Unlike some resurfacing or surgical procedures, after which there is possible pigmentation or scarring, when Botox is done correctly, it can be done on all skin tones. “This is a procedure [and] product that crosses all divides,” says Dr. Matarasso. “Men, women, Caucasian, African-American, Asian, Indian. I don’t think there is a demographic that has not enjoyed the benefit of this product.”
The FDA approval was based on a large study showing that Botox significantly reduced migraine frequency and severity, as well as headache-related disability, compared to placebo. As just one measure of its effectiveness, many of my patients report that they’ve cut their use of rescue medications in half since starting Botox – a significant benefit for people who previously had to resort to rescue medications 15 or more times every month.

Results can vary depending on who is performing the injection on the patient. It is very important to go to a physician who is experienced at this procedure, does it him- or herself (rather than having a nurse, physician's assistant [PA], or other nonphysician do it), and has a good reputation for performing this type of procedure. The manufacturers of Botox recommend physicians inject the medication themselves. As with most procedures, the skill of the practitioner is related to how often he or she performs the procedure.

Botox has also been shown to prevent chronic migraines, but there, it's unclear exactly why Botox works. (For doctors, reaching a firm understanding of how Botox prevents migraines will be tricky, since they don't know for certain what causes the severe headaches in the first place.) "There were multiple clinical trials for migraines, and most of them failed," says Dr. Mitchell Brin, senior vice president of drug development at Allergan and chief scientific officer for Botox. "It took a long time to figure out where to inject and how much." Today people who receive Botox for migraine prevention get 31 injections in different spots on their head and neck. The effects of Botox can last about three to six months depending on the condition.
In general, the initial effect of the injections is seen within three days and reaches a peak at one to two weeks post-treatment. Each treatment lasts approximately three months, following which the procedure can be repeated. At repeat treatment sessions, the dose may be increased up to two-fold if the response from the initial treatment is considered insufficient, usually defined as an effect that does not last longer than two months. However, there appears to be little benefit obtainable from injecting more than 5 Units per site. Some tolerance may be found when BOTOX is used in treating blepharospasm if treatments are given any more frequently than every three months, and is rare to have the effect be permanent.

The idea of a needle going toward your forehead, in between your eyes, or at your eyebrows might be a little daunting, but rest assured, not only is Botox FDA-approved, but it’s a very common (and highly-requested) procedure. It’s commonly used for cosmetic reasons, but it also helps alleviate a slew of other health concerns.”Botox was first approved by the FDA in 1989 to treat blepharospasm of the eyelid, and now can treat hundreds of medical conditions, such as hyperhidrosis (excessive sweating) or chronic migraines,” dermatologist Jill S. Waibel, MD. She also notes that it was only approved for cosmetic purposes in 2002. “Since then, millions of people have had Botox done safely and effectively. It is important to remember that Botox is safest when used by a board certified dermatologist or a plastic surgeon.”


Botulinum toxin is one of the most poisonous substances known to man. Scientists have estimated that a single gram could kill as many as 1 million people and a couple of kilograms could kill every human on earth. In high concentrations, botulinum toxin can result in botulism, a severe, life-threatening illness. Botulism, left untreated, may result in respiratory failure and death. Despite botulinum toxin being so toxic, Botox is in huge demand.

García Leiva specified that this treatment "is not a first-choice treatment for migraine sufferers, but it can only be applied in patients with chronic migraine who have tried several treatments with poor results, and who show peripheral sensitization of muscles. Recently, the Foods and Drugs Administration (USA) has approved botulinum toxin as a therapeutical drug for the treatment of chronic migraine.
Botulinum toxin is a purified substance that's derived from bacteria. Injections of botulinum toxin block the nerve signals to the muscle in which it was injected. Without a signal, the muscle is not able to contract. The end result is diminished unwanted facial wrinkles or appearance. Commonly known types of botulinum toxin type A injections include Botox®, Dysport® and Xeomin®.
BOTOX® is the brand name of a toxin produced by the bacterium Clostridium botulinum. In large amounts, this toxin can cause a form of muscle paralysis known as botulism, which is usually associated with food poisoning. Even though one of the most serious complications of botulism is paralysis, scientists have discovered a way to use it to human advantage. Small, diluted (weakened) amounts can be directly injected into specific muscles, causing controlled relaxation of the muscles.

