A tight plastic strap or tourniquet is not the correct first aid for most snakebites. In fact, it can make the injury much worse.
When a tourniquet is tied too tightly, it cuts off blood flow to the arm or leg. This can quickly damage muscles, nerves, and skin because the tissues are no longer receiving enough oxygen. That is why the arm may become pale, blue, or even black. If left on for too long, it can lead to permanent tissue damage and, in severe cases, even amputation.
So, what should you do immediately after a snakebite?
1. Stay calm and reassure the victim.
Panic increases the heart rate, which may cause venom to spread through the body more quickly. Keeping the person calm is one of the most important first steps.
2. Move away from the snake safely.
Do not try to catch, kill, or handle the snake. Many people are bitten a second time while attempting this. If it can be done safely, take a photo of the snake from a distance, but only if there is no risk.
3. Keep the bitten limb still.
Immobilize the arm or leg with a splint or sling if possible, and keep it at a comfortable level. Avoid unnecessary movement because muscle activity can help spread venom.
4. Remove rings, watches, bracelets, or tight clothing.
Swelling can develop rapidly, and these items may become dangerously tight.
5. Get medical help immediately.
Call emergency services or go to the nearest hospital as soon as possible. Antivenom is the only specific treatment for many venomous snakebites, and early medical care greatly improves outcomes.
What should you NOT do?
❌ Do not apply a tight tourniquet.
❌ Do not cut the wound.
❌ Do not try to suck out the venom.
❌ Do not apply ice or electric shocks.
❌ Do not drink alcohol or caffeine.
❌ Do not try to wash the bite excessively if medical professionals may need venom traces for identification (follow local medical advice).
A note about pressure bandages
Some people have heard about wrapping the bite with a bandage. This is not the same as a tourniquet. A pressure immobilization bandage is only recommended for certain types of snakebites in specific regions (such as some neurotoxic snake species in Australia) and should be applied correctly. An incorrectly applied tight bandage can also cause harm.
The most important takeaway
The best first aid after a snakebite is to keep the person calm, keep the bitten limb still, avoid harmful treatments like tight tourniquets, and get emergency medical care immediately. Quick professional treatment gives the best chance of a full recovery while reducing the risk of serious complications.
