Sweating is our body's natural response to an increase in body temperature and emotions like anxiety. Hyperhidrosis is the excessive production of sweat often occuring in the underarms, hands, and feet, and those suffering from it may feel embarassed about it in their daily lives. Botox  is the commercial name for type A botulinum toxin (onabotulinumtoxinA) produced by Allergan Laboritories. Dysport is the commercial name for type A botulinum toxin (abobotulinumtoxinA) produced by Galderma Laboritories. Both of these products are commonly used for and work excellently to treat excessive sweating in the underarms. Botox or Dysport injections are rarely used for hyperhidrosis in the hands and feet. The injections are effective, however they're quite painful in those regions, making their use rather difficult and not largely recommended. You are able to return to your usual daily activities immediately after treatment and side effects are virtually nonexistent. Results generally show up after 3-4 days post-treatment and the effects of the Botox or Dysport can last 6-12 months depending on the individual.
