Plantar hyperhidrosis, also known as sweaty feet, can have severe social effects on children and adolescents. Therapeutic options include antiperspirants, iontophoresis and surgical interventions (e.g., sympathectomy). Surgical interventions are not recommended however with conservative methods being tried first. Botulinum type A toxin is approved for axillary hyperhidrosis in adults only. The aim of the study was the determination of effect and safety of botulinum type A toxin in plantar hyperhidrosis in juvenile patients.
Conclusion: Botulinum type A toxin seems to be a safe secondary treatment option for plantar hyperhidrosis in adolescents aged 12 and older. A dose of 75-100 U per sole resulted in a good therapeutic effect of variable duration in most patients. There were no severe side-effects.
