Hyperhidrosis means excessive sweating. In most people, it occurs symmetrically on specific areas of the body, such as the underarms, hands, feet or head. Hyperhidrosis can cause a great degree of emotional embarrassment and may affect the quality of a person’s life.
There are a variety of effective over the counter antiperspirants. A stronger formulation of the most common ingredient, aluminum chloride, is also available by prescription. For patients who do not respond to antiperspirants, botulinum toxin (Botox®) can be injected into the underarms, hands or feet to decrease the sweating. The effects of Botox® may last 4 to 6 months, at which time retreatment is necessary. There are also oral medications available in select cases.
