(potassium permanganate)

  • Tablets for cutaneous solution 400mg (£17.50 = 30 tablets)


  1. One tablet to be dissolved in 4 litres of water to provide a 0.01% (1 in 10,000) solution
  2. Do not use a ceramic basin or bath, keep out of contact with fabric as it stains
  3. Prescribers should avoid use of "as directed" on prescriptions. It is recommended that the dose instruction should state: "Not to be taken. To be diluted and used as a soak for the skin".
  4. A patient safety alert has been issued by NHS England to raise awareness of the risk of death or serious harm from accidental ingestion of potassium permanganate preparations. It can be fatal if ingested orally. Although packaging clearly states potassium permanganate should not be swallowed, it is very unusual for a topical preparation to come in a tablet form. When accidental ingestion has occurred, staff must treat it as a medical emergency.
