The more areas that need treatment the higher the cost of treatment. The reason is also simple – the 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. A second 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 determines the concentration of the medicine. Some doctors and nurses dilute the powder too much so that the concentration of Botox or Dysport is weak. So if you go to a provider who advertises a cheap price for injections you should question whether or not you are receiving a very dilute injection.This dilute mixture typically does not produce the same effect as a more or not concentrated (more expensive) injection and does not last as long.

Botulism toxins are produced by bacteria of the genus Clostridium, namely Clostridium botulinum, C. butyricum, C. baratii and C. argentinense,[70] 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.[citation needed] Some food products such as honey can contain amounts of the bacteria.[citation needed]
Key secondary endpoints included Physician Global Assessment, finger flexors muscle tone, and thumb flexors tone at Week 6. The Physician Global Assessment evaluated the response to treatment in terms of how the patient was doing in his/her life using a scale from -4 = very marked worsening to +4 = very marked improvement. Study 1 results on the primary endpoint and the key secondary endpoints are shown in Table 26.
Allergan says Botox is well established as a drug and that the benefits and risks of toxins are well understood. "With more than 25 years of real-world clinical experience ... approximately 3,200 articles in scientific and medical journals, marketing authorizations in more than 90 markets and many different indications, Botox and Botox Cosmetic are [among] the most widely researched medicines in the world," an Allergan rep wrote in an emailed statement.

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.
