Medical Treatment for hyperhidrosis1) Antipersirant
There are many different formulation but aluminium chloride is the most commonly used. This is particularly effective for the sweaty armpit but less so for the sweaty palms the anti-perspirant gets washed off easily.
Continue use for 3 to 5 days increases the effectiveness. The downside to it is that some people are allergic to this or are sensitive to the formulation.
2) Botox Injection for sweaty palms
Recently FDA has approved the use of botox to treat sweaty palms. The effect can last 3 to 9 months and has been shown to be effective. The drawn back is that it is expensive and a jab in the wrong place can injury arteries or nerves, causing numbness of the hands. The upside is that it is a fast and easy office procedure.
