What to do if a black mamba bites you
SHORT ANSWERPROCEDURE · SOURCED
Call emergency services and get to a hospital, even if you feel fine. Move at least 5 m away from the snake and don't try to catch or kill it. Keep still. Take off rings, watches and anything tight near the bite. For a confirmed black mamba or Cape cobra: pressure bandage (50–70 mmHg) from the bite toward the heart, plus a splint. Don't cut, suck, pump, ice or use a tourniquet. No alcohol, aspirin or ibuprofen. If breathing stops, give rescue breaths: one every six seconds for an adult.4510

Why a mamba bite is about breathing
Black mamba venom is strongly neurotoxic. It doesn't go after the heart. It goes after the muscles you breathe with. Breathing trouble can start within half an hour, and nerve signs usually show up somewhere between fifteen minutes and two hours after the bite.123
Early signs reported in case reports include tingling lips, a strange taste in the mouth, drooping eyelids and trouble swallowing.1415
That is why the procedure looks the way it does: slow the venom down, keep the airway safe, get to antivenom, and if breathing fails, breathe for the person until a hospital can.34
This sheet covers black mamba bites in sub-Saharan Africa, following the African Snakebite Institute. North American rattlesnakes and other pit vipers are treated differently: no pressure bandage.13

The procedure: stuck in an elevator, what to do
Move away from the snake
Get at least 5 meters away. Don't try to catch or kill it, not even a dead one. Take a photo only if you can do it safely, from a distance.45
Call emergency services now
Don't wait for symptoms. Every suspected mamba bite goes to a hospital urgently, because breathing can stop.45
Keep still
Keep the person calm and still. Splint the limb. Carry them to transport if you can. Don't let them drive themselves: they can get dizzy or faint.4105
Take off anything tight
Rings, watches, bracelets and tight clothing near the bite come off before swelling starts. On a bitten ankle, that includes a tight boot.4105
Pressure bandage and splint (mamba or Cape cobra only)
For a confirmed black mamba or Cape cobra bite, wrap a pressure bandage firmly (50–70 mmHg) from the bite toward the heart, add a splint, and leave it on until hospital. Never use it on cytotoxic bites such as a puff adder.410
Don't cut, suck, pump, ice or tie it off
No cutting, no sucking, no suction pump, no ice or heat, no arterial tourniquet. A 2004 study found a suction pump removed 0.04% of mock venom.457
Nothing by mouth
No alcohol, aspirin or ibuprofen. Once swallowing gets hard, give nothing by mouth. If they vomit, turn them onto their side.5310
If breathing stops, breathe for them
Call emergency services, then give rescue breaths: one gentle breath every six seconds for an adult, with a mask if you have one, watching the chest rise. The African Snakebite Institute says chest compressions are not required for snakebite. Follow the dispatcher.4
At the hospital: polyvalent antivenom, as much as it takes
Mamba bites often need ten or more vials of polyvalent antivenom, and severe cases twenty or more, plus breathing support while the paralysis lasts.1314

“A black mamba just bit you on the ankle. It's still right there in the grass. Your hand wants a stick.”

A cornered mamba strikes repeatedly. Two bites is not a discount.1

- IF A · BELT
- OUTCOME: LIMB AT RISK
No arterial tourniquet. The Institute's only exception is someone alone, more than 90 minutes from help, certain it was a mamba or Cape cobra, with a proper tourniquet. You have a partner and a car.4

Myths vs facts
MYTH
You have twenty minutes.FACTBreathing trouble can start within half an hour; nerve signs usually appear between 15 minutes and 2 hours. Ranges vary. Plan for less, and call for help first.123
MYTH
Black mambas are black.FACTThe body is grey to dark brown. The name comes from the inky black inside of the mouth.21
MYTH
A black mamba is faster than a horse.FACTThe top recorded burst is 16–19 km/h (10–12 mph), in short bursts over level ground.6
MYTH
Cut it and suck the venom out, or use a suction pump.FACTDon't cut and don't suck. In a 2004 study a suction pump removed 0.04% of the mock venom.47
MYTH
Tie your belt above the bite.FACTNo arterial tourniquet. The only exception is alone, more than 90 minutes from help, certain it was a mamba or Cape cobra, with a proper tourniquet.4
MYTH
A drink of brandy helps.FACTNo alcohol, aspirin or ibuprofen. Once swallowing is impaired, nothing by mouth.53
MYTH
Snake oil works on snakebite.FACTClark Stanley sold his liniment for 'bites of animals, insects and reptiles' around 1905. In 1917 federal investigators found mineral oil, beef fat, red pepper and turpentine. No snake. He was fined $20.89
MYTH
One vial of antivenom is enough.FACTMamba bites often need ten or more vials; severe cases twenty or more.13
EXPERTS DISAGREE
Pressure bandage: it depends on the snake
Black mamba, Cape cobra (Africa)
Pressure bandage, 50–70 mmHg, from the bite toward the heart, plus a splint, until hospital.4
Neurotoxic snakes in general (WHO)
Pressure immobilization is only recommended for neurotoxic snakes that don't cause local swelling.10
Cytotoxic bites (puff adder)
Never use a pressure bandage.4
North American rattlesnakes
Toxicologists say pressure immobilization is not recommended before hospital.13
This is geography, not a coin toss. Know your snake. Or at least your continent. If you don't know, call for help and follow local guidance.
REAL CASE · NOT STAGEDCALDER CO.
One real case
In January 1998 Kruger National Park ranger Danie Pienaar was tracking white rhino alone when a black mamba bit him just below the knee. He tried to cut the bite, tied his belt above the knee, walked back to his pickup and drove to a tourist road, where the first car took him on. He reached hospital about two hours after the bite. He never received antivenom; a ventilator breathed for him for about two days, and he recovered.11

Questions people search
What should you do if a black mamba bites you?
Call emergency services and get to a hospital urgently, even if you feel fine. Move at least 5 m away from the snake, keep still, take off rings and anything tight, and for a confirmed mamba apply a pressure bandage (50–70 mmHg) from the bite toward the heart with a splint. Don't cut, suck, ice or use a tourniquet. If breathing stops, give rescue breaths, one every six seconds for an adult.
How long do you have after a black mamba bite?
There is no single number. Breathing trouble can start within half an hour, and nerve signs usually appear between 15 minutes and 2 hours after the bite. Twenty minutes is a movie number. Plan for less time than you think and call for help first.
Should you use a tourniquet for a black mamba bite?
No. The African Snakebite Institute advises against arterial tourniquets. Its only exception is someone alone, more than 90 minutes from medical help, certain it was a black mamba or Cape cobra, using a proper tourniquet. Otherwise use a pressure bandage and splint.
Why is it called a black mamba if it isn't black?
The body is grey to dark brown. The name refers to the inky black inside of its mouth, which it shows when threatened.
Is a black mamba faster than a horse?
The fastest recorded black mamba burst is 16–19 km/h (10–12 mph), over short distances on level ground, according to Guinness World Records.
Does a snakebite suction pump work?
No. In a 2004 study with volunteers, a suction pump removed 0.04% of the mock venom. Don't cut or suck the bite either.
