Quick Answer
After a spider bite, remain calm, remove any constricting items, and wash the bite area with soap and warm water to reduce the risk of infection. Monitor for signs of severe reaction, such as difficulty breathing, rapid heartbeat, or extreme pain. Seek medical attention immediately if symptoms persist or worsen.
Assessing the Bite
When assessing the spider bite, pay close attention to the type of spider, the location and severity of the bite, and any visible signs of envenoming such as redness, swelling, or blistering. In cases of suspected brown recluse or black widow spider bites, seek medical attention immediately due to the potential for serious systemic reactions. If you are unsure of the spider’s identity, it is still crucial to monitor the bite area closely.
Treating the Bite
To treat the spider bite, clean the affected area with soap and warm water, then apply a topical antibiotic ointment to reduce the risk of infection. Use a cold compress or an ice pack wrapped in a cloth to help reduce swelling and ease pain. Keep the bite area elevated above the level of the heart to reduce swelling and promote blood flow. Avoid applying heat, as this can worsen the envenoming process.
When to Seek Medical Attention
If you experience any of the following symptoms after a spider bite, seek medical attention immediately: increasing pain or swelling, difficulty breathing, rapid heartbeat, dizziness or fainting, nausea or vomiting, or any signs of allergic reaction such as hives or itching. In cases of suspected brown recluse or black widow spider bites, or if you are unsure of the spider’s identity, it is always best to err on the side of caution and seek medical attention.
