Funnel-web spider bites are extremely poisonous. Seek immediate medical attention. Call the Poison Control Center for guidance. Apply a bandage and firm pressure over the bite, and keep the affected area still, if possible, to prevent the venom from spreading. Loosen clothing and remove rings and other constrictive jewelry.

Determine the following information:

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

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.

The health care provider will measure and monitor the patient's vital signs, including temperature, pulse, breathing rate, and blood pressure. The wound will be treated as appropriate.

The patient may receive:

• Breathing support
• Fluids through a vein (by IV)
• Medications to treat symptoms
• Antivenin medication, if available

Funnel-web spider bites can be life threatening, especially in children, and must be treated quickly with antivenin by an experienced doctor. Even with appropriate and timely treatment symptoms may persist for several days to weeks.
