Spider Bites

Though many people are afraid of spiders, they rarely bite people unless threatened. Most spider bites are harmless. Occasionally, spider bites can cause allergic reactions. And bites by the venomous black widow and brown recluse spiders can be very dangerous to people.

If you are bitten by a spider, you may see a reaction similar to that of a bee sting, including redness, pain and swelling at the site. To treat a spider bite:

  • Wash the area well with soap and water
  • Apply an ice pack or a wet compress to the area
  • Take over-the-counter pain medicine, if needed
  • Consider using antihistamines for severe swelling
  • Seek medical treatment for small children and adults with severe symptoms

  • Black widow spider
  • Brown recluse spider
  • Funnel-web spider bite
  • Tarantula spider

Suicide is the tenth most common cause of death in the United States. People may consider suicide when they are hopeless and can't see any other solution to their problems. Often it's related to serious depression, alcohol or substance abuse, or a major stressful event.

People who have the highest risk of suicide are white men. But women and teens report more suicide attempts. If someone talks about suicide, you should take it seriously. Urge them to get help from their doctor or the emergency room, or call the National Suicide Prevention Lifeline at 1-800-273-TALK (8255). It is available 24/7.

Therapy and medicines can help most people who have suicidal thoughts. Treating mental illnesses and substance abuse can reduce the risk of suicide.
