Most spider bites cause only minor injury. Bites from a few spider species can be dangerous.

Seek medical care immediately if:

• You were bitten by a dangerous spider, such as a black widow or a brown recluse
• You're unsure whether the bite was from a dangerous spider
• You have severe pain, abdominal cramping or a growing wound at the bite site
• You're having problems breathing or swallowing
• The area of the sore has spreading redness or red streaks.

To take care of a spider bite:

• Clean the wound with mild soap and water. Then apply an antibiotic ointment three times a day to help prevent infection.
• Apply a cool compress over the bite for 15 minutes each hour. Use a clean cloth dampened with water or filled with ice. This helps reduce pain and swelling.
• If possible, elevate the affected area.
• Take an over-the-counter pain reliever as needed.
• If the wound is itchy, an antihistamine, such as diphenhydramine (Benadryl) or certirizine (Zyrtec) might help.

For pain and muscle spasms, your doctor might prescribe pain medicine, muscle relaxants or both. You might also need a tetanus shot.
