Hyperhidrosis is the medical term for excessive sweating. The problem may be limited to the armpits, but often the palms and soles also sweat excessively. Hyperhidrosis becomes noticeable after puberty. Stressful situations such as examinations, job interviews, or an important date often aggravate the sweating. Sometimes, it takes almost nothing for the sweating to start and once it starts, it usually worsens until the affected person can get away from everyone else and cool down. Unfortunately, most over the counter antiperspirants do not control hyperhidrosis.
Aluminum Chloride Hexahydrate
Treatment aims to control the excessive sweating; it is not a permanent cure. A topical agent known as aluminum chloride hexahydrate in absolute alcohol is available in Canada without a prescription under the name of Drysol.
Sweat Inhibiting or Neuromodulator injections such as Botox ® usually reduce hyperhidrosis for an average of 6 months after 1 or 2 treatments.
Other Treatment Options
Usually localized applications of aluminum chloride hexahydrate provide satisfactory sweat control. When this regime does not work, other options may include internal medications (such as anticholinergics), electrophoresis, a technique utilizing a device called the Drionic machine, dilute formalin (for sweaty feet). In very rare cases surgery is necessary to remove the sweat glands or cut the nerve responsible for their stimulation.
