Botulinum toxin is administered only by a dermatologist who has been trained and has experience with such a procedure. The injection is done in the medical practice, in about 20 minutes and does not require further restriction of professional or recreational activities.
During the procedure, with the help of a fine needle, small volumes of botulinum toxin are injected intradermally, into the sweat glands that cause excessive sweating.
The physician is the one approximating the number of injections depending on the area to be treated. Injection at the level of the palms or feet may be more painful. In this case, various local anaesthesia techniques can be used.
The effect sets in 2-14 days and lasts 6-8 months. Botulinum toxin does not permanently cure hyperhidrosis, so the symptoms will gradually return. Subsequent injections, repeated every 6-16 months, will be needed.
What is hyperhidrosis?
Hyperhidrosis is a medical condition in which sweating is excessive and occurs without these triggers. Most likely, hyperhidrosis is due to excessive stimulation of the sweat glands by the nervous system. It can be said that people suffering from this condition have their sweat glands blocked in the “ON” position.
When excessive sweating occurs without any cause, it is called primary hyperhidrosis and is more common than the secondary form, which occurs as a result of another medical condition or as an adverse effect of some medicines.
Primary hyperhidrosis is usually located on a certain part of the body, often the hands, feet, underarms or face, and is symmetrical. It often begins in childhood or adolescence, frequently in the hands and feet, and persists throughout life. Interestingly, although people with localized primary hyperhidrosis have episodes of excessive sweating at least once a week, they usually do not sweat during sleep.
