How Dangerous Is Rattlesnake Poison?

Marjorie McAtee

Rattlesnake poison can kill large animals and humans, but rattlesnake bites in humans are very seldom deadly. The United States typically sees about 8,000 rattlesnake bites per year, but only about a dozen of those victims ultimately succumb to the poison. Even if death doesn't occur, rattlesnake poison can lead to blood clotting problems and tissue damage, and some species of rattlesnake secrete a venom that can cause paralysis. Many rattlesnake bites are known as "dry bites," or bites in which the snake fails to secrete venom. Snakes typically use dry bites as a self-defense mechanism, while fully venomous bites are often reserved for hunting prey.

The danger of a rattlesnake bite generally varies depending on the species of the snake. The Western Diamondback rattlesnake, native to the southwestern deserts of North America, is considered one of the most dangerous snakes on that continent, even though it is not considered the most venomous. The Mojave rattlesnake, whose venom is capable of causing paralysis in humans, is also considered quite dangerous. Other snakes, such as the Eastern Diamondback Rattlesnake, have more toxic venom, but are generally considered less of a threat, because they are, as a species, usually less aggressive and less likely to attack.

It is believed that bites from wild rattlesnakes are relatively rare. Experts believe that most rattlesnake bites, at least in developed countries such as the United States, come from pet rattlesnakes. Snake owners may inadvertently anger snakes while handling them, causing bites.

Rattlesnakes typically do not strike at humans or other large animals unless they feel extremely threatened. Even when rattlesnakes do strike at humans, they often do so simply as a self-defensive maneuver, to give themselves time to escape. These bites often don't inject any rattlesnake poison into the victim's flesh.

Improper first aid treatment may often be partially to blame for the negative consequences of rattlesnake bites. Folk remedies for snake bites typically endorse attempting to draw out the rattlesnake poison by cutting or sucking the bite wound. Other popular myths state that placing a tourniquet above the bite area, chilling the bite area with ice, or even applying electricity to the bite area, can stop the spread of rattlesnake poison throughout the body. In fact, these treatments can further complicate the emergency, increasing the bite victim's risk of infection, tissue damage, and loss of limbs.

The symptoms of rattlesnake bite can take several hours to appear. Emergency medical help should typically be sought right away. In general, the longer the wait for medical help, the more dangerous the poison becomes. The victim should generally be kept calm and still until help arrives. With appropriate treatment, almost all rattlesnake bite victims recover within a few weeks.

Frequently Asked Questions

How toxic is rattlesnake venom to humans?

The Western Diamondback rattlesnake is considered to be one of the most dangerous snakes in North America.
The Western Diamondback rattlesnake is considered to be one of the most dangerous snakes in North America.

Rattlesnake venom is highly toxic and can be fatal to humans if not treated promptly. The venom contains a complex mixture of enzymes, peptides, and proteins that can cause tissue damage, disrupt blood clotting, and affect the nervous system. However, with immediate medical attention and antivenom treatment, the mortality rate is relatively low, at less than 1% according to the Centers for Disease Control and Prevention.

What are the immediate symptoms of a rattlesnake bite?

It is believed that bites from wild rattlesnakes are relatively rare.
It is believed that bites from wild rattlesnakes are relatively rare.

Immediate symptoms of a rattlesnake bite include sharp pain at the site of the bite, followed by swelling, bruising, and rapid pulse. Victims may also experience difficulty breathing, weakness, nausea, and an altered mental state. It's crucial to seek medical attention immediately, as the severity of symptoms can escalate quickly.

Can you survive a rattlesnake bite without treatment?

It is important not to restrict blood flow to a rattlesnake bite.
It is important not to restrict blood flow to a rattlesnake bite.

Surviving a rattlesnake bite without treatment is possible but highly risky. The severity of the bite depends on various factors, including the amount of venom injected and the individual's health. However, untreated bites can lead to severe complications or death. Timely medical intervention significantly increases the chances of survival and recovery.

How does rattlesnake venom affect the body?

Rattlesnake venom affects the body by causing local tissue damage, coagulopathy (disruption of blood clotting), and neurotoxicity (damage to the nervous system). Symptoms can range from bleeding and muscle damage to respiratory failure and paralysis. The systemic effects can lead to organ failure if not treated with antivenom and supportive care.

What should you do if bitten by a rattlesnake?

If bitten by a rattlesnake, remain calm and immobilize the affected area. Keep it at or below heart level to slow the spread of venom. Do not apply a tourniquet or attempt to suck out the venom. Call emergency services or get to a hospital as quickly as possible for antivenom treatment. Time is a critical factor in reducing complications.

How effective is antivenom in treating rattlesnake bites?

Antivenom is highly effective in treating rattlesnake bites and is considered the standard of care. It works by neutralizing the venom, reducing its toxic effects, and preventing further damage. The sooner antivenom is administered, the better the outcome. Studies have shown that patients treated with antivenom have fewer complications and shorter hospital stays.

Many local governments and landlords have restrictions on what pets, especially venomous snakes or insects, are allowed in town or in rental properties.

This is to protect other residents and their pets from harm if the animal escapes.

Unfortunately, a lot of people acquire what are considered exotic pets illegally. This practice not only takes the animal out of its natural habitat, but it is dangerous.

It may sound incredibly obvious, but the best way to avoid getting bitten by any snake truly is by avoiding any activity that could frighten or agitate the snake.

It is easier to tell when a rattlesnake may be in a position to strike than any other snake.

If you hear a rattlesnake's signature rattle, you are likely in danger of being bitten and should run.

In addition, many venomous snakes have their venom removed before they are sold as pets or before they can come into contact with humans and other animals in zoos and exhibits.
