Which spider has an antivenom that can be given for acute symptoms?

• A. Brown recluse
• B. Black widow
• C. Tarantula
• D. Huntsman spider

Answer: (B)

The key idea is that only some spider bites have a specific antivenom, and it’s used to treat acute, systemic symptoms. Black widow venom contains latrotoxin that can cause rapid, widespread neurotoxic effects such as severe cramps, muscle rigidity, sweating, tachycardia, and hypertension. In more serious cases, a specific antivenom against Latrodectus species can rapidly neutralize the venom and improve symptoms. The other spiders listed either do not have a routinely used antivenom, or their bites are typically less dangerous and managed with supportive care. So the spider with an antivenom available for acute symptoms is the black widow.
