Botox for Sweating (Hyperhidrosis)

Hyperhidrosis, or excessive sweating, is a condition that can significantly impact your life, both personally and professionally. If you suffer from hyperhidrosis, you may have already been told about options including prescription strength antiperspirants, oral medications, absorbent pads, and the wardrobe tricks to try to hide your sweat marks. But, we know none of those options work very well.


In those of us who suffer from excessive sweating, or hyperhidrosis, our sweat glands are overactive, producing more sweat than is necessary to cool our body. It's often said that people with hyperhidrosis have sweat glands that are stuck in the "on" position.



Primary focal hyperhidrosis refers to excessive sweating that is not caused by another medical condition. Excessive sweating is the cause of the problem. This type of sweating occurs on specific areas of the body, described as focal areas, such as the hands (palmar), feet (plantar), underarms (axillary), and face and scalp (craniofacial). With this type of hyperhidrosis, it is uncommon to experience excessive sweating in your sleep.


Secondary generalized hyperhidrosis refers to excessive sweating that is a symptom of another medical condition or is a side effect of a medication. Most often, those of us with this type of hyperhidrosis experience excessive sweating all over our body. With this type of hyperhidrosis, it is common to experience excessive sweating in your sleep. It is recommended that if you have this type of hyperhidrosis, you be evaluated by your primary care provider or an endocrinology provider to determine the underlying source of your excessive sweating.




Botox® is clinically proven to be an effective focal treatment for hyperhidrosis. Regardless of which type of hyperhidrosis you may suffer from, Botox® can be applied to reduce sweating in the key areas of your hands, feet, underarms, face, scalp, and other areas of your body.


In one clinical study involving 322 patients with severe underarm sweating, 82% of the patients achieved more than 50% reduction in sweating. And, 50% of the patients had their excessive sweating relieved for at least 6 months. Typically, results start to be noticeable approximately 2 to 4 days after treatment, with the full effects experienced within 2 weeks. Dryness can last 4 to 12 months, but some studies have found it can last as long as 14 months.*


Botox® works by temporarily blocking the release of the chemical that is responsible for activating the body's sweat glands in the treatment area. By interrupting this chemical messenger, Botox® “turns off” the sweating mechanism at the area where it has been injected.

Our patients often ask us if it is safe to “stop” sweating. Yes, it is, because the areas we are treating are very small compared to the rest of your body. You will still be able to sweat enough from other areas of your body to be able to cool yourself. We also get asked if the sweat “builds up” or “comes out other areas” and rest assured, it doesn't. The sweat glands we are deactivating with Botox® simply shut down sweat production until the treatment wears off.

Botox®  has been shown to be safe and effective for treating excessive sweating of the armpits, hands, feet, head, face, and other body areas, such as under the breasts (inframammary). In the case of palmar (hand) hyperhidrosis, research shows that Botox is up to 90% effective in improving symptoms.* The next treatment is typically needed after 6 to 12 months.

Additional statistics from published research studies have shown that repeated treatment with Botox® is safe and effective for hyperhidrosis and consistently results in meaningful, long-lasting improvements in your symptoms, daily functioning, and quality of life.
