Doctor, can botox be used for excess sweating in teens.. Read on...

Sometimes I'm asked to help. Frankly, I am not sure why more do not ask me in Texas .... JR

Summary:
80-93% have a 75% plus response that lasts 4-6 months.

A Prospective, Nonrandomized, Open-Label Study of the Efficacy and Safety of OnabotulinumtoxinA in Adolescents with Primary Axillary Hyperhidrosis.

Abstract

OBJECTIVE:

To evaluate the efficacy and safety of onabotulinumtoxinA in adolescents with primary axillary hyperhidrosis.

METHODS:

This 52-week, multicenter, nonrandomized, open-label study was conducted in 141 adolescents ages 12 to 17 years with severe primary axillary hyperhidrosis. Patients could receive up to six treatments with onabotulinumtoxinA (50 U per axilla), with re-treatment occurring no sooner than 8 weeks after the prior treatment cycle and no later than 44 weeks after the initial treatment cycle. The primary efficacy measure was treatment response, based on self-assessed hyperhidrosis severity following the first two treatments using the 4-point Hyperhidrosis Disease Severity Scale (HDSS). Other efficacy measures included spontaneous resting sweat production and health outcomes.

RESULTS:

Fifty-six (38.9%) participants underwent one treatment, 59 (41.0%) underwent two, 20 (13.9%) underwent three, 6 (4.2%) underwent four, and 3 (2.1%) underwent five. OnabotulinumtoxinA significantly improved HDSS scores and decreased sweat production compared with treatment cycle baselines. Seventy-nine patients (54.9%) responded to treatment based on HDSS criteria. From 56.6% to 72.3% of patients experienced a two-grade or more improvement at 4 and 8 weeks after each of the first two treatments. The majority (79.4%-93.2%) had a 75% or greater reduction in sweat production at week 4 (treatments 1-3). The median duration of effect for responders ranged from 134 to 152 days. Using quality of life measures, health outcomes improved markedly. Eight patients (5.6%) had mild or moderate treatment-related adverse events. No unexpected safety signals were observed in this study. Neutralizing antibodies to onabotulinumtoxinA did not develop.

CONCLUSION:

OnabotulinumtoxinA injections provided beneficial effects in adolescents with primary axillary hyperhidrosis.
