What is the evidence for the use of potassium permanganate preparations?

Varinder Rai, Regional Medicines Information Manager, London Medicines Information ServicePublished

This medicines Q&A summarises the published evidence for the use of potassium permanaganate in the following conditions: weeping or blistering secondary to eczema, cellulitis, and leg or foot ulcers.

Only three small studies were identified in the published literature that investigated potassium permanganate in the management of the above conditions.

Overall, there is a lack of published evidence for the use of potassium permanganate preparations to aid the management of weeping or blistering conditions secondary to eczema, cellulitis, leg or foot ulcers, and pseudomonas infections of the skin/wounds.
