How does botox for sweating work?

Botulinum toxin type A is placed in small injections across the area being treated, such as the underarms, palms, or another site affected by hyperhidrosis. The medicine acts at the connection between nerves and sweat glands, reducing the release of the chemical signal that starts sweating. It does not remove the glands or correct every cause of sweating, so the effect is limited to treated skin and needs medical planning. Body odour may improve when dampness is reduced, although odour itself can have other causes.

A clinician should confirm whether your sweating is primary hyperhidrosis or linked to a medicine or another condition. Share your health history, medicines, allergies, muscle or nerve disorders, and any swallowing or breathing problems. The treatment area may be mapped before injections. Discuss alternatives such as iontophoresis or microwave sweat gland treatment when they fit your symptoms. Follow instructions about cleansing, activity, and review after treatment.

Seek urgent help for trouble breathing or swallowing, widespread weakness, facial swelling, or a severe allergic reaction after treatment. Contact the clinic for increasing redness, warmth, drainage, severe pain, or weakness that is unexpected for the treated area. New, sudden, or night-time sweating with fever, weight change, chest symptoms, or fainting also deserves medical assessment.

Ask which area will be treated, whether your sweating needs investigation first, what alternatives are suitable, and how to recognise a treatment reaction.
