General Spider Bite Treatment

If a spider has bitten you, try to capture the spider to bring it in to medical professionals. Identifying the spider is a key step to treating the bite, and a spider bite can never be completely diagnosed without the culprit to identify.

• Stay calm

• Wash area with soap and water (unless bitten by a Brown Recluse spider – keep those dry)

• Use a damp, cold cloth or a cloth filled with ice to reduce swelling

• Elevate area if possible

• Tie a snug bandage above bite to slow spread of venom (ensure this is not too tight!)

• Do not attempt to remove venom

• Take acetaminophen or an antihistamine to reduce swelling and pain

• Seek professional medical attention as soon as possible
