Potassium permanganate can be used as a mild topical antiseptic to prevent infection in cuts, scrapes and sores. It is available in granules and tablets to be mixed into sterile water and applied to skin. The product can be hazardous, and people using it must be very careful.
Preparation
Potassium permanganate tablets and granules used for antiseptic are diluted to create a solution of 0.01 percent. This dilution is essential, because potassium permanganate is caustic and can cause burns.
Warning
Inhaling or swallowing potassium permanganate can be very dangerous. It must only be used on the skin and should never be applied near the eyes, nose or mouth.
Medical Use
Potassium permanganate solution is sometimes used in dermatology as a short-term treatment for weeping skin conditions such as eczema and cellulitis.
Effectiveness
A review of studies published in the August 5, 2003 issue of "Nursing Times" discusses lack of evidence for the product's effectiveness, noting that it is often used in combination with other products, which may themselves be responsible for the treatment of the wound.
Side Effects
If used for more than a few days, potassium permanganate can irritate the skin, according to another study cited in the 2003 "Nursing Times" article. Additionally, the solution can stain fabric and furnishings.
