Botox for hyperhidrosis temporarily blocks the acetylcholine signal to eccrine sweat glands in the treated area. It is FDA-cleared for primary axillary (underarm) hyperhidrosis and used off-label for palms, feet, and the scalp hairline.
Unlike antiperspirants or systemic medication, Botox targets the gland directly without whole-body effects. Results are temporary and repeatable, about 4 to 6 months per cycle. SOM provides documentation for insurance reimbursement.

No. Botox temporarily reduces nerve signals that activate sweat glands in the treated area. It can significantly reduce sweating for appropriate candidates, but it is a maintenance treatment and not a permanent cure. Results and duration vary by area and individual response.
The underarms are the most common treatment area. Palms, soles, and the scalp or hairline may also be considered off-label, but comfort, dosing, function, and medical suitability differ by area. A dermatologist-trained SOM provider confirms whether the requested area is appropriate during consultation.
It may be considered when excessive sweating interferes with clothing, work, social situations, or daily comfort and topical antiperspirants have not provided enough control. A dermatologist-trained SOM provider, reviews symptoms and medical history to confirm candidacy and rule out reasons to seek another evaluation.
Sweat reduction often lasts about 4 to 6 months, although some patients experience a shorter or longer response. Duration depends on the area, dose, severity, and individual metabolism. Repeat treatment is planned when sweating returns and the medical review still supports it.
Some insurance plans may cover treatment for diagnosed primary hyperhidrosis after other measures have been tried, but coverage is not guaranteed. Requirements, prior authorization, and reimbursement vary. Cosmetic or convenience-based treatment is generally self-pay.
Many patients begin to notice reduced sweating within 1 to 2 weeks, with the full response developing over several weeks. The treated area should be reassessed after the expected onset period rather than immediately after injection.
Hyperhidrosis is a medical treatment. These related options cover separate cosmetic concerns.
