Black Widow Spider Bite
WHAT YOU NEED TO KNOW:
The venom from a black widow spider is poisonous. Symptoms of a reaction to the venom start about 30 minutes after the bite. Symptoms are usually mild and stop within a few days, but severe symptoms that last several days are possible. Venom can spread from the bite to other parts of your body. It can damage your muscles, nerves, or organs.
You may need any of the following:
- NSAIDs help decrease swelling and pain or fever. This medicine is available with or without a doctor's order. NSAIDs can cause stomach bleeding or kidney problems in certain people. If you take blood thinner medicine, always ask if NSAIDs are safe for you. Always read the medicine label and follow directions. Do not give these medicines to children under 6 months of age without direction from your child's doctor.
- Prescription pain medicine may be given. Ask how to take this medicine safely.
- Muscle relaxers may be given to relieve cramps or spasms.
- Antivenom may be given if your symptoms are severe or you are at increased risk. Antivenom can help slow or stop your symptoms.
- Take your medicine as directed. Contact your healthcare provider if you think your medicine is not helping or if you have side effects. Tell him if you are allergic to any medicine. Keep a list of the medicines, vitamins, and herbs you take. Include the amounts, and when and why you take them. Bring the list or the pill bottles to follow-up visits. Carry your medicine list with you in case of an emergency.
Elevate your wound:
Elevate your wound above the level of your heart as often as you can. This will help decrease swelling and pain. Prop the bitten body part on pillows or blankets to keep it elevated comfortably.
Apply ice to your wound for 15 to 20 minutes every hour or as directed. Use an ice pack, or put crushed ice in a plastic bag. Cover it with a towel before you apply it to the wound. Ice helps prevent tissue damage and decreases swelling and pain.
Care for your wound as directed. Carefully wash the wound with soap and water. Dry the area and watch for signs of infection, such as fever, redness, and swelling.

Write down your questions so you remember to ask them during your visits.
