The most common methods for stopping sweating in the armpit or underarm area are antiperspirants and deodorants. Products such as Mitchum based can be helpful. Stronger aluminium hydroxide preparations like Driclor are applied at night. These can be helpful in stopping sweat for a few months. However, a tolerance can be generated in which case the effectiveness diminishes. Also, patients can be put off by the skin irritation that can quite often occur. Other home treatments such as iontophoresis are effective but again expensive and time-consuming and need to be done 2-3 times a week. It is the preferred method of choice for sweaty hands and feet.
