What to do if you are bitten by a Brown Recluse Spider?

The recommended treatment for most actual brown recluse bites (the ones that do not become traumatic) is simple first aid: RICE therapy.

• Rest
• Ice
• Compression
• Elevation

Antibiotics work against bacteria and have no effect on spider venom. However, regardless of the causative agent, it is wise to seek medical attention if you feel that it is warranted. (Source R. S. Vetter).

The patient should be taken to the emergency room for treatment. The bite may not appear to be very severe and may take some time to progress to a more severe state. However, treatment is important to minimize complications. If possible, bring the spider to the emergency room for identification.

Expectations (prognosis)

"About 10% of brown recluse bites cause moderate or greater tissue damage and scarring, but the vast majority heal very nicely without medical intervention. There is still not one proven death from brown recluse bite (a person was bitten by a spider caught in the act and properly identified). While there are several highly probable deaths reported in children, these are extremely rare occurrences, about one every decade or so. " (Source R. S. Vetter)

The recluse spiders' venom is a necrotoxin, which means it destroys tissue cells. A bite may initially cause a sharp sting or may cause no pain at all. Pain may develop within the first several hours, or even up to 6 to 8 hours after the bite, possibly becoming severe. The victim may experience general feelings of discomfort, malaise, or nausea, and sometimes intense itching.In severe cases there is sloughing off of the skin and formation of a blister, then an ulcer in the area of the bite. There may be a reddish to purplish color in a bullseye patter to the skin area around bite, with a subsequent sloughing off of the skin, leaving a raw deep area of exposed tissue. These can take weeks to heal in some cases. Chills or fever and sweating may be experienced.
