An antiseptic for cleaning minor cuts and grazes
Cetrimide
An antiseptic used to clean minor cuts, grazes and burns and help prevent infection.
What is Cetrimide?
Cetrimide is an antiseptic used to clean minor wounds and skin, found in well-known products such as Savlon (where it is combined with another antiseptic, chlorhexidine) and Cetavlon. It acts against germs on the skin, helping to clean minor cuts, grazes and burns and reduce the chance of infection. It also has a mild cleansing action that helps lift dirt away from a wound. It is for minor, everyday wounds and first-aid use; deep, large, dirty or heavily bleeding wounds, animal or human bites, or wounds showing signs of infection should be assessed by a healthcare professional.
Education and reference only. This is a plain-language guide to Cetrimide — it deliberately contains no doses. Doses depend on the person, the brand and the reason for treatment, and belong with your prescriber. Always check the BNF, the product labelling (SmPC) and follow medical advice.
What it is
Cetrimide is an antiseptic, an agent that acts against germs on the surface of the skin, used in first-aid products to clean minor wounds. It is a familiar ingredient in products such as Savlon, where it is usually combined with another antiseptic called chlorhexidine, and in Cetavlon. It comes as creams and solutions and is used to clean minor cuts, grazes, scratches and minor burns, and to help keep them from becoming infected. It also has a gentle detergent-like cleansing action that helps wash dirt and debris away from a wound. It is an over-the-counter first-aid product for minor, everyday injuries.
How it works
Cetrimide works against germs on the skin and has a mild cleansing action a little like a soap, which helps it lift dirt, debris and some bacteria away from a minor wound. By reducing the number of germs on and around a graze or small cut, it helps lower the chance that the wound becomes infected while it heals. In products such as Savlon it is paired with chlorhexidine, another antiseptic, so the two work together to clean the area more thoroughly. It acts on the surface where it is applied, cleaning and protecting the wound rather than being a treatment taken into the body.

Practical use
Good to know
Cetrimide is a first-aid antiseptic for minor wounds: the basics still apply first, such as cleaning a wound under running water and stopping any bleeding by pressing on it. It is for minor cuts, grazes and small burns, not for deep, large, gaping or heavily bleeding wounds, animal or human bites, or anything that looks infected (red, hot, swollen, increasingly painful or oozing), all of which need proper medical care. Using strong antiseptics too often or on large areas is not advised, and it can occasionally irritate the skin, particularly if used a lot. It should be kept away from the eyes, and antiseptic solutions are for use on the skin, not for swallowing. Remember tetanus protection matters for dirty or puncture wounds, so check your vaccination status if you are unsure.
Who should not take it / use with caution
- People who have had an allergic reaction to cetrimide or chlorhexidine should not use it.
- It should not be used in or near the eyes, or swallowed.
- Deep, large, dirty or infected wounds, and bites, should be assessed by a healthcare professional rather than only self-treated.
Monitoring
- No routine monitoring is needed.
- Reviewing a wound that does not heal or shows signs of infection.
- Checking tetanus protection for dirty or puncture wounds.
Side effects
- Mild skin irritation or stinging where it is applied, especially with frequent use.
- Occasionally dryness of the skin.
- Rarely, an allergic skin reaction, in which case stop using it.
Key interactions
- There are no well-known interactions with medicines taken by mouth, as it acts on the skin.
- Some other products can reduce how well antiseptics work, so use it on a clean wound rather than over other creams.
- Tell your pharmacist about other antiseptic or wound products you are using.
Available as: Creams and solutions applied to the skin.
