What causes hyperhidrosis?

The nerves that trigger the sweat glands become overactive causing profuse sweating.

​

What are the different types of hyperhidrosis?

​

Hyperhidrosis for which the underlying cause is not determined is known as primary hyperhidrosis. Hyperhidrosis associated with certain medical conditions such as diabetes, heart attack, cancer, infectious disease, an overactive thyroid or some medication is known as secondary hyperhidrosis.

​

Can Botox be used for treatment of hyperhidrosis?

Botox can be used for treatment of severe primary hyperhidrosis of the underarms, hands, feet, face and other areas of the body such as under the breasts.

​

How are the Botox injections administered?

Using a fine-needled syringe, small quantities of Botox are injected just below the skin surface throughout the area noted to have excessive sweating. Anesthesia in the form of nerve blocks, ice or vibrational anesthesia may be provided to ease any discomfort. The injections can be performed around 15-20 minutes as an outpatient procedure.

​

What is the mechanism of action of Botox?

Botox acts by temporarily blocking the action of the nerves which stimulate the sweat glands.

​

How often can the treatment be repeated?

Treatments can safely be repeated every 7-16 months to remain effective.
