Black Widow Spider Venom

The venom of the black widow spider is reported to be 15 times stronger than that of a rattlesnake. Black widow venom is a neurotoxin. It causes systemic symptoms accompanied by slight local damage, although local necrosis does not occur.

Severity of reaction depends on the dose received and the physical condition and the age of the victim. Small children, the elderly and those with severe health conditions and compromised immune systems are more likely to experience severe symptoms. These symptoms include nausea, vomiting, faintness, dizziness, respiratory difficulties and chest pain. Some individuals believe themselves to be having a heart attack while experiencing the effects of a black widow spider bite. Blood pressure and heart rate may also be elevated.

Other people are only slightly affected by the venom of a black widow spider, experiencing minimal local pain and muscle cramps. Slight tremors, weakness and abdominal pain often mimic conditions such as appendicitis and gallbladder problems.
