Black Widow Spider Bite

The quick bite of the black widow spider has the power to paralyze large prey. Because the venom of a black widow contains toxins that affect the nervous system, victims much larger than the biting spider may experience paralysis.

Humans bitten by black widows sometimes experience only minimal effects. However, some individuals may experience severe symptoms that could lead to death. A victim's age and health condition are important factors in severity of symptoms. Small, children and elderly patients are more at risk, as well as those with compromised immune systems and heart conditions.

After being bitten, the area surrounding the bite becomes reddened and local swelling may occur. Within one to three hours, intense, spasmodic pain affects the limbs, abdomen and back of bite victims. This condition can persist for more than 48 hours and may be accompanied by nausea and profuse perspiration. If untreated, black widow spider bites can result in fatalities preceded by tremors, convulsions and unconsciousness.

Individuals experiencing extreme reactions should seek medical attention immediately upon recognizing a black widow bite. Doctors commonly treat these bites with calcium gluconate and anti-venom treatments. Antiseptics applied directly to the bite site also prevent infection.
