Sterile honey-impregnated wound dressings: a plain-English patient guide

What medical honey is

Medical honey — sometimes called medical-grade honey — is honey that has been sterilised (almost always by gamma irradiation), tested for its antibacterial activity, and packed as a single-use medical device. It is regulated in the same way as other wound dressings, not as food. The most common types you will meet on a UK ward are Manuka-based products (Activon, Algivon, Medihoney) and Revamil-based products (L-Mesitran).

How it helps a wound

Honey works on a wound in four ways at once:

• Draws out fluid (osmosis). Honey is mostly sugar. It pulls fluid out of the wound bed, which lifts dead tissue (slough) and reduces swelling.
• Acidifies the wound. Honey is naturally acidic (pH around 3.5–4.5). Most wound bacteria prefer a more alkaline environment, so the acidity slows them down.
• Releases small amounts of hydrogen peroxide as it meets wound fluid — enough to be antibacterial, not enough to damage healing tissue.
• Contains methylglyoxal (MGO) in Manuka honey, which adds a non-peroxide antibacterial effect that keeps working even when peroxide is broken down by the wound.

The combination is why honey can be effective against bacteria that have become resistant to common antibiotics, including MRSA.

When clinicians use it

Tissue-viability and district nurses commonly reach for medical honey on:

• Sloughy or smelly wounds that need debriding without surgery
• Pressure injuries (bed sores) and leg ulcers
• Diabetic foot ulcers
• Minor burns once cooled and assessed
• Surgical wounds that are slow to close or have started to weep
• Skin tears, traumatic grazes and donor sites

What the dressing feels like

Most people feel nothing unusual. A minority feel a short stinging or drawing sensationfor the first 15–30 minutes — this is the osmotic pull described above and is a sign the dressing is working, not that something is wrong. The feeling usually settles. Tell your nurse if it is severe, lasts more than an hour, or is paired with new redness spreading away from the wound.

Side effects & cautions

• Short stinging on application (common, usually settles).
• Increased fluid at the wound for the first few dressings — this is expected; the outer dressing may need changing more often.
• True honey allergy is rare. Bee-venom allergy is a different thing and is not usually a reason to avoid honey dressings.
• Diabetes: the amount of sugar absorbed through a wound is very small and does not normally affect blood-glucose control. Monitor as usual.
• Do not use food-grade honey from a jar on an open wound — it is not sterile.

Medical honey vs the honey in your kitchen

Using medical honey at home

Products such as Activon Tube, Algivon dressings, Medihoney gel and L-Mesitran Soft are available from UK pharmacies and online medical suppliers. For small, clean wounds at home, follow the packaging instructions and change the outer absorbent dressing whenever it becomes saturated. See your GP or nurse if the wound is deep, on a high-risk site (foot, face, near a joint), showing spreading redness, or not improving within two weeks.

Removing dead or infected tissue from a wound so healthy tissue can grow.

Slough

Yellow / cream stringy dead tissue on the surface of a wound.

Exudate

The fluid that leaks from a wound.
