Talcum Powder and Corn Starch Powder are suitable for mild hyperhidrosis. Apply between the toes, under the breasts and other skin folds. Frequent washing using a deodorizing soap can reduce the smell and discomfort, however overuse of soaps can result in dermatitis. Treatment available from a specialist Oral propantheline reduces sweating, but unfortunately can cause blurred vision, dry mouth, and constipation. A dusting powder containing diphemanil may be used for mild hyperhidrosis.
Iontophoresis is available at some hospital departments.
A low electrical current is passed across the skin surface daily for several weeks and stops sweat production. Visits are then required weekly or less often. Irritation sometimes results, and occasionally dermatitis. Botulinum toxin injections into the affected area, particularly the armpits, can reduce or even stop sweating for three to six months. Unfortunately the effect may not be permanent, and is accompanied by undesirable skin warmth and dryness.
