Relief of hyperhidrosis (underarms, hands, feet)
This medication is used to relieve hyperhidrosis, or excessive sweating, that occurs in specific areas such as the underarms, hands, and feet. These symptoms can cause discomfort in daily life, and this medication helps improve them.
Apply an appropriate amount to the affected area in the evening and wash it off with water the next morning. Use it once every night until sweating stops, and if symptoms improve, reduce to 1–2 times a week.
This medication should not be used by individuals who are allergic to this medication or any of its components. When using this medication, do not apply it to skin that has been shaved within 12 hours or to damaged or irritated skin. Depilatories should not be used within 12 hours before or after using this medication, and care should be taken to avoid contact with mucous membranes such as the eyes, nose, and mouth. If contact with the eyes or mucous membranes occurs, rinse immediately with clean water. Pregnant women should consult their physician before using this medication, as reproductive toxicity has been reported in animal studies, thus caution is required. Women who are breastfeeding should also consult with a professional before using this medication and should take care to avoid contact with the breast area. If contact occurs, clean any traces of the medication from the breast before breastfeeding. For children under 12 years old, the safety and efficacy of this medication have not been established, and consultation with a professional is necessary before use. If any abnormal symptoms such as skin irritation, rash, itching, or redness occur while using this medication, discontinue use immediately and consult a professional. As sweating decreases, skin irritation may occur, so it is advisable to stop use if symptoms worsen. Using this medication more frequently than recommended can lead to increased skin irritation, so caution is advised. If accidentally ingested, symptoms such as nausea, vomiting, diarrhea, and burning sensations in the mouth and throat may occur; in such cases, rinse the mouth thoroughly and follow the instructions of medical personnel. This medication contains ethanol, which can be systemically absorbed in case of overdose, hence caution is required. Excessive use may cause skin peeling or redness, and applying a moisturizer or 1% hydrocortisone cream may be helpful if these symptoms arise. The treatment area must be completely dry before application, as this medication can react with water and irritate the skin. Apply only to the treatment area, and avoid direct contact with clothing, metals, or precious metals. This medication must be stored in a light-sensitive container, and it is important to keep it in a cool place below 25 degrees to maintain its effectiveness. Transferring to another container may lead to misuse or degradation of the medication's quality.
