Why Botox For Hyperhidrosis?

The possible reasons why botox is required for hyperhidrosis can be attributed to

  • Failure of topical anti-perspirants
  • Low confidence and resulting emotional and psychological burden due to constant sweating
  • Difficulty in performing day to day tasks

There are two main types of Botulinum toxins which are used in case of hyperhidrosis. They are

  • Botulinum toxin-A
  • Botulinum toxin-B

The most commonly used Botulinum toxin in treatment for hyperhidrosis is Botulinum toxin-A but in case when the patients fails to show any improvement in symptoms then Botulinum toxin-B can also be used.

The dosage for botox depends on the area treated.The dosage is as follows

Sr no Area to be treated Dosage
1 Underarms 40 to 50  Unit per underarm side
2 Palms 70 to 75 Unit  per palm

Soles of feet


100 to 125 Units per sole

Your cosmetic dermatologist will be the best to guide you on the dosage depending on the area that needs treatment.

The procedure for Botox injection is as follows

  • Your dermatologist first cleans and shaves the area in case of underarms where Botox is to be injected
  • Betadine solution is applied
  • Then starch powder is sprinkled
  • A very intense dark blue coloration shows a positive test for hyperhidrosis
  • The area is cleaned
  • The area is marked by sketch pen
  • 1 unit per marked area of Botox is injected

The results typically last for 6 to 8 months for Botox in case of hyperhidrosis.

Repeated injections can be needed after 8 months as required.