Since Botox made its first appearance in the med-spa world, a number of similar treatments have also become available. These include Dysport, another Botulinum toxin type A injectable, as well as dermal fillers (which use hyaluronic acid to plump skin) such as Juvéderm, Restylane, and Perlane. The decision to choose between Botox vs Dysport depends largely on the results you're hoping to achieve. For more information, check out the following guides:
Vials of BOTOX have a holographic film on the vial label that contains the name “Allergan” within horizontal lines of rainbow color. In order to see the hologram, rotate the vial back and forth between your fin gers under a desk lamp or fluorescent light source. (Note: the holographic film on the label is absent in the date/lot area.) If you do not see the lines of rainbow color or the name “Allergan”, do not use the product and contact Allergan for additional information at 1-800-890-4345 from 7:00 AM to 3:00 PM Pacific Time.
Botox was introduced to the world in the late 1980s by ophthalmologists, who began using it to treat optic muscle disorders. It was approved by the Food and Drug Administration (FDA) for the treatment of moderate to severe frown lines between the eyebrows (glabellar lines) in 2002, and its popularity has soared ever since. Botox is consistently one of the top five nonsurgical cosmetic procedures performed each year.
Other treatment areas that have been proven to be useful include the scalp (for migraine headaches), neck, facial and peripheral muscles (for spasms), arm pits (to inhibit sweating), the bladder and numerous other areas. The way that Botox and Dysport work is that they temporarily inhibit muscle contraction beneath the skin. When underlying muscles are relaxed the overlying folds and wrinkles are smoothed out. These injections work only by weakening underlying muscle contraction are not facial fillers like Restylane or Juvederm. Fillers and Botox or Dysport injections are not interchangeable. These injections work only by weakening underlying muscle contraction are not facial fillers like Restylane or Juvederm. Fillers are not interchangeable with Botox or Dysport injections. Fillers replace or “fill-in” lost facial volume whereas Botox or Dysport only inhibit muscle contraction.Both treatments are in fact complimentary aesthetic injections that will relax wrinkles and folds and help you regain your youthful appearance and enhance your face.

This imbalance can affect a joint in varied ways such as at the ankle with foot position (always points toes or up on toes when walking) or at the wrist with hand position (hand in flexion with problems grasping). After a contracture occurs (not able to bring the joint through its full range of motion, even with forceful / prolonged stretching) it can be hard to re-establish full range of motion at that joint without surgery.
Besides the three primary U.S. manufacturers, there are numerous other botulinum toxin producers. Xeomin, manufactured in Germany by Merz, is also available for both therapeutic and cosmetic use in the U.S.[67] Lanzhou Institute of Biological Products in China manufactures a BTX-A product; as of 2014 it was the only BTX-A approved in China.[67] BTX-A is also sold as Lantox and Prosigne on the global market.[68] Neuronox, a BTX-A product, was introduced by Medy-Tox Inc. of South Korea in 2009;[69]
Serious and/or immediate hypersensitivity reactions have been reported. These reactions include anaphylaxis, serum sickness, urticaria, soft-tissue edema, and dyspnea. If such reactions occur, further injection of BOTOX® Cosmetic should be discontinued and appropriate medical therapy immediately instituted. One fatal case of anaphylaxis has been reported in which lidocaine was used as the diluent and, consequently, the causal agent cannot be reliably determined.
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.
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.
The recommended dilution is 200 Units/4 mL or 100 Units/2 mL with preservative -free 0.9% Sodium Chloride Injection, USP (see Table 1). The lowest recommended starting dose should be used, and no more than 50 Units p er site should generally be administered. An appropriately sized needle (e.g., 25-30 gauge) may be used for superficial muscles, and a longer 22 gauge needle may be used for deeper musculature. Localization of the involved muscles with techniques such as needle electromyographic guidance or nerve stimulation is recommended.
A double-blind, placebo-controlled study enrolled patients who had extended histories of receiving and tolerating BOTOX injections, with prior individualized adjustment of dose. The mean BOTOX dose administered to patients in this study was 236 Units (25th to 75th percentile range of 198 Units to 300 Units). The BOTOX dose was divided among the affected muscles [see Clinical Studies].

