The neurotoxin alpha-latrotoxin targets the peripheral and autonomic nervous systems, causing massive, indiscriminate presynaptic release of neurotransmitters such as acetylcholine and norepinephrine

Clinically, affected individuals classically present with immediate localized puncture pain followed by severe, progressive muscle rigidity and spasms that frequently involve the abdomen, back, and chest, often accompanied by diaphoresis, hypertension, and tachycardia While envenomation can affect any population, pediatric, elderly, and pregnant patients are at the highest risk for severe systemic complications, including respiratory compromise, severe hypertension, and cardiac dysfunction
