Hyperhidrosis is a medical condition that causes excessive sweating. Sweating is a necessary bodily function. It cools the body, preventing you from overheating. However, people who have hyperhidrosis sweat even when the body does not need to be cooled down.

At Miami Beach Laser and Aesthetics, we use Botox to temporarily treat the symptoms of hyperhidrosis in the axilla (underarms). You may be a candidate for Botox for hyperhidrosis if your sweating fails to improve with prescription antiperspirants. During the treatment, small amounts of Botox are injected into the muscle in the axilla region on both sides. Botox injections block the nerve signals responsible for sweating, stopping the sweat glands from producing too much sweat. You should notice a significant reduction in underarm sweating within the first 4 weeks after treatment. Results usually last 6-8 months before treatment needs to be repeated.

Frequently Asked Questions

Where does the sweat go?

Sweat doesn’t go anywhere or get backed up because it’s simply not produced in the areas treated with Botox®. However, sweat will continue to be produced elsewhere.

How should I prepare for the treatment?

Avoid shaving for 2-3 days before injections. Discontinue blood thinners 3 days prior to procedure to help reduce bruising.

What can I expect after treatment?

You may feel sensitivity in the area treated for a day or two. Do not use deodorant or products with perfume in the underarm area for 24 hours to prevent irritation. Avoid intense exercise and hot baths for 1 to 2 days.

What are the side effects?

Side effects from Botox injections in the underarm area include, pain at the injection site, swelling, bruising, headache, and flu-like symptoms.
