How long does botox for sweating take to work for underarm sweating?

Short answer

Botox for sweating usually begins reducing underarm sweating within days, with the effect becoming clearer during the following weeks.

This answers one question. It is not a diagnosis and does not replace an assessment by a licensed doctor.

How the treatment works

Botulinum toxin is injected into selected underarm skin. It temporarily interrupts the nerve signals that activate sweat glands in the treated area. Sweating may reduce progressively rather than stop immediately, and untreated areas can continue to sweat. The response can vary with injection pattern, sweating severity, and whether another condition or medicine is contributing.

What to do after treatment

Keep the underarms clean and follow the clinic’s instructions about washing, deodorant, exercise, and heat exposure. Do not rub or press injection sites unnecessarily. Note when dampness, clothing changes, and odour begin to improve. If the expected change has not started after the review period given by your clinician, arrange a review rather than requesting extra injections independently.

When to get medical advice

Call the treating clinician for spreading redness, increasing warmth, pus, severe pain, or fever at an injection site. Seek urgent care for trouble breathing or swallowing, widespread weakness, or rapidly worsening symptoms after treatment. New symptoms away from the underarms should be reported, even if the injection sites look normal.

Useful questions

Ask when your response should be reviewed, how the treated area will be mapped, what temporary effects to expect, and which alternatives are suitable if sweating remains troublesome.

Questions people ask

Will botulinum toxin stop sweating everywhere?

No. It acts in the injected area, so sweating elsewhere may continue.

What if underarm sweating has not changed yet?

Follow the review timing supplied by your clinician and arrange an assessment if the response is later or less than expected.