BOTOX increases the incidence of urinary tract infection [see ADVERSE REACTIONS]. Clinical trials for overactive bladder excluded patients with more than 2 UTIs in the past 6 months and those taking antibiotics chronically due to recurrent UTIs. Use of BOTOX for the treatment of overactive bladder in such patients and in patients with multiple recurrent UTIs during t reatment should only be considered when the benefit is likely to outweigh the potential risk.


Three percent of patients experienced eyelid drooping in the frown lines studies, one percent of patients experienced eyelid swelling in the crow's feet studies, and one percent of patients experienced brow drooping in the forehead lines studies. Other possible side effects include: dry mouth; discomfort or pain at the injection site; tiredness; headache; neck pain; eye problems: double vision, blurred vision, decreased eyesight and dry eyes; and allergic reactions. These are not all of the possible serious side effects of BOTOX® Cosmetic. Please see the Important Safety Information including Boxed Warning and Medication Guide and talk to your specialist.
In some practices, the cost of the actual product determines the price, but in others, "The cost of the treatment is based on the skill set, not the product," says Day. In other words, seeing a trained aesthetic physician, who has the time and technique to give you tailored, micro injections, might actually be more costly than larger, more formulaic doses.
Andrew M. Blumenfeld is director of The Headache Center of Southern California. Most of his research has focused on the use of OnabotulinumtoxinA in the treatment of chronic migraine. He helped develop the injection paradigm approved by the United States Food and Drug Administration and has taught providers around the world on practical aspects of this treatment option.

“Most people in their twenties decide to try Botox simply because they want to enhance their appearance, such as relaxing the muscles in their forehead, or because they want to keep their skin looking fresh and young,” Shah says. “Starting earlier is better than later because as the lines get more and more embedded into the skin, Botox is not as effective in eliminating the lines.”
After the injections, the patient will usually lay upright or semiupright on the exam table for about two to five minutes to make sure he or she feels good after the procedure, and then the patient should avoid lying down for two to four hours. If bruising is a concern, it will be important for the patient to avoid taking aspirin or related products, such as ibuprofen (Advil, Motrin) or naproxen (Aleve), if possible after the procedure to keep bruising to a minimum.

In both studies, significant improvements compared to placebo in the primary efficacy variable of change from baseline in wee kly frequency of incontinence episodes were observed for BOTOX (200 Units) at the primary efficacy time point at week 6. Increases in maximum cystometric capacity and reductions in maximum detrusor pressure during the first involuntary detrusor contraction we re also observed. These primary and secondary endpoints are shown in Tables 21 and 22, and Figures 7 and 8.
Symptoms of overdose are likely not to be present immediately following injection. Should accidental injection or oral ingest ion occur or overdose be suspected, the person should be medically supervised for several weeks for signs and symptoms of systemic muscular weakness which could be local, or distant from the site of injection [see BOX WARNING and WARNINGS AND PRECAUTIONS]. These patients should be considered for further medical evaluation and appropriate medical therapy immediately instituted, which may include hospitalization.

When BOTOX (4, 8, or 16 Units/kg) was administered intramuscularly to pregnant mice or rats two times during the period of organogenesis (on gestation days 5 and 13), reductions in fetal body weight and decreased fetal skeletal ossification were ob served at the two highest doses. The no-effect dose for developmental toxicity in these studies (4 Units/kg) is approximately equal to the human dose of 400 Units, on a body weight basis (Units/kg).
Can you use Botox under your eyes? Botox is often used to treat lines and wrinkles around the eyes and mouth. Can it also reduce dark circles or bags under the eyes? Using Botox under the eyes is not approved in the U.S. and researchers are unsure how well it may work and what side effects may occur. Here, learn about the procedure and its alternatives. Read now
