the hardest model to stay competitive in today's world. In that scenario, the patient is paying for the cost of the Botox; PLUS the cost of the nurse to inject the product; PLUS the fee for the medical director to sign off on the nurse doing the injections; AND the profit for the medspa. By going to a physician, the patient can cut out 2 of the middle-people. The chances of getting more product for the same price is greater by going to a doctor's office for your treatment.
If going back for additional treatments three or four times a year sounds like a lot of treatments, the good news is that the more Botox treatments you get, the fewer Botox units you'll need. With each repeat Botox session, the frontalis muscle and other facial muscles surrounding Botox injection sites get a little weaker and become "trained" to not contract.
There are no studies or adequate data from postmarketing surveillance on the developmental risk associated with use of BOTOX in pregnant women. In animal studies, administration of BOTOX during pregnancy resulted in adverse effects on fetal growth (decreased fetal weight and skeletal ossification) at clinically relevant doses, which were associated with maternal toxicity [see Data)].
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.
Botox comes as a crystalline substance from the manufacturer, which then has to be reconstituted with saline or another liquid. Practitioners add varying amounts of liquid when reconstituting it. Although there is no right or wrong amount of liquid to add, most physicians add about 2 mL-3 mL (about a half a teaspoon) of liquid to each vial. Some add quite a bit more, which can lead patients to think they are getting more Botox when, in reality, they are getting the same or less amount of Botox than samples reconstituted in a stronger way. It is the total dose of medication, not the volume of liquid, that leads to the desired effect.
Botox stays only where injected, it does not roam through the body. "If I inject it in your face, it's not going to work [or show up in] your toe," says Rowe. "It does not have a systemic effect." However, it may migrate up to 3 cm from where it was injected. But even if some molecules were to go into the bloodstream and travel to distant sites in the body, the cosmetic doses (typically less than 100 units) used are significantly lower than the toxic dose that would be harmful systemically (2,500-3,000 units).
