It will not affect the nerves that cause sensation, or make you feel numb. When it is used correctly, it can lift the brow to give an appealing and sincere look. "But if too much is injected in the danger zone—the horizontal lines in the forehead—you can look Spocked, as in Spock from Star Trek," says Jean Carruthers, a Vancouver eye surgeon who, with her husband, Alastair, coauthored the first paper on the cosmetic benefits of Botox in 1989. That's why it's important to be treated by an experienced doctor who can judge the size of your muscles and how much Botox you will need.
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.

In the event of overdose, antitoxin raised against botulinum toxin is available from the Centers for Disease Control and Preventio n (CDC) in Atlanta, GA. However, the antitoxin will not reverse any botulinum toxin-induced effects already apparent by the time of antitoxin administration. In the event of suspected or actual cases of botulinum toxin poisoning, please contact your local o r state Health Department to process a request for antitoxin through the CDC. If you do not receive a response within 30 minutes, please contact the CDC directly at 1-770-488-7100. More information can be obtained at http://www.cdc.gov/mmwr/preview/mmwrhtml/mm5232a8.htm.
Other side effects of BOTOX® and BOTOX® Cosmetic include: dry mouth, discomfort or pain at injection site, tiredness, headache, neck pain, eye problems: double vision, blurred vision, decreased eyesight, drooping eyelids, swelling of eyelids, dry eyes, and drooping eyebrows. In people being treated for urinary incontinence other side effects include: urinary tract infection, painful urination, and/or inability to empty your bladder on your own. If you have difficulty fully emptying your bladder after receiving BOTOX®, you may need to use disposable self-catheters to empty your bladder up to a few times each day until your bladder is able to start emptying again.
Exactly how soon you'll need to return for more Botox injections is really up to you. Some patients prefer to return for a touch up of Botox cosmetic after just three months, or at the very first sign of fine lines and facial wrinkles returning. Others prefer to wait six months or more until the effects of the previous injection have completely faded away.
Chapman and Bomba-Warczak both think Botox is safe when used correctly, but they say their inboxes quickly filled with messages after their study was published. "We were startled by the number of people who feel they were harmed by these toxins," says Chapman. "We feel these were pretty safe agents. Now it seems that for some people, they believe the toxin can sometimes cause something that may be irreversible. And that's a total mystery."

What Other Factors Determine the Cost of Botox? The fixed cost of Botox or Dysport that the doctor pays for the drugs is relatively expensive and therefore that cost is obviously passed along to the patient. The cost of Botox or Dysport injections also depends upon the number of areas that are required to obtain the best results. The more areas that need treatment the greater the amount of injections that will be required to arrive at the most desirable result. Simply put -the more areas that need  treatment the higher the cost of treatment.
BOTOX® treats the symptoms of severe underarm sweating when topical medicines do not work well enough in people 18 years and older. It is not known whether BOTOX® is safe or effective for severe sweating anywhere other than your armpits. BOTOX® treatments temporarily block the chemical signals from the nerves that stimulate the sweat glands, resulting in reduced sweating.
