Botox for Excessive Sweating Underarms: A Comprehensive Guide

Excessive sweating, also known as hyperhidrosis, can be an embarrassing and uncomfortable condition for many people. One effective solution to this problem is the use of Botox injections. In this article, we will explore the benefits, procedure, and potential side effects of using Botox for excessive sweating underarms. We will also provide answers to common questions and concerns about this treatment.

What is Hyperhidrosis?

Hyperhidrosis is a medical condition characterized by excessive sweating, which can affect various parts of the body, including the underarms, palms, soles, and face. This condition can significantly impact a person’s quality of life, leading to social anxiety, embarrassment, and even professional limitations. According to the International Hyperhidrosis Society, approximately 3% of the population suffers from hyperhidrosis.

How Does Botox Work for Excessive Sweating?

Botox, or botulinum toxin type A, is a neurotoxin that works by blocking the release of acetylcholine, a neurotransmitter responsible for stimulating sweat glands. When injected into the underarm area, Botox effectively reduces the amount of sweat produced by temporarily paralyzing the overactive sweat glands. This treatment has been approved by the U.S. Food and Drug Administration (FDA) for the treatment of severe primary axillary hyperhidrosis (excessive underarm sweating) in patients who have not found relief from antiperspirants.

What to Expect During the Botox Procedure


Before undergoing Botox injections for excessive underarm sweating, you will need to consult with a qualified medical professional to determine if this treatment is suitable for you. During the consultation, your medical history, current medications, and any previous treatments for hyperhidrosis will be discussed. The doctor will also examine your underarm area to assess the severity of your sweating and determine the appropriate dosage of Botox.


Before the procedure, you should avoid shaving your underarms for at least 24 hours to minimize the risk of infection. You should also avoid consuming alcohol and taking blood-thinning medications, such as aspirin or ibuprofen, for a few days before the treatment to reduce the risk of bruising.

The Procedure

The Botox procedure for excessive underarm sweating is relatively quick and straightforward. The doctor will first clean the underarm area and may apply a topical anesthetic to minimize discomfort during the injections. A small amount of Botox will then be injected into multiple points in the underarm area, targeting the overactive sweat glands. The entire procedure typically takes about 30 minutes to complete.

Recovery and Results

After the Botox injections, you may experience some mild discomfort, redness, or swelling in the treated area. These side effects are usually temporary and should subside within a few hours to a couple of days. You can resume your normal activities immediately after the procedure, but you should avoid strenuous exercise and excessive heat exposure for at least 24 hours.

The results of Botox for excessive underarm sweating are not immediate. You may start noticing a reduction in sweating within a few days, but the full effects of the treatment may take up to two weeks to become apparent. The results of Botox injections for hyperhidrosis typically last between four and six months, after which the treatment can be repeated as needed.

Potential Side Effects and Risks

Botox injections for excessive underarm sweating are generally considered safe and well-tolerated. However, as with any medical procedure, there are potential side effects and risks associated with this treatment. Some of the most common side effects include:

– Pain, redness, or swelling at the injection site
– Temporary muscle weakness or numbness in the treated area
– Headache
– Flu-like symptoms

In rare cases, Botox injections can cause more serious side effects, such as difficulty breathing or swallowing, muscle weakness in other parts of the body, or an allergic reaction. If you experience any severe or persistent side effects after the treatment, you should contact your healthcare provider immediately.
