Snakebite
Envenomation from a poisonous snake bite — a medical emergency requiring antivenom and immediate first aid to slow venom spread.
📝 Summary
In short: Envenomation from a poisonous snake bite — a medical emergency requiring antivenom and immediate first aid to slow venom spread.
Common causes: Bite from a venomous snake: rattlesnake, cottonmouth, copperhead, or coral snake; Severity depends on amount of venom, victim's size, protective clothing, and time to treatment; Coral snake is a neurotoxin (nerve toxin) — different action from pit vipers (hemotoxin).
First thing to try: CHECK breathing — be prepared to give artificial respiration
See a doctor if: Immediately — call the hospital ahead so antivenom is prepared.
🌿 Overview
The poisonous snakes in the U.S. are rattlesnakes, cottonmouths (water moccasins), copperheads, and coral snakes. Severity depends on how much venom is injected, the victim's size, speed of medical treatment, and the bite location. Getting to antivenom quickly is critical — home measures only buy time.
Common signs
- Extreme pain and rapid swelling at the bite site
- Puncture wounds and discoloration of skin around the bite
- General weakness, nausea, and vomiting
- Shortness of breath and blurred or dim vision
- Shock reaction
- Convulsions
- Coral snake bites may have delayed symptoms — nerve toxin causes paralysis
🔎 Why it happens
Common causes and triggers — spotting yours is often the first step to relief.

✅ What to do
Gentle, practical steps you can take at home — start at the top.
- CHECK breathing — be prepared to give artificial respiration
- Do NOT let the victim move — keep the bitten area still and lower than heart level
- Apply a light constricting band (not a tourniquet) 2–4 inches above the wound on arm or leg — loose enough to slip a finger under
- If swelling reaches the band, move it up another 2–4 inches
- If more than 1 hour from medical help: carefully make a cut 1/8–1/4 inch deep through each fang mark (lengthwise, not across) and suction for at least 30 minutes
- Wash the bite area thoroughly with soap and water
- Apply a clean sterile bandage over the wound
- Keep the victim calm and reassure them
- Give only small sips of water if the person can swallow — NEVER give alcohol
- Get to a hospital IMMEDIATELY — call ahead so antivenom can be prepared
- If possible, kill and bring the snake for identification

- Do NOT apply a tourniquet — cutting off circulation causes more damage

- Do NOT give alcohol
- NEVER make the victim walk if at all avoidable — movement speeds venom circulation
- Do NOT wait for symptoms to worsen before getting to a hospital
🩺 When to see a doctor
