Potassium Permanganate

The use of this drug is counter-indicated:

- the risk of its being ill-used is too high
- it is not on the WHO list of essential drugs.

Indications

- Superficial wounds
- Seeping eczema
- Mycoses, especially of the toes (athlete's foot).

Presentation

- Dark violet crystals to be dissolved
- Tablets to be dissolved: they come in various dosages 0.25 g, 0.5 g and 1 g.

Dilution

- Dilute 0.01% (100 mg to 1 litre of water).
- The concentration must be precise:

• if it is too concentrated, it is caustic
• if it is too diluted, it is ineffective.

A balance is necessary to obtain the right concentration from the crystals.

Precautions

- Handle dry product or concentrated solutions with care (skin burns and risk of explosion if brought into contact with an easily oxidisable product).

- Take precautions to ensure that the tablets are not swallowed. Do not keep them with oral tablets. INGESTION IS VERY SERIOUS: risk of perforation of the digestive tract.

- Repeated application dries the skin.

Comments

- This product offers no particular advantages other than that it is not very costly.

- Its use is counter-indicated because of the constant errors made in diluting from crystals and the risks of the tablets being swallowed.

- Preservation:


• Dry product: protected from the air (well-closed recipient)
• Solution diluted for use: maximum one week.
