Aims: Hyperhidrosis substantially impairs quality of life. Sympathectomy is often ineffective for axillary hyperhidrosis and carries a significant risk of compensatory hyperhidrosis. Botulinum toxin injection offers a temporary but effective treatment. The aim of this study was to assess the value to patients of this treatment as judged by their voluntary, self-initiated re-attendance for further treatment. Methods: A prospective database of all patients attending for Botulinum toxin injections for hyperhidrosis has been kept since October 1997. After treatment no routine review is arranged. Patients who want further injections must self refer to the clinic when they think it is necessary. Results: From October 1997 to January 2002 60 patients have received Botulinum toxin for hyperhidrosis (54 axillary, 6 plantar). 45 received their first injections more than 12 months ago and of these 31 (69 per cent) have initiated re-attendance for further treatment at a median of 10 months (IQR 7–13 months) after initial treatment. Conclusions: Botulinum toxin injection for hyperhidrosis is of sufficient value to at least 69 per cent of patients that they self-initiate repeated therapy. The median duration of efficacy is 10 months.
