Neuromodulators for Excessive Sweating

Neuromodulators – injections of botulinum toxin commercially known as Botox and Dysport and Xeomin – can be used to treat excessive sweating. A minute amount of the neuromodulator is injected beneath the skin, where it is absorbed by nerve cells. It works by blocking neurotransmitters that encourage sweating. A typical treatment involves about 15 to 20 injections.

Possible risks

  • Soreness
  • Mild bruising
  • Temporary weakness of surrounding muscles
  • Headache

Why choose neuromodulators for excessive sweating

  • Can be used to treat underarms, palms and feet.
  • Non-invasive - does not require surgery.
  • Can be quickly performed in a doctor's office.
  • Virtually no recovery time.

What to expect after the procedure

  • A decrease in sweating within about two weeks.
  • The reduction lasts for about six months, so most patients will need to be treated twice per year.
  • Virtually no recovery time is required.
  • Patients should take care not to rub treated areas, which could cause it to migrate to another area.

How to prepare for the procedure

Before the procedure, an ASDS dermatologist will review the patient's medical history. This is the time for the doctor and patient to discuss expectations, potential risks and outcomes of the procedure. Patients should tell their doctor if they use, have recently taken or have had:

  • Blood thinning drugs
  • Previous neuromodulator therapy
  • Antibiotics by injection
  • Muscle relaxants
  • Allergy or cold medicine
  • Sleep medicine
