Home Treatment:

Seek immediate emergency medical treatment. Wrap ice in a washcloth or similar material and place it on the bite area. Leave it on for 10 minutes and then off for 10 minutes. Repeat this process.

Before Calling Emergency:

Determine the following information:

• Patient's age, weight, and condition
• Time the bite occurred
• Area where the bite occurred
• Type of spider, if possible

Poison Control, or a local emergency number:

The National Poison Control Center (1-800-222-1222) can be called from anywhere in the United States. This national hotline number will let you talk to experts in poisoning. They will give you further instructions.

This is a free and confidential service. All local poison control centers in the United States use this national number. You should call if you have any questions about poisoning or poison prevention. It does NOT need to be an emergency. You can call for any reason, 24 hours a day, 7 days a week.

What to expect at the emergency room:

The health care provider will measure and monitor the patient's vital signs, including temperature, pulse, breathing rate, and blood pressure. Symptoms may be treated with a variety of therapies, including:

• Blood pressure drugs
• Muscle relaxers
• Pain medicines

In severe cases, anti-venin medication to reverse the effect of the poison will be given. However, this drug can cause serious allergic reactions.

Expectations (prognosis):

Severe symptoms usually go away within 2 to 3 days, but milder symptoms may persist for several weeks. Death in a normally healthy individual is very rare. Young children may not survive a bite.
