Botox injections can help prevent severe sweating by temporarily blocking the chemical signals from the nerves that simulate the sweat glands. When the sweat glands do not receive the signals, the treated area does not produce sweat.
The type of Botox used for severe sweating is Botulinum toxin, the same medicine used for wrinkles. It is commonly used for treating severe sweating of the underarms, but it can also be used on the palms of hands and soles of feet. Several injections may be needed, but the results last for almost a year. Injections are administered in a physician's office and do not demand any restrictions to work or leisure activity.
