The overall cost of  the injection is charged either at a flat rate or per unit. In terms of per unit, the overall cost of the treatment will depend on the total volume or a total number of units used in the procedure. But service charged at a flat rate depends on the area to be treated. The most expensive area is around the underarm for treating hyperhidrosis.
Proper refrigeration at temperatures below 3 °C (38 °F) retards the growth of Clostridium botulinum. The organism is also susceptible to high salt, high oxygen, and low pH levels.[citation needed] The toxin itself is rapidly destroyed by heat, such as in thorough cooking.[72] The spores that produce the toxin are heat-tolerant and will survive boiling water for an extended period of time.[73]

University-based ophthalmologists in the USA and Canada further refined the use of botulinum toxin as a therapeutic agent. By 1985, a scientific protocol of injection sites and dosage had been empirically determined for treatment of blepharospasm and strabismus.[76] Side effects in treatment of this condition were deemed to be rare, mild and treatable.[77] The beneficial effects of the injection lasted only 4–6 months. Thus, blepharospasm patients required re-injection two or three times a year.

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.
