Botulinum toxin injection for hyperhidrosis
Botulinum toxin injections for the treatment of hyperhidrosis are an effective treatment option when other treatments have not produced satisfactory results. These injections work by temporarily blocking the chemical signals in the nerves that stimulate the sweat glands.
Botulinum toxin type A injections are a safe, quick, and relatively long-lasting method for treating symptomatic excessive underarm sweating in specific areas such as the armpits, palms of the hands, and soles of the feet.
In the literature, patients report high satisfaction, improved emotional and physical well-being, reduced activity limitations, and increased comfort.
How is botulinum toxin injection carried out in hyperhidrosis?
The Geneva botulinum toxin treatment consists of a series of injections, usually not very painful, using a fine needle. The duration of the treatment is a few minutes. Patients can resume their activities normally after the injections. 10 minutes before the injection, we apply an anesthetic cream to improve patient comfort. We also mix the neurotoxin with a local anesthetic which further improves comfort during the injection.
Results are visible between the third and seventh day. You are seen again in consultation after two weeks. A “touch-up” can be offered at this time to perfect the result. After four to six months, the effect fades and the session must be repeated.
And the side effects?
Side effects are rare: pain, redness or bruising may occur in the injected area. The doctor with his experience will make sure to avoid these latter inconveniences as much as possible. Allergies are exceptional.
FAQ
What mechanism of action?
The toxin inhibits the release of acetylcholine from the sympathetic nerves that innervate the eccrine sweat glands, thereby preventing overstimulation and excessive sweating.
How long does the effect last?
The effects of botulinum toxin last on average about six to nine months.- Axillary Hyperhidrosis: Botulinum toxin injections are particularly useful for underarm sweating.
Palmar and Plantar Hyperhidrosis?
Although most commonly used for axillary hyperhidrosis, botulinum toxin injections can also be effective in treating excessive sweating of the palms and soles of the feet.
Who is the ideal candidate?
Patients who have failed or have an intolerance to topical antiperspirants (such as aluminum chloride) may benefit from botulinum toxin injections.
How is botulinum toxin injected in the treatment of hyperhidrosisAdministration?
Dermatologists, neurologists, or pediatricians may administer botulinum toxin type A for severe primary hyperhidrosis of the armpits in patients ages 12 and older.
Why does the effect of botulinum toxin injection last longer in some people compared to others?
The effect on the face lasts 4 – 6 months. The duration depends on several factors including the dose of botulinum toxin Geneva and the “expressivity” of the patient are among the most important factors. When it comes to dose, there is an optimal dose. If you inject more than this dose, the effect will not be stronger and will not last longer. This dose varies from one patient to another. It is the doctor’s experience that will determine this optimal dose. Furthermore, the more expressive a patient is, the less the effect of botulinum toxin will last over time. Finally, tolerance to the appearance of the first signs of a reduction in the effect of botulinum toxin varies from one individual to another. Some wait longer than others to consult.
What is the difference between the different toxins (Botox, Vistabel, Dysport and Xeomin)?
The differences are not significant for patients. Indeed, a good doctor can achieve optimal effect with any of the products we have mentioned. However, differences exist, for example, we know that the diffusion of Dysport is greater in tissues. Some doctors prefer this effect and therefore use this product.
How long does the effect of botulinum toxin last?
After the injection, a plateau is reached approximately 1 week. This plateau lasts between 4-6 months. The duration of the plateau varies from one individual to another. The factors that influence the duration are multiple and not all of them are known. We know, for example, that the more expressive a person is, the shorter the duration. A healthy lifestyle would increase the duration. Stress and smoking seem to shorten the duration.
Remember to consult a healthcare professional to determine the most suitable treatment approach for each patient. Botulinum toxin injections offer a valuable option for managing hyperhidrosis, improving patients’ quality of life and reducing the impact of excessive sweating.
