Underarm Botox for hyperhidrosis
Specialized evaluation for excessive underarm sweating and candidates for botulinum toxin/Botox™ treatment.
Underarm Botox for hyperhidrosis may significantly reduce excessive underarm sweating for several months in selected patients. Dr. Rafael Garza Castillón provides thoracic specialist evaluation, HDSS and HidroQoL questionnaires, and review of previous treatments to determine whether botulinum toxin is appropriate.
This information is educational and does not replace a medical consultation. Botox™/botulinum toxin treatment must be individualized.

Non-surgical option
What is underarm Botox?
Underarm Botox, or botulinum toxin applied to the underarms, is an option for patients with axillary hyperhidrosis who sweat more than normal even without heat or exercise. In appropriate candidates, it may significantly reduce sweating for several months.
Before treatment, the medical evaluation should confirm hyperhidrosis, measure severity and review the impact on daily life, work and social confidence.
Candidacy
Who may be a candidate?
Candidacy depends on the severity of sweating, previous treatments, affected area and quality-of-life impact. Some patients may improve with stronger antiperspirants; others may benefit from botulinum toxin and, in selected cases, surgery may be discussed.
The consultation explains expected benefits, approximate duration, aftercare, possible side effects and when another treatment option should be considered.
Objective measurement
HDSS and HidroQoL before and after
HDSS and HidroQoL questionnaires help objectively evaluate hyperhidrosis severity and quality-of-life impact. They also help document improvement after treatments such as underarm Botox™.
This approach supports clearer decisions and follow-up instead of relying only on subjective impressions.
Stepwise options
Underarm Botox vs. thoracic sympathectomy
Underarm Botox is not surgery. It is a local option to reduce underarm sweating for a period of months. Minimally invasive thoracic sympathectomy is reserved for selected patients with moderate to severe hyperhidrosis and important psychosocial impact, especially after trying several lines of treatment.
During consultation, patients can understand when non-surgical options are reasonable and when a definitive surgical discussion may be appropriate.
