Karen Bassett of Southern Oregon Pediatrics in Medford, a registered nurse with more than 20 years of experience, offered treatment advice.
A spider bite may have two distinct puncture marks and may swell and bruise.
- Wash the bite with soap and water.
- Use a cool compress for pain and take an oral antihistamine, such as Benadryl, for itching.
- Try to retain the spider for identification if possibly poisonous. (In Oregon, only black widow and hobo spiders are of concern.)
The reaction may last for 48 hours, but if the site is not improving or worsening after that time, Bassett recommends seeking medical attention. As with all bites or stings, seek emergency medical attention if experiencing difficulty breathing or weakness.
