Quick answer
What is Snake bite?
Snake bites vary enormously in seriousness depending on the species and where in the world they happen. In the UK, the only native venomous snake is the adder, and its bite, while it can cause pain, swelling and feeling unwell, is rarely dangerous and very rarely fatal, though it should always be assessed.
- How it is treated: First aid for a snake bite focuses on keeping the person calm and still (to slow the spread of any venom), keeping the bitten limb still and at or below heart level, removing rings, watches or tight clothing near the bite (in case of swelling), and getting to medical help quickly.
- Self-care: When in areas with snakes, wear boots and long trousers, watch where you place hands and feet, and do not handle snakes.
- When to seek help: Seek medical help for any snake bite.
What it is
Snake bites vary enormously in seriousness depending on the species and where in the world they happen. In the UK, the only native venomous snake is the adder, and its bite, while it can cause pain, swelling and feeling unwell, is rarely dangerous and very rarely fatal, though it should always be assessed. In many other parts of the world, however, venomous snake bites are a significant cause of serious illness and death, and are a genuine medical emergency. The effects of a venomous bite depend on the snake and can include local pain and swelling, and, with some species, effects on blood clotting, the nervous system (causing weakness or breathing difficulty), or tissue damage. Not all bites from venomous snakes inject venom ("dry bites"). Because the risk and treatment depend so much on the snake and location, and because serious effects can develop, any snake bite — especially abroad — should be taken seriously and medical help sought.
How it is treated
First aid for a snake bite focuses on keeping the person calm and still (to slow the spread of any venom), keeping the bitten limb still and at or below heart level, removing rings, watches or tight clothing near the bite (in case of swelling), and getting to medical help quickly. Importantly, harmful old first-aid measures should be avoided: do not cut the wound, try to suck out venom, apply a tight tourniquet, or apply ice — these can cause harm. Trying to catch or kill the snake is not advised, but noting its appearance (or a photo from a safe distance) can help identify it. In hospital, treatment depends on the snake and the effects, and may include observation, supportive care, and antivenom for significant envenoming from certain species. For UK adder bites, most people recover well with assessment and supportive care. When travelling in areas with dangerous snakes, prevention — wearing suitable footwear, being careful where hands and feet are placed, and knowing what to do — is valuable. The key message is to stay calm, avoid harmful traditional remedies, and seek prompt medical care.

When to get help
When to see a doctor
Seek medical help for any snake bite. Abroad, treat a venomous snake bite as an emergency and get to hospital quickly. Call 999 for severe symptoms — spreading swelling, difficulty breathing, collapse, or signs of a severe allergic reaction. Do not cut, suck, apply a tourniquet, or use ice.
Not sure how urgent it is? It is always OK to call NHS 111 for advice, day or night.
