Spider Bite

How common are spider bites? — Spider bites are very rare. Most spiders’ fangs are not strong enough to poke through your skin. Also, spiders do not usually bite unless they are crushed between you and another object.

Most people who think a spider bit them were usually bitten by a different insect, such as a tick. Also, some skin infections can look like a spider bite.

How dangerous are spider bites? — Most spider bites are harmless. The poison that most spiders inject when they bite (called “venom”) is not toxic to people. But a few types of spiders can give painful bites. In rare cases, the bites get infected or cause other serious symptoms.

Some types of dangerous spiders live only in Australia or South America. But some are found in countries all over the world, including the United States.

What are the symptoms of a spider bite? — Symptoms include a small, red, raised bump on the skin. The bite might itch or burn.

Some bites do not start to hurt until a few hours after the bite. The pain can range from a slight prickly feeling to very bad pain.

In rare cases, spider bites can cause:

●Redness, swelling, and pus

●Flu-like symptoms such as feeling tired and sick to your stomach, throwing up, and fever

●Sweating

●Very bad muscle pain

●Very bad belly pain

●Dead tissue – When this happens, the center of the red bump turns a dark red, blue, or black, dries out, and forms a sore. This is called “necrosis” and can happen several days after a spider bite. The sore is usually about the size of a quarter but can grow larger. Most heal after a few weeks but some last for months.

What should I do if a spider bites me? — If you are bitten by a spider, you should:

●Wash the area that was bitten with soap and water.

●Put a cold gel pack, bag of ice, or bag of frozen vegetables on the painful area every 1 to 2 hours, for 15 minutes each time. Put a thin towel between the ice (or other cold object) and your skin.

●If you can, keep the bitten area raised up above the level of your heart.

●Try to figure out what type of spider bit you.

Should I see a doctor or a nurse? — See a doctor or nurse if you get any of the rare symptoms listed above.

How are spider bites treated? — Treatment involves cleaning the area well and taking medicines if needed. Depending on your symptoms, your doctor or nurse might recommend:

●Medicine for pain, such as ibuprofen (sample brand names: Advil, Motrin)

●Medicines to treat muscle spasms, called benzodiazepines

●A tetanus shot – Tetanus is a serious infection that causes muscle spasms and stiffness. It is caused by bacteria that can get in your body through a cut, scrape, or bite.

●Antibiotics – If there are signs of infection (such as a fever, red skin, or pus coming from the bite), a doctor will prescribe antibiotics. But most spider bites do not get infected.

People who have dead tissue because of a bite sometimes need surgery to remove the dead tissue.

People who are bitten by a widow spider and have severe pain and muscle spasms that don’t get better with other treatments sometimes get a special medicine called “antivenom.”

What can I do to reduce the chances of getting a spider bite? — To avoid a spider bite, be extra careful in places that dangerous spiders live
