There are many clinical approaches to treat hyperhidrosis. For example, topical medication, 10%-30% aluminum chloride anhydrous alcohol solution, 5%-10% formaldehyde solution or 2%-10% glutaraldehyde solution, etc., but the maintenance time is short and it is irritating to the skin. Internal medication, such as anticholinergics, antidepressants or sedatives, etc., but patients will experience side effects such as dry mouth, drowsiness, nausea and dizziness after taking them orally, and many patients are reluctant to accept them. Surgical procedures can also treat hyperhidrosis, most commonly soft tissue excision of the axillary region, subcutaneous fat aspiration of the axilla or sympathectomy, but the risks of surgery are relatively high. Botox treatment is relatively the safest and has become the gold standard for axillary hyperhidrosis treatment abroad. Of course, it does not apply to the treatment of generalized hyperhidrosis. Generally speaking, the safe dose of Botox injection is 500U, and only 100-200U is needed to treat axillary hyperhidrosis, and the effect is usually seen in 3-7 days, and the peak sweating can be reduced by more than 75% after treatment, and one treatment can generally be maintained for one year effectively. Of course, Botox treatment also has certain requirements, the patient must not have a history of coagulation disorders, infectious diseases, psychiatric disorders, no local skin disease in the axilla, no history of allergies to related drugs, and need to be at least 12 years old.
