What are the benefits of Botulinum Neurotoxin A (BoNTA) (Haytox) for patients with hyperhidrosis?

For patients suffering from hat fever, or hyperhidrosis, BoNTA (Haytox) can be a beneficial treatment option, particularly when other treatments have failed to provide adequate relief. Given the potential for significant improvement in quality of life, I recommend considering BoNTA for patients with moderate to severe hyperhidrosis, regardless of age, provided they have no contraindications to the treatment. The typical dose for hyperhidrosis treatment is 50-100 units per axilla, with the treatment repeated every 6-12 months as needed. It's essential to note that while BoNTA can be effective, it may not completely eliminate sweating and can have side effects such as bruising, pain, or flu-like symptoms. As a second-line intervention, aluminum chloride or aluminum zirconium-based antiperspirants may be considered for patients who are not suitable candidates for BoNTA or have mild hyperhidrosis. In all cases, a thorough medical evaluation and discussion of the potential benefits and risks are necessary before initiating treatment.
