Hyperhidrosis

Hyperhidrosis is a medical condition characterized by excessive sweating beyond what's needed for temperature regulation. It can significantly affect a person's comfort, confidence, and quality of life.

What Is Hyperhidrosis?

There are two main types:

  1. Primary Hyperhidrosis

    • Cause: Overactive nerves that trigger sweat glands (often idiopathic — no known cause)

    • Common areas: Hands (palmar), feet (plantar), underarms (axillary), face

    • Starts early: Usually begins in childhood or adolescence

  2. Secondary Hyperhidrosis

    • Cause: An underlying medical condition or medication

    • Common triggers: Diabetes, thyroid issues, menopause, infections, neurological disorders

    • Sweating pattern: Often more generalized and starts later in life

How Does Botox Help Hyperhidrosis?

Botox® (Botulinum Toxin Type A) blocks the chemical signals from nerves that stimulate sweat glands. When injected into the skin, it temporarily stops sweating in the treated area.

Benefits:

  • High efficacy: Reduces sweating by over 80–90% in many cases

  • Quick results: Noticeable improvement in 3–7 days

  • Lasts long: Typically effective for 4–6 months (sometimes longer)

Treatment Areas for Botox in Hyperhidrosis

  • Underarms (most common, FDA-approved)

  • Palms of hands

  • Soles of feet

  • Forehead and scalp

  • Groin (off-label use)

Procedure Overview

  • Duration: 20–30 minutes

  • Technique: Multiple small injections just beneath the skin

  • Pain level: Mild to moderate (numbing cream or ice can help)

  • Downtime: Minimal to none

Side Effects & Considerations

Area Treated Possible Side Effects Underarms Minor bruising, swelling Palms Temporary weakness in hand grip Feet Temporary soreness, harder to treat Face Risk of affecting nearby facial muscles (in rare cases)

Is Botox for Hyperhidrosis Covered by Insurance?

  • Often covered for underarm hyperhidrosis if other treatments (like prescription antiperspirants) have failed.

  • Not always covered for hands, feet, or face — depends on the insurer and medical documentation.

Alternative Treatments to Consider

  • Prescription-strength antiperspirants (e.g., Drysol)

  • Oral medications (anticholinergics)

  • Iontophoresis (electric current treatment for hands/feet)

  • Laser or microwave therapy (e.g., miraDry for underarms)

  • Surgery (sympathectomy — last resort)
