How to manage axillary hyperhidrosis in adolescents?

Management of Axillary Hyperhidrosis in Adolescents

For adolescents with axillary hyperhidrosis, a stepwise approach starting with topical antiperspirants containing aluminum chloride should be used as first-line treatment, followed by botulinum toxin A injections for those with inadequate response to topical therapy.

First-Line Treatment Options

Topical Therapies

• Aluminum chloride-based antiperspirants (20-25% concentration)
  • Apply to completely dry skin at bedtime
  • Wash off in the morning
  • Initial application: daily for 1 week
  • Maintenance: 1-2 times weekly as needed
  • Common side effects: skin irritation, burning sensation

Lifestyle and Supportive Measures

• Appropriate clothing

  • Loose-fitting, cotton garments to minimize friction and allow airflow 1
  • Avoid tight clothing that may worsen symptoms

• Proper hygiene

  • Regular cleansing with antiseptic washes to reduce bacterial load
  • Daily bathing with antibacterial soap

• Hydration management

  • Maintain adequate hydration (for adolescents: up to 1.0-1.5L per hour during activity) 2
  • Avoid excessive caffeine and spicy foods which may trigger sweating

Second-Line Treatment

Botulinum Toxin A Injections

• Indicated when: Topical treatments fail after adequate trial (typically 1-2 months)
• Efficacy: Reduces sweat production by 71-96% 3
• Dosing:
  • 100-200 units per axilla 4
  • Intradermal injections spaced 1-2 cm apart in affected areas
• Duration of effect: 4-12 months (average 7 months) 5
• Safety profile: Well-tolerated in adolescents with minimal side effects
• Patient satisfaction: 98% of patients would recommend this therapy 4

Procedure Details

1. Map hyperhidrotic areas using iodine-starch test
2. Clean area with antiseptic
3. Administer intradermal injections (multiple small injections throughout affected area)
4. Results typically appear within 2-5 days
5. Maximum effect achieved within 2 weeks 4

Treatment Algorithm

1. Start with topical aluminum chloride (20-25%)

   • Apply nightly to dry skin for 1 week
   • If effective, continue 1-2 times weekly for maintenance

2. If inadequate response after 4-6 weeks:

   • Consider botulinum toxin A injections
   • 100-200 units per axilla
   • Repeat every 6-12 months as needed

3. For severe cases unresponsive to above treatments:

   • Refer to dermatologist for consideration of more invasive options

Special Considerations for Adolescents

• Age-appropriate counseling about the condition to reduce psychological impact
• School accommodations may be necessary (extra time for changing clothes, etc.)
• Psychological support as hyperhidrosis can significantly impact quality of life and social interactions
• Treatment goals should focus on improving quality of life and reducing social embarrassment

Monitoring and Follow-up

• Assess response to treatment after 2-4 weeks
• Monitor for side effects (skin irritation with topicals, muscle weakness with botulinum toxin)
• Adjust treatment plan based on response and seasonal variations
• Consider impact on quality of life and psychological well-being at each visit

Pitfalls to Avoid

• Delaying treatment: Axillary hyperhidrosis can significantly impact adolescents' quality of life and social development
• Inadequate application of topicals: Must be applied to completely dry skin at bedtime for maximum efficacy
• Underestimating psychological impact: The condition can cause significant emotional distress and social isolation
• Overtreatment: Start with less invasive options before progressing to more aggressive treatments
