Botox for excessive sweating (hyperhidrosis).

Excessive sweating that defies antiperspirants is a real medical condition called hyperhidrosis. Botox is FDA-approved for this — a single treatment can stop excessive underarm sweating for 6–9 months. Many patients describe it as the most life-changing treatment we offer.

How the treatment works

The mechanism — plain language.

Sweating is triggered by acetylcholine — a neurotransmitter released at the sweat gland. Botox blocks acetylcholine release in the treated area, effectively turning off the targeted sweat glands.

For underarm hyperhidrosis, we inject 50 units of Botox per side in a precise grid pattern, blocking sweat production for the entire underarm area.

For palmar (palm) or plantar (sole) hyperhidrosis, we use a topical numbing protocol and inject the same way. These areas are more sensitive but well-tolerated with proper numbing.

Effect begins within 7 days and is fully established by week 2. Sweating in the treated area is typically reduced 80–90%.

Clinical evidence

What the research shows.

Multiple FDA studies have shown a 75–85% reduction in sweating for patients receiving 50 units per underarm. Patient-reported quality of life scores improve dramatically. The effect lasts 6–9 months, and patients return for re-treatment.

Is this right for you?

Who qualifies.

  • Excessive sweating in underarms, palms, or soles that disrupts daily life
  • No relief from prescription-strength antiperspirants (typically aluminum chloride)
  • Symptoms onset typically before age 25
  • Symptoms present at least 6 months

Not the right approach if:

Generalized sweating (not focal) — this can indicate an underlying medical condition that needs investigation. Sweating that started recently with no clear pattern. Pregnancy or breastfeeding.

Common questions

What patients ask before starting.

How much does it cost?
For underarm hyperhidrosis, we use 100 units total (50 per side) at our standard per-unit rate. We give you the total at consult.
Is it covered by insurance?
Some insurance plans cover Botox for primary axillary hyperhidrosis when documented failure of prescription antiperspirants and significant quality-of-life impact. We can help you understand what your plan covers.
How long does it last?
6–9 months for most patients. Some get longer relief over time as the body becomes less reactive in the treated area.
Will I sweat more elsewhere to compensate?
A small number of patients report mild compensatory sweating in untreated areas. This is generally manageable. Significant compensatory sweating is rare with the focal treatment.
Does it work for hands and feet too?
Yes — and for many patients, hands are the area most affecting their daily life. Hand treatment is more involved (requires numbing) but effective. We have hand-specific protocols.
Will it affect my workout sweating?
No. The treatment specifically targets the treated area (underarms, palms, soles). Your body still cools itself via sweating elsewhere during exercise.
