Severe compensatory hyperhidrosis following thoracic sympathectomy successfully treated with low doses of botulinum toxin A.

AbstractCompensatory hyperhidrosisis an adverse effect of thoracic sympathectomythat can be debilitating, which is why an efficient treatment is demanded. Botulinum toxinis an emerging treatment, not well known yet. We report two cases of compensatory hyperhidrosisfollowing thoracic sympathectomywhich were both treated with low doses of botulinum toxinA. The patients, a male and a female, noted a high level of satisfaction with the abolishment of sweating that was maintained up to 10 months. We consider that low doses of botulinum toxinA is a well tolerated, safe and effective treatment for compensatory hyperhidrosisand should be offered as an alternative treatment.
