Aluminium chloride hexahydrate is prescribed by doctors when regular antiperspirants fail. It is applied at bedtime daily for around 10 days, then once a week as maintenance. The aluminium salts in the preparation collect in the sweat ducts and block them, diminishing sweating over time until no further treatment is required. This treatment works quite well for those with excessive underarm sweating but may not be satisfactory for those with palm or sole sweating. The main side effect is irritation which can sometimes be overcome by reducing the frequency of use or with mild steroid lotions. Other home care tips include: 1. Drink plenty of water to replace lost body fluids. 2. Wash the face and body with soap and water as cleansing twice daily usually removes the bacteria and yeast that cause odour. Some people may require a few days washing with an antiseptic soap. 3. Aroma oils can be added to the bath water. 4. Choose clothing that is loose and light coloured and change into freshly washed clothing often. Loose clothing allows passage of air, which reduces sweating and light coloured clothes will not show sweat marks. Similarly wear materials that breathe freely like cotton, while avoiding those that don’t like silk and nylon. 5. Wash armpit and groin with solution of vinegar in water to reduce body odour. 6. Wash armpits and hairy areas with tea water as the tannic acid in tea has antiperspirant properties. 7. Shaving or laser hair removal in the armpits can help to control odour. 8. Reduce intake of caffeine and stop medications that may be the cause of excessive sweating. 9. Take a balanced diet. Avoid excessive intake of spicy food to reduce sweating. 10. Several natural remedies such as soaking baking soda and corn starch on cotton pads and dabbing on underarms after bath can help reduce sweating. If these remedies don t work, you can try botox treatments.
