Removal of the leech

Salt, salt water or vinegar will cause an actively sucking leech to vomit and fall off. A leech will usually fall off after 20 minutes of attachment without any treatment.

DO NOT pull the leech off as the skin may be torn and ulceration may follow or parts of the jaw may remain and set up infection. Applying heat to the leech (e.g. applying a hot coal or lit cigarette) may result in burns to the patient so is not recommended.
Treatment

Wash with soap and water.

Apply a cold pack if there is significant pain or swelling.

Apply pressure if there is bleeding from the bite.

Seek medical attention if the area becomes infected or if a wound or ulcer develops.

Even if you have never been bitten by a leech before, watch for the following symptoms, they may indicate a serious allergic or anaphylactic reaction, which requires urgent medical attention:

* red blotches on the skin or an itchy rash over the body
* swelling in parts of the body away from the bitten area, especially the lips and around the eyes
* feeling faint, light-headed or dizzy
* breathing difficulties: wheeze, shortness of breath, chest tightness
